Single-lens reflex and photography lights
DSLR and camera lights played an important role in the field of photography. ** 1. DSLR camera ** 1. ** Equipment cost ** - There was a huge difference in the price of the camera bodies. For a full-frame DSLR camera or a mirrorless camera body, the price of a high-quality camera body ranged from a few thousand yuan to tens of thousands of yuan. - The lens was also an important part of the investment. For example, the 85mm f/1.8 or f/1.2 fixed-focus lens used for portrait photography cost from a few thousand to tens of thousands of yuan. Moreover, the camera technology was updated quickly. The photographer might regularly upgrade the body or lens in pursuit of better image quality, higher IQ performance, or new functions. This was a continuous expense. 2. ** The role in photography ** - It was the core device for capturing images. It could focus light onto the sensor through the lens to form an image. - It can be shot under different lighting conditions, but in low light, backlighting, backlighting, and other poor lighting conditions, it may be necessary to use auxiliary equipment such as camera lights or flashes to improve the shooting effect. 3. ** Usage Scenarios ** - In the daytime, it was very good to shoot scenery, people, buildings, and other subjects. - In low-light environments such as indoors, nights, or rainy days, if you don't use a camera light or flash, there may be problems such as increased noise and unclear subjects. ** 2. Photographic Lights ** 1. ** Equipment cost ** - For beginners or those with limited budget, a set of basic lighting equipment (such as one or two external flashes, softboxes, or umbrellas) may only cost a few thousand dollars. - If you want to pursue professional effects, invest in high-end continuous light sources, multiple lights, various light control accessories (such as beehives, grids, large soft light boxes), and lighting controllers, the total cost may be more than tens of thousands of yuan. Although the lighting equipment upgrade cycle was longer than the camera, in order to adapt to different scenes and styles, new equipment and accessories might need to be added continuously. 2. ** The role in photography ** - In low-light environments, such as indoors, at night, or on rainy days, the photography lamp can provide enough fill light to prevent the photo from being overexposed or uneven, and maintain the clarity of the details of the picture. - Portrait photography under backlighting could balance the brightness difference between the background and the background, ensuring that the outline of the person was clearly visible. It could also make the brightness of the subject and the background more balanced when shooting against the light. - It could also be used to create special artistic effects. By adjusting the angle, intensity, and color temperature, it could produce unique effects such as shadows, backlighting, and background blurring. 3. ** Usage Scenarios ** - In portrait photography, whether it was indoor or outdoor backlighting, backlighting scenes, photography lights could effectively improve the performance of the main character. - In product photography, good lighting could greatly improve the quality of the work and highlight the details and texture of the product. The DSLR camera and the camera light complemented each other in the process of photography. A reasonable combination of the two often brought the best results. Read more exciting novels for free
Single-lens reflex photography
There were a few things to pay attention to when doing a Hong Kong style single-lens reflex photography: 1. ** Understand the characteristics of Hong Kong style **: Hong Kong style photos are usually rich in color, thick filter, strong contrast, and yellowish highlights. You also have to consider the character's expression, eyes, composition, and the story expressed in the photo. 2. ** In terms of composition **: Choose a suitable composition method, composition is the basic element of shooting. 3. ** Color environment **: The Hong Kong retro style requires a high level of color and lighting. You can add more red to enhance the retro feel and try to make the picture more colorful. 4. ** Light Usage **: - When the contrast between light and shadow was strong, use side backlighting to increase the sense of penetration. The use of light scattering would make the color tone of the photo soft. - You can use street lamps as the ambience light, or you can use light sticks to create a special color tone (such as green). You can also set up a 40-Watt COB light about two meters in front of the character. - Try to shoot the face facing the light as much as possible. This way, it would be easier to capture the light in the eyes of the character and improve the overall expression of the picture. 5. [Blur the background]: You can blur the background and focus on the character to highlight the character's personality and achieve the theme of the photo. 6. ** Use of props **: You can use old TV sets, posters of Miss Hong Kong's beauty pageant, iron wire beds, old picture frames, sunglasses, mirrors, Victoria lamps, flannel sofas, bamboo fences, cheongsams, fans, pearl earrings, radio, tape, roses and other props to add to the atmosphere of Hong Kong. 7. ** Character Make-up and Styling **: - In terms of makeup, women's exquisite sword-shaped eyebrows and iconic "fiery red lips" were more representative. Their makeup did not need to be too white, and their eyebrows could refer to wild eyebrows. Men did not pay much attention to their makeup, but their hairstyles were "30 - 70" or "back hair". - In terms of hairstyle, women could comb their hair into braids, tie up their hair in full curls, or push their hair to one side as much as possible. If the hair was not thick enough, women could use wigs or wig patches. - In terms of clothing matching, one could refer to the previous outfits of Hong Kong and Taiwan actresses, such as white T-shirts with wide-legged pants or halter skirts, or choose bright red dresses to capture the intellectual and mature femininity, etc. Men could choose shirts, jeans, sweaters, and other items. 8. ** Picture Effect Creation **: - It was a common effect for many Hong Kong-style portraits to make the image appear hazy and blurry. It could be achieved by putting stockings on the lens, applying some vaseline lipstick or transparent sunblock. - It could capture close-ups of parts such as eyes, collarbones, hands, lips, etc., making the character more comfortable and relaxed. The effect was advanced and beautiful. 9. ** Position Selection **: - Only the side of the character's body was shot. With his hands on his shoulders and his head raised, his eyes naturally looked at the camera. Through his eyes, he could express his emotions, haggardness, intellectual charm, and so on. - He could also sit sideways at the intersection of the two colors, with his hands on the ground behind him and his legs bent, or he could sit on the patterned fabric sofa with a book in his arms. 10. ** Use of filter **: If you really don't have a suitable scene or prop, you can also use a yellow filter to show the Hong Kong style. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single lens reflex photography
If it was about DSLR photography, the following were some of the key points for DSLR photography: ** 1. Selection of shooting mode ** 1. ** Portrait Shooting ** - **A (Aperture priority mode)**: suitable for portrait shooting. In this mode, the aperture size could be adjusted manually. A large aperture (such as f/1.8, f/2.8, etc.) could make the background blur, highlight the main body of the character, and obtain a natural blurring effect. It could also increase the amount of light in the case of insufficient light. - **M file (full manual mode)**: Can be used for portrait photography. The photographer had to manually set the sensitivity, aperture, shutter speed, white balance, exposure compensation, focus, color temperature, and other parameters. This mode was suitable for taking portraits under complex lighting conditions, such as indoor lighting or scenes that used specific lighting to create a special atmosphere. 2. ** Shooting of moving objects ** - **S (Shutter priority mode)**: Adjusts the shutter speed. The faster the shutter speed, the more it can freeze the instant image of a moving object. It is suitable for capturing people, animals, or sports events in motion. 3. ** Scenery Shooting ** - **M (Full Manual Mode)**: It is very useful when shooting scenes such as sunrise, sunset, night scene, sea of clouds, starry sky, etc. For landscape photography, you can manually adjust the sensitivity, aperture, shutter speed, and other parameters according to the desired effect. For example, when shooting the starry sky, high sensitivity, large aperture, and slow shutter speed were needed (generally, a tripod was needed to keep the camera stable); when shooting sunrise and sunset, the parameters had to be adjusted according to the light intensity and the desired color effect. ** 2. Shooting Points ** 1. ** In terms of composition ** - ** Find a unique subject **: Choose a good-looking or oddly-shaped subject. This kind of subject will be easily remembered by the audience. - ** Use geometric composition **: For example, a triangular composition can make the picture full of geometric beauty. When shooting a picture that contained multiple elements, the elements could be arranged and combined to form a triangle to increase the stability and beauty of the picture. 2. ** Focus ** - Portrait and animal photography: If you are shooting portraits or animals, pay attention to the light in your eyes. This will make the subject more vivid. For animal photography, you can use methods such as feeding to get the animal to cooperate so that the eyes of the subject have a bright reflection. 3. ** Picture level ** - When shooting a scene, you can increase the layering of the picture by changing the angle of view. For example, lowering the angle of view, using the front and back arrangement of the characters or the changes in reality to create a sense of hierarchy. ** 3. Later adjustments ** Most of the photos taken by the DSLR camera were original photos. They couldn't completely restore the scenery seen by the human eye, so they needed to be retouched later. He could use the phone APP to adjust the light, shadow, contrast, saturation, atmosphere, color temperature, clarity, and other parameters of the photo to adjust the photo to his liking. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
photography homework, single-lens reflex photography
Here are some tips on how to use DSLR cameras for photography homework: ** 1. The camera settings ** 1. ** Shooting Mode ** - Try to use manual mode. Manual mode allowed the photographer to precisely control the camera's parameters according to the specific shooting scene and needs, while automatic mode might not be able to meet some special shooting requirements. 2. ** White Balance Setting ** - If there was a color difference in the photo, it might be caused by the use of household light bulbs or the camera's default automatic white balance setting was inaccurate. In this case, you can try to set the white balance to daylight mode, or try to take a photo in all other white balance modes to compare which mode is closer to the actual color. 3. ** Setting of the sensitivity ** - For example, the higher the value, the brighter the photo, but at the same time, the more likely it was to have noise. It needed to be adjusted together with other values (such as aperture, shutter speed, etc.). For example, for a small object, you can set it to 200, and for a large object, you can set it to 400. 4. ** Exposing settings ** - The exposure value was displayed as-0.7,-0.3, 0, 0.3, 0.7, 1, etc. The higher the value, the brighter the photo. You can set the exposure value to 0.3 during the test shoot. 5. ** Shutter Speed Setting ** - Shutter speeds such as 1/60, 1/80, 1/100, 1/125, etc. The smaller the decimal value, the slower the speed, the more light entering the camera, and the brighter the photo taken. 6. ** Aperture setting ** - The smaller the aperture value, the larger the aperture. The more light entered, the brighter the photo. The larger the aperture value, the smaller the aperture. The less light entered, the darker the photo. It was important to note that the aperture and aperture value were in inverse proportion. The value on the camera was the aperture value, and the result after the adjustment was the aperture. For example, a photo taken with an aperture value of 3 is brighter than a photo taken with an aperture value of 6. ** 2. Shooting Techniques ** 1. ** Composing Skills ** - Diagonal composition, triangular composition, and other methods could be used to make the picture more beautiful and stable. He could also try the full-body composition method. - When shooting, you can stagger the composition or capture the moment when the character walks by to create a picture-in-picture effect. 2. ** Basic principles of filming ** - To make the photo have a clear and distinct theme, whether it was a person, a still life, or an event, it needed to be clearly expressed to avoid ambiguity or all-encompassing. - A good photo must draw attention to the subject so that the audience could immediately notice the core of the photographer's intention. - It made the photo more concise and removed those elements that couldn't set off the subject or even distract attention. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Introduction to single-lens reflex photography
The following is some basic knowledge about DSLR photography: ** 1. Choosing a camera ** 1. ** Follow the principle of having enough ** - For novices who mainly took photos, if the budget was limited, there was no need to blindly pursue a full-frame bucket machine. Many full-frame bucket machines had comprehensive functions, but they might cause some functions to be idle. For example, for people who didn't often shoot videos, the video function would be wasted. Half-frame models such as the APSC could meet the needs of many novices. For example, Fuji had done very well in the entry-level market and had not launched a full-frame model. - When purchasing entry-level cameras in 2024, the APSC camera still had some advantages, such as the importance attached by various manufacturers, such as the upgrade of the filter in the Sony-ZV-E10II, the cost-effective model Z30 launched by Nikon, and the half-frame opening of Canon's radio bayonet. 2. ** Choose the camera first, then consider the body ** - Full-frame lenses were usually much more expensive than half-frame lenses. For example, when the prices of the A6700 (half-frame) and A7M3 (full-frame) were similar, many novices would choose the full-frame model due to price factors, but the cost of the full-frame lens would be higher when changing the lens later. - Some brands of full-frame lenses had limitations. For example, Canon's full-frame radio frequency mount was not open, and there were few third-party lenses, while the original lens was expensive. As for Fuji and Sony, there were more third-party lenses, Nikon's z-mount was open, and third-party zooming and fixed-focus lenses were gradually becoming more abundant. Pantheon lenses were basically enough, but the Sima 28 - 70 had a premium and was not easy to buy. 3. ** Take the usage of the surrounding veterans as reference ** - If there were experienced photographers around with a lot of lenses, he could borrow their lenses after he familiarized himself with the camera and changing the lens. ** 2. Basic camera operation ** 1. ** Shutter Operation ** - Pressing the shutter was divided into two steps. First, press it gently halfway (Half Past). At this time, the viewfinder autofocus symbol would flash. If there was a sound prompt, it would make a "beep" sound. This was the camera's autofocus and light measurement. After this process was completed, he pressed it a little harder. When you press the shutter, bend the first section of your right index finger downward. Use light force. Do not knock hard, hit hard, or shake. Try to find support, such as a tripod. If there is no tripod, you can use tables, big stones, pillars, trees, corners, etc. At the same time, you must control your breathing. Take a breath before pressing the shutter, hold your breath and press it again. Exhale after pressing it. If one were to shoot a moving object, due to the camera's "time lag," one had to consider the amount of time in advance. The brain had to analyze and predict the other party's movements and rhythm. 2. ** Aperture setting ** - The aperture was a device that controlled the amount of light that entered the camera through the lens. It could be adjusted by rotating the adjustment ring on the lens or the knob on the body of the digital camera. The larger the aperture, the greater the amount of light entering, the smaller the depth of field, and the smaller the f-value. When the light was strong, the aperture was reduced, and when the light was dim, the aperture was opened. When taking a portrait, if only one person was taken, the large aperture could be adjusted to blur the background and highlight the main body. When taking a group photo, a small aperture of about f8 could be set to ensure that everyone's face was clear. 3. ** Light sensitivity (USB)** - The high or low sensitivity of the camera meant that when the exposure value was the same, the higher the sensitivity of the camera, the faster the shutter speed could be used to obtain the same exposure. In a bright environment during the day, the sensitivity should be adjusted to 100 to ensure better image quality. When the environment is dark, the exposure should be increased to ensure normal exposure. However, even in a very dark environment, the sensitivity should not exceed 6400. When it is too dark, you can use the fill light. 4. ** Shooting Mode ** - ** Fully Automatic Mode (Auto)**: It is suitable for beginners or when you need to take a quick shot. The camera would automatically control the aperture, shutter speed, and so on to achieve the appropriate exposure. In some cases, it would use a flash to fill in the light. - ** Automatic Program Mode (P)**: It is suitable for users who have a certain foundation in photography and want to explore more creative control. In an environment where the lighting conditions did not change much, the camera could manually adjust the USB, white balance, etc. The camera would automatically adjust the aperture and shutter to maintain the correct exposure, and could lock the exposure value or adjust the dimming mode. - ** Aperture priority mode (A or Av)**: When controlling the depth of field is the key, such as portrait photography, macro photography, or when a specific background blurring effect is required. Setting the aperture size manually determines the clear and blurred parts of the picture, and the camera automatically adjust the shutter speed to match, helping to create the desired depth of field effect and control the exposure. - ** Shutter priority mode (S or Tv)**: For shooting dynamic scenes, when you need to control the motion blur effect, such as sports events, wild animals, or water currents. By setting the shutter speed, you can freeze or blur the action, and the camera will automatically adjust the aperture to ensure exposure. - ** Manual mode (M)**: suitable for photography professionals or photographers who have high requirements for camera control. It was used in complex lighting environments, when precise control of exposure was required, or when creating specific visual effects. All parameters, including aperture, shutter speed, and so on, needed to be manually set. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Canon single-lens reflex character photography lens
There were many types of Canon DSLR lenses for character photography. Among them, the 35mm f1.4 lens had excellent performance in portrait shooting. It could capture the delicate expression of the character and show the surrounding environment. The f1.4 large aperture background blurring effect was good, suitable for traveling portraits or indoor portraits. The 85mm f1.2 medium-focus lens could capture the details and expressions of the characters while maintaining a certain distance on the full frame. The picture was natural and realistic. The f1.2 large aperture allowed it to take bright and clear photos in low-light environments. The blurring effect was better than that of the 35mm f1.4 lens. The 70 - 200mm f2.8 telephoto zoom lens had a flexible focal length range, and the background blurring effect was better than the 35mm and 85mm lenses. It was suitable for long-distance shots such as stage portraits, athletes, concerts, etc., but indoor shooting required a large space. The EF100mm F2.8L IS USM lens could be used for macro and portrait shooting. It had double IS optical image stabilization, good sharpness and out-of-focus performance, and ideal autofocus speed for macro shooting. The ESF135mm F2LIS USM lens was a close-up shot of a portrait. It could bring a stronger sense of compression and better blurring effect. The focusing speed was fast, the lens body weighed 750g, and the image quality was excellent when the aperture was fully opened. It was sharp inside the focus and soft outside the focus. The 50mm fixed-focus lens was also commonly used for portrait shooting. The F1.2 lens with a large aperture had a better portrait shooting effect. The 50mm focal length belonged to the standard focal length, and the shooting effect was close to what the human eye could see. It would not cause space compression and could better express the surrounding environment of the subject. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What to practice with in single-lens reflex photography?
The following are some ways to practice with DSLR photography: ** 1. Start by familiarizing yourself with the camera ** 1. ** Basic camera operation parts ** - First, he grasped the way to hold the camera. He wrapped the camera rope around his wrist or neck, held the opening on the right with his right hand, and naturally held the lens under the zoom ring with his left hand. The index finger or middle finger of his right hand was on the shutter button, and his thumb was on the dial to adjust the camera. - He learned how to install the battery and memory card, how to charge the battery and install the battery and memory card, how to turn on the camera (such as turning the top of the camera on), how to use the shutter button (press the focus button halfway, press the camera button after the focus is successful), how to install and replace the lens, how to view the screen, and other basic operations. 2. ** Setting of camera parameters ** - The focus was on mastering the three basic imaging parameters, namely the sensitivity, shutter speed, and aperture. The higher the sensitivity, the brighter the image; the smaller the shutter speed (the faster), the clearer the moving object, but the light will become darker; the smaller the aperture (the larger), the brighter the light, and the larger the aperture can shoot objects with high depth of field. - Try to manually adjust the shutter, white balance, framing, and focus in the manual mode (M gear) to familiarize yourself with the effects of various camera settings on the image. ** 2. Practice from different shooting scenes ** 1. ** Take close-ups of small, still objects (like flowers, birds, insects)** - You can use the Av gear, set the aperture to f5.6 or below, focus at 50 or above, and try to shoot within 1m. This can make the background blur, so you can practice close-up shots of specific subjects and master the creation of the background blur effect. 2. ** Shooting characters ** - Basically, use a larger aperture (within f5.6) and a focal length of 50mm or above. The shooting distance is determined according to the full body, half body, and head shot. The background is blurred. The Av file is used for shooting. Through shooting people, the main body of the character is highlighted and the background is processed. 3. ** Shooting Scenery ** - Using the Av file, choose an aperture above f8, and the focal length can be adjusted according to needs (pay attention to the wide-angle distortion). Practice the aperture selection in landscape photography and how to deal with wide-angle distortion and other problems. 4. ** Shooting Night Scenery ** - Mount the tripod, use Av gear, customize the white balance or incandescent lamp, use an aperture of f8 or above (a small aperture can make the light appear like starlight), use the pre-raised function of the reflective board, cover the viewfinder with the square cover on the strap to prevent stray light from entering, control the IQ to be within 200, and extend the exposure time. Through this method, practice the control of the image quality and reduce interference factors in the night scene shooting. 5. ** Shooting fireworks ** - Use the shutter release and B shutter to shoot fireworks. Try to shoot the effect of overlapping fireworks and master the special shutter skills in shooting fireworks. 6. ** Capture a moving object ** - When the light is good, use the Av gear and adjust the aperture size as appropriate. If you want to shoot a large depth of field, use an aperture above f8, and the opposite for a small depth of field. If you want to shoot a dynamic effect, you can use the Tv gear. The shutter is about 1/30. When you focus, press the shutter and move the lens to chase the subject. This is to practice the shooting skills of dynamic objects. 7. ** Shooting water or fountains ** - Using the Tv gear and a shutter speed of about 1/50, practice shooting a satin-like effect to avoid the situation of intermittent water droplets due to the shutter speed being too fast. 8. ** Portrait at night ** - Get on the tripod, adjust the white balance (automatic or custom), set the USB to 100 - 400, use the Av gear, aperture f8, use the slow sync flash and rear curtain flash mode, and practice the use of the flash and the parameters in the portrait shooting at night. ** 3. Practice from composition ** 1. ** Follow the principles of composition ** - When shooting, follow the composition principles of symmetrical, proportional, diagonal, size, and so on. Practice how to organize the picture. For example, when shooting the classic camera position of Qianhu, shoot from a distance with telephoto. Use the pincushion-shaped distortion of telephoto to compress the space and arrange a person as the visual focus to practice the composition skills in a specific scene. 2. ** Prominent main body ** - Make the photo have a clear and distinct theme. Whether it's a person, still life, or an event, it must be clearly expressed. Focus on the subject, eliminate or compress the elements that can't support the subject and distract attention. Through this method, you can train your grasp of the subject's prominence and the simplicity of the picture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single lens reflex photography, brightness adjustment
There were many ways to adjust the brightness of a single-lens reflex camera: 1. ** Use the camera menu to adjust the display brightness ** - Canon DSLR: Press the [Menus] button on the top left corner of the screen, switch to the menu bar marked with the wrench, find the [LCD Brightness] option, and enter the LCD brightness setting. Change the brightness setting from (Automatic) to (Manual) to adjust the brightness accordingly. - Nikon single-lens reflex: press the MENU key, select the settings menu (shaped like a small wrench), select the brightness of the LCD display, press the down arrow or up arrow to adjust. 2. ** Adjusting exposure compensation ** - In automatic mode, aperture priority, and shutter priority, the exposure compensation button could adjust the darkness or brightness of the photo without changing the shutter and aperture. 3. ** Adjusts sensitivity (USB)** - The camera will automatically set the sensitivity of the Canon Canon Generally speaking, the higher the sensitivity, the more sensitive the camera was to light in a darker environment. The photo might be brighter, but too high sensitivity might cause noise problems. In a dark environment at night, high sensitivity and exposure compensation could be combined. For example, the Nikon D3200 camera could be used to shoot under the constant light. It could be adjusted to around 200, and the aperture and shutter speed could be used to adjust the overall brightness. 4. ** Aperture adjustment ** - The size of the aperture affected the amount of light entering. The smaller the aperture's F value, the larger the aperture. The larger the amount of light entering, the brighter the photo. For example, when the Nikon D3200 camera was shot under the constant light, the aperture could be adjusted to around F6 to adjust the brightness of the picture, and the aperture size could be changed according to the brightness of the picture. 5. ** Shutter Speed ** - The shutter was measured in seconds. The longer the shutter time, the greater the amount of light, and the brighter the photo. For example, when the Nikon D3200 camera was shot under the constant light, the shutter speed could be set to about 1/30S to adjust the brightness, or it could be adjusted according to the actual situation. 6. ** In the picture quality adjustment parameters, adjust the "Brightness" option ** - In natural scenery photography, the "Brightness" option corresponded to the "key value" that controlled the brightness of the middle tone of the picture. By adjusting the "Brightness", the middle tone could be brightened or darkened under the same exposure parameters. For example, when shooting natural scenery, adjusting the "brightness" to-0.5 ~1.5 could obtain different picture effects while maintaining the same exposure. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single lens reflex photography photo size
The size of a DSLR photo was affected by many factors. In terms of image quality settings, it was divided into L, M, S, and other different levels. If it was an 18-million-pel camera, the image size of the L-quality JPGE format was about 6 - 8M, and the M-format was about 3 - 5M. The image size of the Raw-format was about 25M, and the M-quality was about 17M. From a pixel-wise point of view, taking the 24-bit true color without compressing format as an example, one pixel-required 2-bit space. Different numbers of pixel-corresponded to different theoretical image sizes. For example, a 20-million-pixel-by-2644x2644 image compressed into JPG format would have less than 10M space. The higher the resolution, the clearer the image, the larger the overall size, and the richer the details. However, the size of the video file would also be huge. In addition, in a single-lens reflex camera, 1M = 1,000,000 resolution. For example, if 7.7M was used to take a photo with 7,700,000 resolution, it would take up about 2M of capacity. From the photo format, it was divided into JPGE and RAW format. The size of the same quality photos in different format also varied. At the same time, the default photo size ratio of the single-lens reflex camera was 3:2, 4:3, 16:9, 1:1, etc. Whether the photo size was set to the maximum should be determined according to actual needs. For example, when creating photography or advertising (wedding) photography, it should be set to the maximum resolution and use the RAW high-definition format to meet the needs of post-production, adjustment, trimming, printing, etc. For news photography or travel portrait photography, the photo size did not have to be the largest and the JPG format could meet the needs of rapid network transmission and sharing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
