photography skills and camera parameters
Here are some photography techniques and camera settings:
** 1. Photographic Skills **
1. ** Light utilization **
- When shooting, one had to wait for the right light to alternate between light and dark. The light in the morning and evening was soft and the color in the evening was warm, which was a better time to shoot.
- Using contrast to enhance the effects of the image, such as color, light and shade, shape contrast, such as the red apple in the green grass, the color contrast between the red house in the distance and the surrounding environment, and the use of light and shade contrast, color and size contrast, etc.
- To create momentum, one could rely on the layering of scenery, looking for layers of scenery such as mountains, dense forests, etc., and could also use different angles and heights to shoot. It was easy to encounter such scenes before the rain in the grassland. One could use the mobile phone to shoot from a distance and increase the mb value to make the distant light more beautiful and warm.
- Choosing a suitable prospect could increase the interest and visual impact of the picture. For example, adding waves and reefs when shooting the sea, adding leaves in front of buildings, and adding a sunflower in the sea of sunflowers as the prospect.
- When shooting silhouettes, the main body should have gaps, and the background choice was very important.
2. ** Shooting Mode Selection **
- You can choose automatic mode or P mode for daily photos, daily life and travel records, etc.
- For portraits, scenery, still life close-ups, and other subjects that require depth of field, it is recommended to use aperture priority mode.
- For shooting sports, such as sports, slow door shooting, etc., it is recommended to use shutter priority mode.
- In complex shooting environments, you can choose the manual exposure mode if you want to have a sense of operation.
3. ** White Balance Setting **
- Generally, setting it to "Automatic White Balance (AWB)" could basically restore the true color of the environment. If you want to adjust the environment atmosphere, you can adjust the color temperature parameters later.
4. ** Photometering settings **
- Most of the time, you can choose to evaluate the measurement (matrix measurement, average measurement) to meet most scenes. You can also choose the center focus average measurement (the measurement area is about 1/3 of the middle of the picture) or spot measurement (about 3% - 5% of the picture).
5. ** Focus setting **
- Single-point autofocus AF-S: Focus once by pressing the shutter halfway, suitable for still life shots.
- Servo-autofocus AF-C: suitable for shooting moving subjects. Half-press the shutter to maintain tracking focus for capturing.
- Smart autofocus AF-A: automatically chooses AF-S or AF-C according to the movement of the subject.
- Manual Focus: Manual adjustment of the focus ring when the autofocus is unusable or an error occurs.
6. ** Setting of exposure compensation **
- In automatic mode, aperture priority, shutter priority, and other modes, the brightness of the photo was maintained at 0EV, the exposure compensation was increased when it was dark, and the exposure compensation was reduced when it was bright.
7. ** Picture format settings **

Landscape photography camera parameters
In landscape photography, the settings of the camera parameters were crucial. ** 1. Aperture ** 1. [Function and Principle] - The aperture controlled the clear range of the camera's image and the amount of light entering. Because landscape photography was mostly shot for large scenes, it required a large clear range, so a small aperture was usually chosen. Generally, F11 - F13 was the optimal aperture value for shooting scenery. The small aperture could increase the depth of field, allowing the image to remain clear from near to far, enhancing the spatial sense of the image. For example, when taking pictures of mountains and rivers with a level of near and far scenery, a small aperture could clearly show the mountains in the distance and the water in the vicinity. 2. ** Special circumstances ** - When shooting water scenes, a small aperture can make the ripple effect more obvious. ** 2. Shutter ** 1. ** Relationship with Aperture and Isos ** - Shrinking the aperture would reduce the amount of light entering the camera, which required adjusting the shutter speed. If it was a hand-held shot, pay attention to the safety shutter setting to prevent the picture from blurring due to hand shaking. However, if a tripod was used to shoot steadily, the shutter speed setting could be more flexible. 2. ** Exemplary parameters ** - The shutter speed varied in different scenes. For example, when shooting at night, the shutter speed might be 10s-20s; when there was sufficient light during the day, the shutter speed might reach 1/250s or even higher, such as 1/2640s, depending on the lighting conditions, aperture size, and the desired shooting effect. ** 3. Iso-level ** 1. ** Impact on Image Quality ** - When shooting scenery, try to set the USB to the lowest value to ensure the highest quality. A high IQ might cause noise to appear on the screen and affect the purity of the image. ** 4. Focus Point ** - For scenery subjects that did not have a clear subject in the picture, the focus point could be set to 1/3 of the near picture, which was the horizontal line below the screen. ** 5. White Balance ** 1. ** Automatic White Balance ** - If you don't want to have a clear color tone when shooting, the camera's white balance color temperature can be set to automatic. 2. ** White Balance ** - If you want to set the white balance according to the color tone style, you can use the white balance drift to achieve the best color tone effect. For example, when shooting in the setting sun, using the shadow white balance mode could make the picture appear warm and comfortable, and when shooting in the early morning, using a higher color temperature than the actual color temperature could get a cool blue picture. When shooting in the warm evening, you can set the white balance to shadow mode, and when shooting in the cold morning, you can set the white balance to incandescent mode to enhance the blue image effect. ** 6. Compensation for exposure ** 1. ** Dark the image ** - When the clouds in the sky were shown and the ground scene was included in the image, in order to reduce the brightness difference of the image, the exposure compensation could be reduced after aiming at the water surface to measure the light, so that the brightness of the image would be reduced, making the clouds in the sky more layered. 2. ** Illuminate the image ** - It was often necessary to increase exposure compensation when shooting snow scenes, and in foggy weather, exposure compensation should also be increased to prevent the image from turning gray. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera parameters for lake photography
The following are some of the camera parameters for lake photography: - If you want to shoot a sparkling effect, you can try to use the smallest aperture (usually less than 10) with the shutter speed to check the shooting effect. The shutter speed can be set to 1/250 seconds, the aperture is generally set to the smallest, and the shutter can be adjusted according to the brightness of the scene. - [Effect of shooting silky water surface: Aperture priority mode can be used for exposure mode (audio file), aperture F8, shutter speed 1/200s, iso100.] - Shooting the starlight effect on the water surface: Choose backlighting to shoot. It's easier to capture the sparkling and starry water surface at sunset and sunrise around 3 - 5 pm. The aperture is adjusted to F8 - F13.(For example, the shooting parameters refer to the A-V file, aperture F12, shutter 1/200s, iso100). When shooting with a small aperture, there will be a cross star. When shooting, you can use a hood to avoid glare. If you don't have a hood, you can use cardboard to cover it. There are also examples of shooting parameters such as 5 - 6 pm aperture F32, shutter 1/400s, iso100, focal length 110mm or 10:00 in the morning aperture F20, iso400, shutter speed 1/160s. In addition, when shooting the sparkling lake surface, the camera parameters could also use the aperture between F8 - 16 according to the changes in the environment. However, if the aperture was too large, it was easy to cause the situation of out-of-focus. If the aperture was too small, the image quality would be affected. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon camera indoor photography parameters setting
The following are some suggestions for Canon's indoor camera parameters: 1. White Balance: - If you want a warm color picture, you can set the white balance K value to a higher value, such as K5500 (to create a warm cinematic style), and adjust the white balance offset as needed (such as A3G4). If you want a cool color picture, you can set the K value to a lower value, such as K4200 (cool emotional style). 2. ** Picture Style **: - When shooting a portrait, you can choose the style of the portrait photo. The parameters such as intensity, precision, saturation, threshold, contrast, and tone can be adjusted according to the desired effect. For example, intensity +5, precision +4, saturation +2, threshold +4, contrast-3, tone 0 (portrait settings in a warm cinematic style). 3. <strong>**</strong></strong></strong> - If the room is dark, in order to get enough exposure, you need to increase the IQ appropriately, but be aware that an overly high IQ will introduce noise. If the high-tolerance mode was activated, the range might jump to 800. 4. ** Shutter Speed **: - If you were shooting a static scene such as an indoor still life or portrait, a slower shutter speed could make the photo softer and capture more details and colors. If you were shooting a subject that might have slight movements, you should increase the shutter speed appropriately to prevent blurring. 5. ** Aperture **: - The aperture size was adjusted according to the desired depth of field effect. A large aperture (such as f/1.2, f/1.4, etc.) could blur the background and highlight the main body, suitable for shooting portraits; a small aperture could make the entire picture clear, suitable for shooting indoor environments. 6. ** Shooting Mode **: - You can choose the shooting mode according to the actual situation. For example, the aperture priority mode, first determine the aperture size to control the depth of field, and the camera will automatically match the shutter speed and the CPU. If there are special requirements for the shutter speed (such as shooting indoor sports scenes), you can choose the shutter priority mode. If you are experienced, you can also use the manual mode to precisely control the various parameters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The expression of the camera shooting parameters for photography works
The camera's shooting parameters mainly included light sensitivity, shutter speed, aperture, exposure compensation, focal length, and light measurement mode. 1. ** Light sensitivity (USB)**: This is used to indicate the sensitivity of the camera sensor to light. It is usually expressed in numerical form, such as USB: 320. The higher the value, the more sensitive the sensor was to light. In a darker environment, the brightness of the image could be increased by increasing the USB value, but too high a value might introduce noise. 2. ** Shutter Speed (S)**: The exposure time, measured in seconds. For example, S: 1/500s. The shutter speed affected the brightness of the photo. The longer the exposure time, the brighter the photo. High-speed shutter (such as 1/500 seconds) can capture the instantaneous posture of high-speed moving objects. Slow shutter (such as 4 seconds) can be used for special effects creation. 3. ** Aperture (F)**: Expressed in F/x (or Fx)(x is the aperture value), which can be understood as a fraction. The smaller the x value, the larger the aperture, the more light entering, the brighter the picture and the smaller the depth of field. The focus subject was clear while the background and the background were blurred, suitable for close-up subjects. The larger the x value, the smaller the aperture, the less light entering, the darker the picture but the larger the depth of field, suitable for scenery, group photos, etc. F: 1.8. 4. ** exposure compensation (EV)**: Expressed in the form of a numerical value, such as EV: 2.3. It is used to adjust the result of the camera's automatic exposure to make the photo brighter (positive compensation) or darker (negative compensation). 5. ** focal length **: In millimeters (mm), for example, focal length: 53mm, which determines the angle of view and magnification. 6. ** Metering mode **: Commonly used are matrix meters. Different modes will affect the camera's measurement of light and exposure calculation. In addition, for mobile photography, there were also parameters such as resolution and frame rate. The resolution of 1080 was used to indicate the clarity of the picture, and the frame rate was 30 frames or 60 frames. 30 frames was suitable for shooting still pictures, and 60 frames was suitable for shooting moving pictures to ensure the smoothness of the video. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to set the parameters for the photography mode of the zoom camera
Baidu photography bar car show camera parameters
The following are some suggestions for setting the camera parameters during the auto show: ##1. Choice of camera lens You can prepare a wide-angle, large-aperture, fixed-focus lens (such as 35mm f1.2) for shooting large scenes, and a 70 - 20mm f2.8 medium-length zoom lens for close-ups. ##2. Shooting parameters 1. ** exposure mode **: Usually, the aperture priority mode is selected to better control the depth of field. For wide-angle shots, you could choose a smaller aperture, while for close-ups of models, you could use a large aperture (f2.8 - 5.6). 2. ** Light sensitivity (USB)**: You can choose between 100 - 1600. If you use a flash with a soft mask, the sensitivity can be set to 100, so that the light on the model's face will not be very bright and hard. If you don't use a flash, you should increase the sensitivity. For better cameras, especially professional cameras, the image quality will not be affected too much when the USB is up to 2000 - 2500. 3. [White Balance: The lighting at the auto show is complicated. There are all kinds of light sources with different color temperatures.] Professional cameras can choose automatic white balance, non-professional single-lens reflex cameras or digital cameras are best to use manual white balance. 4. ** Metering mode **: Due to the complex lighting of the scene, there are top light, side light, backlighting, etc., the camera's first choice for measuring light is to use spot measurement. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon Micro-camera photography skills
Here are some photography tips for Canon's micro-camera: ** 1. Basic operations ** 1. ** Installment and boot ** - First, he installed the memory card and lens, then turned on the top of the camera. 2. ** Shutter Operation ** - Press the shutter button halfway to focus. After focusing, press the shutter button to shoot. The shutter was used to control the amount of time the light entered the camera. The longer the shutter was set, the longer the light entered the camera and the higher the brightness. On the contrary, the shorter the shutter was set, the shorter the light entered the camera and the lower the brightness. When setting the shutter speed, it must be higher than the safety shutter speed to protect the camera. 3. ** Manipulation of the camera ** - The lens can be changed according to the needs. For example, when Canon R5 is connected to the RFIS lens, the IS switch on the lens is the anti-shake switch, and the body and the lens are connected to the anti-shake switch (the menu is not displayed). When connecting the original EP anti-shake lens, the body and the lens cannot be connected to the anti-shake switch, and the menu is not displayed. The body anti-shake does not work, and only the lens IS works. ** 2. Shooting parameters setting ** 1. ** Aperture adjustment ** - The size of the aperture was inverse to the amount of light entering the camera. The smaller the aperture, the brighter the picture. When shooting people or still life, you can adjust the aperture to make the photo clearer. When shooting scenery, you can adjust the aperture to the middle position to avoid exposure when the outdoor brightness is high. 2. ** Automatic Focus and Manual Focus ** - Canon's micro-camera had both autofocus and manual focus functions. Basically, all scenes could be used with autofocus, but in environments such as shooting through objects or in low light, the quality of the image would be clearer with manual focus. 3. ** Color temperature setting ** - The color temperature determined the style of the entire picture. If you want to take a picture with warm colors, you should increase the color temperature. If you want the picture to be cool, you should lower the color temperature. 4. ** Compensation for exposure control ** - The manual exposure compensation can be adjusted in 1/2 or 1/3 steps between the levels of +/-3, and the automatic bracketing can also be adjusted in 1/2 or 1/3 steps between the levels of +/-3 (can be combined with manual exposure compensation). 5. ** Metering Method ** - The manual dimmer was adjusted in 1/2 or 1/3 steps between the levels of +/-3, and the automatic bracketing was also adjusted in 1/2 or 1/3 steps between the levels of +/-3. For still images, there was evaluation dimming (linked to all auto-focus points), partial dimming (about 6.1% of the screen), spot dimming (about 3.1% of the screen), and center-focused average dimming. For short films, the image sensor was used for center-focused average dimming and evaluation dimming. - White balance has automatic (ambience priority), automatic (white priority), default (sunlight, shadow, cloudy, tungsten light, white fluorescent light, flash), user defined, color temperature (about 2500 - 10000K) and other modes. It also has white balance correction and white balance bracketing functions. ** 3. Special shooting ** 1. ** Shooting characters ** - According to the surrounding environment, the aperture value was designed. Generally, the aperture was adjusted to make the photo clearer. 2. ** Shooting Scenery ** - You can adjust the aperture to the middle position and adjust the shutter value to a safe value to avoid exposure. 3. ** Shooting the Moon (Special Scene example)** - Set the camera mode to M (manual exposure), set the shutter to 1/15s, set the USB sensitivity to 100 on the screen, pull the lens to the longest angle, and aim it at the subject. When the screen's focus frame shows green when the shutter is pressed halfway, it means that the focus is accurate. At this time, you can press the shutter. ** 4. Depth of Field ** 1. ** Great depth of field ** - When the subject and background are clearly displayed, it is a large depth of field. It is often used for group photos, meetings, events, landscape photography, etc. It can clearly show the subjects at different distances, reflect the important details of the picture, and provide more visual information to the viewer. 2. ** Small depth of field ** - Only a part of the image was shown clearly, and the rest was in a soft and blurred state. The blurred part could be used as a background and was often used to shoot portraits to highlight the subject and hint at the emotional state of the character. 3. ** Soft Focus ** - No part of the picture was 100% clear. It could be used to filter the lens. In some cases, it could be used to pull the lens with stockings. It was often used to shoot beautiful women to enhance the beauty and reflect the dreamy atmosphere. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The parameters of the camera
There were many parameters for the camera lens. The following were some common parameters: 1. ** Focus **: It determines the degree of zooming of the lens. A longer focal length was used for long-distance shooting. For example, a telephoto lens could be used to shoot long-distance topics such as sports competitions, wild animals, aircraft, etc., and it could also enhance the background blurring effect. A shorter focal length was used for wide-angle shooting, such as wide-angle lenses for landscape photography, architectural photography, and crowded indoor spaces. 2. ** Aperture **: For example, the main camera of the Vivo X200 Pro is equipped with a large aperture of f/1.57, which helps to take brighter and clearer photos in dark environments. Its periscope telephoto lens has an aperture of f/2.67, which can ensure the clarity and details of the picture when shooting telephoto. The size of the aperture affected the amount of light entering, depth of field, and so on. 3. ** Pieces **: It is one of the important indicators to measure the quality of the camera. For example, the main camera of the Vivo X200 Pro is expected to use a 50-million-pel large sensor, and the periscope telephoto lens is equipped with a 200-million-pel periscope telephoto lens. 4. ** Photosensor **: For example, the sensor of the HD - 3000 camera is a LCD; the main camera of the Vivo X200 Pro has a 1/1.28-inch sensor, and the periscope telephoto lens has a 1/1.4-inch base. 5. ** View angle **: For example, the helmet camera lens is a 3.7mm pinhole lens with a 90-degree view angle. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
External parameters of the camera
The external parameters of the camera were parameters in the world coordinate system, mainly referring to the rotation and translation matrix between the camera systems, such as the position and rotation direction of the camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the camera parameters?
The camera's parameters were divided into two parts: 1. * * Internal reference: - focal length (fx, fy, generally equal): It is related to the optical characteristics of the camera lens and affects the zooming in or out of the image. - Coordinates of the principal point (x0, y0, relative to the imaging plane): In the ideal case, the optical axis of the lens passes through the middle of the image, but in reality, there is an error due to the installation accuracy. This is used to describe this error. - Axis tilt (s, 0 in the ideal case): A variable that reflects the difference between the camera's x-direction and y-direction size reduction ratio. It can convert the length measured by the number of pixels into the length measured by other units in three-dimensional space. It can also indicate the difference between the x-direction and y-direction scale transformation. - Distortion parameters (including the distortion of the radius and the direction of the cut): This is used to describe the distortion effect produced when the lens maps a three-dimensional space straight line onto the image. Under ideal circumstances, the lens should map the straight line into a straight line, but there is actually a deviation. 2. * * External reference **: - Rotation Matrix: It is used to describe the direction of the coordinate axis of the world coordinate system relative to the camera coordinate axis. It is used to determine how the world coordinate point will rotate and fall on the camera coordinate point. - Translational Matrix: It described the position of the origin of space in the camera coordinate system, which was the relevant parameters of the world coordinate point after translation to the camera coordinate point. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
