What basic knowledge do you need to learn photography?
If you want to learn photography, you need to master the following basic knowledge: - ** About exposure ** - ** Shutter **: The shutter is a device that controls the exposure time, measured in seconds. When the other parameters were unchanged, the higher the shutter speed, the longer the light entry time, the more exposure, and the brighter the picture; otherwise, the darker the picture. - ** Aperture **: Aperture size affects the amount of light entering and depth of field. The larger the aperture value, the smaller the aperture, the less light and the depth of the field; Conversely, the larger the aperture, the more light and the depth of field. The depth of field was simply the distance before and after the object was clearly photographed. If the depth of field was small, other objects except the main body would be blurred, and if the depth of field was large, other objects would be clear. - ** Iso-sensitivity **: The higher the sensitivity, the lower the shutter speed required to obtain the same exposure effect, and the brighter the photo. However, the higher the sensitivity, the quality of the photo may be reduced and graininess may appear. When there was sufficient light, the sensitivity was generally around 100. In M manual mode, if the screen was still dark after adjusting the aperture and shutter and setting the sensitivity to 100, the sensitivity could be increased appropriately, but it should not exceed 3200. Aperture, shutter, and USB were all related to each other, so they needed to be adjusted during shooting. - [** exposure mode **: There are five main types.] The shutter speed and aperture are automatically calculated by the camera in the automatic mode (Automatic) and cannot be changed during shooting. The programmed automatic exposure mode (P) allows the camera to automatically calculate the shutter and aperture combination, and the photographer can change the parameters. The shutter priority mode (S or TV) keeps the set shutter speed unchanged, and the camera will automatically calculate the aperture size. The aperture priority mode (A or LV) keeps the aperture size unchanged, and the camera will calculate the shutter speed. It is suitable for shooting portraits to maintain a large aperture. The full manual (M) shutter and aperture were set by the photographer himself, and the photographer was required to be familiar with the combination of the two. - ** Focus ** - Manual Focus (MV): It is suitable for close-up shooting. It is a more accurate focusing method. - ** autofocus **: AF-S single-shot autofocus can be used for portrait, still life, and architectural shooting. When you press the shutter halfway, you can press the shutter when you hear "beep", which means that the focus is successful. AF-C continuous focus can be used for moving objects, capturing people and animals, and when you press the shutter halfway, you can continue to focus. AF-A intelligent (camera) autofocus can automatically determine whether to use single-shot or continuous focus according to the subject, but it is easy to make mistakes and cause out-of-focus. - ** White Balance **: First, correct the color temperature and restore the color of the subject, so that the color of the shot under different light sources is similar to that of the human eye. Second, control the color temperature to adjust the overall color atmosphere. - ** Knowledge of composition **: A reasonable composition can improve the quality of a photo, such as using the background to block, stagger the composition, create a picture-in-picture effect, and show the layering of the picture. - ** Shooting Techniques (For Video Shooting)**: Basic shooting techniques such as pushing the camera, pulling the camera, and surrounding the camera will help you shoot a more attractive video.

Basic photography knowledge
Here are some basic photography knowledge: 1. ** Equipment selection **: If you just want to experience photography, a portable camera can satisfy your needs. If you want to learn photography in depth, you can use a mobile phone or portable camera to learn composition, lighting, and post-color adjustment skills. After you have some experience, you can buy a professional camera. 2. [Familiar with the equipment: The camera manual is a good helper for understanding the operation of the camera. Many basic operating knowledge is introduced in detail in the manual.] 3. [Find the subject: Don't think that beautiful scenery is only in the distance. Pay attention to the details around you and be good at discovering the shooting materials around you.] 4. [Focus on practice: No matter how many photography works and tutorial you read, it's not as rewarding as going out and taking real shots.] 5. ** Imitate excellent works **: By imitating the composition and lighting techniques of excellent photography works, you can effectively improve your photography skills. 6. ** Master Shooting Techniques ** - ** Stabilizing Equipment **: Hold the phone or camera firmly with both hands to avoid blurring the picture due to shaking during the shooting process. - ** Precise Focus **: Use autofocus first. When there is insufficient light, you can focus manually. Focus on the subject. - ** Pay attention to the details of the character shooting **: Pay attention to the expression and posture of the character when shooting the character, ensure the integrity of the character's image (control the half body, whole body, and close-up), avoid cutting the key points of the character (such as the neck, knees, ankles, fingers, etc.), and pay attention to not placing sharp objects on the head of the character or crossing the neck. - ** Control the exposure **: Make sure the image exposure is accurate. It can't be too dark or too bright. The phone will usually adjust automatically. - ** Maintain Level **: When shooting objects such as buildings, pay attention to maintaining the horizontal line horizontally and vertically (except for special wide-angle distortion effects). - ** Balance the main body of the picture **: You can use the nine-square grid composition, the middle composition, and other methods to place the focus of the shooting on the three-point line or the four focal points of the nine-square grid, or place the main body in the middle position to avoid the main body being in the corner. - ** Keep the image simple **: Remove unnecessary items from the image to make it simple and clean. - ** Choose a suitable angle **: Try shooting from a variety of angles, such as up, down, squatting, and lying down. Don't just shoot from a standing position. - ** Depth-of-field effect **: Make good use of the depth of field function of the phone to highlight the main body of the picture and blur the messy picture through the small depth of field. - ** Using white space technique **: avoid too many elements entering the picture, adhere to the principle of minimalism, use white space to make the picture clean and tidy, and highlight the subject. - ** Use line composition **: Find the lines of the object to be photographed, and use cross-composition, parallel composition, and other methods to take an orderly and regular picture. - ** Use frame composition **: Place the character in the frame of a door or window, and guide the line of sight into the frame to highlight the main body. - [Use Light]: Learn how to use light such as backlighting, fairing, and silhouette. 7. ** Post-processing **: Simple computer post-processing such as color matching and cutting can help to improve the quality of the work, but it cannot be overdone. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Basic knowledge of photography
Lectures on basic photography usually covered many aspects. In terms of cameras, it would involve the classification of cameras. For example, according to the framing method, it could be divided into single-lens head-up framing (CP) cameras and single-lens reflex (TF) cameras; according to the film size, it could be divided into 135 cameras, 120 cameras, etc. It also explained the characteristics of different types of cameras, such as film cameras and digital cameras. Film cameras recorded images using the properties of the silver Halide that turned black when it came into contact with light, while digital cameras were different from film cameras. Regarding photography techniques, the concept of depth of field was mentioned, including large depth of field (the subject and background are clear, often used for group photos, meetings, events, landscape photography, etc.), small depth of field (only a part of the picture is clearly shown, the rest is blurred, often used for portrait photography), and soft focus (no part of the picture is 100% clear, often used for shooting beautiful women). It would also include knowledge of light usage and composition techniques. For example, in composition, one had to use various scenes and perspectives to search and shoot in all directions. In terms of light usage, one had to understand the most essential modeling elements of photography--light and shadow, so that the two-dimensional photos would have a three-dimensional sense. In addition, the lecture might also talk about the history of photography, the basics of art, and encourage participants to use creative thinking to try different styles of photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The unit carries out basic photography knowledge training
The following is a basic framework for the unit to carry out basic photography knowledge training: ** I. Training content ** 1. ** Three Elements of Photographic Exposures ** - Aperture: A mechanical device that controls the amount of light that enters the camera lens. By changing the size of the opening to adjust the amount of light entering, the larger the opening, the more light entering, and the stronger the background blurring effect; the smaller the opening, the less light entering, and the greater the depth of field of the picture. - ** Shutter **: A device that controls the exposure time of the camera's light-sensitive element. The shutter speed was fast, the sensor was exposed to light for a short time, and the amount of light entering was small. The photo was dark, suitable for shooting moving objects. The shutter speed was slow, the sensor was exposed for a long time, and the amount of light entering was large. The photo was brighter, which could be used to shoot night scenes or express the movement trajectory of objects. - ** Light sensitivity (USB)**: indicates the sensitivity of the camera sensor to light. The higher the value, the more sensitive it was to light. Images could be captured in dark environments, but it would increase noise and reduce image quality. The lower the value, the less noise and better image quality, but more light was needed for correct exposure. 2. ** Depth-of-field related knowledge ** - The factors that affected the depth of field included aperture, focal length, and shooting distance.(The adjustment of a large frame camera also affected the depth of field.) Large depth of field (small aperture + short focal length lens is commonly used, but pay attention to shutter speed and image distortion) can clearly show a large range of scenes from near to far, which is conducive to describing the shooting environment, explaining the position of the subject and reflecting the perspective relationship of the scene; Small depth of field can highlight the subject and blur the background. - The depth of field feature could be used in combination with perspective methods to create a sense of depth in the photo. For example, it could be achieved by distinguishing between the real and virtual of the front, middle, and distant scenes. 3. ** Method of composition ** - For example, the nine-square grid composition could use the golden cutting point to determine the shooting angle of the work, helping the photographer find the focus and balance of the picture, making the photo more beautiful and attractive. 4. ** Color and aesthetics ** - The use of color in photography: Different colors can convey different emotions. For example, the blue background is clean and high-grade, orange and blue have a contrast of cold and warm; red is warm and eye-catching, and red and green are also very high-grade. - The dimensions of reading photography included composition, light and shadow, color, clothing, movements, the photographer's thoughts, expression, and so on. He could improve his aesthetic ability by studying excellent works (such as reading books such as "The History of the World's Photographer", reading magazines such as "VOGUE", admiring movies such as "Out of Africa", and observing famous paintings in the world), and then apply it to his own photography creation. 5. ** Basic operations and functions of the camera ** - For the cameras or mobile phones that employees may use (considering the high frequency of modern mobile phone shooting), they will explain functions such as highlight prompts, exposure compensation, white balance settings, focus mode and focus settings, memory card selection, and recording methods. ** 2. Training Method ** 1. ** Theory explanation ** - Professional photography teachers or experienced staff in the unit will systematically explain the basic knowledge of photography in an easy-to-understand language. 2. ** Instance demonstration ** - Combining the actual photos or live shooting demonstration, it directly showed the influence of aperture, shutter, sensitivity and other factors on the photo effect, as well as the effect of different composition methods and color matching. 3. ** Question and Answer ** - Give employees the opportunity to ask questions and answer their questions during the photography process, such as adjusting camera parameters and shooting techniques for specific scenes. 4. ** Practicing Operation ** - Arrange a certain amount of time for employees to practice shooting and consolidate their knowledge in practice. For example, shoot in a suitable scene within or near the unit, and be guided by the trainer on the spot. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
