Learning photography is a very useful study plan.
Three elements of exposure:
① Aperture:
The larger the f value of the aperture, the less the amount of light entering, the smaller the aperture and the less the background blur; The smaller the f value of the aperture, the more light enters, and the larger the aperture, the better the blur of the back system.
② Shutter:
The larger the aperture s value, the more light enters, the smaller the aperture and the slower the speed; The smaller the aperture s value, the less the amount of light entering, and the larger the aperture, the faster the speed.
③ Sensitivity:
The higher the ISO sensitivity value, the more light enters, the brighter the photo, and the worse the image quality. The lower the ISO sensitivity value, the less light entering, the darker the photo, and the better the image quality.
First, the camera interface parameters:
① Automatic gear: scene automatic mode;
② Automatic mode of P file program;
③ TV files: shutter priority mode;
④ AV file: aperture priority mode;
⑤ M gear: manual mode;
6.SCN: special scene;
⑦ CA: creative automatic mode;
⑧ Door B: The opening time of the shutter can be controlled manually.
Second, commonly used exposure value:
(1) When the shutter takes precedence:
Daily shooting:180s ~1/200s;
Grab a car: 1/2000 or more;
Pat baby/pet: greater than V200s;;
Idolization/athletes:11000s or more;
Fireworks shooting: 3s~5s to 5 s (with tripod) to capture people larger than1125 s;
Orbit: > 2 hours (tripod);
Light painting: 15s~30s.
(2) Aperture priority:
Static characters: f1.2 ~ 4;
Close-up of flowers: f1.2 ~ 4;
Portrait at night: F2.8 ~ 5.6;;
Arrest people: f5.6 ~ f11;
Food/Still Life: F8 ~11;
Fireworks/light painting/star track: f11-20;
Starry sky: f1.4 ~ 5.6;
Landscape photo: FB~ 1 1.
(3) Manual M gear:
Take pictures, shutter1125s, aperture F2.8, sensitivity ISO 100 (clear);
Shooting scenery, shutter1125s, aperture 4, sensitivity ISO 100 (sunny day);
Shooting night scene, shutter115s, aperture 18, sensitivity ISO200;; ;
Shooting action, shutter 1/500s, aperture 2.4, sensitivity ISO 100.
Focus mode:
1. Single autofocus:
A single autofocus is generally represented by AF-S, and a "click" sound is heard after half pressing the shutter, indicating that the focus is completed. You can shoot by pressing the shutter, which is generally suitable for shooting still life. For example, commodity shooting, flower shooting, posing for people and so on.
2. Intelligent autofocus:
Is the camera autofocus, represented by AF-A, according to whether the subject is moving or not, it is sometimes wrong to choose single focus or continuous focus.
3. Manual focusing:
Manual focusing is expressed by MF, which is the most accurate focusing method. When autofocus fails, for example, the shooting distance is too close and there is an object blocking, it is necessary to manually focus to adjust. There are also details that the subject needs to pay attention to, such as macro shooting, which needs to be manually focused.
4. Servo (continuous) autofocus:
Servo focusing, also known as continuous focusing, is represented by AF-C. When shooting a moving subject, you can continue to focus until the shooting is over without pressing the shutter again, which is suitable for shooting moving subjects, such as sports and animals.
Photometric determination:
(1) Evaluation of photometry is the smartest:
Evaluation photometry is the average measurement of light in the picture, and it is the most intelligent. However, it is not suitable for scenes with large illumination ratio, which will lead to deviation of measurement results, such as large areas of light or dark.
② Spot metering is the most accurate:
Spot metering measures 3% of the screen area. When the subject is not in the center, it is the most accurate method to directly measure the light at the subject to ensure the accuracy of the exposure of the subject. Combined with the point measurement linkage function, it is the most perfect shooting method. Otherwise, you can only lock the exposure after metering and then make composition and focus shooting.
③ Central key photometry is the most commonly used:
Center-focused photometry is to measure the face position around 1/3 in the center of the picture. When shooting, the subject is usually placed in the center to ensure the correct exposure of the subject. At the same time, the influence of the area outside the rabbit center on the exposure results can be avoided.
White balance: White balance (K) controls the color of the picture and affects the color temperature of the photo.
How to adjust the value of white balance?
When the value of k is >: at 5000K, the color of the scene presents a reddish effect, which belongs to warm tone and has a warm and stable atmosphere effect. Suitable for shooting indoor effect portraits.
When the K value is 4000-5000k, it belongs to the effect of normal middle tone and white tone, and it is really an environmental effect. Suitable for shooting outdoor scenes with good light, portraits/styles.
