How to use a SLR camera

Your question is really a bit big, and the instruction manual is really the best photography textbook. Here I can only briefly tell you the process of learning to use SLR:

1. Learn to use P file (it is a random aperture shutter combination of the camera, and a combination will appear every time the shutter is pressed half). You will find the changes of various combinations through shooting, and then manually adjust the combinations (AV file, TV file, M file).

2. Learn to use AV files (aperture first), that is, you decide the aperture value, and the camera will automatically get the shutter speed according to your aperture value. AV files are suitable for shooting static subjects, generally accounting for 80% of ordinary shooting. Here you should remember: large aperture and small depth of field (usually called blur) are often used to take portraits. Small aperture and large depth of field, each point of the picture is clear and sharp, suitable for scenery.

3. Learn to use the TV file (shutter priority). The operation is the opposite of the 2 process, which is suitable for moving objects.

4. Mastering the basics and learning composition is another big topic, haha.

5. Learn to incorporate personal elements into the picture, that is, the personality of the photo.
