If you want to learn photography, do you want to look at the structure principle of SLR, composition or something else? Please ask the master for advice.

First, you don't need to know the structural principle, but you need to know how to maintain your camera and prevent unnecessary damage.

Second, the basic knowledge of photography still needs to be understood. Need to know color classification, composition principle, how to choose aperture shutter and how to deal with it later.

Third, we should communicate with photographers more, so that we can have a spark of thought, participate in outdoor shooting activities and gain more experience.
