I am a fan of photography enthusiasts, but as a novice, is there any way to master SLR cameras quickly?

I didn't understand the first half of the sentence. Are you a photographer or not? Or "a fan of a photographer"? Hehe, but this does not affect the following questions.

There are three suggestions for beginners to master SLR quickly:

1, take an hour to read your instructions and read them clearly, so there are not many problems in the use of the machine.

2. Search for "shutter aperture sensitivity" on the Internet and find a post to study the relationship between them. I don't think it will take two hours.

3, but also on the Internet search "composition", a simple understanding of what are the simple composition methods. It will take about 2 hours.

At this point, in less than five hours an afternoon, we can basically shoot.
