Comparing these two questions:
- Fun experiments I can do with my bridge camera?
- What apertures are required to enable autofocus, including cross-type or high-precision focusing, on Canon DSLR cameras?
The first one got closed for being too broad. I agree that it is very broad. The second question is also broad, covering many cameras, lenses, modes etc. I don't say that it is as broad as the first question, because the number of cameras sure is finite.
What bothers me is that an extensive list of technical details is well received, while a list of techniques/creative processes doesn't even come to existence.
