I've been having some trouble dealing with lightning and focusing. I've been wanting to take a picture with only the subject being lighted up, while the background and everything else is engulfed in darkness, but even after playing with metering and the flash, I can't seem to do it.
So would anyone be able to give me a simple setup for lets say, an apple or something, just so I can understand the concept of it?
Also, the same thing with focus, is it possible to have the subject focused very sharply, while everything else (in a circle around the subject) is blur? I know depth of field would work, but wouldn't it only if theres distance between all the elements of the picture?
