Having learned this year that I have ADD,(explains a lot about my life), I thought you meant hyperfocus as in concentrating on one subject to the exclusion of all else.
Silly to think so on a photo forums site but that's part of the condition too.

I know about hyper-focus photographically speaking but don't really use it. I just figure out what I want in focus and what the best dof will be that I can get and go from there.
Maybe I'd be better off if I did think about it. I know some of our experts do.
