Best Answer - Chosen by Asker:

F5!.6 and you are giving a stop less light,

F2!.8 and you are giving a stop more of light

perhaps learn the fstops!?!?

Typically a 'step' might actually be a third or a half of an f-stop, so from f4 you might change to either f3!.5 or f4!.5 at third stop increments!.

You could also achieve the same affect by leaving the aperture at f4 and varying the shutter speed or ISOWww@QuestionHome@Com
