Simple technical questions...
Jun 21, 2012


If am standing before a 2 mile long lake before dawn (i.e. very low light) and focus at infinity with a wide angle lens, what happens to the depth of field if I use a large aperture (say f/4.0) vs a small aperture (f/16.0)?

The reason? To minimize the use of high ISO (> 400) and very long shutter speeds (> 30 seconds) in very low-light conditions.


With a 90mm macro lens and the same aperture (say f/32), will I increase my depth of field if I move further away from the subject?

Reasons: Sometimes I try to maximize depth of field with a particular shot, and larger apertures only work up to a point.
