Macro & Close-up Photography Tips – Focusing

with 2 comments

Focusing for macro and close-up photography is usually best done manually. At close-focus distances lenses can sometimes find it hard to lock focus. If a lens racks the focus out to infinity and then back again before it finally focuses on the subject, this can take some time. It may not even be able to find focus on the subject, and leave you with an unfocused image in the viewfinder.

Macro & Close-up Photography Tips – Aperture, DoF, Diffraction

When you take a photo of a landscape, it's not too difficult to get everything from a few feet in front of you all the way to the horizon in focus. But as you get closer to your subject and the magnification level increases, the depth of field (amount of the image in focus) rapidly drops off.

In macro and close-up photography, depth of field is so narrow it is usually measured in millimeters. So taking photos where more than just a thin sliver of the image is in focus can be tricky.
