I read that LF photography is often performed at very small apertures. Seems like anywhere from f/22 to f/64 is frequently cited. But in practice, what do you use? For stills? Portraits? Landscapes?

I am new at LF photography, so I thought I would just try a comparison. Here's a hat of mine, first at f/5.6, then f/8. DOF is shallow, especially at f/5.6

The first doesn't really seem usable, but by f/8, things look better, and the DOF could be quite useful, depending on the situation.

So, again, in practice, what f-stops do you find that you use the most. Do you ever shoot wide open?
