Ask a Photographer, Part 4

Today marks round 4 of “Ask a Photographer,” an open forum for you to ask any questions you might have about photography, camera gear, travel, adventure, or what kind of soap I use. Leave your questions in the comments below and I’ll be answering them all day long.

Please read these previous “Ask a Photographer” forums to see if your question has already been answered:

The forum is now closed. Thanks to everyone for participating!
