As you most likely have guessed, I am rather partial to a bit of photo editing. I use Adobe PhotDeluxe, which is a kind of like a Photoshop Lite. I love playing around with it just to see what it can do. I mostly use it for adding effects, but sometimes for some cut & paste, or to remove unwanted background objects. Having said that though, I still post plenty of shots with absolutely no re-touching whatsoever. Sometimes you just don't need it.
As for inside/outside preference, I mostly shoot outside, as I prefer natural light and natural settings. But I will certainly shoot inside on a set if the shot is meant to be indoors. Some night shots I'll do inside as well, especially in summer when the mosquitos are biting.
