I thought I would start this thread (because I couldn't find one like it) to help people that might know some of the terminology like "LOL: laugh out loud" or "DOF: depth of field". As I was reading through some of the threads, I had a hard time with some of the abbreivations. So if you have any please put them here so that we could make a list for those new to forums and/or photography would have a place to start the definitions. L o L: laugh out loud DOF: depth of field IOM: ? KFC: Kentucky Fried Chicken Opps how did that one get in here Negative Density Filter: what does that do?
