i was cleaning out my house of junk the other day, and i found some old polaroids i had taken as a child. some of them looked pretty good actually and i remembered how much i loved my camera christmas present. so i decided that i want to try out some digital photography. so my question is, is it hard to get started in photography (even though i mostly just want to do it casually)? and also, do you have any recommendations for functional, inexpensive digital cameras?
