Learning a camera is like riding a bike right? psssh, no. Who knew that you could choose to shoot RAW or jpeg, or both for that matter! Wait a minute, ISO is in the camera and i don't have to buy special film for it. Ok, so editing is done in the lightroom-where did the darkroom go? When it has been that long since you have set your attention to something, and it has changed that drastically, it is an insane amount of new old information you have to learn. Not to mention now there are editing programs that you need to learn and all these nifty tools. WHEW! My free time, even to this day, is spent learning and trying out new techniques. Never stop learning.
