Just a suggestion - before you start taking all pictures at the maximum megapixel capacity,experiment shooting at a lower resolution. It will increase the number of pix per card, easier and faster to manipulate in photo software and uses less space on the hard drive. I make prints up to 11x14, and project digital images to an 80 inch screen with a DLP projector and see no difference when I take photos at a "medium fine" setting compared to the highest resolution. I used to do my own color printing in a dark room - what an incredible revelation digital is! No more film for me!
