Truly amazing photos. I have always wondered about the key component in getting such great color and sharpness. Obviously my $200 Elf isn't up for the job, but with your D90 can you get results like yours using the "point and shoot" setting (I assume it has one)? I have way to many hobbies to be taking on photography, at least in really learning f-stops and shutter speeds, etc, but I really want to capture the better moments in life with the quality that you have.
I am not trying to derail your thread, a simple "yes, the auto setting gives these results" or "sorry, not that easy" will be helpful.
