Just because I like to throw fuel on the flame...
There are so many discussions about needing more megapixels with strong proponents on each side, I thought I'd join the fray with some specific examples (especially because it seems like most of the "I need MPs" side is landscape photographers of which I am most definitely not.)
Below I am posting the crop image and then the original. Again, my context is that capturing a decent shot of every athlete in the race is my number one priority. There is little to no time to worry about doing anything artistic, and often even a basic reframing of the shot is more work that I seem to have time for. So some of these are cropped because I think there is artistic value in the a portion of the original image (and 500 shots of "runner...runner...runner...runner" gets old without some creativity
), or as one example shows, simply to isolate the given athlete.
I'm open to contructive criticism if there are things I could do differently to reduce or eliminate my "need" for more MPs (or any other photographic/artistic feedback).
