Greyscalegorilla and Coudal Partners are asking people to contrast their best and worst photos of 2008. I took over 12,000 pictures this year (wow!) so I immediately narrowed it down to just pictures I had uploaded to Flickr. That got me down to about 2,200 (so "worst" for me was "worst that I decided to share with the world anyway" -- I'm sure there are some wretched photos in that 10,000). Thanks to Erica and Disco for helping me get it down to two.
I won't torture you with my other possible choices for worst, but here are the other photos that I considered for best (I would have made a shorter list, but I didn't have time).
