Here are some photos I took this weekend at the local ice carving festival in our home town. I've started playing around with raw files this winter, and I'm still getting the hang of the conversion process. Since there was a lot of snow (meaning very bright) and it was crowded, I adjusted the exposures after the fact. I've been using Adobe Camera Raw and Photoshop Elements. Also, this was my first chance to use my Christmas present -- a Canon EF 70-200 L f/4 IS lens. The first half of the photos were with this lens, before I switched back to my Canon EF-S 17-55 f/2.8 IS lens (the 70-200 was too tight for the subject matter).
I would be interested in any constructive criticism on my raw conversion and Photoshop technique. I mostly adjusted exposure, fill lighting, black level, color saturation and sharpness, usually trying to use all settings in moderation.
