Okay here is something I've done more than once get my camera out play around with some settings on it then put it back in the camera bag. Soon after that I'll grab the camera bag to go out and shot some picutres. Usually after 10 or so shots I will figure out something doesn't look exactly right. The pictures might be a bit too light or a bit too dark. Maybe they are all a bit fuzzy or other some defect. This is usually due to the fact I left the exposure compensation a few clicks off 0, the iso some where around 1600 or I've gotten creative with white balance. While these little issues can be a pain they may not have to ruin a great photo especially if you are shooting in RAW format.
Here is an example of such a photo. The night before I went out to the St. Louis Zoo I was playing around with my camera in my office trying to see how exposure compensation effected my photos with a flash. I deleted the test photos and put the camera away forgetting the exposure compensation was a bit off.
Next day I walk into the zoo pull out my camera get the lens cap off and see a Grizzly Bear posing for photos. Here is one of the photos I snapped.
I bit over exposed this is the jpeg off the camera
Well that was not what I was hoping to capture.
Enter Adobe and Camera Raw here is that example.
Better I think.
Then tonight I was playing around with the photo in Canon's Digital Photo Professional. Here are the results from that tool.
Something about the third photo just freaked me out. The Bear's eye seems to be penetrating right to the core of me. This is the emotion I wanted to evoke with one of these Bear images.
This was all made possible because I was shooting in RAW and had the best source to post process. I used to think that working with a photo after you had taken the picture was cheating. I'm quickly changing my mind about that.
