William Mohr submitted this image taken with a Canon XSi, with an exposure of 1/750 sec, f/5.6, ISO 400. Go ahead and straighten you horizontal line across the middle of the frame. Try to keep the main part of your image out of the center of the frame, in this case moving the line up in the frame would allow more hand and give a better feel of what is going on. This is an almost. Interesting idea, but leaves you wanting more information.
