Those blasted buccal shots! Hard to see and hard to be sure that the correct alignment and framing are in the image. Most of the time, I believe that I should see the final picture in my viewfinder before I capture the image. That means less time at the computer and I like that.
These shots, however, are best captured if you back out a little bit and then crop them in your image management software. iPhoto is a very easy-to-use program that works for most novice photographers; it is easy to both crop and straighten an image. The image at the top left of the blog has far more data than we want or need for a buccal occluded shot.
By simply cropping the image, we have a better composition with less distraction from unwanted objects like retractors.
