These images are exactly what you see when you download them from the camera to the computer. No cropping is necessary. The occlusal shots are upside down since they are taken with a mirror, and I have flipped them above for better viewing above. You can purchase a side flash (it is bulky) to eliminate the shadow that appears on the side face shot (or get a light for the records room that will do the same thing), but I can zoom in to this shot and see the soft tissue profile adequately enough for my diagnosis that I have not felt the extra expense is justified.
These images were taken with the high quality (HQ) setting on the camera (this is the medium quality setting). The resolution is 1712 x 1368 pixels. The highest quality setting produces images of the same resolution, but it saves them in a format that is less "compressed." Since this resolution is higher than the resolution that I have my monitor set at (800x600) and is higher than the resolution that I typically print the images out at (720dpi), I have found the medium setting to provide excellent quality with more information than I usually need. The lowest setting produces adequate images, but if I really want to zoom up close to see fine detail (an area of hypocalcification, etc.), I like the medium setting the best.
For purposes of posting the images on the web, I resized the images to 72dpi (the resolution of most monitors) and reduced the image size by 50%. I then increased the amount of jpeg compression the reduce the file size (about 20kb) to make the download time acceptable. When downloaded from the camera, the images are about 530k in size.
