Although most orthodontists can rely on their orthodontic image software, those who have the need to go beyond just the monitor display of the images will need to get behind the scenes. Understanding a little of what makes up digital images and how to manipulate the variables will enable them to get optimum image quality as well as conserve on time, file size, and storage media. For those who import bitmapped images into digital presentations, the ability to adjust these variables can enable them to create presentation files that are manageable in size, will display without delays, and are of optimum resolution.
