It really depends upon what you intend to do with the images.
Digital photography has many levels at which the surgeon can enter the medium.
They might have waited a year or so to find many inexpensive camera systems popping up. The surgeon primarily needs to document and index patient outcomes for both practical and legal purposes. As I am not personally an advocate of the morphing aspect used in many marketing systems, I will not address it here. Fortunately many of the contacts I made during the research phase for the PRS piece are predominantly willing to continue to supply material for this feature. New items will be reviewed as they arrive.
