Resolution in digital imaging: enough already?
Digital images have become the new currency for the exchange of information in dermatology. The main value of the digital image, its ability to be transported via the Internet, is optimal if the image can be shared by all interested parties without the need for the still relatively uncommon broadband connection. The technology behind these captured images is progressing rapidly with a resultant increase in image size and resolution. For all practical purposes in clinical dermatology, the current technology with regard to resolution has already gone beyond the needs of the clinician. This article, using freeware and commercially used software, offers proof that a single megapixel image is adequate for on screen evaluation and publication purposes.
