About retroReveal
Mission Statement

retroReveal provides documentation and web based image processing algorithms designed to help people discover hidden content. While the current version of the site provides basic assistance with image processing, we will be adding support for collaborative work among scholarly communities in a wide variety of disciplines in the future. retroReveal provides an inexpensive discovery tool to assist people who wish to identify hidden text in their documents for further study. The web based image processing we provide assumes no specialized image editing knowledge, and is designed to be used by a broad spectrum of researchers, scholars, and community members.

Reading faded or weak strikes of postmarks or other auxiliary markings is often difficult to impossible; however, the capability provided by the retroReveal website may be allow you to discern some or all of the markings.
As an example, here is a postmark taken from a post card sent from Mexico.
There was no date included in the sender's note so I had no idea when the card was postmarked -- circa 1934-1940, the stamps's approximate period of use, was as close as I could come.
After uploading the image to retroReveal, and subsequently processing it, this enhancement of the image revealed that the card was postmarked March 8, 1937.
The best part about the site is that you only need to know how to upload an image; all of the image manipulation is done "behind the scene," and in under a minute you are provided the analysis.
