I always get a thrill out of discovering rock art. Sometimes the pictographs and petroglyphs are quite clear and easy to see and photograph. However, more often than not, the images are faded and difficult to decipher. I recently became aware of some software programs that help to enhance photos of rock art.
One program is called DStretch, which can be found by doing a search on the Internet. But first, you will need to download another program called ImageJ. DStretch is a plugin for ImageJ. I am still learning how best to use these programs; but in the meantime, here is an example. Check these programs out, have fun, and send me some of your results at swa@infomagic.net. Thanks.
