Android version of DStretch, used worldwide to make faint rock art visible.
Features aDStretch
DStretch is a program for the PC and Mac that is used by rock art researchers to make faint rock art visible.
This is a version for Android intended to be used in the field at a rock art site.
Eight enhancements are provided together with settings that can adjust strength and saturation of the enhancements.
Enhancements can be applied to a photo from the camera or from the gallery.
The enhancements can be saved.
For ease of use you can designate a default enhancement (I recommend CRGB) that is automatically applied when an image is loaded.The enhancements are: CRGB, YRD, YRE, RGB0: good for red pigments.YDT, YRD, YWE: general purpose.
YDT, YBK, YYE: good for yellows.See DStretch.com for more information on DStretch and the enhancements.In addition to choosing the default enhancement, you can use the menu to set:Scale.
This is the strength of the enhancement.Saturation.
This controls the saturation of the enhancement.
Set to 0 for grayscale, 1.0 for normal.MPixel Limit.
Android phones can have memory problems with large images.
Set this to a low value to avoid crashes, to a high value to get higher resolution for enhancements.Output Directory.

What Our Users Say
Don't just take our word for it. Here's what our users have to say about our Android app.
"I have done my Ph.D on rock arts and this app helped me a immensely. Window version is more advanced and having more features but android is more handy and easy to use. My whole analysis of rock art in Odisha was based on this software and discovered many images never previously reported & helped to identify. One don't need anymore line drawings in case of both pictographs and petroglyph. Heared talk of John Hermann described the software use very well.THANKS A lot. Usfull for RA reserch"
Neha Sharma
"I don't know what I would do without it. Its very useful if you are looking for pictographs. It can see stuff that the good old eye can't"
Don Mathes

Joshua Reeves
"Great app. Well done."

"How about an improved interface for setting the output directory rather than entering the path manually? This is really clunky! Need to be able to set to sdcard."

TIMMY GIBBS
"Wow. is all i can say. very good job whoever built this. very good job. only a few suggestions from me and thats ability to see photo names on gallery not just photos sometimes im looking for a specific photo by name. no biggie but a suggestion and also something where i could scroll like a drag verticle wheel that would scroll through the settings live on the photo im working on this way i could see all settings effects quicker than slow change by change. no biggies. never glitches very fast."
