Comments on aDStretch for Android

★★★★★ Chris Boaze · Dec 6, 2019

Wow. Is all I can say. Very good job whoever built this. Very good job. Only a few suggestions from me and that's 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 vertical 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.

Stable and works well... Pictographs generally stand out well in enhanced images using the color spaces provided. Would be great to have area selection feature implemented on android. And of course, customizable color spaces would also be wonderful! Thanks for bringing to android!

A simple and magical tool for researching pictographs in the field or as digital files.

★★★★★ Neha Sharma · Feb 13, 2022

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 any more 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 research

It's a wonderful app until it stops working. It worked for a year then it quit. I thought it was a one-time payment but maybe not. I can't find out any more info about what to do to get it working again.

Does not work well with cell phone cameras

Description by Jon Harman Written by the developer, not by AppBrain. Click to read.

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. This is where the saved enhancements will be put.
