Now you can perform DStretch enhancements in the field on your Android phone or tablet.


AndroidDStretch is available on the Google Play Store.Google Play

See the Google Play page for screen shots and description.  See the iOS page for more general information and examples.  Much of the iOS info applies to Android.  DStretch requires good color resolution. This is not always the case for cameras on Android phones.  I recently updated my Android phone to an LG G5.  It has two cameras.  One is a normal camera which takes good pictures for DStretch.  The other is a wide angle camera that takes poor pictures for DStretch.  My old Samsung Galaxy S4 took poor pictures.  My wife's S7 is the same.  It seems Samsung likes to smooth the colors and assumes no one will notice. Google also does this on the Pixel 2, but not if you use HDR mode in which case the images are good.  Unfortunately the app camera interface cannot take pictures in HDR mode.  On the S7 you can set the camera to "Pro" mode which saves the raw data, this option is available on the LG G5, but not on the camera app on the Pixel 2.  Open Camera is a camera app for all these cameras that allows you to save the raw data as a .dng file.  Then you can use  an app like Snapseed to process the dng.  This gives nice images without the color smoothing.  My tablet (Samsung Galaxy Tab S2) has a great display, an OK camera (but no flash), and is very fast at doing the enhancements.
