AndroidDStretch is available on the Google Play Store.
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
very poor pictures for DStretch. My old Samsung Galaxy S4
took poor pictures. There are camera apps, Open Camera and
DSLR Camera that may improve the images. My tablet
(Samsung Galaxy Tab S2) has a great display, an OK camera (but
no flash), and is very fast at doing the enhancements.
Some images to play with. Download them to your device.
