+Generate UltraHDR JPG images from various combinations of source files (SDR, HDR, gainmap).
 
 https://developer.android.com/media/platform/hdr-image-format
 
-Of all exported files, the storage detects pairs of files generated from the same source image, 
-assuming the first one encountered is the base SDR image, and the second one is the gainmap
-(alternatively, you can tag the gainmaps with a "gainmap" tag).
-
 The images are merged using libultrahdr example application (ultrahdr_app).
