This page opens an ImageJ applet with DStretch plugin. Use it to enhance the image.   It may take a few
moments for the applet to load the first time.
The orange buttons perform standard DStretch enhancements.  I usually try LDS, CRGB (or LRE) and YBK.
CRGB and LRE emphasize reds.  YBK emphasizes blacks and yellows.  LAB emphasizes whites.  LDS (and YDS) give
good all-around enhancements.   Follow YDS with the Sat button to reduce the saturation of the enhanced colors.
I needed to use a flash to get these pictures.   To even out the flash lighting use the flat button before enhancing.
