Unsolicited help

Dana Hunter made some nice pictures of stones-if I might be so ignorant in this case and in this case only-here. I took one of these pictures (the corner of a sandstone pillar) and tried The Gimp for a bit of enhancement to the visibility of the stone’s structure. Could not call it a complete failure, but could be better.

The original picture, reduced in size by 50%

Sandstone-step-01-raw-whitepoint-halfsize

Color Correction by setting the whitepoint

The automatic did not work here, so I had to set the whitepoint manually, somewhere at a very bright spot around the fingernails.

Sandstone-step-02-raw-colorenhanced-halfsize

Slight color enhancement

Enhanced the color with the Ultra-Vivid tool from the FX-plugin with 10% opacity. I find that much simpler than fiddling with the settings of the plugin but YMMV, of course.

Sandstone-step-03-raw-colorenhanced-layer-mid-darkened-added-by-valu

Layer with Mids darkened and added by value

Sandstone-step-04-raw-colorenhanced-layer-mid-darkened-added-by-value-contrastenhanced-halfsize

Contrast enhanced

I tuned the contrast a bit with the contrast/brightness changer of the FX-plugin which uses matrices to do that.
