Moss and Pebbles

High Dynamic Range (HDR) macro composed from 9 exposures. It was a windy day to attempt exact registration, even with a tripod, so ALE software (version 0.8.11.2) came in handy to align the images. It compensates for motion like translation and rotation and takes different exposure levels into account, great for auto-bracketing. ALE produces a silky smooth image that completely hides jpeg artifacts, and output can be scaled up for the final image. ALE outputs the common 8 bit format found in jpeg and the much richer 16 bit format you can use in HDR capable programs like Darktable Luminance, and Krita. This one started out as a 16 bit TIFF from ALE. Then I "developed" a few versions to 8 bit PNG's using Darktable. Darktable has may features of its own. As you tweak your 16 bit image into an 8 bit version, the preview and histogram update continuously so you have very fine grained control. Finally, I used GIMP to stack the versions I generated with Darktable and used various G'Mic filters (local normalization, tone mapping, bilateral smoothing) to complete the image.
