+1 Topaz Clarity
I've not tried their 'Detail' product but their Clarity tool has saved more than 1 of my images, similar to yours except instead of snow I had blazing yellow & orange New England Fall colors that seemed to be hopelessly blocked up although it did leave it w/ a tiny bit of that HDR look
Hi Howard,
Depending on what you wanted to accomplish, maybe a bit less of 'Clarity', and a bit of added 'Detail' would have been even more to your liking.
'Topaz Clarity' affects the effect that lighting has on subjects, the formation of light and shadow, by adjusting local and global contrast. It also has good HSL controls, with separate masking capabilities, to affect the color rendering.
'Topaz Detail' affects surface structures, either amplifying them or reducing them, but with a lot of control.
I consider both as 'must-haves' in my workflow, besides Capture and Output sharpening tools.
Cheers,
Bart
