I went recently in the fenestrelle fortress, Italy.
I’ve took mainly .DNG file photos with the smartphone but I’ve used a slighty different kind of sharpening than my usual.
The main idea is that when local contrast is added to a photo then some details are clipped.
The simple solution is to compare the sharpened version with the original version, if something is clipped we just use the unsharpened pixels, basically it’s like a threshold.
My workflow was to export an unsharpened and one sharpened file from the raw converter, then I’ve used the custom blend layer mode in g’mic where the sharpened file is the top layer and this formula:
“b=if(b==0&&a>0 ,a ,b);if(b==1&&a<1,a,b)”
With other low contrast pictures without a true black or white point, I’ve first found the min value and the max value, like this one
I think the effect of this kind of threshold isn’t something that totally change a picture but it could help to gives a more clean and sharpened photo
