Scanning some old/dirty/fungus damaged slides. Kodachrome and color positives. The iSRD is working well on these but seems to not work on fungus issues. I think because the fungus damage is IN the film, not ON the film.
Will select the sky areas with the pen path tool in SRDx and apply strong or Max strength. You can add to the selection, but it will be at the same strength. Doesn't seem to a allow and second mask. If you export, close SF8 HDR, when you reopen it seems to remember the mask and won't allow a new one.
In the Ps plug-in I can select the foreground, apply less strength, and use a layer mask to paint it in using different opacities. I have tested on only one image but seems to do exactly what I had hoped for. Seems you can only have 1 path selection there also. It works like a healing tool and is much better than using Ps Dust & Scratches.
And Yes; I would recommend this product to a friend.
