Ha, and that was the money shot too! Glad you're making some progress restoring it.
BTW, I'm told we can expect much better results from Sharpen AI in the coming weeks as they train it further.
You know, I have 6.99 days of great shots, and yes -- that was the one I'd trade any of the others for. Not trusting the contrast autofocus on my X1D, I set focus manually just before they arrived and have at hand twelve shots all perfectly focused about 8 feet behind the group. I tried Focus Magic, SmartDeblur, Blurity, Topaz Infocus, Clarity, Detail, AI Denoise, Jeff Schewe's multi pass smart sharpen technique, high pass filters, different Photoshop and Raw developer sharpening/contrast/clarity layers of all kinds, darken only layers, and blends of many of them. I even tried rezing up and down with AI Gigipixel. I've been agonizing for the last day just trying to process that one shot, and the event leader was about to print the result for distribution to the group until I stopped her this AM.
There are plenty of artifacts that I'm cleaning up now left behind by AI Sharpen (mostly by hand blending the primary Focus layer with a Stabilize layer). But thankfully due to my large file size and Sharpen AI, I'm going to produce something that will I can see will be satisfactory. I'd post it here if not for privacy concerns. Nothing came close.
Do you know whether it (or AI Gigapixel) will be integrated into Studio and/or a PS plugin?
