All I wanted was to share the Featured Image, converted to JPG from RAW. More than an hour after I started said process, progress was zero. The photo was pixeled in Adobe Photoshop Lightroom and editing option was greyed out. No online search, even with Artificial Intelligence insight, revealed any discernable solution.
I worked on ARM-based Samsung Galaxy Book4 Edge, running native Lightroom. I eventually abandoned the effort, because the night waned away; I don’t like to give up without solving something. I instead processed the NEF file on Intel-based Microsoft Laptop Studio, which is older and considerably slower—and with atrociously disappointing battery life.
