In the last post, I showed you images that resulted from scanning 4×5 TMax 100 negatives with a Nikon Z7 in this setup:
The results were good enough for excellent 17×22 inch prints, but there was more in the negative than the camera could resolve, which we saw by loking at better-quality scans using the GFX 100S.
Using GigaPixel AI for upscaling showed unacceptable artifacts. But that gave me an idea. What If I use the Enhance Details demosaicing method of Lightroom in the mode that results in doubling the resolution of the file?
Here’s the test scene:
Here’s a crop of the Super Resolution image scaled up to 19710 pixels wide, and magnified to 140% for the web:
Here’s the same view with noral Lightroom demosaicing:
And here’s what you get with normal demos acing and the GFX 100S
It’s hard to judge because Enhance Details SUper Resolution sharpens so aggressively, but the results appear to ba an improvement over the regularly demosaiced Z7 image, but not as natural as the GFX 100S image.
Here’s another section of the image, at 100% magnification from the 19710-pixel-wide images.
There is still some unnaturalness in the Super Resolution Z7 image, but I don’t think you’d see it unless the print was fairly large. I’ll do some testing.
