Given how well Adobe’s Super Resolution feature worked on digital images I was curious if it would deliver the same results on scanned film negatives, so I tried it with two photos – one shot on Ilford Delta 100 and another on Ilford HP5+. While I normally scan my own images I used scans done by the local store where I get my film developed. I believe they use Noritsu scanners.
Below are the original and enhanced images from the scanned TIFF of the Delta 100 negative. The original is 3999 x 2666, while the enhanced is 7998 x 5332. As with previously enhanced images I think the outcome is excellent and the larger jpeg is essentially indistinguishable from the original. In particular I don’t see any negative impact from the detail enhancer on the grain.
The next shot is with the grainier Ilford HP5+, but despite the grain I got the same excellent outcome. The original scan is 4917 x 3276, while the enhanced image is 9828 x 6552. As well as being able to print bigger an additional benefit specific to film scans is that instead of trying to stretch my scanner to the limit on resolution, I can now scan at a slightly lower resolution and then upres using Super Resolution. As with previous posts you can download the images and make your own comparison. Right click on the image and select ‘open file in new tab’ to get around WordPress’s image scaling.
