Adobe Super Resolution And Film

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.

Original 3999 x 2666
Enhanced 9828 x 6552

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.

Adobe Super Resolution

Exceptional. I think that’s the only word I can use for Adobe’s new Super Resolution feature. I tried it this evening with an old favourite from my 10MP LX3 which, when cropped to taste gives me an 8.1MP image.

I chose this image to see how well Super Resolution worked and the results are spectacular. I won’t bother with crops and comparisons. Instead look at the two images below – the first is a JPEG from the original RAW file as edited in Lightroom. For the second I saved the edited file as a DNG, opened it in Bridge and applied Super Resolution via ACR. (This slightly convoluted route is necessary since Super Resolution is currently only available in ACR but will be coming to Lightroom eventually.) The end result is a file that is twice the pixel length and height, and four times the overall area, coming in at 32.3MP.

Original – 3479 x 2319
Enhanced – 6959 x 4639

I’ve compared the two closely in Lightroom and I can see no reduction in quality in the enlarged file. The file I chose has been heavily edited and I suspect this feature might work better still when applied to the initial unedited RAW file. When it does finally arrive on Lightroom it should be possible to apply it to the RAW file then paste existing adjustments from the history panel onto the new, higher resolution file.

The two versions of the image above are full size so feel free to download and compare directly for yourself. (To get round WordPress’s irritating practice of scaling large files, right click and choose ‘open link in new tab’ to get the original full size image.)

I have many, many images taken on 10MP sensors, generally good enough for a 12″ x 8″ print, and plenty of images cropped to that size or smaller. This feature means I can now print my smaller and cropped images at much bigger sizes without any loss in quality. It also means the 24MP sensor in my X-T2 is effectively an 96MP sensor!


So, here is an image from my 24MP X-T2, slightly cropped to 22.4MP. The end result after applying Super Resolution is an image that is 88.4MP with 11,585 pixels on the long edge, meaning I could comfortably produce a three feet wide high quality print.

Original – 5791 x 3861
Enhanced – 11583 x 7722

Note also that this is a Fuji X-Trans file. Adobe applied their machine learning technique to produce a version for Bayer sensors and then did it all over again to produce a version for the relatively few of us using Fuji X-Trans sensors. As a Fuji user having learned to live with occasional frustrations with software that doesn’t always play nice with Fuji’s unique sensor technology I hugely appreciate Adobe’s commitment from the off to make this available to Fuji users.

Again, to get round WordPress’s image scaling, right click and select ‘open link in new tab’ in the pictures above to see the full size image.


My first digital camera was a Canon A520 with a small 4MP sensor. At that time I was using my photographs to illustrate my blog from Albania, Our Man in Tirana. This was back in 2005 – 2007 when the internet was not quite as zippy as it is these days and I generally resized my already small files to 800px or 1000px after editing them in Picasa, then deleted the originals. Some of these pictures are not bad but I have done very little with them, since at 800px they are not much use for anything.

So I tried Super Resolution on a few of these old jpegs and was pleasantly surprised. Here are a couple of images enhanced to 1800px for the first and 2048px for the second. They are not great but that is more a reflection of the limitations of my sensor back then and these compare very well to my ‘originals’. At 1800px I can at least display these at a reasonable size online and could even get a 6″ or 7″ print out of them. I have around 1,700 images from that old camera and I’m looking forward to reviving a few of them.

My initial impression is that this looks like a genuinely revolutionary step up in processing capabilities. The only down side is that on older, slower computers this may not work so well since it does use a lot of computing power. My laptop was state of the art five or six years ago when I got it and has a good i7 processor, 16GB of RAM and a separate graphics card, all of which help. That said, despite a message telling me processing of these images might take five minutes even the biggest of them from the X-T2 0nly took 45 seconds.
