andybarton Posted March 18, 2021 Share #1 Posted March 18, 2021 Advertisement (gone after registration) Hat tip to Steve @250swb for the heads up, but ACR now has an enhance function to double the resolution of your images, which may or may not be helpful. I have just tried it out on the first DNG I could find, of some trees in a wood. The "Enhance" mode has added some pale cyan fringing to the image that I have not been able to get rid of (it is the sort of shot that would encourage fringing, to be fair) Welcome, dear visitor!

Advertisement Posted March 18, 2021 Posted March 18, 2021 Hi andybarton, Take a look here "Super Resolution" feature in the new ACR. I'm sure you'll find what you were looking for!
250swb Posted March 18, 2021 Share #2 Posted March 18, 2021 (edited) Yes a big fat file, but if you decrease the image size back to match your original I think you'll see an increase in resolution that doesn't look like traditional use of Clarity, or Sharpness, or simply bloating the file size. I don't know why it would introduce any fringing except for perhaps exaggerating a subtle effect that was there. I also tried it with film scans (TIFF and JPEG) opened in ACR and the same effect is evident, more resolution. Obviously it's a software trick, but I don't think it looks artificial like many software tricks, but it needs to be tested. So for making very large prints this looks very good using big fat files, for increasing the resolution of your regular files (with resizing) it also looks good.

250swb Posted March 18, 2021 Share #3 Posted March 18, 2021 The 'new forum' won't let me edit the previous post so here is a link explaining the new 'Super Resolution' from Leica Camera Australia, the clearest I could find https://youtu.be/glxosZiBC6c 2 Link to post Share on other sites More sharing options...
andybarton Posted March 18, 2021 Author Share #4 Posted March 18, 2021 You should still have the same time to edit posts that you used to have. If not, let Andreas know and I’m sure it can be fixed. Link to post Share on other sites More sharing options...

jaapv Posted March 19, 2021 Share #8 Posted March 19, 2021 Actually, one can never increase the resolution in postprocessing. There is no way to add detail that is not there to begin with. This function enhances existing detail, much like the steepening of the colour curves in LAB* or the 25-50-0 setting in USM sharpening and adds pixels by interpolation. It is a nice shortcut though and probably has a few extra tricks under the hood (content aware technology on pixel level perhaps?). (*) The cyan fringing suggests that the feature does work in LAB, which is the base of Photoshop anyway. It should be distinguished from high-resolution mode in a camera, which really increases the resolution by double exposure and pixel shifting.

Dennis Posted March 19, 2021 Share #9 Posted March 19, 2021 I don't have Photoshop installed, can't try ACR. Not sure if it's just another AI features, or it can really make a difference. Link to post Share on other sites More sharing options...
SrMi Posted March 21, 2021 Share #10 Posted March 21, 2021 I think that feature is mostly intended for older, low resolution, and for heavily cropped photos. https://blog.adobe.com/en/publish/2021/03/10/from-the-acr-team-super-resolution.html#gs.w8g5h1 1 Link to post Share on other sites More sharing options...
zeitz Posted March 21, 2021 Share #11 Posted March 21, 2021 Oddly I can't get Enhance to work in ACR. ACR complains that I don't have a Metal compatible graphics card, even though Photoshop and Lightroom both see and use the card. (eGPU - Sonnet eGFX box with AMD WX8200 card) A thing tool called Enhance does work in Lightroom, although I can't see much difference with the before/after toggle. I'll have to submit a support requests to Adobe, AMD and Sonnet. I can live without Enhance if the issue can't be resolved. Link to post Share on other sites More sharing options...

You won't see a difference toggling between the two images in ACR, except the Enhanced one will be much, much larger. Go to the enhanced file (saved automatically) and then downsize it to the size of the original, then toggle and you should see the difference.

What I mean is the enhanced image will look the same if you toggle between 'before and after', but the new version is now very much larger. To see the increase in detail you have to re-scale the enhanced image back to the size of the original file and then compare them. I don't know if it is the same feature in Lightroom, that's an interesting question, does it miss out ACR maybe? Link to post Share on other sites More sharing options...

I can't get Enhance to work in ACR even though my graphics card does have Metal support. And I don't know if Enhance Details in Lightroom Classic is the same. Welcome, dear visitor!
