I was playing around last night with a new function in Photoshop that significantly increases resolution of the original RAW file – effectively by four times. It is very simple to use. I loaded the raw file (in this case an infra-red shot from the Sony A7 III of a nicely lit birch tree) into Adobe Camera Raw, right clicked on the image, checked the “Super Resolution” box a few minutes later I had a new file in DNG format that was four times the area of the original. In other words instead of a file that was just over 4000 px on its long edge, the new file was now over 9000 px on its long edge! That is a huge file which needs a fast PC to handle it – mine (which is around 6 years old) was only just about capable.
Now look, I am a skeptic, so I simply assumed this new file would show artifacts and overall there would be a degradation of image quality. Not so. To me this new ‘super resolution’ version was higher quality than the original, with superb detail and no artifacts I could see. Its incredibly impressive. Although I have more experimentation to do, I am really impressed by what I have seen so far. I can see some mega useful applications here – e.g with wildlife (especially birds) the subject is often smaller in the frame than I would like. This new function will give me the ability to re-size, process and crop back, whilst retaining great image quality and with a final file size large enough to print really well.
