This is a question about how BEST to handle a situation.
Image 5616x3744. I want to use a section ~1820x2300 to make an 11x14 print at 240ppi.
I did basic processing in Lightroom, then additional processing in Photoshop. From Photoshop I invoked the Photo AI plug-in and did noise reduction and sharpening in Photo AI. It is not possible to do an upscale from the Photoshop plug-in, so I saved the finished image in 1X back to Lightroom.
I ALSO saved the PRE-Photo AI image to Lightroom then ran Photo AI on that image from Lightroom, upscaling to 2X and doing what normal noise reduction and sharpening - I’ve found in recent tests that minimizing ALL the values in the upscale section and doing “normal” noise reduction and sharpening works best with V2. I used the same settings for noise reduction and sharpening on both images.
After all the processing, crops were 1824x2322 for the NON-upscaled image and 3649x4644 for the upscaled image. I exported both images to 14x11@240ppi, so the non-upscaled image was increased by 45% and the upscaled image was decreased by about 38%.
When I LOOKED at the images at 100%, the noise appeared the same on both images, but the undersized image was sharper - not much but at 100% it’s perceptible.
This SEEMS backward to me UNLESS I need to process the upscaled and non-upscaled images differently, but when IN Photo AI at 100% they looked the same as near as I could tell.
So, after all that, the question: In a case where you have the choice of upscaling the image in Photo AI then having it shrunk to fit the output versus NOT upscaling in Photo AI and increasing the size when it’s exported from Lightroom, is there a “better” method?
