Sharpen with AI

I experience exactly what Conrad_C described.

(Edit: I updated this reply because I first thought it was only about aspect ratios, but after further testing it turned to be more about the canvas dimensions affecting the dimensions of the filter result.)

This problem sounds like something I’ve read about before, and I was easily able to reproduce it in the current general release (non-beta) of Photoshop.

Short tl;dr answer:

The filter seems to lose the aspect ratio of a layer when any part of the layer extends beyond the canvas edges. Until it’s fixed, it seems like the AI Denoise and AI Sharpen filters work correctly only when the layer dimensions are exactly the same as the canvas dimensions and exactly fills the canvas (no gaps along any side).

Long answer:

The filter seems to process the entire layer even if it extends beyond the canvas edges, but the filter result is strangely limited by the canvas edges. This inconsistency makes the filter result end up looking stretched or squished. To see what is going on, run either filter on a layer where part of it extends over the canvas edge or leaves a gap, as in the demo below.

There are some workarounds if the layer you want to use AI Denoise or AI Sharpen on is larger than the canvas, but all lose any content beyond the canvas edge:

Select the Crop tool; in its options bar, click Clear so that canvas dimensions and resolution won’t change, select Delete Cropped Pixels, and apply the crop. You can also get the same result by applying the command Image > Trim.

or…

You can also apply the command Layer > Flatten Image, if you’re OK with all layers being rasterized and combined into one image without transparency.

If the layer you want to use AI Sharpen on is smaller than the canvas, a different workaround is needed. I’m not sure what might work. Flattening can work if you don’t mind losing layers and transparency.
