Amd the recommendation is to work at 1:1 zoom (or failing that, to use the small 1:1 preview window inside the Detail panel) so that you can see what is happening with the pixels and the picture content in its own local terms. For example, you can change the pixel radius over which sharpening is determined. The sharpening controls inside Lightroom Classic work on pixels. Masking is, I think, similar to Radius in that it’s going to be about nearby pixels and not affected if the overall pixel dimensions change.Īnd the reason others asked you if sharpening was applied in the Export dialog box is because by its nature, output sharpening can be affected by pixel dimensions and output targeting, for example if both versions were exported with output sharpening set for printing.Detail is related to detail frequency, so again its result should be the same for a cropped and uncropped version.(However, the identical result of the same Radius value can be perceived to be different if the cropped version is reproduced at a different pixel density (ppi) than the uncropped version. Radius is related to nearby pixels, so if neither version of the image was resampled, Radius should have the same result before and after cropping.Amount is a sort of amplitude which I think is not spatial, so the same amount should produce the same result regardless of pixel dimensions.
No difference is what I would have suspected, because of how sharpening works (hopefully this is correct) I think none of the following Lightroom Sharpening options are related to or affected by changing pixel dimensions such as by cropping:
DIFFERENCE BETWEEN LIGHTROOM CLASSIC AND CC SOFTWARE
This posterization is not in the original animated GIF file the forum software seems to recompress this format.) (The image colors may look posterized in the animation. This is why many people use the Difference mode to manually align layers, especially when automatic alignment fails. This indicates two things: There are no differences between the images, and because there is no difference, they are perfectly aligned. At one position, the cropped image appears completely black. The cropped image is repositioned, to manually align it with the uncropped image. Black pixels indicate no differences between the layers.ģ.
The cropped image layer is set to the Difference blending mode, because this mode reveals any differences between the selected layer and the layers behind it.
The two images are added to the same Photoshop document, not yet aligned.Ģ. Neither image was resized or resampled, simply layered 1:1. I understand that the two images you posted are JPEG format and not the original TIFF format, but even then, after aligning them precisely in Photoshop using the common Difference mode technique, there seems to be no difference between the cropped and uncropped versions.
