Stair stepping in this case is probably an interaction of size, resolution and the display pixel size. As an experiment I took a single jpg and displayed it full size on my display and took a partial screen grab. Then I reduced the size of the displayed image (opposite of enlarging it), without altering the file, and took another partial screen grab. I combined the screen grabs, enlarging the second to bring them closer in size. Notice the display resolution added stair-stepping to displaying the whiskers when the images was displayed at a smaller size, even though the file displayed was exactly the same.
Take you image and try displaying it at different sizes and determine whether the stair-stepping is in the image or is just an artifact of how the image is displayed. If it's in the image, it's probably an issue with reducing the resolution that interacts with the image size. If there's no stair-stepping when viewed large, it's not an image processing issue....Show more →
Just explored what you suggest, jpg at 100% is clean, I suspect reducing the display is the culprit, curious if the effect transfers to a print, not that I'm going to print this but good to know.
Thanks for your help
