Hi, Neil again,
I have two questions for the forum this time concerning stair stepping or pixelation.
I shot this image using a 5dii and a 135mm 2.8 @ f11. At the time I was concentrating on focus stacking and didn't pay much attention to the pixelation on the arms of the sunglasses. Now the setup is tidied away and I think I have to reshoot...
So, I'd love to know what went wrong and how to avoid the stair stepping pixelation again. I think I read somewhere about the ant-aliasing filter on the Canon's sensor being arranged horizontally. I shot this picture vertically. Btw, the pixelation is present in the Raw files, it's not a resampling issue. I think you should also know I shot it in sRGB and processed as a 16 bit tif.
Secondly, is there a Photoshop method for removing the stair stepping?
Thanks in advance, Neil.
