I recommend using TIFF format rather than JPEG in these steps to avoid any possible data loss in compressing the file -- the LZW compression option for TIFF is lossless. JPEG format should be reserved for the final output only whenever possible.

Banding can also be a display issue, if your monitor is set to display fewer than "millions" of colors, or if you are looking at the image (in Photoshop) at a sub-optimum magnification.

An "artifact" you see at some arbitrary enlargement (what you might get with "fit to screen", e.g. 19.6%) might "disappear" when viewed at 25%. For critical evaluations display at 100%, 50%, 25%, 12.5% ...

ETA: Yeah, and try to work in 16-bit mode when you can (like in TIFF). :-)

i'll check out your suggestion .. hopefully it will help .. xx


Here's the catch with your workflow; when you save as a JPEG, you squash the color depth down to 8-bit. There is no recovering the lost bit depth. Try saving as a 16-bit TIFF, then opening that in Ps. Your banding should be miraculously gone.

If you use RAW files you can use the Defringe function. It’s in the Optics selection below Vignette. It may help.

i often see banding when i'm editing my photos .. sometimes when i've not done much to them at all ..
i've been online looking for ways to get rid of it or at least make it less obvious ..
some of the suggestions were to add more noise .. but that didnt work when i tried it on my photo ..
i'm working in 16bit btw ..
does anyone here have any advice ..
and thankyou in advance ... :)
