background replacement and banding

[diamante67]

In the attached picture, I replaced the left side of the wall with a gradient and added noise (10%). I am still seeing banding in the photoshop image unless I zoom in at 100%. How do I figure out if the banding will print out badly and is there anything else I can do to eliminate it, if this is a problem? (faces "obscured" because I am not allowed to share). Added the 700px square crop of the banding region, in case it helps.ETA: the high res jpeg does not look bad so maybe it's ok?

What about at 50% and 25%?  Banding or no banding?

[diamante67]

I still see some at 50%, I think.

Ok, I don't think that's cause for concern.  As long as it's not there at 100%, you'll be fine.

alright, thanks for your quick response.
