Sure! You'll need to give me the photo without your first gradient layer.

I'm fairly certain, yes.

Maybe big radial gradients?

It'll be no worse than any of the other photos on the page, if that's any consolation.

Oh gee. I'm worried too But I don't see what else you can do.

Thanks for posting. This is a very dangerous area. Please read this: https://www.damiensymonds.net/2011/05/please-be-wary-of-cmyk.html You MUST find out the correct profile to use.

Hi @dptolemy, I've just written to Kim.

Seems nice and clean to me.

Done.

Of course.

Yep.

You can't tell how to do the second gradient if you have already done precise masking on the first gradient. You need to have some space around your subject. Remember this step?

I think so, yes.

No, do your entire levels edits.

With Levels in the usual way. Make sure they all match BEFORE adding any gradient layers.

Yes I would.

Well, that doesn't seem relevant.

No, that's just a flaw of your screen. Those lines aren't in the file.

Beats me. I'm living safely in PC land.

Oh crap!!! And Brian says you can't go any higher?

That's fine, go the DNG route then.

All of this is based on this method: https://www.damiensymonds.net/preventing-banding-in-backdrops/ This one is also very important: https://www.damiensymonds.net/2012/10/using-photoshops-gradient-layer.html

Download PSD First, I selected a few stripes with the marquee tool: Then added a gradient layer: Then modified the gradient layer to make the left-hand side as accurate as possible: Then loosely re-masked that layer all around them: Then added the second layer (clipped to the first one): Finally, masked the first layer for a smooth blend, and added the noise layer.

Well, I'll be very interested to hear your analysis.
