Is this the one you watched? http://www.damiensymonds.net/client-photoshop

Why do you feel the need to step backwards? I'd leave the initial sharpening, do the resize to 2048, then if more sharpening is needed for web, apply it.

Do you know if they need bleed? Or is this the exact size of the file they need?

It is almost impossible for banding to exist in a SOOR, unless you BADLY under- or over-exposed the image, which you didn't do here. So this indicates a problem with your screen. Is it an iMac?

Phew! And do you see banding in the SOOR?

Oh, sorry, you need to turn on all three checkboxes at the bottom of the window.

Alas, I don't think it's possible in Elements, sorry.

Do you shoot raw?

Great!!!

Using the Image Size function in the Image menu.

What did you discover?

Oh! Well, have you re-opened some older photos to see if there is banding in them too, now? No, because you see banding in my PSD as well, remember?

Two years, but you've only started noticing this problem suddenly?

How new/old is your computer? Second question, do you have another computer (even a laptop would do) that you can temporarily plug the screen into, to see if it bands then too? We need to pinpoint where the problem is coming from.

Yes, of course. She's right, there's no banding.

Ok, yes, that was the same on mine. All right, that proves to me that there's no problem at the interface end. So it must be at the back end. Tell me, what kind of cable do you have connecting the screen to the computer?

Ok. Now go to Edit>Assign Profile. In the drop-down menu in that window, I want you to briefly try every available profile option. They will make the image all kinds of wild colours. I don't mind about that. All I want to know is if any of the profiles make the banding disappear.

Then I fear you'll just have to live with this, sorry

No trouble.

Ok, let's continue using that photo to troubleshoot. Further down that page is the download link for my PSD file. Can you download it and open it in Photoshop, then let me know when you have done so?

I figure that the first and best approach would be to saturate the sky in raw, where the data is more robust.

Gee, that's a really good screen, I think. It definitely shouldn't band. Do you see banding in this photo?

No, it's too old. It won't be compatible with either your operating system or your monitor.

Well, you'd need a wave photo to use, wouldn't you? I'm sorry, this is way beyond me. I'm throwing this open to everyone, to see who has expertise in this.

Can't you see "Convert profile to sRGB" under the "Save as Jpeg"? Bridge will change your life. Start here, then here.
