Wavy banding in the sky

A few images I have uploaded have been rejected due to wavy banding in the sky.

Seems to be an excuse for uploading a photo on a cloudy ish day to me?

Does anyone have any advice or suggestions? It seems pointless to bin off a decent photo for the slightest bit of 'banding', just my opinion of-course.

Appeal it. Most of the time this works. As a test, I’ve reuploaded a photo (which was already accepted) and see if it will be accepted again. But no, this time, the same picture was too dark and jpg compression was visibe. xD

Well, I can see the banding in the sky as well. Try to check it before you upload the image, cause the screeners will use the equalize filter while screening the images.

What do you mean by banding though? What creates it? Is it just the cloud formation that is not acceptable.

When you hit the equalize filter, you'll see "banding." It looks like waves of digital noise in the sky. Sometimes it is from over processing, sometimes it is from using a cheaper lens, and sometimes I guess it just happens. I have had many shots I thought were perfect in terms of exposure, only to see the banding with very little post-processing.

It's frustrating I know but not to worry, there isn't a person on this site who hasn't had this happen.

Best,

Most of the cases will be from over processing. Your original photo will most likely have 'waves' in the sky but they will be a lot more grainy and there will be hardly any contrast between them. If you need to process the image the way you have, deselect the sky in order to avoid this. Also, most blur tools will create this effect too. Keep the strength of the settings lower for the sky or repeat reduce noise a couple of times. As others have mentioned above, always check your image with the equalize filter.

Hope that helps

Would this be the same as "stepping" in the sky? had a couple rejected for that reason.
