Yeah, I don't know. They are definitely not over processed. Like I said, this just started happening and I have done some really heavy processing in the past with no problem. Let's see what others have to say. Thanks for giving it a look.

I am not saying that this is what is happening but it does look to be a problem with color depth... you will see this in 8bit color more so than in 16 bit color as 8 bit cannot handle a smooth gradient... If you can shoot some raw picts and see if the problem disappears.

It seems to be a problem between lightroom and cs6 at the moment but it is not. It is only happening when I go to save the file under 700kb. This did not used to be a problem. I have always run everything at 8 bit. I still have not looked at the camera settings yet because. Well, just because. I will play with it some more tomorrow.

CaptainC, I shoot a Nikon D5100 and shoot almost entirely in RAW(NEF). I use Photoshop Elements 9 for any PP I might do. I occassionally get banding and chalked it up to the grinding of the lens! Geesh... It was a real oops moment to read your reply. Now for the question: where in the process am I compressing the file? is it in the camera and if so what setting do I have to adjust or is it when I save if after PP to a JPEG at a medium or high quality file setting? I think I understand the issue but can't figure out where in the process I am compressing the file. Thanks all!

Kinda the same problem, you are compressing the info so small that it can not display a smooth gradient... I too do most of my stuff in 8 bit jpegs but usually with large files... I really only used the 8/16 bit as it is very easy to understand if you know the difference between the two types of files, but you have found your problem... file size.

The only way to mitigate the banding in large areas of a color that gradually changes - the sky is the perfect example - is to keep it as a high-bit file. So when converting from the NEF, DO NOT save as a jpg, but as a TIFF or PSD. If you are sending to a print lab that requires a JPG, be sure to save as a JPG Quality 12.

Some of the higher-end printers like the Epson 3800/3880 and higher, can accept a 16-bit file. That can help.

That change to an 8-bit file reduces the number of possible colors so that we get those "steps." On top of that, jpg compression by its very nature will cause banding as it tries to assign the same color numbers to what it considers similar colors.

Yep. And by the way, I forgot to thank you for your input. It reinforced what English Wolf and CaptainC said. It took less than a minute to figure out that you guys were dead on. So, I thank you all.

CaptainC and English Wolf are right.
Perhaps when you "Save as" the JPEG compression setting in your PP is too low? Or are you working on and reSaving a file more than once?

My concern was that I used to save my files pretty darn small and had no problems. Now I do. Next thing: Please don't say that my jpegs are degrading every time I open and work them. Do you know how long it would take to do this to a single file? A long, long time. Besides, Once I work a file, I hardly ever go back to it for rework.
