How Do I

[Chris Calohan]

Stop banding in broad areas in the jpeg compression? I've tried just about everything in my little box of tricks that I know. Any ideas out there. Here is a prime example.

Not as bad on here as on another site....is it more an issue with the host program's method of transference?

Donno, Chris, maybe because I can't find any exif data on the picture. What camera did you shoot it with? What post-processing sequence are you using? Did you shoot raw or jpeg?, etc., etc., etc.

Don't use JPG? Just a thought. PNG is loss-less compression and might suit your needs better.

I suspect it is. I don't see any banding in this photo on my Dell monitor.

I'll give the PNG a try as well. I shoot a D800 and this image was shot with a 28-300 at f/25 2.5 seconds ISO 100

[Alan Klein]

Don't really notice banding in that shot.  Did you adjust jpeg for the least amount of compression???

A very slight sign of banding on my monitor but wouldn't have noticed unless my attention was drawn to it. I was wondering about the f/25? Was that to maximise Dof? Personally I wouldn't have gone above f/16.Maybe it has something to do with the capture? I like the image, nice processing.

You can work on banding by adding noise locally on the sky in 16 bit mode and then blurring and then denoising again.
Thats how I do it when I postprocess certain jpegs.

Looks fine on my screen...nothing near banding to my eyes.

Didn't have the Big Stopper with me and wanted to maximize the exposure time to smooth out the water. Normally, I do landscapes at f/16.

Thanks, Chris. I had already done that and was beginning to suspect it might in itself be part of the problem, but looking at this on a macpro book last night, I am okay with how it translated here.
