p.1 #1 · Help..what is that?


This is just a test shot with a 5D.... 17-40L I am borrowing for a trip down to Death Valley tomorrow and I have noticed some banding at the very top of the photo. This also happened on my Tamron 17-35. Does anyone know what this is? I imported into Lightroom, lens corrected it, and then brought it into CS6 and did a few levels masks and that is it. Any help would be appreciated.


Thanks,

Mitch

Banding. Here's some discussion you may find useful. Also try chasing the links for more reading:

BTW, on my monitor the banding is very slight. Some monitors make banding appear when a better monitor or a print won't show banding.

Thanks AuntiPode. I think I was cranking my levels too far to create a darker sky and it created the banding. Thanks for the response; this link provides some really good information.

Epiphini, I have a two-monitor setup, one is good and one is so-so. On a good one, banding is barely noticeable, on so-so it is quite bad. So it has nothing to do with your camera or lens, it's a digital compression thing.
Looking at histogram per channel, you will notice that the area with worst banding is the one where red is overblown. As you were trying to bring out red colors in sunset, you also over saturated red in blue areas of the sky, and low-resolution monitors are not able to correctly map the numbers. Try to process red areas locally in Raw processor with adjustment brush so it will not affect the rest of the image.

Thanks a lot for the tip Al. That makes total sense. I need to get in the habit of tweaking more locally. I will remember this next time. Thanks again.
