1dmk11n banding issue

ok i have a 1dmk11n about a month old, i shot tonight at 1600iso and noticed banding in one of the jpegs but not its corresponding(sp) raw file. my question is to the others experiencing banding, is it only in your jpegs?

was the jpeg processed in CS auto settings?

i have auto settings off in cs, and tried it in microsoft picture viewer which i figure is a basic prog that wont manipulate photo and still saw the banding. banding wasnt in other similarily framed photos taken within seconds


edit: double checked its in some raws too and more jpegs, mainly in dark sky, not visible in some pics till exposure raised

Post some sample pics.

It's there, but very difficult to see if you're not looking for it. Doesn't seem serious. And it can easily be fixed in PP. You said this only happened in this one shot right?

in a bunch, those two shots were more prominant, pretty much anything shot at iso 1600 with lots of sky. 800 iso was fine.

I dont have a 2N (yet) but have heard of this problem. Not only in the 1D models but also with other cameras. (5D 30D 20D) and as of last night I saw it in my XT in RAW but only when exposure was extremely high, the difference was my ISO was at 100. This isnt the first time this has happened. Im thinking its with low light and overexposed shots. At least that is what has happened to me, but I could be wrong.

[Story] There is a woman in work who has the most disgusting eating habits. She 'troughs', talks with her mouth full, chews with her mouth open and generally upsets everyone with the way she eats. However, I sat in the staff room blissfully unaware of this behaviour until someone pointed it out.[/story]

What I'm saying is that I didn't take much notice of banding in my some of my images until someone mentioned banding. Then I started looking more closely at them and what I found was this. This is a 100% crop of an image at 1000ISO, 1/80 using a 24-70L. I think it was overexposed by one stop to up the shutter speed.

tag please if you remember let me know the outcome. i can live with it for now, but if they can fix it i would have to take it in. im not so sure that all 'ns dont have this problem when exposed improperly in high isos.

I've noticed the same on mine from ISO 800 upwards. Now I didn't notice it before the last firmware upgrade, but this could be (and probably is) coincidence!

Actually FatPete, these images were before I updated to the last firmware. I didn't think to try it after updating. I suspect however, the issue will remain.

nycgrip, I'll keep you posted on my outcome. Cameras shouldn't have this problem. I tried all different combinations with my 10D and apparently no banding. If this problem occurs when you overexpose by one stop then what is the point in bracketing an exposure? If you wanted to do some HDR then you couldn't, could you?

had an idea, so i checked the operating temperatures of the mk11n and they are 32-104f. and it was below that when pictures taken. possible factor?

The 1Dinosaur is known for banding at ISO above 1600. I've seen this, but it's really not that big of a deal for me. I don't expect it to be as prominent in the later incarnations of the 1D though. But if it does exists then so be it. I can live with the occaisional banding.

I'll post up a shot tonight at 1600 when I get home - may also get in touch with Canon to see what they say, although it will really cripple my 'photo-per-day' project if I have to send it away for a few weeks
