Banding question
Good Evening Folks,
Is mid to high iso banding an issue that is camera (hardware) related, or the result of operator error due to under exposure ? I was testing my 5D2 earlier tonight with the canon 35 2.0, and a few shots of the dark sky appeared to have banding at iso 3200 and iso 6400. Other then that, the images were unbelievably clean, sharp and detailed. Thanks in advance :thumb

Usually banding comes from excessive post processing.
Thanks for getting back to me I have to see if I still have the pictures. I was just playing around with the camera, and noticed the band in the sky, in certain parts of the picture. I didn't pp much, just basically converted from RAW, and played around with the White Balance and Picture Styles.

Natural selection is responsible for every living thing that exists.
D3s, D500, D5300, and way more glass than the wife knows about.
I was shooting sRAW1 only, converting to jpeg in DPP, playing with the WB and Picture Styles. That's it. I'll post some night time, outdoor shots in the next day or 2. Inside shots are not a problem.

Good Evening Folks,
Here is a shot taken earlier tonight at iso 4000. The areas in question are on both sides of the pole and in the upper corners. This pic was converted from RAW with no pp, and downsized. The RAW shot looks just as bad. So, would this fall under a banding issue or possibly an amp issue ? Thanks in advance

Thanks for your answer If that's the case, then this is normal when a pic is under exposed ? I didn't have that (underexposure) problem with my original 5D, and I took quite a few evening shots with lots of sky visible. I'll have to start shooting to the right of the histogram to get it correct. Thanks again.

Banding is also exacerbated by using intermediate ISO's, 2200 is especially bad on the 5D mk2 sometimes. Also, warmth is never a friend of clean images; colder temperatures will always reduce noise although I don't know if they can influence banding.
Lastly, sRAW1 on the 5D mk2 is also prone to horizontal banding, in under-exposed areas. :-(
Chances are, you're just not getting your shadows bright enough. That sky looks mighty dark and at ISO 3200, any hint of brightening in post-production could bring out banding. In such a situation, there is not much you can do except brighten your exposure as far as acceptably possible, and then worry about preserving highlights instead of saving shadows... Shadows always get completely trashed at higher ISO's, while highlights still maintain some amount of recoverability...

Thanks for your answer I wasn't expecting any issues with the 5D2. Never had any trouble other then operator error with my 5D. I'll shoot RAW from now on and just expose to the right, like I mentioned earlier. Thanks again.

Hi Jim, Yes. I'd venture two things, underexposed AND high ISO. If you'd have under-exposed it more you'd have seen the banding better. I haven't seen it as much on my stills as I have my Video when pushed to under-exposure and high ISO.
What I have seen is splotches. Like I see in yours. Noiseware wouldn't deal with it, but crushing blacks did.
Morning Folks,
I appreciate all the help from everyone I should have also mentioned that I was viewing the images on my laptop at work. When I put the pics on another computer (desktop) I could'nt see anything unusual in the sky. It was more of a dark uniform color. One thing I am impressed with, is the low light capability. Since I always use center point af, I wasn't expecting any problems with focusing. I must say, I wasn't expecting to capture the following image by just using a small 3'' flashlight to illuminate it. Iso 6400 looks really good. I printed out an 8 x 10 earlier for a contractor that I'm working with, and he couldn't believe I was able to get a shot like that. Needless to say, I was very impressed. Anyway, again thank you all for your help
Have a good day
Jim...
