Thanks for all the photos you've posted. In this recent photo of the flower man, did you do contrast PP or is this how the scene looked?

You're welcome. Hope it's soon for you and that you love it as much as I do mine. Here's a photo taken at lunch today – not to prove anything beyond the fact that I'm enjoying shooting more than eating ... even snapshots. 135/2 at f/2.0 ...

So if you shoot everything at 3200ISO you will never see any banding? Cool.
My base iso is 800, and at that the colors, sharpness, noise, etc are excellent - so I don't really care about deep dark banding at an ISO I almost never use. If I do go down to 100 for a shallow DOF portrait in bright daylight (which in itself sucks as a concept) I know not to screw up the exposure.
I have no doubt that it is an issue for some, but frankly I have never once (in >100K shots) ever had the issue. The reason for 5d3 is the stellar AF performance in cave-like lighting, which indeed is an issue all the time.

Perhaps, but the evidence suggests otherwise.
Most of the whining and crying seems to be coming from those who prefer to shoot with their lens caps on.
and most of the whining and crying seems to be coming from those who either have no idea what they are talking about but like to poke insults at people or who only shoot under very mild, controlled conditions 100% of the time

If you are pushing the shadows 3-4 stops regularly, you need to look at your technique. At 1-2 stops it's a non issue.
not actually
and phrasing it like that gives a subtle implication that something weird or wrong is being done, when it nothing the slightest bit is being done differently other than shooting a scene with more DR than another scene

You're welcome.
No contrast applied ... just a touch of burning on a couple of too-bright leaves, and a light dodging of the man's hair and face so he's a little more obvious. I just added links to the original JPG and RAW images, and here they are again:

Thanks to Don again. -1/3 ec is alright for black frame.
My adventure of the Speckled Band (apologies to Sir A.C. Doyle):
Having been initiated by this forum into the fine art of lens-cap photography, I tried the above experiment with my 5d2. I noticed that the above 5d3 example was an 8 seconds exposure. So I did the same thing, with various lengths of exposure.
a. The 5d2 has both horizontal and vertical banding
b. However, the banding seemed much worse at the 8 second exposure compared to the 1/250 second exposure.
1. Is this an illusion on my part, or is it real?
2. If it is real, what is the physics behind it? I believe the banding is what is left after the camera electronics' attempt to subtract read noise - so is this subtraction becoming worse the longer the exposure, because it is an analog subtraction, and a charge on a capacitor is slowly leaking off?
3. If this is real, does the banding effect become even less relevant at higher shutter speeds?
PS: On my screen full size, the effect is more pronounced than in this 1024x647 on the web. In fact, here the vertical banding appears more pronounced at 1/250 seconds.

That above 5D3 example shows WORSE banding than other 5D3 frames I've seen! In the low-ISO frames from other cams, the horizontal banding is considerably reduced as compared to 5D2 banding but that above 5D3 example looks just about as bad as the 5D2 frames you are showing here. Possible that the above 5D3 example looks so bad because of its 8 second exposure?
Why all the horizontal banding? Tests of the pre-production 5D3s were indicating that low-ISO horizontal banding had been near-on eliminated in the 5D3.

Sometime you won't see any banding until the wildest DR hit your lenses. We all know banding signature is a function of DR. My 5d2 chokes after 9 stops. 5D3 banding test has not been done in real life yet

wait is that from a 5D3??
that looks way worse than any pre-production black frames and the read noise is worse too
why does it have horizontal banding?
i did a black frame from another release version and the horiz banding was not there
the fact that an 85mm lens was on it does make things worse though, it might explain some, since if a lens faster than f/2.8 is detected it artificially and secretly boosts the gain under the covers, i wouldn't think it would reveal horiz banding that wasn't there before though, but it would explain worse read noise
hmm but it was shot at f/3.2 so I'd think that would've been ok, so never mind
oh but 8 second exposure, i've never looked at black frame from longer than around 1/125th and mostly 1/8000th maybe 8 seconds brings out bad things

Alright ruhikant...That's just awful...Look at all that purple fringing, the awful highlights, the off color reds and there must be other stuff I could complain about..But by now you can tell I'm not serious!!!That looks very workable and much better than the inside of a lens cap!!! Can't wait to start seeing much more real world shots from these!!! Oh, and just in case I didn't say it...Nicely done!!!

Just to be sure, I was just sharing the link that someone posted on POTN, it is not done by me.
