5d Mark iii noise at 1600

[yulia]

I was just doing some test shots and when i opened them in DPP...well, am i missing something here? i still hope that i pressed the wrong button, or chose the wrong settings...something that produced so much noise....Oh maybe i expect too much....But do you guys think this noise is fine? at iso 1600...I am not very happy with that...


thanks

That kinda looks like the noise level out of my 7d at around iso 800

Do you have any other examples?

[yulia]

here...

iso 800


iso 1250...red jacket is awful...


this one is a bit better at iso 1600 but what is this red pixel on her right arm?

I'm not sure... I don't have a 5D III for comparison, but they don't look great, do they?

I tend to import my images into ACR with at least a little NR by default, anyway. What do these same photos look like with minor processing?

EDIT: Just out of curiosity, what is the sixth serial number digit of your camera?

If you are shooting raw, and have no NR or sharpening, you will see some chroma noise at ISO 1600, even at 800.  There is a minimal amount of NR required.  Nikon does it in camera, but Canon lets you choose how much to use.
 
I went to my original raw images and turned off all nr and sharpening, and do see some chroma noise at 1600.  Not a issue, it goes away with just a touch of chroma nr.

Gheez!  Those first 2 examples with strong midtone banding at ISO 1600 are the worst I've seen from any body without a major exposure push.  That's just nasty.

Auto Lighting Optimizer is contributing to it but if you wanted to recurve the image a little in post you'd still get the same problem.

My 5D2 used to be nearly that bad with the original 1.x.x firmware at ISO 100 to 400. It's more usable now. (love-hate that camera like I do my sometimes also very bandy 7D)

Hmmm.. the image quality we thought we'd paid for...    I don't think so.

I'd contact Canon with a complaint and send them the files they'll request.  As for the red hot-pixel in the last example, it's unfortunate, but that happens on occasion.  There should be a way to have it mapped out in-camera though.  I don't know if the firmware will accomplish this on its own somehow or whether it needs to be done at a Canon service location.

I would have that looked at. My 5D Mark III is superb at 1600.

i just started using DPP and can't figure out why i can't apply noise reduction? It's grey and i can't move the sliders?...

ps

Z, 6th number is "3"

I don't see that noise in my ISO 1600 either. Could your spot metering have metered for the white background, making everything too dark, then your software automatically adjusted it back up where it should be, thus creating the noise?

Here's an example at 100% and, while not full frame, slightly cropped for usage frame:

Hi,
do you tried to turn of the Auto Lighting Optimizer?

On my 50D, it is the reason for noisy images. Specially in the darker parts of the pictures.

nice photo!
i was just snapping pictures/testing camera...so i didn't do anything to the settings...first picture metering is on black jacket and second - on pink coat

I don't see those levels of noise on my MKIII.

[RunAndGun]

Yeah, something doesn't look right.  That looks like some test images I've gotten out of mine at like 25,600.  I shot a night softball game earlier this week and a lot of the images were 3200 and 6400 and they were cleaner than that.

[Radiating]

Looks like you're using the camera without any noise reduction whatsoever and auto light optimizer on. Just change the settings on your camera, the images should be extremely clean at ISO 1600.
