5D and 3200 ISO

Hi,

I regulary see nice and clean picture of the 5D at 3200 ISo, but not from mine. IF I shoot at ISO 1600 everything are fine with a very fine grain and so little color noise, but when I crank up at 3200 there are lots of white spekles particularly (visible with DPP but not seeing in PS) and colored one also, hot red pixel also appears at this level. Even if I process the image in noise reduction the white grain remain in DPP??? This is a crop of around 100% of a picture taking at 3200
Your tough and experience are welcome.

5D - 24-105mm f4L at 28mm f4, 1/4s handheld, 3200 iso

Any chance we can see the full frame for this photo?

For sure

I don't know - looks pretty clean to me.

Heh! I'm not sure about white specs, but you do need to know that noise will be in pretty much any camera at ISO 3200, and viewing shots at such high ISOs at 100% will show them.

When I shoot at high ISOs with my 5D and my 1D3 it is with an assumption that I'm going for the best exposure possible and also that the framing will be as good as possible to prevent severe cropping. We are not talking National Geographic quality stuff, IMO, but shots that as a whole are acceptable. Plus, printing often "smooths over" noise, so a lot of people report great prints at high ISOs.

In your image, you are definitely at a disadvantage because of the dark conditions. A low-light exposure will bring the worst of your noise to light. That's just the way it is sometimes. How do the pictures look if you view them at full size?

no one ever post clean 100% crops of ISO 3200s though.

Also dark, underexposed shots will be worse. You were at 1/4 shutter speed, too. All bad for noise.

Yes you'r right, it's look clean here, but when view at 50% it's very harsh in DPP. Maybe my expectation are too high and image so clean at 1600. I just dont explain why the tiny white spot disapears in PS, but view in DPP.

I concur. That looks fine as a full shot. I wouldn't sweat it too much.

Looks like the normal 3200 from my 5D. Problem is the shot is dark and the crop is from an underexposed area.

If you want noise, go shoot some neopan 1600, or elford delta 3200. FIlm grain will quickly desensitize to the noise of most digital cameras of today.

Quick examples of neopan 1600:

Thanks, you are right, 1600 film are more like if not worst than a 1600 one on a crop sensor.

Just for reference, here are a couple shots from my 1D Mk III at ISO 3200, with some Lightroom noise reduction applied. You can see noise, especially in the first shot in the water, but with the lighting available (and using an f/8 lens/TC combo) I needed the 3200 to get the shot!

The first shot is cropped at about 50%, the second is full-frame:

That's interesting. I had a similar experience when I mounted my Tokina 11-16mm f/2.8 on my 5D Mk II to see how much vignetting I would get.

In DPP, the inside edge of the vignetty circle was very ugly, with a white ring and some white spots. In CS4/ACR, it was just a normal vignette - very useable if you wanted to leave it there.

If I get the time/energy, I might post that up.

Nice shots. That's something it took me a while to 'get' - how much light is really needed to get the image. A few months ago, if you would have asked me if ISO3200 is ever appropriate for a daylight shot in an open area, I would have said "no way" - as your example so clearly illustrates, our cameras like lots of energy going to the sensor in the form of light.

I've started shooting my 5D Mk II in AV mode with Auto ISO - and seeing that higher ISO's are needed in many shooting situations, not just the proverbial "low light".

Good examples, Tony.

Hey, thanks!

Gotta say, I was pushing it. They look nice and lit, but really it was late afternoon and dim light. Plus, I was stretching for focal length -- 100-400 at 400 + a 1.4x TC, so 560mm at f/8 means something has to give. My comfort level tends to be ISO 1600 and a 1/500 shutter speed, but when pushing things like this everything goes up in smoke!
