A Lot of Noise in DPP

[TomPhotog]

Canon 400 XTi
RAW
DPP

For pics I shot at ISO 1600, there is a lot of noise in them after DPP and default adjusting with the tool.

If I open Zoombrowser and look at the same pics, there is noise, but not to the same great extent there is in DPP. Especially bad is red dots.

What's up with this?

First: What version of DPP? The newest version (3.0.1) has pretty good noise reduction.
Second: Compare noise / sharpness at 100% between different programs.
Third: Exposed correctly? Underexposure and 'pulling up' in Raw conversion is a guarantee for noise...
Fourth: Raw has no NR done by default. Jpg has. Therefore a Raw can be sharper, a jpg has less noise.
Fifth: How much is "a lot?"
Here (http://www.moonglade.net/rene/POTN/ISO1600_0EV.jpg)is a screenshot of a 100% crop in ACR (with a bit of NR and sharpening in ACR) of an ISO 1600 shot with my 1D2...

Hi,
The version is 3.0.1.5. I have just started shooting RAW and using DPP so I'll have to get more experience and after I get more comfortable using and post processing with DPP I'll try comparing it to some other programs.

DPP has very good noise reduction than ACR

I think i know what your talking about Tom . . . its more like almost a red noise banding effect where small blobs of red seem to come through on the image.

I get this sometimes on when photos at high ISO are struggling to get a good exposure ... the reds just dont seem to quite have an even-ness to the noise and grain compared to the other colours . . . i came across this in some other threads on here I think ( i dont have a link to them ).

Its not something i've managed to get rid of in software... but it is something i am aware of when taking shots in dark situations . . . if possible when in those cases, i'll try to over expose slightly to try and eliminate it.

DPP v3.x simply stinks.

Noise reduction defaults cannot be specified, transfer to photoshop does not work under Vista at least, no fool-proof way of changing & controls of exposure changes. The list of blunders goes on and on. Hopefully Adobe will release ACR 4.1 later today and the nightmare ends...

Hi, I'm not sure if I applied noise reduction. I only got so far as to apply the default auto-tool correction.

Hi Don,
It didn't really seem to be in "bands", it was more like a sprinkling of noisy dots, mostly red dots.

I just thought of something that makes me wonder if it explains why the picture looked much less noisy in ZoomBrowser. (Decent instead of awful.) Does ZB open the picture as a jpg or some other file type than the RAW DPP is seeing, and maybe do some auto-processing or auto-correcting?

[Tee Why]

ZB can see RAW and JPEG files, I'm not sure but what quality setting for previewing images do you have set for ZB? That may be a factor.

Well, that's a matter of opinion. Granted, it has several flaws and shortcomings, but I for one prefer it over ACR anyday.

It took Adobe to buy Pixmantic in order to get ACR to finally work somewhat better as a raw converter. Now they give us Lightroom, which works great, gives us plenty more functionality, but at three times the cost of RawShooter? No thanks!

I'll stay with DPP and its flaws. I've yet to find ANY raw converter that gives me the output that DPP does with the same amount of effort. Lightroom can give me the output, but at three times the effort, and three times the cost of what was RawShooter. :rolleyes:

[René Damkot]

Agree 100%

Huh? Agreed Lightroom is expensive; but I thought it was supposed to require less effort to use than DPP because it was more efficient, more intuitive, had a better interface with more tools that were easier to access and it had easier batch processing etc. Am I missing something?

[René Damkot]

With some 'difficult' colors, DPP does better 'out of the box', while LR requires a lot of tweaking. Try shooting under stage lighting once, and you'll know what I mean...

Get Neat Image or Noise Ninja and run your high ISO pictures through that...

Compared to Neat Image (which is the one I like) the noise reduction in DPP is pathetic..and I like DPPP....LOL

I tried LR for the full 30 day trial period, and discovered that the above is generally true, with a healthy dose of Adobe hype. Yes, it is a very, very capable app, one that will surely get better with time.

But if your workflow can stand the shortcommings of DPP, you will get better output, in less time with DPP rather than with LR. Then, you won't be missing anything - especially $300 bucks. ;)

Yes, DPP's noise reduction is not up to par, but sometimes it's adequate. Enough so that sometimes you may not need another app. But if you do, there is a third option - Noiseware Pro. And they have a free "community edition" that works great, albeit w/o batch processing capability.

I just looked and I don't think there is one. I remember seeing one for DPP though, so I thought this may have been the issue. I think I'm wrong here.
