Canon 50D CS3 raw conversion noisier than DPP

The ACR CS3 raw conversion of Canon 50D files seems considerably noisier than conversion in Canon's own DPP converter. Is this correct, and are there plans to put it right?

ACR pretty much leaves the noise reduction up to you to configure the way you want it. The Canon software applies noise reduction automatically. I don't know if this noise issue has changed in later versions of ACR, but there won't be any more updates for your version. Have you downloaded the profiles that have been provided? Have you updated your ACR to version 4.6?

hallo from italy
I'm able to view and convert correctly all my raw previous file shoted with canon 450D. recently I buy a canon 50D but the aperture program show me a little image on preview and a warning message appair and tell me "unsupported file format"
i try to:
update my camera firmware
update aperture to 2.4 versione
update snow leopard 10.6.1
but nothing change.
when i try to import a raw file directly from my disk or my camera the little preview appair in centre of m desk and the warning message "unsupported file format" appair
I use currently Lightroom - PS cs3 and Canon Digital Poto Professional correctly with this files
do you have suggestions?
thanks in advance

CS3 raw conversion color shift

When using the RAW converter in CS3 there is a noticeable change in color from the RAW image to the converted image. I am using two Dell E228WFP monitors that have been calibrated and this allows me to see both images at the same time. I moved the images so they sat side by side on the same monitor and a difference in color was still evident.
I suspect something is happening in the conversion process and would appreciate any suggestion to correct this.
I am using a Dell Dimension 9200 with a VISTA operating system.
Thanks

What application is displaying the raw file, and which application is displaying the converted file?
If you are looking at the preview of the raw file in Camera Raw's dialog--which application is hosting the Camera Raw plugin at the time?

Canon DCS 520 RAW conversion

I have an archive of images taken with my old Canon DCS 520 camera. Aperture does not support the RAW format from this camera, yet Adobe Camera RAW 4.1 does.
What is the best way to convert these images so that I can bring them into Aperture an still make adjustments as if they were RAW files. Can they be converted to a DNG file? And if so how?
Any help greatly appreciated.

Sorry, answered my own question. Adobe's DNG converter handled the job perfectly and using the DNG file I can access RAW adjustments of my Canon DCS 520 files in Aperture 2.0.

Canon Powershot G1X RAW conversion

Altthough the G1X is not yet included in the Beta camera database, will it be included in the final Lightroom 4 release?

Unfortunately Adobe can't answer that now (by policy). Just have to wait and see.

Canon G9 and RAW: colors are different

Hi,
I tried to find an answer in this forum and on the web but had no success, though somebody must surely have noticed this before. I have a Canon G9 and when I import RAW images in Aperture 2 (2.1.3, with the latest updates), the colors look quite different from when I open the same RAW images with the Canon supplied software (Raw Image Task) or even with the Gimp. I am not even able to make the Aperture version resemble the Canon one by just changing white balance or other simple parameters, so it's not a trivial issue.
Did anybody face the same problem and found a solution?
thank you very much in advance for any suggestions,
cheers
giuseppe

Hi Andreas,
thank you very much for your reply. I guessed something like that was going on. The colors from the Canon (or Gimp) raw conversion are much closer to the original than the Aperture ones though, so this poses a problem: If I want to use the Canon or Gimp conversion but store the image in Aperture, then I have to export the RAW file as TIFF or JPG losing the benefits of non-destructive editing on RAW files in Aperture.
I wonder if there is any software which could re-save the RAW image with some additional information that could make Aperture read in the correct settings for the RAW conversion. At any rate, it seems a bit strange to me, to say the least, that while an open source software like Gimp (even Picasa, I just found out) is able to the do the correct conversion (comparing with the actual scene's color as my eyes see it) - as Canon's own software - a commercial professional product like Aperture can not.
What do people usually do in situations like this? I tried to reconstruct the same colors that Canon gives me but I cannot even get closer to it. I guess it should be possible to do it with a very detailed manipulation of the Levels, but that is just too much work to do for every image...
cheers and thanks again for your comments

CS3: HDR Merge Problem with Canon 50d RAW files

I recently upgraded from a 20D to a 50D. I'm running CS3 under WinXPpro with 3GB of RAM. HDR merge of 3 CR2 files is causing CS3 to generate a program error and crash. This never happened with my older (smaller) files from the 20D. Anybody know how to fix this?
TIA,

The suggestion was to try an HDR with smaller 50D sRAWs as an *experiment* to see if the size matters more than the camera model. Another benefit of a 50D would be the 14-bits per pixel instead of 12-bits and an sRAW would have less noise per pixel than a full-size RAW so using smaller sRAW images might work better than a 20D's.
The "size" being referred to is the dimensions in pixels, not the on-disk size, becasue the in-memory size of an image should be similar whether it comes from a 16-bit TIFF or an 16-bit RAW conversion.
Merging RAWs will involve ACR during the HDR process, whereas merging TIFFs won't unless you have the setting to prefer ACR for TIFFs, too, which you don't indicate.
There can be data in the highlights and especially shadows from a RAW that gets thrown away when it's converted to TIFF, so merging RAWs is better than merging from TIFFs.
I currently have CS4 only on my machine so I forget, but with CS3, does it matter what output size you have set in ACR, when you do an HDR conversion from RAW? In other words, does HDR using ACR ignore the output size or not? If not, then perhaps setting a smaller size in ACR (the same area where you set the bit depth and conversion colorspace) would make things work or setting a larger size with 20D images would make them fail. This is being suggested as a experiment as well, to try to isolate the issue, not necessarily a permanent solution.
I don't think there is anything inherently wrong with a 50D RAW that would make it not work, but the larger size would use more memory and maybe your machine is getting close to some sort of limit.
Other suggestions would be to reset your preferences and check your disk(s) with scandisk and/or change your scratch-disk to somewhere else to make sure there's no some corruption keeping the HDR process from working with the larger 50D images, and along those lines, also try purging your ACR cache or moving it to another drive. You might also try changing the amount of memory available to Photoshop (ram vs scratch-disk) in the Preferences.
What module does the crash occur in, if the error says? Is it related to display or something else?

Raw conversion to JPG better with DPP than ARC 5.X

I started testing conversion from raw to jpg with Canon's Digital Photo Professional and ARC 5.x (CS4) and noticed a much better conversion with DPP. At low ISOs does I don't see much difference, however at 800+ it is very noticeable. I hate to give up the work flow of Bridge and ACR and go back to using DPP. Is there anything that can be done to improve this?

Quoting from an old post of mine, with apologies to all who have read it before:
This has been covered ad nauseam here. Please do a forum search for more details.
Camera manufacturers, Canon and Nikon in particular, perform in-camera RAW to JPEG conversions designed to generate the over-saturated, over-contrasty and over-sharpened images that appeal to most amateurs.
Their stand-alone RAW conversion software also performs the same conversion to your RAW images.
Noise is also hidden by compressing the shadows so you don't see much of the noise inherent in the image.
Adobe Camera Raw, ACR, on the other hand, comes with default settings designed to give you the most detail possible
(even if this sometimes means revealing some of the noise hidden by the camera manufacturers in their RAW conversion software), as well as the most natural images.
That being said, you can calibrate your camera to ACR and come up with your own settings to produce exactly what you want, including the JPEG-look of the camera manufacturer, and save that as your profile.
The key is to learn how to use ACR properly and to calibrate your camera to ACR.
The camera calibration refines the settings by letting you adjust for the exact sensor response of your individual camera unit rather than the average of a sampling of such unites provided by Adobe.
The ACR defaults are nothing more than a suggested starting point.
The color temperature won't necessarily match either.

Raw 2.3 update & Canon 50D

I was glad to see support for the 50D added with this new update, but after some quick testing I am disappointed with Apples conversion on pictures taken at 800 iso or faster compared to DPP. Aperture shows a lot more noise at the faster ASA settings. Adobe Camera Raw has the same problem, so maybe DPP is performing some kind of vodoo on the higher speed settings that Adobe and Apple have not (or cannot) figure out.
Has anyone tried different settings within Apterture to try to replicate the output that DPP is able to achieve at these higher iso's? I quickly tried a few things without any success. When I get time I will delve into it further, but if anyone else has some ideas of how to get similar results, I would greatly appreciate any tips or suggestions. It may be that Apple just needs to fine tune the conversion for the higher iso's, but it seems as though no one else has reverse engineered what Canon is doing.

Not using a canon 50d, using a Sony a900 instead. Actually, DPP is special because it does absolutely no noise reduction (at least in AHD mode). You can see that it is actually noisier but with a much finer grain pattern than ACR, aperture, raw developer, etc. You don't get the blotchiness associated with the NR of these other converters. The beauty of this is that when you run it through your grain reducing software it is much better for the software to deal with (the noise hasn't been processed by any NR software- which makes the noise non-random) and as such produces much cleaner images. I just did a comparison of the noise with the A900... here are links of the comparison using a publicly available Imaging Resource Raw file:

Aperture doesn't do a bad job, better than most others, but still not as good as RPP.

Canon 50D Raw & Viewers

Do any viewers exist (similar to the Epson P-6000) that are able to display
raw files from a Canon 50D?
Thanks
Mike

One option might be something like FastStone running on a (Windows) netbook. A bit larger than the Epson, but far more flexible and probably cheaper. Watch out for the poor battery life on some netbooks, though.
FastStone defaults to showing the embedded JPEG from raw files, so it's very quick and lightweight. I don't know if it's been updated to support showing the actual raw pixels from a 50D yet.

Awful canon raw conversion for photos with dramatic (i.e. underwater) non-standard white balance

I'm shooting underwater (and white balancing as I shoot using a white disc) with a canon s90, and have noticed that the raw conversions done by aperture are way worse than those from jpegs when I shoot in raw+jpeg and those done by raw processing using the canon digital photo professional software. In particular, reds are pretty much lost. It may be a false lead, but I notice that in aperture, the rgb histogram shows a dramatic spike of the red channel on the far right (possibly clipping?) that doesn't show up in the rgb histogram in the canon software.
I'm not sure whether this is related to the plethora of threads about canon raw processing and overly green output. Has anyone else experienced this or have any ideas? I could batch convert to tiff in the canon software but I'd really rather not do that... For one thing the 16bit tiff files are so much bigger than the raws and it is an annoying extra step. Also, note that I can't just batch fix the white balance because (a) I'm having a hard time getting aperture to do it properly (possibly b/c the red channel is clipped as far as the aperture UI is concerned?) and (b) The white-balance changes from picture to picture as I change depth, which is the whole reason I white-balance as I'm shooting in the first place..
I've attached two versions of a picture, one of which I processed the raw in aperture and one of which I processed the raw (and converted to TIFF to give to aperture) in the canon software. I then exported both as small jpegs from aperture.
Canon Digital Photo Professional (correct):
Aperture RAW processing (very wrong):

>Is MS Picture Viewer a colour managed application? I don't know, but don't think so. Lightroom is however which might be the cause of your problems.
Not in XP. In vista it is color managed. From the sound of it, the problem is a bad monitor profile but you might also have a corrupt Lightroom database. You need to recalibrate the monitor and NEVER use canned profiles from the monitor manufacturer. They are almost always corrupt. As a very last resort, you can use sRGB as the monitor profile (delete any profile found in the windows display properties) but only to hold you over until you can really calibrate it. The other problems with weird errors are pretty worrisome though. Do you also get them when you start a fresh catalog?

Trouble importing RAW from Canon 50D to Lightroom 3.3

I've searched the forum and can't find much reference to this -- I shoot with a Canon 50 in RAW format only. When I attempt to import from the camera (File -> Import Photos then select Canon EOS 50D as source) into lightroom 3.3 (same with 3.1, 3.2), no photos appear in the import window.
As an experiment, when I changed the format to JPEG, the JPEG photos appeared in the dialog as I would expect.
My operating system is Windows 7 64 and I am using Lightroom 3.3 64-bit version. In the help menu under the version is says "Camera Raw 6.3" On the 50D the Raw format is set to "Raw" rather than S-Raw-1 or S-Raw-2.
I am able to import the photos by importing through the Canon utility and then importing those photos into Lightroom.
Any help you can give would be appreciated. File management is starting to become an issue.
Thanks

Thanks for the replies.
First, I don't have a card reader and yes, I probably should get one eventually. To clarify, import is not slow, it simply does not even attempt to import. When I connect my 50D with a card full of RAW files, LR detects it but it shows "No Photos Found." I honestly don't think that it is LR's fault, it really seems like there is some obvious setting I have missed on either my camera or LR.
Thanks.

Lightroom 1.4 & Camera Raw 1.4.1 & Canon 50D raw images

I am about to test a Canon 50D in conjunction with a Canon 20D.
Will I be able to work with the 50D raw files with my version of lightroom?
I have not moved to Version 2 lightromm because of the many reports about it's slugish performance.
Your help would be appreciated.
Roy Palmer

All you have to do is make sure that you are always using the very latest version of the DNG converter. Yes, the very latest. It is not necessary to match the DNG version with the ACR/Lightroom version.
When I use the DNG converter, I usually open the card in Windows Explorer, highlight all of the images, then drag them onto the icon for the DNG converter. The converter starts, I specify where I want the files to be placed, and then click on the Convert button. That's really all there is to it. Yes, it takes a few seconds for the DNG converter to convert the images. But it's really as simple as a download.

Canon 50D RAW files not showing

Hi all,
I just got a Canon 50D as an addition to the current 400D (Rebel in the USA).
I am shooting 100% RAW files, and I am having a problem with previewing them.
I downloaded and installed the Camera RAW 5.2 fro Adobe and Lightroom and Photoshop have no problems opening the files.
The quick view show only a white (generic) icon, Preview a Question mark, while the RAWs from 400D show without a problem.
I can sort of live with it as I use Lightoom for all viewing and editing, but it is a bit annoying that a quick look with the Quick Look is impossible.
Anyone has /had this issue? Any solutions please?
i.3d
OK, here's a boy who answers his own questions...
The Apple Camera RAW update 2.4 does NOT list 50D as a new supported camera model, and yet... what do you know... it does include support for Canon 50D.
Done!
Hope it helps someone.

As to the Adobe RAW, I thought that it also becomes a "system extension" (for the lack of a better wording) which COULD help, and which obviously doesn't. Thanks for the info.
In regards to the Apple Update, I just assumed that the latest would contain all previous updates, or if it did not, upon install inform that one needs the previous one installed first (Just like Java updates do) - which, again, obviously it doesn't. Again, thanks for the info and the link. I am downloading as I type this, so will see soon - after a restart, so an edit is coming...
Strange thing with the yesterday's RAWs working 100% and today's not at all.
Hopefully the 2.3 will do the trick.
Stand by.
We have a problem, the 2.3 tells me that it DOES NOT NEED to be installed as a newer version is already installed. This would imply that previous updates are indeed included in 2.4 (just like the security updates - enough to install the latest one.
Well, that's a bit of a problem, innit?
Any way to manually pick the 2.4 off the system?

Canon 50D RAW: LR2.1 RC1 vs. ACR 4.6

Will the RAW processing of a Canon 50D file be identical between LR2.1 RC1 and ACR 4.6?
I ask because I want to do apples-to-apples comparison of high-ISO images from the 40D and the 50D. I'd prefer to process the images in LR, but only if LR is just as good as the latest version of ACR in processing images from the 50D.

>Will the RAW processing of a Canon 50D file be identical between LR2.1 RC1 and ACR 4.6?
No. It will be identical between LR 2.1 FINAL (not yet released) and ACR 4.6 FINAL (just released).
