Download Canon 7D DNG color profiles

Hello everyone!
I just got a new Canon 7D and I got to say, when I open my photos (I shoot in raw) in Lightroom they don't exactly look like what I see on the back of the camera...so I'm looking for color profiles that would match the 7D's colors but I'm not sure where to look for them.
So my question is, where can I fin Canon color profiles to download?
Thanks for your time!

There is a profile creator provided by Adobe to create specific profiles for your camera in LR/ACR other than that I do non believe there is any option to just stick profiles into LR/ACR.

Problem with DNG Color Profiles in Lightroom 5.4

Hello folks,
I recently updated from LR 5.3 to Lightroom 5.4 and since then I am having problem when using dng color profiles which were created with Colorchecker Passport. Every time I use such a profile which was created for my Nikon D 800 I get very greenish tones in the pictures.
I use Windows 7 Pro on a HP Z 210 Workstation. The monitor is a hardware-calibrated Quato which was recently calibrated.
Does anyone have this problem too and - if yes - know how to fix it?
Thanks!
Yours, Albert
PS: As English isn't my mother tongue I apologize for any mistakes in the text above.

Hello Andrew,
I do have a Nikon D 800 and a Fuji X-E1. I haven's noticed a problem with the Fuji so far. I think I will recalibrate my monitor tomorrow and see if the problem still exists.
I can supply raws and DNG profiles but I don't know where I should upload them - I suggest I could do it on my own webspace. Would that be ok?

Canon 5d2 DNG +custom profiles = bad preview in Bridge?

I'm using DNG Profile Editor (1.0.0.39 Beta 2) to make custom profiles for my new Canon 5D Mark II, and then using DNG Converter (5.2) plus Photoshop CS3 Bridge to process images. All on Windows XP.
After my 5D2 custom profiles were in place I noticed that the image preview in Bridge CS3 was "bad." The Bridge preview is very blurry and does not update when changes are made to the DNG file via ACR. For example, if I change exposure in ACR and click "Done" or "Open in Photoshop, the change is saved OK in the DNG file but the Bridge preview remains the original blurry image.
Took a long time to figure this out because I did not immediately associate the problem with the creation of custom profiles. Older 5D2 DNG files previewed OK in Bridge, as did DNG files from my other cameras. I even re-converted some old camera raw files to DNG and they previewed OK in Bridge. There are custom profiles in place for those older cameras.
I spent a lot of time on the usual suspects - purging cache, reseting preferences. All to no avail. Then I removed all my custom profiles and deleted the index.dat file. Ran DNG converter again to make new DNG files from the 5D2 raw. Now the Bridge preview was OK. Then I restored my custom profiles and converted raw to DNG again, getting bad Bridge previews again. Yet the previous converted files would still preview OK in Bridge.
My conclusion: The DNG converter is using camera profiles during the conversion, and in the case of 5D Mark II raw files is creating an error. I'm guessing it is putting an embedded jpeg in the DNG file that somehow confuses Bridge.
I've repeated the tests many times now. I've changed the DNG Converter "jpeg preview" preference to none, medium and full. For the 5D2 files I get bad Bridge previews on all settings. But I get good Bridge previews on my Canon 20D and Canon 1Ds DNG files regardless of any settings. Regardless of the presence or absence of custom profiles, regardless of the jpeg preview size, regardless of the ACR default settings.
So I'm hoping the Adobe team can take a look at this. Or anyone willing to confirm or deny my tests. I don't have an easy way to post a DNG file, but could email one of my "bad" ones to anyone willing to take a look.

The lack of response to this post forced me to keep testing. Now I've more closely pinpointed the problem and found an easy work around. First some background.
ACR camera profiles are stored in two places. The Adobe supplied profiles are in:
C:\Documents and Settings\All Users\Application Data\Adobe\CameraRaw\CameraProfiles
and your custom profiles are in:
C:\Documents and Settings\yourusername\Application Data\Adobe\CameraRaw\CameraProfiles
Adobe Camera Raw, and it turns out the DNG Converter, both build an Index.dat file in this last folder. Apparently this index is built by scanning both camera profile directory trees and building a list of all the profiles it finds. It then sorts that list alphabetically by the profile name that is embedded in the file, not the Windows file name.
The "Adobe Standard" profile for a camera has a file name like "Canon EOS 5D Mark II Adobe Standard.dcp", but embedded in that file is the profile name of just "Adobe Standard". That's why only "Adobe Standard" shows up in the drop down list of profiles in ACR. And that's why "Adobe Standard" appears before "Camera Faithful", which appears before "Camera Landscape". It's alphabetical order.
Now, when you create a custom profile with the DNG Profile Editor, the "Export" function puts "Canon EOS 5D Mark II" on the front of the name. If you are an idiot, like me, you type over all that with something simple like "5D2 Bouce Flash" for the profile name. But wait, "5D2 Bounce Flash" sorts alphabetically before "Adobe Standard" and appears first in the ACR drop down menu. Sounds OK so far.
But then the magic occurs. The DNG converter uses the camera profiles. It actually accesses that Index.dat file, and if it does not exist, the DNG converter will rebuild it, just like ACR. Why it does that I can't imagine. Seems to me that the DNG converter should be simply converting raw to DNG and passing the EXIF and embedded camera jpeg along as is. What need does it have for camera profiles?
Anyhow, if that 5D2 profile is first in the list due to its alpahbetical name, the resulting DNG file will confuse Bridge. Bridge will display a fuzzy preview and will never update that preview, or the thumbnail, when you make adjustments in ACR.
But if you name the 5D2 custom profile such that it sorts alphabetically after "Adobe Standard", then all is OK. The DNG files can be previewed and thumbed OK by Bridge. So I named my custom profile "My 5D2 Bounce Flash", a simple workaround.
Now I can move on to more important things. Like generating a good custom profile for the 5D2. So far the Adobe Standard profile beats anything I've generated. Especailly if I remove that curious Point Curve which can sometimes muck up the shadows.
And now that Bridge previews are "OK" I can work on the mystery of why Bridge Previews of 5D2 DNG files do not match the previews of their equivalent TIF or PSD files. If you're curious you can see samples and read more about that here: http://forums.dpreview.com/forums/read.asp?forum=1032&message=30748423

Sigma DP2 - no dng color profiles available, only embedded

Converting X3F raw files from the Sigma DP2 a color profile created with the X-Rite Colorchecker Passport doesn't show up in the panel Camera Calibration. Instead custom profiles created for Canon cr2 raw files from a Canon 5D are showing up when working with Canon raw files.
Is this a bug of Lightroom?

Wow, I'm so glad Eric Chan is in this problem... unfortunately it's not the only one :
There is the fact that processing is locked to black and white when the white balance was set to black and white in Sigma Photo Pro (even if the color data is still there).
I know SPP writes in the files, it's bad, but Nikon's Capture NX does it and it doesn't change the way NEFs are treated in lightroom (or at least not to such extent).
Better default profiles for the sigma cameras would be a major plus too.
Take a look here for more (WB problem and bad default profiles) : http://forums.adobe.com/thread/629739?tstart=0

Photo Downloader modifying embedded color profiles

When downloading files from a camera, Photo Downloader apparently modifies embedded color profiles. Even those pictures that had been shot using AdobeRGB have their profile replaced by some profile called "Camera RGB"... whatever that is.
Does Photo Downloader actually
b convert
to this profile or does it just
b assign
it?
Anyway, is there a way to prevent Photo Downloader from modifying embedded profiles?
Thanks!

This excerpt is from a long-gone post by the late, lamented author Bruce Fraser:
Bruce Fraser - 4:17pm Jun 14, 04 PST (#5 of 21)
Opening files directly from the camera is a bad idea for a variety of reasons*, and it most certainly isn't faster than using a FireWire or USB2 card reader.
         Drains the camera battery
         Runs the risk of the software you're using to open the images writing to the card and destroying the format
         Runs a small but significant risk of USB power frying the camera
         Slowest method known to mankind of getting images off a CF or SD card

Where to find color profile for Nikon D80? Then how do I apply it?

I've tried googling and found a few places that claim to have ICC profiles for my Nikon D80. I've seen people say, "oh use program X or Y to apply it" but I want to do everything in Photoshop (CS6, on my Mac running Yosemite). Can someone point me at a place to find an ICC profile so I can get my Nikon NEF raw images into CS6?
Can you further tell me how to install the profile? I've tried all three locations described at Introduction to Icc Profiles and I've rebooted many times. No luck! The ICC files I've got look find but maybe they aren't?

Lightroom doesn’t use ICC profiles, it uses .dcp files, DNG Color Profiles. The profiles come with Photoshop and updates to the Adobe Camera Raw (ACR) plug-in.
If you really mean the D80, then that has been supported since PS-CS2/ACR 3.4.
If D80 is a typo and you meant D800, then that has been supported since PS-CS5/ACR6.7.
If D80 is a typo and you meant D810, then that has been supported since PS-CS6-or-CC/ACR 8.6.
Do About Plug-ins / Camera Raw and see what precise version you have, and verify which camera model you have.

Converting RGB to DNG without affecting color profiles

Hi guys
I'm working with the DNG SDK in C++ for some time now. I need to be able to take a raw RGB (not camera raw) and convert it into a dng file. After playing arond with it for a few days, I realized creating the camera profile drastically affects the resulting dng image.
I can't seem to produce a dng file that was identical to the input source. My picture appears very washed out and I end up using the adobe color profiler to try to bring the image back close to it's original color.
I'm trying to find a way to produce dng files without the need to affect the colors in any way, the resulting picture should be bit identical to that of the raw RGB input file.
I'm not even sure if I can do this considering the usage of the dng format.
UPDATE
I've realized that my program is loading the RGB buffer into the fData of the stage3 image object. I have a feeling I need stages1 and 2 but i'm unsure if I need to and if so, then i will probaby need a source DNG to produce those stage1 and stage2 unless I can get stage1 or 2 from stage 3 (appears it works vice versa).
I'm able to do the reverse (DNG to RGB raw) by extracting the buffer from the stage3 render. but in this case, all the metadata has been filled in by the input DNG. However, going from RGB to DNG, I don't have the metadata to fill into stage 1 and 2.

My understanding of the JPG is only middling. I thought I understood that it uses anchor pixels and either a translation table of some sort or difference mapping, using 8 bits per piece of information.
If that were the case, surely changing the translation from CMYK to RGB would be fairly simple.
In this case, the usage is Ebay and they only accept JPG, PNG (and maybe BMP and GIF, I didn't look that closely), but require RGB. I was actually quite surprised to find that JPG allows CMYK since, as you say, anyone dealing with CMYK is going to be dealing with commercial printing and few people who deal with commercial printing would play around with JPG.
I always stick to TIFF or PSD for workflow, but JPG is popular for a reason - when it comes to web, JPG is the only format that can deliver manageable file sizes with full-screen or "large" images for web. Our top level banner photo is 2590x692 and needs to be under 400kb for sane download speeds. PNG couldn't touch that. Even with the aforementioned 1800x1200, PNG is nearly 2mb, while I can maintain very decent quality with a 500kb file with JPG that works well for 'zoom in' type usage.
So there's no way around JPG. It's just annoying that the first person to touch a random selection of the pics was primarily an Illustrator user and saved *some* of the pics in CMYK mode.
It's like that old story about the farmer who didn't want anyone to steal his watermelons, so he cleverly posted a sign "None of these watermelons are poisoned", only to find a note the next day saying "Now, One of these watermelons is...".
Far more work to fix 'some' of the images compared to just doing it right the first time.
But then again, for workers like that, if you can't trust them with an easy job, you could hardly trust them with more complicated jobs...

DNG converter converts RAW Adobe RGB color profile to ProPhoto ??

I have a Canon 5D2. there is an internal switch to shoot RAW files using the Adobe RGB profile. when I open a RAW image in CS4, there is no problem. yet when I open the DNG converted image in CS4, CS4 tells me the image has the ProPhoto color profile. I can convert back to Adobe RGB, but it adds an extra step and (I think probably) loses information. I looked for a switch in the DNG converter to speciy the color profile of the converted image, but could not find it. Any suggestions ?

Hi, Tom.
The real issue here is getting accurate color. You can't get accurate color by setting your monitor profile to sRGB. sRGB is a virtual color space that doesn't describe the exact color gamut of any physical device. But, in order to display sRGB or any color space accurately, you need to get a characterization of your monitor.
Here is an AWESOME way to get access to a colorimeter: http://www.lensrentals.com/rent/pantone-huey-colorimeter Looks like for $32 you can rent this for a week. Go in on this with a friend and profile both of your monitors and hardly pay a thing. If you have a reasonably good quality LCD monitor, this custom profile you make will be fairly accurate for many months. At the very least, this is way more accurate than having no regular calibration at all.
Hope this helps!

DNG files rendered with wrong color profile?

Does someone else also have a problem with DNG (digital negative) files showing incorrect colors when opened in Apple software (Preview, iPhoto, Aperture..)?
I have a Nikon D750 and currently consider using DNG as archive format for my RAW files.
But the converted DNG files are shown with a wrong color profile when opened via Apple's own camera raw framework...
It works in Adobe software - such as Lightroom - but any software using the OS X internal camera raw framework seems to use the wrong color profile when opening the DNG. Note that the original D750 NEF files are opened and rendered correctly.
I am using OS X Yosemite 10.10.2 with the latest Camera Raw Compatibility Update 6.02 installed.
On the Adobe side, it is Lightroom 5.7 and DNG Converter 8.7.1.
I tried all kinds of different conversion settings. It does not seem to make a difference whether I embed preview images in the DNG or not, whether I shoot in 12 or 14bit RAW, and whether I include the original RAW file into the DNG or not. I also tried to explicitly select the 'Camera Standard' color profile in Lightroom first and then export the DNG, but still on the OS X side the resulting image looks wrong as compared to the original NEF.
Any other Nikon user here who could verify my problems?

A few simple tests on your end may help you better understand:
1. Capture the same image (same camera settings in RAW and JPEG)
2. Open these images in Canon DPP - they will be a close match, this is because Canon DPP and the Canon camera itself use similar RAW processing algorithms
3. Open convert the CR2 to DNG, and open the CR2, DNG, and JPEG in Adobe Camera RAW - the CR2 and DNG should be a very close (if not identical) match if you use the same processing settings for each, since they are both being processed by ACR's algorithms; the JPEG will probably not match as it was processed with Canon's algorithms
What you are seeing is at the HEART of raw processing, and has nothing to do with color spaces or with DNG being at fault. The very nature of RAW processing means every processor (DPP, ACR, CaptureOne, etc) will produce different results by default - that's not to say that with some adjustments you can't match one processor's results to another, but it won't be the case by default.
The choice of RAW processor has FAR more an impact on your results than color space - in fact color space should have virtually no visual impact, though depending on the scene photographed you might have better gradations in some color spaces, better handling of highly saturated colors in some, but the overall look should remain close regardless of color space choice.
Further, as has been pointed out by others, raw files (which includes CR2 and DNG) do not have a color space - raw files are by definition raw image data which has yet to be processed into a color space. When you see color space assignments in RAW processors, that is relevant to the files you create FROM the raw files, not relevant to the raws themselves.
Before bringing inflammatory language and false assumptions to a forum with a high level of expert membership you might want to research the issue, and devise some simple tests (like above) to help you understand the issue first.

I bought a canon EOS Rebel T5i. It came with photoshop elements 11. PS won't open my C2 raw files and says my camera isn't supported by the software I have downloaded 7.4 dng converter and I still can't open the files. What do I need to do?

You need camera raw 8.4 for your camera, if it’s Digital Rebel T5 EOS 1200D EOS Kiss X70. It is not compatible with PSE11; so it’s a bit odd if that software was bundled with the camera except that it will work with jpegs. I suggest you download and install the free Adobe DNG converter to convert your CR2 files to the Adobe universal Raw format and the DNG files will editable in PSE11(keep your originals as backups and for use in the camera manufactures software)
Mac download (.dmg file) click here DNG Converter 8.4
You can convert a whole folder of raw images in one click. See this quick video tutorial:

DNG editor color profile

I have created color profiles in the DNG Profile Editor, saved the recipe and exported the recipe to
C:\Documents and Settings\Dan\ApplicationData\Adobe\CameraRaw\CameraProfiles
When I go to the calibration tab in Lightroom, these profiles do not show.
Using Windows XP.
Thanks for any suggestions as to what I am doing incorrectly.
Dan

Dan,
It should work, it does for me.
Are the cameras supported by LR? You say there is a separate profile for each and I guess you mean these are existing in LR. If I am correct then it should work and I am out of ideas.
Just thought of one other thing. You could try putting your new profile into the existing file folder for your camera type. You should find the folder here:
C:\Documents and Settings\All Users\Application Data\Adobe\CameraRaw\CameraProfiles\Camera

Removing color profile (if any) from over-exposed Canon 5D mov file's

I am working with some footage from a cameraman's Canon 5D, they are in mov format, but I am having a problem when I import them to FCP (they look the same way when I play them in QT too).
The color saturation is extremely high, and I know it was not filmed that way on set, I want to know if there is some color profile in the mov files that Canon 5D's record and if so how do I remove them?
Basically everything looks way over-exposed and I know the 5D is not that poor of quality.

Below is the FCP info from one of the video files:
It appearently uses the h.264 codec for the video stream.
I know that the picture was not over saturated during the shoot because we reviewed it then on set, but now it looks different.
I even put both my arms on my camera guy's shoulder and looked him square in the eyes and told him that "the Canon 5D has a reputation for being over-exposed and over-saturated, I want under-exposed, make sure you pay attention to that and review every shot". (don't worry I was being nice to him, we're friends).
I should mention one more thing, when I place the video in a sequence on FCP's timeline, sometimes when I apply affects to it and forget to render it, there is a moment when the video looks properly exposed and then goes back to looking over-exposed when I quickly run the scrubber over it and not let FCP a chance to display properly.
So I know, or at least have reason to believe there is a color profile in there somewhere that is causing it to look over-exposed and over-saturated. I just can't get rid of it.

Embedded Color Profile is Lost When Content is Published to Web or Dragging Image Window on Desktop

Hello, Everyone. I have a question that I have struggled to crack on my own to no avail. I hope someone here can help.
I am trying to publish some images to the web using color corrected monitors, RAW format, and a color checker passport to create a perfeect color profile. Here are the technical details and my workflow.
Camera: Canon Rebel EOS Xsi
Format: RAW + L
Color Space: sRGB
Color Checker: X-Rite ColorChecker Passport
Monitor Calibrator: Spyder4 Pro, fully updated software
Computer: Lenovo T420 ThinkPad
Second monitor: Samsung LED SyncMaster SA350 (NVIDIA)
Photoshop: v12.1 x64 (CS5.5)
Photoshop Color Settings: Custom North America Web/Internet
RGB: sRGB IEC61966-2.1
CMYK: U.S. Web Coated (SWOP) v2
Gray: Gray GAmma 2.2
Spot: Dot Grain 20%
Policies
RGB: Preserve Embedded Profiles
CMYK: Preserve Embedded Profiles
Gray: Preserve Embedded Profiles
After importing the image into Photoshop, I make sure the RAW space is set to sRGB IEC6 1966-2.1
Use the eyedropper to select a neutral color one step away from pure white on the RAW image of the color checker, create and set the custom white balance.
set the white balance
Export the image as a DNG
Load the DNG into the X-Rite ColorChecker Passport software to create a color profile
Back to Photoshop
Open the RAW file
Set the white balance to the custom profile created above
Set the color profile created with X-Rite
Open the color-corrected image in Photoshop (see color setting above)
Save as JPEG
Publish
First, everything seems to go great throughout this entire process, until I see the image on the Web: LINK. Once published, the image has a very noticible golden-yellow tint to it. The color-corrected image looks great on both color-calibrated monitors, in RAW and JPEG. Absolutely perfect. After noticing the ugly yellow tint in the image I posted to the Web, however, I became aware of a couple more weird things.
1) When the JPEG was open in Photoshop and I moved the window that contained the image around on my second monitor, the image immediately took on that golden-yellow tint: you can see a screen shot of the color corrected image on my Samsung (bottom) and the yellow version of the same image created when I drag the window around on the Samsung (top) HERE.
2) When opening the X-Rite software, I got a warning saying that the laptop monitor had been calibrated, but that the Samsung had not. I got this error even if I calibrated the Samsung monitor right before using X-Rite. Also, the monitor is definitely calibrated, because the images look great, and the colors match what I see on the laptop.
3) Recently, I noticed that when waking my computer from sleep, the Samsung monitor no longer holds its Datacolor (Spyder4) calibration.
I thought the problem I was having might be due to the monitor, for the reasons stated above. However, I later noticed that when I open the color-corrected JPEG with the default Windows image viewer, it retains the color correction settings. The image looks fantastic, and doesn't lose it's color profile when I drag the window around. Also, there seems to be less color loss in the Word documents and PDFs I included this image in: LINK.
I checked this with several more images, and the results are the exact same. I scoured the Web as best I could, but my problem seems to be pretty unique. Does anyone have an idea what might be causing this?
Thank you!

Thank you, twenty_one, for taking the time to read my post and put up a reply. I am going to rebuild my question and post it again here. But first, to answer some of your points:
1. A raw file has no color space, until it's opened into one in the raw converter. So this is controlled in ACR, not the camera.
I just wanted to be as thorough as possible. One of the steps I took was to set the Color Space setting in my camera to sRGB:
2. White balance has no bearing whatsoever on camera profiles. A profile is not for white balancing, it's to account for the spectral distribution of the light, which is something else. You make the profile and assign it in ACR, then you white balance for processing.
I know. I wasn't talking about white balance in my camera. I set the white balance here:
I grabbed the color for setting the WB here:
3. If you get a message about monitor calibration upon opening the camera calibration software, something is seriously confused. The two have nothing to do with each other. No relation whatsoever.
Camera calibration software?
4. A corrupted monitor profile will only show up in Photoshop and other color managed software. Other applications that are not color managed will not use the profile and are not affected. So find out which apps are and which aren't before drawing any conclusions.
Agreed. That's partly what I am trying to get help with.
5. Your links don't work, and in any case clicking on links is something most people including myself dislike. It's much better to insert screenshots in the post, by using the camera icon in the reply box.
I'm new to this forum, so this is helpful to know. This image shows the color-corrected image (bottom) on my Samsung. It looks exactly the same in the same window on my laptop monitor. When I move that window around on my Samsung screen, it turns gold (top). The image, when posted to the web, looks *similar* to that gold color.
So let's say I only use Photoshop on my laptop, which is not displaying any colors. Do you think the golden hue problem will go away?

How to adjust the color profile on Macbook Pro/IMAC for Brother printers?

Hi,
We have both iMACs and MacbookPro w/Leopard 10.5.4 in our office. They also run the Parallels software with Windows XP. We have 2 color printers in the office, a Canon and a Brother 4070cdw. When I make a color print, the output looks very different from the 2 printers. The Brother printer produce very light copies, almost look like there's a white wash over it. I called Brother and went through all kinds of test and they finally said it's not the printer, but the color setting on the Mac. I didn't believe them at first, but then i did a test. I print a color page from the WindowsXP side on my Mac, and print the same page from the Mac side, and the results are very surprising. They look very different, like from 2 different printers; again, the one form MAc is very light.
I then opened up "system perferences" and tried to play around with the different color profiles under "Display". But the changes did not affect the print outcome much. Please help. Thank you very much.

To prepare a computer for sale or donation, in addition to the steps mentioned in this support article, take these steps:
If you set a firmware password, remove it by running Firmware Password Utility in Recovery mode.
If you activated FileVault in OS X 10.7 or later, turn it off.
If you use Boot Camp, the partition must be deleted
If you created any other data partitions on the internal drive, remove them in Disk Utility.
Erase the data partition(s) with the option to zero out data. An SSD doesn't need to be zeroed.
You can't legally or practically transfer any software downloaded from the Mac App Store to the new owner of the machine, even if it was free. That includes OS X, so if you paid for an upgrade OS X 10.7 or later, you must reinstall the original OS, either from the installation media, if applicable, or by booting into Internet Recovery (option-command-R at the startup chime.)
The new owner will have to repurchase the software, if need be, under his or her Apple ID. If you ever updated the bundled iLife applications (Garage Band, iMovie, and iPhoto) through the App Store, you can't transfer them either.
Remove the machine from your list of registered products. If it's still covered by an AppleCare Protection Plan, transfer the coverage to the new owner by following the instructions in the AppleCare Terms and Conditions (under the heading "Transfer of Plan.")

ColorChecker Passport-Color Profiles

Hi there,
I am photographing paintings with Elinchrom flashes with an even light and I use the ColorChecker Passport from X-Rite to keep a reference in order to match the colors.
Till now, I've been using the software DNG profile manager, provided with the ColorChecker Passport from X-Rite, which creates a camera profile that should be helpfull to get the right color. Once I've applied the new camera profile (after restarting lightroom), I do the white balance. It's recommended on the X-Rite tutorial to use the target number 20 called "neutral 8" to do the white balance. I've also tried the target 22 called "neutral 5", and it seems to get slightly better results.
I've noticed that even creating a color profile and doing the white balance the colors don't match. I am using a mac laptop screen that I calibrate quite often, which is not very helpful for obvious reasons, but that helps to keep track of the general look of the image, so that's why I keep the color adjustment to the RGB numbers.
I've downloaded the following PDF; here there is some information about the RGB values of various ColorChekers:
http://www.google.com/url?sa=t&source=web&cd=2&ved=0CB4QFjAB&url=http%3A%2F%2Fwww.babelcol or.com%2Fdownload%2FRGB%2520Coordinates%2520of%2520the%2520Macbeth%2520ColorChecker.pdf&rc t=j&q=ColorChecker%20rgb%20values&ei=wOCdTbG7NIyDhQelj5G8BA&usg=AFQjCNGj3wUpWC_uMxgMCeR3GI yN7kDU0A&sig2=mPf1grSAULxyMs_SanYVNw&cad=rja
Using these values and a selective color layer in photoshop I get close to the real colors, although it is not good enough.
My questions are:
1-Does anybody know the ColorChecker Passport RGB (Adobe 98) values?
2-I've tried to use the DNG profile editor because it seems a precise tool for this, but it doesn't recognise the 5D Mark II files. Is it because this application hasn't been updated? It also seems to work only with 6500K or 2850K, which is not the case of the Elincrhom 600 monoblocks I am using (which I think are around 5000K.
3-Could anybody recommend a workflow that's better to match the colors?
I have more questions, but I think these three are a good start.
Thanks!

Here are color-error analysis plots for several camera calibrations using the fine-art color-checker calibration shot uploaded, earlier.
The three profiles tested were:
1) A custom Elinchrom Flash profile I created from the color-checker using the DNG Profile Editor,
2) The Adobe Standard camera profile,
3) The custom profile provided by Gustov.
My general comment would be that the Adobe Standard profile has about the same error as the custom profile I computed using the DNG Profile Editor but the Adobe profile has a more even distribution of the color error.
The profile Gustov provided seems to be very close in the yellow area, but quite far off in the reds, blues, and violets. This can also be seen as a severe shift toward the green of the WB Tint slider value when the profile is selected for the As Shot WB as compared to the almost zero value when using the Adobe Standard profile.
These color-error plots were created using the ColorCheck module of Imatest Studio 3.7 from www.imatest.com. The program compares the measured color values from a color-checker image to the standard color numbers of the Color Checker then plots the difference on a CIE chromicity diagram, where the squares are the standard color position, the circles are the measured color position, and length of line in between is the color-error. In general, error in-and-out from the center is saturation error, while error around the center is hue error. In a 3D plot luminance error is also shown but harder to visualize without a way to rotate the plot around. Imatest provides this visualization in its Multicharts module.
I used the ProPhotoRGB colorspace when saving the TIF out of ACR because the standard ProPhotoRGB color-checker numbers in Imatest are for D50 lighting whereas the AdobeRGB standard numbers are for D65 lighting. As the image-filenames suggest, I used a linear toning curve and a black-point of 0 when saving out of ACR, but left the brightness at 50 and the contrast at 25. I tried zeroing out the brightness and contrast or using the Medium Contrast toning curve but things were way off. Using a blackpoint of 0 instead of the default of 5 also made things slightly better. There are scripts that can compute the optimal toning values for the gray patches but I was only comparing profiles, not trying to optimize them completely.
