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.

Do ColorChecker Passport camera profiles move with the image?

Hi. I work in an office where 3 of us process DNGs into psd's. When using a colorchecker passport-made camera profile on User 1's mac, we then open the image on User 2's mac. If we look at the DNG in Camera RAW on User 2's mac, the camera profile User 1 chose is no longer listed in the camera calibration tab. Is this a problem? Does the info still hold in the DNG for User 2? Is the only solution to for User 2 to copy the profiles from User 1? Thanks, in advance, for your help!
-Bret

Look in the Camera RAW preferences, and see if you have Save to XMP or Save to Camera RAW Database set for where to store settings, and also whether you have Update JPG Preview enabled or not for the DNGs in question on User1’s computer. I don’t know if having both of these enabled would help store the profile for use on User2’s computer or not.

Color profile problem/question.

These two exports of the same file were taken on my spouse's D300s, and are good examples of a profile problem I cannot seem to solve. This is the identical problem I also experience on the Nikon D700 and D3. The following was exported with the "Camera Standard" profile, and notice the yellow sun reflection on the door panels:
The following was exported with a xrite generated lightroom profile. Notice the better overall contrast, but also the horrendous unnatural yellow on the same door:
This difference causes all sorts of distortion in natural animal hair that contains any red-orange. I use these doors because they are such a stark example. Any attempts to correct with the WB will usually result in too much blue elsewhere. Also I have created many test profiles under many light conditions (both manually and from LR), and they all cause this problem in all three cameras. This is not a matter of one bad cameral, or one erroneously created profile.
I have two questions: Does this example show up well enough to see what I am talking about? If so, can anyone speculate as to the problem or solution? Even guesses would be appreciated since I am out of my own, and not expert in this sort of thing. Thanks!

George, thank you for this information. I have a couple of things for you to try and another question. The ColorChecker Passport color patches are small, so I would suggest trying to reshoot a calibration image with the ColorChecker Passport in the center and filling at least 1/3 of the picture width. In the image you provided the ColorChecker Passport is about 1/8 the image width and far left of center. I know, I know, it should not matter, but give it a try. This is what I'm doing to create camera profiles for all three of my camera bodies (Canon 300D, 600D, 5D MKII), and I have not had a single problem with "color matching" using this procedure AND what I will describe next.
Concerning white balance procedure you say:
Using the grey card of the same product placed just outside the subject crop.
I assume you are referring to the large 60% reflectance white balance card on one side of the ColorChecker Passport, but you do not mention how you set white balance. I suggest using the LR white balance eyedropper tool with the smaller 80% reflectance gray scale patch on the ColorChecker Classic target side. This is the 2nd patch from the left bottom in your picture right next to the brightest 90% white patch. Two reasons for doing this! A higher reflectance patch reduces the influence of camera noise in the image with the LR 5 x 5 pixels eyedropper tool. Here's a LR forum post with a heated discussion on these issues (or lack thereof): http://forums.adobe.com/thread/854734?tstart=60 The second purely empirical reason is the "Classic" target side provides me with more accurate white balance than using the larger 60% card. Perhaps this is a defect with my ColorChecker Passport target, but I don't know.
When setting white balance with the LR eyedropper tool I suggest taking at least five (5) samples of the 80% patch. I use the center, TL, TR, BR and BL corner areas of the patch. Do not use any reading that has a large variation from the others. Please remember that the eyedropper tool is sampling a very small 5 x 5 (25 pixels) area, and image noise or a target paint defect can give you a bogus reading. Write down the temp and tint for each of the five (5) readings, add them, and divide by five to get the "average" white balance temp and tint. Enter the temp and tint values manually into the white balance tool. I create a user preset for each profile which contains only the ColorChecker created camera profile and manually adjusted white balance settings.
I would also suggest you check the readings of all six (6) grayscale patches for neutrality (R=G=B) using your new camera profile and white balance settings. I have found in some cases using the 65% reflectance patch (3rd patch in) provides the most neutral “overall” white balance setting for the six (6) patches. This is despite the fact it contains more camera noise than the 80% patch next to it. Again, this observation is purely empirical – I am not writing a scientific thesis! It works for me and hopefully it will get you closer to what you want.
One thing I am going to do tomorrow is borrow a friends color checker to rule out the possibility mine is defective. It doesn't look defective, but the problem is so consistent.
This is a very good idea! Having worked in a manufacturing environment for over 45 years, trust me when I tell you defective product from even the largest company ends up in the consumer’s hands. Please let us know what you find.

Lightroom 5.5 and Colorchecker Passport profiles

Hello,
Having calibrated my Sekonic L-758 meter, I have subsequently been trying to create a camera color profile in Lightroom 5.5, following instructions available online from webinars such as Joe Brady's. Having taken my 3 RAW photos of the Passport, I converted the middle one to DNG format and created a profile using "Export with Preset | Colorchecker Passport in Lightroom. According to the software, the profile was created, however it never shows as it should in the Camera Calibration section of the Develop module of Lightroom. Can you tell me in which folder the .dcp file representing the profile should be located for Lightroom to take it into account? My PC runs Windows 7, fully updated. Many thanks in advance.
Best regards,
Dominique

You do have to restart LR to have it rescan what is in the Users CameraProfiles folder.
In your initial description of how you created the file, you said you converted to DNG and then Exported with the CCPP preset. In my experience you do not have to convert to DNG, first, just select the raw file and Export with Preset. The process that requires converting to DNG, first, is if you use the Adobe DNG Profile Editor to make your color profile.
If you want you could post the Fuji raw file, not DNG, here, someone else to try it and see if the same thing happens. Use dropbox.com or similar and post the download link.

Colorchecker passport and the DNG profile editor

I finally got around to getting a Colorchecker passport to use with the DNG profile editor.
I was secretly hoping I could save time by shooting the chart on location and make an instant profile out of that - then the colors would be at least "close ballpark" so I would just have to apply white balance and then move on to more specific adjustments. But of course it wasn't that easy, it still takes a fair bit of color tweaking to get right in most circumstances.
So I'm wondering if my energy would be better spent trying to perfect one good dual illuminant general profile. For this I would use 3000 K tungsten at one end and 5500 K studio flash at the other. Or would it be better to use overcast daylight? In either case it's obviously important to ensure the chart is absolutely evenly lit.
And then I should probably have a separate profile for fluorescent tubes.
I'm curious what other people's experiences with the colorchecker/DNG profile editor are? How are you using it?

The color profile changes with the lighting, so a profile that was computed for daylight won’t be right for tungsten or fluorescent. Keep in mind that a custom camera profile is the set of corrections on top of an existing Adobe profile that the DNG has assigned to it, perhaps Adobe Standard, and all Adobe profiles are dual-illuminant profiles, so it makes sense you’d want to also create a dual-illuminant profile for general purpose use that has the same two lighting scenarios as Adobe used: 2850K and 6500K. The 6500K is the tricky one because full sun is warmer, closer to 5000K, and you need the right amount of haze to create 6500K sunlight, unless you are using standard D65 bulbs, indoors, which is likely what Adobe does.
I use a dual-illuminant profile for general purpose use, but since the WB-Tint values of both the tungsten and daylight ends are close to zero, lighting that has a tint not close to zero needs a separate profile. The common example is the greenish light from fluorescents, and I have several single-illuminant profiles for various artificial lighting scenarios with WB-Tint values that are relatively non-zero. I also have ones for very red sunsets and very blue twilight. If I had studio lighting I’d make a profile for that. Sometimes I make a custom profile for a church or other venue that has significant non-neutral walls or ceilings, or where sunlight through the stained-glass windows shining on the walls are giving a significant color-cast including a non-zero tint value to the lighting. If you know you’ll be doing some shots near a large amount of tall, green vegetation then a custom color profile can correct for the green tinge to the ambient lighting coming down from above mixing in with the sunlight.
Adding to the suggestion about wearing neutral clothing, I’d argue for dark neutral clothing because something lighter clothing will reflect environmental colors (sunlit vegetation or brick walls, etc, outdoors) and not be neutral.
Besides non-neutral clothing, try to avoid areas that have green grass or tree leaves or brick buildings that also color the light and reflect off the colorchecker. For the sunlit shots, I put my colorchecker face up on the sidewalk or parking lot, to avoid coloration from the grass and far away from trees or buildings especially in the direction I’m pointing the camera, so the only lighting is direct sun and ambient blue-sky, possibly diffused by hazy clouds. I point the camera down at the colorchecker, at a 45-degree angle and at a compass direction and not directly toward the sun, nor directly away from the sun. I try to shoot the target that is face up on the ground perhaps at a 90-degree angle from the sun to minimize any residual glare from the colorchecker’s slightly non-matte surface. Obviously directly away from the sun, the color-checker will have my shadow on it or I will be blocking the light from the sky near the sun.
I use the same sort of process for the tungsten end, choosing a room with neutral walls and put the target relatively flat on the floor facing up, perhaps tipped up somewhat toward the light, but not so much as to have any glare from the lighting, either, in other words, not with the lighting directly behind the camera, but somewhat over to the side.

X-rite colorchecker passport profile created but does not appear in the Camera Calibration tab!

I have installed x-rite colorchecker passport and lightroom 5.0. I followed the tutorial in setting up my camera profile and lightroom reported created successfully. However after restarting Lightroom, I could not find my created profile other than the Adobe Standard in the Camera Calibration tab.
Please help !

X-Rite has a free DNG Profile Manager that can be downlaoded after registering your ColorChecker Passport here:
http://www.xritephoto.com/ph_registration.aspx
You will be offered a link to download the free app. See if the profile you created is visible with the app.
Here's where the user camera profiles should be located with LR5:
Windows—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ CameraRaw \ CameraProfiles \
Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / CameraProfiles /
Profiles are camera model specific so a Canon 600D camera profile will only be visible when a 600D raw image file is selected. You need to create profiles for each camera model separately.

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?

Aperture and colorchecker passport from X-rite

the colorchecker passport is a tool to make color corrections by camera profiles.
(http://www.xritephoto.com/phproductoverview.aspx?id=1257&tab=videos)
nice program to get my color workflow better accept i use aperture and.. that just doesn't work some how. even adobe's lightroom got a plugin for this beautiful thing but aperture doesn't give any options to use a camera profile. Unbelievable because this is so important if you're doing commercial photography.
I hope some one can help me with my issue because i dont want to leave aperture and work with lightroom...

Just one other comment about this kind of workflow in general.
While absolutely accurate color rendition and absolutely neutral WB can have their uses they are few and far between. Virtually every single commercial image ever viewed has nowhere near "accurate" color or WB. In fact the whole demo video itself is shot so freaking warm it's actually funny. Not only is the video shot warm but just about everything done, from the time of day it was shot to the use of gold reflectors is done to achieve warmth of color while the guy talks on and on and on about how the product helps you achieve accurate color - that's hilarious. Why would you ever go through the trouble to get the light and color so warm just to neutralize it out. His video shooter/processor/editor didn't think it was such a good idea to neutralize it - in fact the video guys actually cranked it up. Really funny stuff. Hmmm what happens when you shoot when the sun is really really warm and you use a gold reflector and a neutral WB target to adjust your WB? Answer = gold/warmth goes away - freaking brilliant. Hmmm maybe he should talk about how the video guys just set the WB to 5500 or even higher temp and captured all the wrong but warm color.

X-Rite ColorChecker Passport specifically targeted at DNG workflow

Hi folks, I reviewed the X-Rite ColorChecker Passport system
(review of ColorChecker Passport here: http://www.it-enquirer.com/main/ite/more/colorchecker_passport/)
What I find mildly annoying in this X-Rite solution is that it only creates DNG profiles. While that is great when you're working with Lightroom and Photoshop only, it's ineffective if you also use other applications like Capture One Pro.
You can of course use the ColorChecker hardware to create an ICC profile, using ProfileMaker, but I was wondering if one can't convert a DNG profile to ICC. I tried to open the DNG profiles on my Mac OS X machine, but they aren't package bundles, so there is no measurement data to be extracted for example...

With full disclosure, I don't own the color checker passport but I've played around with it and I agree that it is pretty cool. I haven't used it in conjunction with an Aperture workflow, but Aperture is my main tool in processing/maintaining my image files (along with photoshop). The software that allows the colorchecker to work with photoshop/acr/lightroom is pretty usefull, but unfortunately, as you've found, the colorchecker doesn't work with Aperture in the same way.
My suggestion would be that while you can't create profiles in the same fashion in Aperture using the colorchecker as the colorchecker does with lightroom, you can still make a preset based upon the passport itself.
I'm pretty sure that you could make global adjustments/enhancements to an image of the passport, make a preset, and apply it to other images in similar lighting. Not as slick as the interfacing of the colorchecker and acr/lightroom but I'm pretty sure it would work nicely.
I'd be curious to hear with others have to say.
Best,
CD

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?

Colorchecker Passport not working in Lightroom 5.6

I have been using the colorchecker passport while photographing my art for about a year now and have not had problems with it until recently. Now Lightroom 5.6 will not show my profiles in the camera calibration area nor will it create a new profile. When I try to create a new one it says it cannot be generated. When I run a report I get this message:

I tried creating a new profile with the x-rite Camera Calibration Software and got the same report. I don't know if the problems in with the OS, Lightroom, or x-rite. Here is what I am using:
Windows 8.1
Lightroom 5.6
ColorChecker Passport Adobe Lightroom Plug-in (3/15/2011)
Color Checker Camera Calibration 1.0.2 (6/22/2010)
I also tried removing all the x-rite software (both the plug-in and stand along software) and reinstall it, but that did not fix anything.
Any ideas?

If you can figure out how to upload your newest DNG to Dropbox I may be able to help you analyze what is wrong, otherwise, I can only guess from what you've said. A partial substitute for uploading the DNG would be to post a screenshot of what it looks like as you did, originally so at least a judgment can be made about whether it is shot correctly or not.
The DNG you linked from Dropbox gives me a reasonable error message, yet it seemed to give you something else. This is what I don't understand, unless you're using the older CCPP app, rather than the slightly newer one, so first, make sure you've downloaded the 2010 version of the software and the 2011 version of the plug-in that interfaces with the software, in case what you've installed from the disk is the original version.
One of these links appears to be just the plug-in and one has both the software and the plug-in as separate items. I assume the plug-in is the same for both but I'm including both links just in case one is newer. Since the one that is just the plug-in mentions Windows 8, I assume it is the most up-to-date.

Secondly, if you still have them try profiling the original NEFs instead of the DNGs.
Thirdly, if you must make DNGs, it can matter what the Compatibility Level is and try an older one, since the CCPP software hasn't been updated in several years. This doesn't seem to matter for some cameras but it does for others.

Creating color profiles Leica D-Lux 4

What version of Bridge/Photoshop are you running?
Is it X-Rite's Passport software or Adobe's DNG Profile Editor software that is giving the error? I ask this because you talk about using Passoprt to create profiles, but then describe the error has coming from the DNG Profile Editro which is Adobe's software.
What process are you following, starting with the RWL file, that gives the error about not having a valid DNG file?
I know X-rite released an update to their software a few months ago.
You might post one of your RWL files via YouSendIt.com to let others try and duplicate your scenario.

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.

X-Rite ColorChecker Passport workflow?

Anyone using an X-Rite ColorChecker Passport for adjusting color, or creating profiles? I'd like to do this for important shots, or shooting sessions with consistent light.
It is very useful to shoot a test shot of the ColorChecker Passport and use it with the ColorChecker software, ACR 6, and Photoshop CS5 to adjust color in a particular lighting situation. IMO, it improves color from shots with a Nikon D700. It also helps keep color looking consistent when shooting with two different cameras.
I'm trying to figure out if there is a way to use ColorChecker test shots in Aperture. Anyone have suggestions?

With full disclosure, I don't own the color checker passport but I've played around with it and I agree that it is pretty cool. I haven't used it in conjunction with an Aperture workflow, but Aperture is my main tool in processing/maintaining my image files (along with photoshop). The software that allows the colorchecker to work with photoshop/acr/lightroom is pretty usefull, but unfortunately, as you've found, the colorchecker doesn't work with Aperture in the same way.
My suggestion would be that while you can't create profiles in the same fashion in Aperture using the colorchecker as the colorchecker does with lightroom, you can still make a preset based upon the passport itself.
I'm pretty sure that you could make global adjustments/enhancements to an image of the passport, make a preset, and apply it to other images in similar lighting. Not as slick as the interfacing of the colorchecker and acr/lightroom but I'm pretty sure it would work nicely.
I'd be curious to hear with others have to say.
Best,
CD
