Pentax K10D: Camera profiles, "ACR 4.x" vs "Pentax 1.00". Which one is broken?

Hardware: Pentax K10D, use DNG raw format.
Software: Pgotoshop CS3, ACR 4.5, Windows.
ACR allows me to select one of four profiles:
(1) ACR 4.4
(2) ACR 3.7
(3) Embedded
(4) Pentax 1.00
And results of this selection is dramatic. And strange, too.
I have one shot with XRtie ColorChecker.
I select "ACR 4.4" (default) profile and set white balance by second gray patch in raw (18% gray) with White Balance Tool. Color temperature is 8000 and tint is -20. Ok.
I select "ACR 3.7" profile, repeat WBT, and get same results. Ok.
I select "Pentax 1.00" profile, and get.... Temperature 11500K and Tint +75!
I know, that profiles change color rendering. It is ok.
But why these two (ACR 4.4 and 3.7 is almost the same) profiles change color rendering SO DIFFERENTLY? Color temperature is universal number, daylight is about 5500K, good flash is always 5500K, D65 light source is 6500K (6504K), etc.
I thought, that good profile should give good neutrals, and in case of controlled light, calculated (by gray patch) color temperature should correspond to light source.
I understand, that different profiles could render skin tones, cyans, shadows and highlights slightly differently, and there are many discussions, which profile is better. But 3500K difference is not "slight difference" and is not question like "I like skin tones with this profile more that ones with another"! Am I right?
It seems, that one of profiles is broken. Which one? Why difference is so huge?

Essentially embedded was broken, not in the colors, but in the white balance mappings. There was an issue with the white balance values in the profiles originally embedded in the Pentax DNG files. As long as you do a click-WB __AFTER__ choosing your profile, the actual colors should be fine (but won't and aren't expected to match the ACR 4.4/3.7 rendering exactly).

Loading Camera Profiles for ACR

Hello All, I downloaded the camera profiles from Labs.Adobe.com, ran the setup which looks like it put the data in the "Settings" folder under the "Camera RAW" folder.
When I go to Camera RAW and select Camera Profiles then Load, a dialog box opens looking for camera raw settings.xmp in the settings folder, however, the folder is empty.
Where did I go wrong?
Thanks for any help,
Jan

First off, you need to post what version of Photoshop and Camera Raw you are using. Second, while you can indeed download the old "beta" DNG profiles, you may as well forget those and download the final shipping version which is part of the package for installing DNG Converter 5.3. Go to the DNG Product Page and download the 5.3 version-the DNG Profiles (the final release versions) are part of that install See: DNG Product Page
Then I think you are confused on how to use the profiles...when properly installed and using Camera Raw 4.6 in CS3 or at least 5.2 in CS4, the DNG Profiles will show up under the Camera Calibration panel...only when loading a raw file–there are no profiles for JPEGS. Also, the number of profiles and their names will vary by camera. You can _NOT_ load profiles into Camera Raw from within Camera Raw...if you are using the flyout menu at the side, that's the wrong way of using them.
You really need to do some reading...see the docs on Labs at the DNG PROFILES page scroll down and read the Getting Started section. If you want further help, post your system, ACR version and camera...

Camera profiles and Untwisted Adobe Camera Profiles

If memory serves me correctly, mention was made a while ago about the Recovery slider within LR - basically how bad it was. Um? At this time, again if memory serves me correctly, someone mentioned something about 'Untwisted Profiles'.
Anyway, following a link from another forum I ended up here http://thomaslesterphotography.com/photography/untwisted-adobe-camera-profiles/ and thought I might just give it a go. However, I am unable to locate the folder in which Lightroom stores it's camera profiles. If I follow the route (in Windows), Documents and Settings, User, Application Data, Adobe, Camera Raw, Camera Profiles I only find a index.dat file which obviously isn't the correct place.
Could some kind soul kindly point me in the direction of where these Untwisted Profiles should be placed (Windows)? Curiosity is getting the better of me and I really want to (a) see what all the fuss is about (b) is it justified and (c) do these Untwisted Profiles really make a difference. Nothing ventured nothing gained eh`? lol

ElliR,
What a great move of Thomas Lester to publish all these profiles
About the installation:
Thomas refers to “C:\Documents and Settings\All Users\Application Data\Adobe\CameraRaw\CameraProfiles\Camera”, which is where LR (and ACR) stores its delivered profiles. You can put the untwisted profiles there, under your camera folder.
But, if you want to keep them separate (which I prefer), you can also put them into the user specific folder (this is also where LR puts its presets). In this case, create a folder Camera in “C:\Documents and Settings\your-user\Application Data\Adobe\CameraRaw\CameraProfiles” (this is where you found the file index.dat) and copy the entire folder for your camera from the ZIP file into that Camera folder.
In both cases, you'll be able to see the new profiles in the Develop Module.

P.S: These folder locations refer to WinXP. To find out your local presets folder for your OS, use Preferences / Presets / Show Lightroom Presets Folder.

Odd Camera Profile / Undo Bug in 2.3 RC

I downloaded the LR 2.3RC tonight and although it seems to be running faster, I've noticed a strange bug that I've never noticed before (or that wasn't there before.
When using develop presets that change the camera profile (for example Matt Kloskowski's 300 Look) the preset will be applied and then after that the camera profile is changed as a separate step in the History palette (however I have only clicked on the preset and haven't changed the camera profile).
When clicking undo the overlay that tells me what step I am undoing says that it is "Undo Camera Profile: ACR 4.4" - however this step either (1) gets undone and immediately re-applied, or (2) never gets undone. This problem makes it impossible (without using the History palette) to revert to the step before - and it kind of makes it difficult to apply several presets to see which works best as I have to scroll to the History palette to undo it and apply another.
This bug only exhibits itself when using presets which change the camera profile.
Anyone else seeing this?
Any work arounds (other than reverting to 2.2)?
Thanks,
Chris

Hey Chris,
Yes I can reproduce this same exact problem on my Macbook Pro (Feb. 2008) with 4GB RAM and 10.5.6 with Lightroom 2.3RC
I tried this on Lightroom 2.2 and I can say that this problem does not happen. This is a Lightroom 2.3RC bug.
Is there a place where we are suppose to report RC bugs or is this post enough? Thoughts Adobe?

How to set default camera profile?

Hi,
I'm using LR 2.2, and have the camera profiles (love 'em :)
I'd like to arrange that one of these become the default for new imports. How should I do that?
TIA
Simon

There are two ways. One is to take an image taken with the camera you are using. Then you hit reset and the only thing you do is to change the profile to the setting you'd like. Then you hold alt/option and the reset button will change into "set default.." just hit that and now all new imports from that camera will use the profile as default. Secondly, what you can do is generate presets that apply only the profile and simply apply them during import.

New camera profile not "appearing" in ACR, but does in Lightroom

I recently created a camera profile for a Nikon D200, using an X-Rite Colorchecker chart photo and the Chart feature in the DNG Editor. I exported the camera profile. When I go to the Calibration tab in ACR 5.5, the new profile does not appear in the drop down list with the other camera profiles. However, when I go to the Develop module in Lightroom 2.5, the new profile does appear in the drop down list there.
I am running Windows 7. Snooping around my root drive I find that if I look within the Users\User Name\AppData\Roaming\Adobe\CameraRaw\CameraProfiles directory (referenced in the Fraser and Schewe CS4 Camera Raw book as the Vista location for the profiles) I can find no camera profiles and when I place the new profile there it still does not appear in ACR. When I look in ProgramData\Adobe\CameraRaw\CameraProfiles\Camera\Nikon D200 directory I can see the regular set of camera profiles for the camera, as well as the one I created, but as I previously stated, the newly created profile does not appear in the ACR list.
A side note - I did some experimentation with camera profile names. I added "XX" to the end of the Nikon Vivid profile name (not the extension), and then that profile no longer appears in the ACR list of profiles. I removed the extra letters and then the profile reappears in the ACR list of profiles. Seemed odd behavior to me. I also noticed that the profile I created with DNG Editor is noticeably smaller than the others provided by Adobe (28K compared to 110k).
Hope someone has a suggestion for me.

Your reminder about both Photoshop (main) and Bridge needing to be shut down for changes to take effect reminded me that I had Bridge set to "auto-start at log-in". So I checked and it was still running (shown with the other hidden icons). When I "shut it down" from the UI I had thought it was fully terminated. So I completely shut Bridge down, restarted, and the new profile now appears.
Thanks for the reminder/pointer in the right direction.

ACR 5.7 can see camera profiles in Bridge CS4 but not in Lightroom 2.7

When utilizing ACR5.7 through Bridge CS4 - the cameral profiles are easily applied for my .NEF files (Nikon D300) but when I am in Lightroom 2.7 the camera profiles are not available unless I convert the nef to DNG. I have tried to search the web and these forums but I am unable to locate the answer to my problem:
Why can't I see the camera profiles in Lightroom for my nef files when I can see them through Bridge.. (both running ACR 5.7)
Windows XP xp3
Lightroom 2.7
Bridge CS4
ACR 5.7
Nikon D300 profiles
Thanks for the help.

For those who might be reading this and having "odd" problems .. my solution was to delete my preferences file.

This solved several odd issues I was seeing in my lightroom including the camera profiles..

ACR 5 - Support for Custom Camera Profiles

ACR 4 allows users to select from a list of four device-independent colour spaces (Adobe RGB 1998, ColorMatch RGB, ProPhoto RGB and sRGB). Unlike other RAW processors, it does not allow selection of a custom camera profile. This capability is very useful when colour accuracy is of considerable importance (e.g. reproduction of art works). Does ACR 5 allow for selection of custom profiles?

When this question had been asked in the past the answer has always been, "No, because these choices are all that you need." This may seem to be a rather close minded answer. But in reality the Prophoto color space encompasses everything else that is available. So the solution has been to do all of your work in ACR in Prophoto and send the image on to Photoshop in that color space. Then convert to the desired color space in Photoshop.

Recovery Slider: Color Changes with Camera Profiles, not so much with ACR 4.4 Profile?

I'm sure there's a reason for this, and not necessarily a defect, but I have to ask:
The recovery slider: if I use the Recovery Slider on an image set to the ACR 4.4 camera calibration profile, this helps control my highlights without affecting the overall color/tint of the image. However, if an image is set to the Adobe Standard camera calibration profile (or any of the other camera profiles) and I use the Recovery Slider on that image, the affect on the image seems to be different: the highlights are also controlled, but not without a perceived effect on the color tint of the image. The color balance almost seems to slightly change. Particularly noticeable on skin tones. I'm working with 5D files, using Lightroom 2.3 on a Mac.
What's the reason for this? Anyone experience similar?
Thanks

This is a known "problem". It is caused by "hue twists" that are present in the camera-matching profiles and the new Adobe profiles. Several threads on this in the ACR forum:

Cannot see ACR 5.3 update in the Camera Profiles on CS4

I'm using CS4 on Windows Vista 64. I have tried the manual installation process multiple times before and after re installing CS4. I've tried the AUM with no results good or bad. I know there are two Camera Raw.8bi files that have to be installed in Vista 64 and I've been very careful to get both of the correct files to the correct destinations - I've gotten a lot of practice at this. There have been no error messages. One thing Bridge is doing now is that when I open an image, it opens it in Elements 7, which I upgraded from. When I close PSE7 and reopen the RAW file, it then opens in CS4. My big concern however is not seeing ACR 5.3 in my Camera Profiles. Any thoughts for a non-techie?

Robert, I am having a similar problem with Elements 6, in my case I have installed the 8BI file on my desktop, and I can see all the options Jim describes in camera profile My camera is Nikon, so those are the options I should get. But on my new laptop, all I get in camera profiles is ACR 4.4. I originally downloaded the most recent camera raw update to the laptop, but when that didn't work, I copied the 8BI file from the desktop to the laptop with a memory stick, and I still get the same results - no options. Camera raw on the laptop does recognize my camera, and lists it at the bottom of the preview screen, but it does not populate the options in camera profile.
I distrust the answer you got from FAQs, because my camera did not exist at the time ACR 4.4 was released, and it really does not explain why I can't get the same camera profile selections on the laptop as I do the desktop. Both are Dell, Vista 32. Both are PE 6. Both are the same camera, and now, the same 8BI file. And both show ACR 4.4, The 4.4 doesn't bother me, but I want the camera options on my laptop.

Camera Profile missing in ACR 6.7 (PS CS5)

I have looked all over the place for a solution to this problem and so far can not find one.
I am running Windows 7 64bit, PS CS5.
I just noticed that my Nikon D90 camera profile is missing under the Camera Callibration area in Camera Raw (it had been there before). The only thing that shows up is ACR 4.6:
I have tried reinstalling the ACR 6.7 plug in...didn't work.
I really don't want to try to uninstall and reinstall Photoshop.
Oh, I have also looked on my computer in my C drive and found the list of camer profiles...the D90 is not listed (in fact, there are only 8 Nikon cameras listed in my Adobe Standard folder).
One more thing...I had CS4 installed originally. I have since uninstalled it. I'm not sure if the issue I am having has to do with that or a recent update.
Adobe should really have a seperate file that you can unstall just for camera profiles.
Like I said I have searched all over and have not found anything...I am really hoping there's someone on here that can tell me how to get my camera profile in there.

I recently installed Windows 8.
1. Can I get a ACR profiles for my Canon 1Ds Mk lll and my Sony RX 100?
2. Can I install the DNG Converter on Windows 8? This OS isn't listed as here as one of those suitable. > http://www.adobe.com/support/downloads/detail.jsp?ftpID=5389
3. Noel, where are the equivalent locations on a Windows 8 machine? ProgramData doesn't exist, as far as I can see.
Thanks.
D.
Edited:
Ok. I found another Adobe download that said Windows 8 is compatible, so I installed the DNG Converter.
However, no cameras are listed under Camera Profile in ACR.
This is the case whether I load a Canon RAW file or a DNG conversion of a Canon file.
Any idea how I can get the profiles to load?
Thanks.

"Camera Profile" in Camera Calibration ACR tab - Q

I upgraded from PSE5 whcih used ACR 4.7 - and now using PSE8 w ACR 6.1
In the Camera Calibration tab in the Camera Profile drop down - I see "ACR 4.7" still listed.
Can someone tell me how to make use of this tab and how I can delete the ACR 4.7 and use 6.1 - if there is a benefit to doing so?
Thank-you!

I think the issue could be that I have both PSE 5 & 8 installed at the moment. I'm using the 30 Day Trial - and I'll uninstall PSE 5 once I get my actual disc & serial # in the mail. I did not want to uninstall v5 until I had the v8 serial # and was convinced that v8 worked well. During the v8 installation - it recognised v5 but said I can keep it. My concern is uninstalling both and reinstalling v8 and having catalog & stack issues.
I installed the camera profiles as Adobe directs "before" pasting the new ACR 6.1 file in the folder.
Nevertheless, I installed the cameraprofiles.exe again today - previous to posting this thread.
I guess a main question is - what would I be missing out on by not having ACR 6.1 in the profile? (vs 4.6)

Camera Profiles and Lens Profiles are missing in ACR 8.2.

Yesterday I tried to install a new update for CS CC, but it failed. Then I uninstalled the app completely, and installed it again.
When I opened ACR 8.2 I found out that there were no Camera profiles and LensProfiles (as it used to be before). Instead of usual Camera Profile was Matrix. There were no Lens Profiles in Photoshop Lens Corrections either.
The folder C/.../App Data/Roaming/Adobe/CameraRaw/LensProfilesDefault was also empty.
I reinstalled the application a couple times with the same result.
How can I fix the problem?
Regards, Yulia

Well, C:\ProgramData\Adobe\CameraRaw\CameraProfiles\Adobe Standard is also completely empty.

Cs3, camera raw 4.0, camera profile is locked at acr 3.3

Hello
i am using pscs3, and wanted to use a colorchecker passport to fine tune my color balance. i *thought* that after running the xrite software, that their profile of my D200 would appear in a dropdown list under "camera profile" in the camera calibration tab of ACR 4,0 --- but the camera profile is locked at ACR 3.3, and there is no dropdown. suggestions are very welcome.
thankws

Most of the problems with ACR are one of 2 things. Either you have more than one copy in the folder, or you have it in the wrong folder.
In PS click on help/about plug-in/camera raw. See what you have.
Plug in should be in program files/COMMON FILES/adobe/plugins/CS5/file formats

Should i see same camera profiles in LR as i see in ACR?

I use macintosh and OS 10.6.6
I have found that i can see only the original camera profiles in ACR but can see eric chans's profiles in LR, in addition to the original camera profiles.
I have searched ACR, PS, and LR fora, as well as adobe websites and cannot finder an answer clear to me.
I have moved files between " /user/library/applicationsupport/adobe/camera raw/cameraprofiles",
and the "/library/applicationsupport/adobe/cameraraw/cameraprofiles" .
I do not see the same profiles, with lightroom showing eric chan's profiles, but these are not available in ACR.
I expect some simple answer and am prepared for disparagement, but i need some smarter person's advice and help.
thanks to any and all,
vince

thanks so much charlie.
that does not seem to work here. but perhaps i need to try again and delete some preferences, etc.
very grateful for your reply, which i think is probably the correct answer.
