Camera calibration accuracy

Does anyone know which is the expected accuracy for a camera calibration?
I have to calibrate the camera, and depending on the calibration accuracy I would use a points grid that I have or try to get a new one with greater points density.

Camera Calibration

Using Bridge cs4 and note VERY different color rendering depending on choosing "Adobe Standard" vs "Camera Standard" (cr2 files Canon 5d) in the Camera Calibration choices.
I have used gray card for white balance, and studio lighting - this is not the issue.
How do I know what is the 'correct' color ?
How do I prevent this problem ?
Attached (I hope) is a link ot a flickr photo where I compared the two renderings of same image:

Amen. And the end user monitors of course, most of which are too cheap to be able to be profiled (e.g., because of shifts due to viewing angle).
I managed to get Microsoft to admit once (privately) that they've programmed the color-management in the Internet Explorer browser in a half-baked fashion - to always assume the monitor is sRGB regardless of profile. It's done on purpose but they wouldn't say why - and it's not going to change any time soon. I figure there could be one or a number of reasons:
1. More folks might complain about problems, raising their support cost, if IE were to embrace monitor profiles. It's an element outside their control, though one wonders why they couldn't just create a truly robust color-management module that would either work or fall back to sRGB if it failed. Perhaps Microsoft doesn't have that kind of talent.
2. Microsoft's priorities and thus their direction have gone a bit wacky, with their recent all-eggs-in-one-basket pursuit of the tablet market. Have you noticed that color accuracy seems to be a non-priority for portable electronics? As long as red things look sort of reddish, good enough?
3. Most non-technical / non-professioal users don't really care about color-management, and in fact may run away from it screaming. Laypeople tend to like the "more vibrant" color they see when an sRGB image is displayed on a wide-gamut monitor. Where's the incentive to desaturate those colors? Back to item 1 above.

Lightroom: Why does auto white balance no longer work after changing the camera calibration profile?

I'm using NEF raw files from Nikon.
Lets say for example I import a NEF file into Lightroom (v4) and click on 'auto' for white balance. The white balance in the image is adjusted correctly (somewhat). However, if I then change the camera profile (in the camera calibration section) from 'adobe standard' to 'camera standard' then the white balance in the image becomes very wrong. I then have to set the white balance back to 'as shot' and correct it manually instead.
Why would 'auto white balance' no longer work just because I change the profile from 'adobe standard' to 'camera standard'?
Any ideas?

Works as expected here...
Which Lr version and what OS??

How do you get the camera information to show up in Camera Calibration in Lightroom 5

I have a Nikon D7000, I am trying to get the information to show up in the profiles of Camera Calibration. It shows up in my metadata in the library module but not in the Camera Calibration. I am looking at a RAW photo too, so it should be there. Adobe says that the camera is supported in Camera Raw 6.3 and I am using Camera Raw 8.2 in Lightroom 5.2. Any help is appreciated.

Moving discussion to Lightroom forum.

Camera Calibration Profile in Adobe Camera Raw 5.3

I'm trying to figure out the Camera Calibration tab in Adobe Camera Raw 5.3. It seems that every picture I open selects a different Camera Profile in the drop down menu. How do I know which one is appropriate for my camera (Nikon D40X)? Or, do you just select whichever one looks the best to you on the drop down menu for that picture? Or, does it matter that much at all since they never had this tab in there before?

I'm not sure I understand...when I open an image in Adobe Camera Raw 5.3, does it open with a different "default" for each picture? Or should I be using a specific profile from the pulldown menu, e.g., ACR. 4.4 or "Standard Adobe" or should I try them all and see which one I like?
Thanks.

How to Save Camera Calibration and Lens Correction in Camera raw 6.1

I downloaded and installed the Camera Raw 6.1 release candidate. I open an image and set the camera calibration and the lens correction to auto for Nikon. I save these settings as new Camera raw defaults, but when I open other images, the changes were not made. How can I save these items as defaults?
Swila

Swila, were your "other images" previously edited in Camera Raw? I.e., do they already have saved image settings? The defaults that you save via the flyout menu will only apply to new images, or if you reset an existing image to the defaults. (e.g., choose "Camera Raw Defaults" from the flyout menu).

What does "Camera Profile" mean in the Camera Calibration tab in PSE 12?

I recently made the switch to edit exclusively in Photoshop Elements 12. I need help understanding what I need to select for the "Camera Profile" drop down in the Camera Calibration tab. I shoot with a Canon Mark II. Will the camera profile selection affect my prints at all? First, what does the camera profile mean? I go back and forth between Adobe Standard and Camera Standard. Sometimes I get truer color with Camera Standard than the Adobe Standard for my outside photos. I'm so confused as to which one I should be editing with. I just want to be sure this is not going to affect my prints because I just recently ordered a print from Millers and it was saturated, shadowing and skin had orange tone. I have never had a problem with my calibration and have always ordered from Millers with no problem. This is the first print I ordered after editing exclusively with PSE 12 so I'm wondering if I have setting wrong. Thanks so much!

Will the camera profile selection affect my prints at all?
It will affect prints to the same extent that it affects the monitor display, but no more than that. The differences that you see in color rendering when switching between profiles will be embodied in the jpg that you eventually make for sending to the print lab, but will not in itself cause the discrepancies you describe.

Problem with camera calibration profiles

I've been using Lightroom 4.2 on windows with a Canon 450D for a while and i only use raw files.
Under the "Camera Calibration" tab I could chose betwen acr4.4, Adobe Standard and a few canon presets (paysage, neutral, etc.)
In my opinion the ACR4.4 profile gives me better and more natural colors most of the time
Last week i upgraded for a Canon 650d. When I import my pictures and go the "develop", I can only chose betwen the Adobe Standard and the canon presets. There is no ACR x.x profile (replace the "x" by whatever it should be for a 650d)
It's not the end of the world but is it possible to download it ? or did they remove it completely for newer camera models.
In the "about adobe photoshop lightroom" windows, it says i have Camera Raw version 7.3. Reinstalling lightroom made no difference and all my drivers are up to date.

ACR is legacy profile. No new cameras have it. It won't disappear for older cameras though.
Adobe Standard is Adobe's, well, current standard.
If not optimal for your tastes, you can modify it using DNG Profile Editor.

Camera Raw Camera Calibration Tab and 5D Mark III

I don't think that many people do this in camera raw, but it was kind of an important step in my workflow with the Canon 7D before and is just not working the same way with the 5D Mark III now.
In the Camera Calibration Tab (Third from the right side) I always changed Camera Profile from Adobe Standard to Camera Standard or Camera Portrait. This step made the image automatically look better, contrast was better and the highlights look a lot better that way. Of course the "Camera Portrait" option makes the image a lil bit red, like the Picture Style in the camera does. But it was an easy adjustment with the Hue Slider of the Red Channel. Like I already said - really great improvement of the image on the 7D raw files, beautiful highlights, shiny, contrasty and so on... Same stuff worked with 5D Mark II perfectly, too.
Now with the 5D Mark III the "Camera Portrait" option, my favourite one, gets me pretty bad results. The Image is too strong oversaturated, too much red in the skintones and in the shadows, too! Shadow contrast gets worse and I can't control this settings the way I did before with the hue/saturation sliders of the channels. It's too extreme red or it's too yellow, but not something right between this extremes. And the highlights get some green tint, so it's no real optimization of the image overall quality at all, like with the other cameras. I don't know if the support of the 5DMIII is still not up to date... It is not only my camera, I also have asked other photographers with a 5D Mark III and they have the same issues changing the camera profile. Lightroom has exactly the same effect... It would be great, if an Adobe Employee can forward this issues, so that it gets tweaked with the further updates and 5dm3 will work the same way in camera raw like mark 2 or 7D.
Sorry for my bad english

Yes, white balance is another possible reason for mismatch
These rules apply:
- if you use white balance "as shot", then white balance in ACR will be the same as from camera or DPP (in a sense - what is white color in ACR will be white in DPP also). However, color temperature/tint shown in ACR will be probably slightly different than value recorded in exif of jpeg or raw file. It's because in that case, whitebalancing is performed using some metadata in raw file by both ACR or DPP, while temperature displayed in ACR is calculated from that metadat using color matrices in selected profile, according to a formula from one book (as documented in dng sdk), while DPP is probably using some other formula or slightly different color matrices
- the same will happen if you use WB dropper on exactly the same position in the photo by both ACR and DPP
- but, if you use the same temperature preset in ACR and DPP (for instance 5200 K), then white in ACR and DPP will probably be a bit different, because whitebalancing is performed in oposite direction now (ACR calculates RGB multipliers from that temperature and using color matrices in the profile)
I hope this was understandable, although it's a bit complicated

Camera calibration in Camera Raw 6.7 VS 7.0*

Hi again!
I noticed that in cameraw raw 7.0, under camera calibration, my only choice is Adobe standard. I get the same for me Fuji X100.
In the 6.7 version witn CS6, for my Canon 5d Mark III (same with the Mark II), I had the full array: Standard, Faithful, Landscape, etc.
Have I forgotten something under "camera raw preference"? I included "make default specific to camera serial number".
Thanks,
Marcel

See this link for details on camera support in Camera Raw versions:
http://blogs.adobe.com/lightroomjournal/2012/03/raw-support-in-lightro om-and-camera-raw.html
Snip taken from link above:
You’ll also note that ACR7, available with Photoshop CS6 beta, is lagging the most in updated camera support. This is based on when we lock down or “bake” the code for each release. Even though ACR7 was only released last week it was “baked” before Lightroom 4.0 and Camera Raw 6.7. Similarly, Lightroom 4.0 was finalized before Camera Raw 6.7. We’ll get Lightroom and Camera Raw in sync soon but in the interim, here’s the latest incremental support list for each product, relative to Camera Raw 6.6 and Lightroom 3.6:
Photoshop CS6 beta with ACR7
Canon PowerShot S100V
Fuji FinePix X-S1

What is "Camera Calibration" for?

What is "Camera Calibration" in Camera Raw? Is it for making adjustments to digital cameras to render more accurate color in Camera Raw? Or just for fine-tune RAW images?

because we live in a real world where there are no two things exactly the same and this also includes cameras of course. The profiles are a good starting point but if you find that they don't quite work and get constant blue tinting for instance then you can set those sliders to correct the problem inside the camera. The process usually involves photographing a color chart and then trying to match the colors on screen with the actual numbers

Camera Raw 5.5 will not install? And Camera calibration button question.

I just built a new computer with 7 PRO and installed all my software. So when it comes time to instal 5.5 raw it goes about half way through and tells me to shut off Bridge. As far as I know the bridge window and program are off and not running. I even unpined it off the taskbar.
In CS4 when opening a Raw file and I go to my camera calibration botton there are only two options that come up, Arc 3.3 and 4.4. Where are all the other options at? Do they come with the 5.5 update? Thanks Keig

Odds are you've got Bridge set to auto-launch at startup...make sure it's not running when you try to install the update.,.and yes, the update should install the addition DNG Profile options.

How do I get the Basic and camera calibration sub panels in the develop modual to come back after they go away on there own?

I was working on images and then when I picked a different image the basic and camera calibration sub panels disappeared. How do I get them back?

Right click on one of the other headers and a popup will appear and you can select the ones you need to view.

Probable bug: Camera Calibration

If I change the Camera Calibration setting from Adobe Standard to Camera Landscape (D3s) and then change back to Adobe Standard I don't get the same picture that I started with (in my case I see a red tinge in the highlights). Reversing the change in history undoes the change OK.

Another interesting fact:
When you restart the application after the double change, the red tint is gone. Even when reverting all changes in the history panel and then re-doing the double change, the color are ok for this photograph.
If I move to a new one, I see the red tint again.

Missing Camera Calibration Profiles in Lightroom Creative Cloud

I am missing the ADOBE SUPPLIED Nikon D700 and Olympus OM-D E-M5 camera calibration profiles in Lightroom. They were there until I had to reload the apps from CC. I looked in the forums already and haven't found any answer. I have tried to get support from Adobe through Chat and the person there had no clue what I was asking.
I found this answer on a similar question but it does not explain why the Adobe-supplied profiles are missing. To be clear, I am not talking about custom profiles.
"If you are asking about Adobe-supplied profiles, they will be installed every time you update the software so there’s no need to copy them, anywhere, and the reason for not seeing them would be that the current photo is not a raw file since most profiles are only for raw not jpg."
Can anyone help me out? Thank you.

There is no uninstaller. Just drag the app to the trash and reinstall it from the CC app. That should fix your issue. If you want to know, on Mac OS X and starting with LR 4, the profiles are installed in the app wrapper inside the Applications folder for some reason so they are hard to find. you control click on the app, select "Show package contents" and navigate to Resources > Camera Profiles
