Starting profile for ColorChecker calibration in PE

Hi
Making profile calibration in Profile Editor with the GM ColorChecker I noticed that the original profile is always set to ColorChecker. I supposed there is anyway a original profile to which the calibration correction shift is applied to obtain the final profile to save. Is this "starting" profile the latest ACR 4.4 profile used in ACR or some other? In the PE FAQ page this is not detailed.
In fact I suppose the PE calibration is making only a "relative" adjustment related to a initial profile color characterization.
Thank You to anyone can give an answer.

Not exactly sure what you mean.
The Chart Wizard-generated profiles are intended to be fairly accurate from a scene colorimetric point of view, within the technical limits of the method. Any additional adjustments based in Camera Raw (i.e., beyond the defaults) are essentially "rendering" choices made by the photographer on top of the default color rendering provided by the profile.

Correct.

There are 2 sets of color tables in the new DNG 1.2 profiles. The main distinction is that one is 2.5D and takes place prior to exposure compensation, whereas the other is 3D and takes place after exposure compensation.
Profiles generated from the Chart Wizard only impact the former type of HSL tables (i.e., 2.5D) and do not contain the latter type of HSL table (3D). This is in keeping with the idea that Chart Wizard profiles are designed to provide fairly accurate scene-referred colorimetric estimates.
In contrast, Camera Matching profiles only used the latter type of HSL table (3D) but do not use the former type of HSL tables (2.5D). This is consistent with the idea that CM profiles are designed with specific output-referred effects in mind (e.g., lightness-dependent hue twists).
In general, the rendering controls in Camera Raw which affect tone and color take place __after__ the profile is applied, so you can think of these adjustments as being placed "on top of" the default rendering provided by the profile.
So the profile is a starting point and then you can adjust brightness, contrast, etc. relative to that baseline.

JSPM: Error while detecting start profile for instance with ID _c.

Hi Experts,
we have an error when we start JSPM with message "cannot initialize application data. Error while detecting start profile for instance with ID _c." . Until now nothing has been updated yet. The system can be started up and shut down without any problem. The profiles are found in /usr/sap/PMA/SYS/profile
Our BI system is currently Netweaver 7.0 with SPS14. We plan to update it to SPS20. But when we start JSPM, we have abover error.
could somebody give a help? Thank you very much.

Where should I save the camera calibration profile for Lightroom 2?

I created some DNG Camera Profiles by DNG Profile Editor. For Camera Calibration in Camera Raw, I save those .dcp files in C:\ Administrator\ Documents and Settings\ Application Data\ Adobe\ Camera Raw \ CameraProfiles. However, I could't find such a subfolder in Lightroom folder, does any one know where should I save the dcp files for Lightroom 2? Thank you

It's the same install folder for both Camera Raw and Lightroom (i.e., a .dcp installed in the folder you described will be readable by both CR and LR).

Which Camera Calibration Profile for Leica M8 with LR3?

I see there are 4 camera profiles for the Leica M8 that all produce significantly different results - ACR3.6 and 4.4 and Adobe Standard and Camera Standard. Any advice on which to use and when?
Thanks in advance.

ACR 3.6 (this is the Adobe standard profile) when support was first introduced.
ACR 4.4 (with this version of ACR) Adobe created an updated standard profile.
Adobe standard, this is the latest profile introduced during ACR 5.x, just a new naming method
Camera standard, this is a profile created by Adobe to simulate the profile by the M8 to produce in camera jpegs.
Use the one that pleases you most, as a starting point then create your own presets to make further adjustments.

Missing camera calibration profile for supported camera

I am relatively new to Lightroom. I have imported Panasonic Lumix DMC-FZ200 raw (.RW2) files into Lightroom 5.3. When I go into the Develop module under the Camera Calibration the only profile that shows up is Adobe Standard. My camera is supported according to the Adobe web site. What gives?

Bob, like the above post mentioned, I am also fairly new to Lightroom and still learning a lot of how things are suppose to work. I'm sure my problem is similar to the above post but can you please clarify this for me one more time. In my case...
I use a PC running Windows 7.
I'm running Lightroom 4.4.1, Camera Raw 7.4
I import photos from a Pentax K20D camera.
In the "Develop" module under "Camera Calibration" I only see 4 profiles which are "embedded," "ACR 4.4," "Adobe Standard" and "Camera Standard."
Is everything correct? Am I suppose to see a camera profile for my Pentax Camera? If so, how do I properly install a camera profile for my Pentax K20D camera?
I followed the path C:\ProgramData\Adobe\CameraRaw\CameraProfiles and I found the "Adobe Standard" folder and in there where tons of camera profiles. I also found the camera folder and it had also different camera model folders in there including my Pentax K20D, however nothing shows up in Lightroom itself under camera calibration.
Can you please clarify how all this works? Thanks!

Please help me find a color profile for Samsung 2343bwx

Hi Everyone,
Im just trying to get started in the graphical design field, I just bought a Samsung 2343BWX Lcd monitor (i know I know TN isnt the best for graphical design but im not rich), the color profile that came with the monitor is defective and displays everythign in a deep yellow tint, Ive tried using samsungs Natural Color Pro monitor profiling software but it results in a really ughly profile that is too dark and has a blueish tint to it.
Samsung's support isnt much help (no sprise there) and I cant afford a spyder or eye-one hardware calibration tool at this point.
Does anyone have or know where I can get a good color profile for this monitor? You have no idea how much I would appriciate it.
Thank you in advance for your help
All The Best

You have a few choices....
1. Use the generic monitor profile supplied with your monitor, the one that came with it when you bought it. This will be generic, and will not account for drift, and probably won't be all that accurate. But, at least it should be in the general ballpark since it represents a cross section of a grouping of similar monitors.
2. Try one of the presets that came with your monitor. I don't know what presets or controls are offered with this monitor, but I would shoot for a color temp between 5000K and 5500K, a 2.2 gamma, and a reasonably dim brightness setting.
3. Find someone who can do a hardware/software calibration, either a friend, or someone who will do it for a fee. This will get it right once (if they know what they are doing), but will not account for drift over the long term.
4. Search online and see if you can find some visual calibration target and do it by eyeball. This is usually not easy to do, and probably won't be satisfactory, but you can give it a try.
5. Buy a calibration package and do it yourself. You should probably calibrate an LCD monitor at least monthly (I do mine weekly). This is the best way to go, at least if you are serious about accurate color. And this doesn't guarantee that your monitor and print will match. For that, you need to calibrate your printer for each type of paper you use, or rely on generic printer profiles. Then, you have to make sure you set everything up properly and utilize all your profiles properly. Sorry, but this is all part of the price you have to pay if you want good color.The fee involves money for the proper tools, education on how to use them, and experience in applying them properly.

The factory profile for this display could not be found

Just received a new (mid-2012) macbook air (13"). Started it up from time machine from my old macbook pro.
The new screen seemed a bit blue so I thought I'd calibrate the display. But I don't seem to be able to. I don't get the Display Calibrator Assistant. I just get 'The factory profile for this display could not be found'. Please help if you can?

Thanks for the feedback.
With Pacifist, a search should show everything in a separate search results window. That feature might only be available in the paid mode. If you're reinstalling once a month, you might reconsider how you're using the machine. If you made frequent bootable backups/clones to an ext FireWire HD and also did a Time Machine backup to another disk/volume/partition, you'd probably minimize doing that. I haven't done an A&I installation but once the past six years. That doesn't include purposeful ones done while beta-testing Panther, Tiger, and Leopard.

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,

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...

Lens profile for Leica Summilux 50

When I run lens profile downloader, and select Leica from the lens manufacturer dropdown, I don't see any Leica lenses listed. I read elsewhere that there is a profile for this lens, yet I don't see it in the profile downloader.

Adobe probably doesn’t have one because I believe this is a manual lens.
A lens profile is a file that contains a series of corrections that are matched to various combinations of: focal-length, aperture and focus distance. This lens is fixed focal length, so that’s 1 of 3 parameters that are known, but unless the raws from the camera contain aperture and focus-distance data then a lens profile isn’t very precise and the profile matching can’t take place automatically.
If you want you can try making your own profiles using the Adobe Lens Profile Creator—search Adobe.com for the program, and see if you can get them to work. Besides the program you’ll want to print out the checkboard calibration target at a known size on a laser printer.
Start by shooting the series of images of the target for just one focus distance and aperture and see if that profile works. If so, then do some more for various apertures and focus-distances. If the info is not stored in the raw files then you’ll want to make a series of profiles and match them manually, yourself after recording what the aperture and focus distance were. If your camera is one that records an aperture value but it is just a guess based on a front-facing photocell on the camera body, then this could be wildly wrong so the corrections may not be that close.

Raw 3.1 professional custom profiles for highend digital cameras

I have a few questions for thomas knoll:
I would like to start with a statement here:
WHY ??? ....all this messy color calibration with slider inside the raw 3.1 plugin , when it could be so easy and simple :
what you can find already inside high end digital back software like sinar's capture shop or the leaf capture software, is nothing more and nothing less than a plugin called profilemaker , written by greatg mac beth. the leader in this field nowadays.
a software ,which again against license fees, is being implemented in those softwares.
what does it exactly do?...you might ask....
well, here a very simplified explanation :
for ex., you start your shoot with a shot of greatg color chart (24 patch or the big one), and that very" licensed" plugin called profilemaker will calculate a 100% precise and accurate color correction in the form of a custom icc-profile for you.
in just a few seconds.
so that that red from the chart that you took a picture of, is going to be that very same red in the final file in photoshop.
it puts something like a correction curve over your original raw file, so that it matches that very color from chart you just shot.
such colors is a game of numbers and formulas, and certainly not a slider function to fumble around with, where one person will say this red is correct, and another says no, this red is the right one.
something like profilemaker is incredibly accurate , because its pure mathematics, and not a form of lottery...!!!with an infinit number of possibilities when one would use sliders like in raw 3.1..
sliders that fighteach other, especially the ones in the calibrate tab section.
it takes a few second for a profilemaker software to make an 100% acurate custom color correction , in the form of a custom icc profile for your shot / and or digital camera.
if you have ever experienced this shortcut and these amazingly beautiful rich colors you can achieve with such a software, you will NEVER EVER go back.
I am not sure why adobe has not come up yet with their "own" version of such a profilemaker portion inside raw plugin 3.x.
they certainly have the know how to do this.
i would dare to state here, that it probably would take them only a few days to implement such a feature.
or , why adobe is not implementing an optional upgrade with "gretags" profilemaker , inside their raw plugin.
I certainly can count hundreds , probably thousands of photographers, who would be more than happy to pay for this feature. even if the license fees would be above 300$ for such an upgrade.
dear thomas knoll,
why have you not yet done so.....>>???
I hope that very, very soon you will consider such a suggestion.
in the meantime ..............i cross fingers......
very sincerely,

I have done many DlogH curves, and at one point, owned the Zakia /Todd book. No, the toe does not change much with increased development, but it does change. And yes the changes beyond middle gray (Zone 5; 18% gray)are greater than below, but again, it does change. Film speed does change as a function of development, and film speed is based (variously over the years) on just how the film comes out of the toe, it is inescapable that the curves pivot about the toe, roughly speaking, that is. The curves not only pivot there, the toe can increase in F+F value thereby showing a vertical displacement on the plot. If you take individual plots of a particular film over differing development changes, and overlay the curves such that the toes merge (roughly!), you will see that the slope of the curve does rise from the toe. I have lots of graphs in storage if you would like to see them.
I am familiar with AA's procedures. I studied and used them from about 1961. One of the reasons I ran so many curves is that I was interested in the so called compensating development, such as water bath, special formulas etc. I ran the curves on Plus-X, Tri-X, Tri-X professional, Panatomic-X, and other emulsions whose names I have forgotten. What I found out is that Plus-X didn't respond to compensating development at all. I could lay the reference curve over the DUT and they would match exactly. Quite a shock. I remember a film rated at ASA 250 that responded admirably, but way too grainy, even in 4x5.
I used two methods. One was to contact print a step tablet, the other was to shoot the tablet using an old diffusion head as a light source. I could tell how much support in the shadows I was getting from flare that way. Oh, and the one way that always worked was pre-exposure, sometimes post exposure. I could lift the toe nicely that way.
Plus-X had the straightest middle section of all. Ruler straight. Tri-X had a significantly different toe than Tri-X Professional.
Every meter measures luminance and can allow you to measure the scene dynamic range. A one percent spotmeter becomes an averaging meter for extreme telephotos, just as there is no such thing as a panoramic camera with a fixed lens. It's just cropping for the panorama, and whether a handheld meter is averaging or spot depends on the relative focal length of the taking lens.
The idea that a hand held averaging meter cannot give you the dynamic range of a scene is nonsense. Have you ever read "The Negative", first edition of AA? He explains how to use a meter to obtain dynamic range, if you cannot do that, you cannot even begin to use the zone system. He even described using a tube set into the meter element to do a rudimentary spot meter. I had several Weston Masters which had this homemade accessory. it was pretty neat, but boy, did it rob you of sensitivity!
Look, a metering system is simply some sort of light sensitive material which provides a change in some electrical parameter for a corresponding change in the light level. On it's own, you would simply see a needle move across the face plate. Putting numbers on the face plate corresponding to some light unit (Lux, Ft. Candles, Candles/ft^2, etc) allows you to quantify the responses. What you ultimately do with these numbers is one of the biggest parts of sensitometry as applied to photography. As you say, that application to digital is different than to film, but only because the demands of the digital medium requires it. I could just as easily build an exposure system for film based specifically on highlight placement. Film chose a different route, and, so far as I can tell, the optimum route. If digital and film had developed concurrently, perhaps we would reconcile the two systems so as to avoid the condition we find ourselves, at least those of us raised on film. The new guys, well, they will probably chortle over the Dodge/Burn application. They will have no appreciation for negatives. It took a while in the darkroom with the counterintuitive nature of dodge/burn when I started up.
I am enjoying this exchange, Jeff. It clears the air, and reminds me that in order to most easily grasp the digital concepts, I am better off with my engineering hat than the photographer's hat. I'm in my late 60's and it's too easy to slip into old patterns. Changing hats works well, and I am glad I can do it.
Cheers, and goodnight! (my,oh my! It's 1:17AM here!)

Camera profiles for Sony A700

Hi,
I'm working in CS4 (Mac) and I downloaded the latest camera raw 5.6. I have only the Adobe standard, ACR 4.4 and ACR 3.5 in the Camera Calibration -Camera Profile.
I don't see special camera profiles for my Sony A700. In tutorials they showed profiles for Canon or Nikon. How can I get the profiles for the A700? Do they exist?
Thanks a lot
Claudine

Hi Claudine,
At the moment these are the only profiles made by Adobe for the A700. You can build your own profiles (or edit existing profiles) using the free DNG Profile Editor, if you wish. Another solution for a custom profile is the ColorChecker Passport, from X-Rite.

Lens profile for Leica 24mm f/2.8 Elmarit

I'm looking for a lens profile for the Leica 24mm f/2.8 Elmarit lens. I see that Adobe doesn't have one, but if anyone has made one, or can give me some suggested corrections, would be appreciated.
Thanks
William

Adobe probably doesn’t have one because I believe this is a manual lens.
A lens profile is a file that contains a series of corrections that are matched to various combinations of: focal-length, aperture and focus distance. This lens is fixed focal length, so that’s 1 of 3 parameters that are known, but unless the raws from the camera contain aperture and focus-distance data then a lens profile isn’t very precise and the profile matching can’t take place automatically.
If you want you can try making your own profiles using the Adobe Lens Profile Creator—search Adobe.com for the program, and see if you can get them to work. Besides the program you’ll want to print out the checkboard calibration target at a known size on a laser printer.
Start by shooting the series of images of the target for just one focus distance and aperture and see if that profile works. If so, then do some more for various apertures and focus-distances. If the info is not stored in the raw files then you’ll want to make a series of profiles and match them manually, yourself after recording what the aperture and focus distance were. If your camera is one that records an aperture value but it is just a guess based on a front-facing photocell on the camera body, then this could be wildly wrong so the corrections may not be that close.

Do I need to set AI colour profiles for use in ID?

My previous set up:
Mac
CS2 (Illustrator, Photoshop, Bridge)
Quark XPress 7
My new set up:
PC (Win 7)
CS5 (Illustrator, Photoshop, Bridge, InDesign)
My problem:
I work for a company that prints newspapers, but my dept also does work for glossy sheetfed printers (magazines leaflets etc)
All my work is exclusively CMYK.
With my previous set up - I didn’t want to have to switch my colour profiles via Bridge as I was constantly juggling two types of jobs:
Our tabloid press - Profile - ISOnewspaper26v4 (CMYK)
Sheetfed Printers - Profile - ISO Coated V2 (Fogra 39) (CMYK)
So I set my CS2 Suite colour settings to ISO Coated V2 (Fogra 39) and set an action in Photoshop to convert jpegs / eps photos to ISOnewspaper26v4.
So my CS2 working space was set for Sheetfed glossy publications and if I wanted to set a picture to the correct profile for newsprint I just had to open the picture and hit the action that applied the ISOnewspaper26v4 profile.
Regarding Quark – I set up separate templates for each type of job:
One for Profile - ISO Coated V2 (Fogra 39) and one for - Profile - ISOnewspaper26v4.
Regarding Illustrator - I found that Quark 7 didn’t differentiate between Illustrator colour profiles, or if it did, it didn’t show up in ‘Usage’.
If I went to Quark Usage and went to ‘Profiles’ it only listed the Quark profile and any Photoshop profiles, not any Illustrator profiles.
So in Illustrator I just set colour profiles to ‘do not colour manage this document’. So that I only had to worry about changing profiles for Photoshop jpegs / eps’s.
So I had a good little system going that served me well and now my company decided to move us to PC’s and CS5; and I still have the same problem – juggling newsprint jobs and glossy magazine jobs and not wanting to have to synchronise my CS suite colour settings every time I switch between jobs...
So I was hoping to stick with my little system on PC / CS5.
So basically my question is, do I need to worry about Illustrator colour profiles if I am bringing Illustrator files into InDesign? (To clarify, my Illustrator files are always pure vector, so there is no chance of some rogue RGB jpeg sneaking through on a Illustrator file)
Im open to suggestions regarding my set up, but really would prefer not to have to keep switching my colour profiles.
Any help would be greatly appreciated.

First, I wasn't suggesting that your PDFs be exported to RGB, but it is a common workflow these days to keep photos in RGB until you convert them to the correct profile during the export process. This maximizes the potential for re-purposing your documents and allows you to use the same RGB photos for different output purposes without having to do separate CMYK conversions for each destination, so long as you don't need to do any tweaking after the conversion.
And to answer your question, if the .ai files have no embedded color profile they will ALWAYS be considered to use whatever the CMYK working space is in your ID file, so the numbers will be preserved. This means that there will be slight differences in color on output on different devices (the whole point of color management, after all, is to preserve the appearance of colors by altering the numbers for the output device).
Does the vector work you get from Thinstock come with an embedded profile? Is there any color that is critical for matching, such as a corporate color (which should be spot, but that's a different discussion), or do you use the same art in both the newspaper and magazine, and does the client expect a match (which we know isn't going to happen anyway)?
If there's no embedded profile when you start, there's no way to know what the color was supposed to look like, so color management is not possible, really. You can assign a profile, but you'd be guessing. Since the correct appearance at that point is unknown continuing with out color management shouldn't present a problem. The only case where you would need to manage the vector art would be if the color APPEARANCE is critical or you need it to match across different outputs, and in that case you would need to assign a profile and allow ID to preserve the profile on import and remap the numbers, which means you would likely get rich blacks someplace. Since it's unlikely that you can get a good match going from glossy to newsprint, I probably wouldn't even try -- you wouldn't want, for example, to tag the art as newsprint, and have it print subdued on the gloss if it would look better or more correct with the other profile. Color management would be much more useful if you were going from sheetfed to web on the same stock.

How can I get access to my user profile? do I need to createa new Administrator account? Please help
The EventSystem sub system is suppressing duplicate event log entries for a duration of 86400 seconds. The suppression timeout can be controlled by a REG_DWORD value named SuppressDuplicateDuration under the following registry key: HKLM\Software\Microsoft\EventSystem\EventLog.

hi do the following
1. In Search programs and files (Windows 7) area, type in regedit, and press Enter.
2. If prompted click yes,
3. expand the following HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
4. click the sid that related to your admin profile (if you not sure, click each sid and in turn look to the right hand side of registry editor it will show who that sid is related to one of the registry files should hae in description localhost\admin or
something similair)
5. right click the sid and press delete.
6. restart your machine and log back on with the admin account, this will then rebuild the admin profile... dont worry when it loads and none of your personal settings are saved or files or folders... go to c:\users
in here you will see two folders for the admin account, one will be just admin and the other most likely admin.localhost
i cant remember which one is which but just check both, one will still have all your files and folders in it.
i suggest making a backup of your data before doing this incase something does go wrong, but ive had this happen many times in a domain enviorment and has worked for me everytime.
