Lightroom and correct color
January 9th, 2008

In the previous article devoted to the Capture One V4, I discussed the problem of compliance colors lightroom especially in warm tones and skin tones.
To start I am not an expert in chromium, or an expert in Lightroom, the contents of this note comes just my observations as a user of RS.
I thought the big difference came from the quality colorométrique Capture One (C1) after performing other "test" with other software processing RAW my conclusion is this.
Lightroom can not get out images with warm tones of red.
The result is the same in Photoshop so has my opinion the problem lies more in ACR (Adobe Camera Raw). The statement comes closer to a real problem rather than a tonal preference.
It may well be that proprietary software type dpp (per barrel) and Capture NX (for nikon) are optimized profiles for the aircraft involved but then explain how that third party software such as C1, Aperture and others manage to make accurate color? According to many post I have read about this problem still affects rendering the warm tones and are all in the same direction without distinctness of material (canon, nikon, km, fuji ..)
I started to do some research on the Internet to see if others have the same problem, after all software as rich and full that LR is not a usable software if it does not comply with an accurate rendering.
I came across some post including this one on the forum at Adobe multiple users equipped with Canon postponing the same problem of respect for warm
Here is a picture posted by one of these users (Andrea Ungaro)
Left with the version generated by DPP (Canon's proprietary software) and right RS version (larger version available here)
Some examples (the images are clickable)
Temperature of 12,400 K
Temperature of 12,400 K
Temperature of 7206 K
Temperature of 6700 K
Possible solutions:
The solution that seems most appropriate is to photograph a Gretag Macbeth chart and then go create your profile ACR via script developed by Thomas Fors.
The procedure is available available on the website Lightroom-news
I have no charter Gretag Macbeth, I have yet attempted to amend the record via the CAB directly to this tool in Lightroom but without success.
It is also possible to engage in selective color correction to try to approach a convincing result but at the cost of working time longer and many trial and error
Some presets corrections found on the Internet for any of the SLR time

Hi Benjamin,
I noticed that my pictures tend to turn to the yellow / orange rather than red in warm tones and skin tones, but I had not gone beyond thinking it was me, seeing your paper I understand why.
I use Lightroom as a library only (I've noticed the yellow cast) and I open my NEF with CS3 directly in Camera Raw and the same conclusion.
Thank you for us to share your tests, given the above example, it is obvious!
January 9th, 2008 at 11:59
Hi Ben,
Photo of dog is blatant, it's true that it is a pity that so mature software that LR is not well calibrated in the rendering of tones, but say it is "useless" is a bit much for me .
I develop on CAB when I was no great series, and I'm pretty happy with the record, I think to make this observation must already have some experience, which are not my case.
Thank you for making us share it.

It's been 3 months that I feel I take pictures constantly yellow, I thought it was from my first relfex the Nikon D80, I just tried to open the same images with Bible and it has have anything! Finally, accurate color! I am really struggling to understand what is happening with Lightroom
January 10th, 2008 at 12:24
For the photo of the dog, apart from the difference of color, I still feel there is a difference in contrast is not it?
January 10th, 2008 at 12:30
phil, yes it's possible I have no way to quantify bilateral contrasts settings
January 10th, 2008 at 12:16
as colorblind, I do not see much difference ...
January 10th, 2008 at 5:15
I made the same reflection was out of Lightroom, which is anything but suitable for people who make the portrait.
I see the flower on canvas portraits oranges, orange sunsets, in short everything is orange and nobody seems to care ...
January 10th, 2008 at 5:26
I myself have the same problem, but there are even more striking, ultra-saturated colors, or fluorescent absolutely does not emerge, as if the high dynamics of these colors fell into nothingness.
A small simple test, a rainy day, shoot a red light, there is no further degradation in the lamp, or even try to shoot ultra violet lights (Tower Tour Exaltis (Mazars) defense) ultra violet colors disappear completely.
That said, I much found the problem in Photoshop as capture (although I feel that this is exactly the same rendering engine!).
January 10th, 2008 at 8:22
The color processing is terribly degraded between my E-500 and my E-510 in CAB. I put this issue back on Olympus with their new sensor LiveMOS. After reading your article I install Olympus Master and there
I find color ... Thanks for the article.
January 10th, 2008 at 9:10
Regarding the calibration script, I found that Rags to more comprehensive and flexible. It allows to use different types of charters and allows the crop and resize, which speeds up the procedure well. Finally, it offers an image of the charter including patches with the reference values for comparison.
http://www.rags-int-inc.com/PhotoTechStuff/ColorCalibration/
After calibration, the report should be colorimetrically neutral. That is to say that the colors of the charter must be virtually identical (100% is not possible) to the baseline.
On the other hand, if the charter is more neutral in Capture One, Capture NX or other, then it is indeed one of these is more correct and thus LR has a problem.
Typically, looking at the charter in NX, we see that adapts colorimetry and this, according to modes. The charter photographed unlike most all-in-fact to the actual charter. The goal here is to make it look more pleasant. It is not necessarily more correct than Lightroom.
While the game is to adapt the HSL LR, after calibration, to obtain the desired rendering (similar to Capture One, NX, ...). I recognize that it is cotton. He is sure the teams or Nikon Phase One are more honed to the task. It is a pity that Adobe does not offer presets also more flattering and more neutral version.
January 11th, 2008 at 4:23
Does your wide gamut monitors are calibrated correctly? I noticed that the warm flesh tones were particularly good in Adobe RGB from lightroom on a calibrated Eizo while they appeared a little yellow desaturated a conventional LCD.
I think Lightroom is simply developed to give its full potential with pro equipment expensive
January 11th, 2008 at 5:01
I did some comparison between DPP and LR with my 5D and I find no glaring differences ... If using DPP made neutral or faithful ... For standard mode privileged saturation of color ... and red ... So has vérfier

Very good synthesis (more on this article PREV)!

Anyway, for 100 euros, I'll take the C1 LE shortly. Unless my old key is accepted?

I do not work that Jpeg for reasons of economies of time and space, and reading your articles make me want to move simultaneously in RAW. J uses a Mac with Leopard system, that you advise me as program development and RAW processing? (S he had no choice in that 1

It depends on your needs and your expectations for my part I am for Capture One V4 Aperture seems also very good too
January 11th, 2008 at 5:39
For me, after long and varied tests (LR, Capture NX, C1, Aperture)
Aperture is really the most ergonomic and easy to use. It is a true Apple product in its ease of learning and results seem very good.
A single defect, it still does not read the nave of the D300 ...

Hi Ben
It is already noted that LR do not always find the same color temperature than CP1. Often, there are strong differences result.
That said, I have always said that LR is nothing but a disguised Camera Raw ...
January 11th, 2008 at 7:13
not disguised at all:
Lightroom is (officially) Adobe Camera Raw ...
mixed with Bridge and iView Media Pro!
January 11th, 2008 at 7:25
Jean Francois
I was reading your post on your blog, you already really opened a portrait with a temperature hot enough in RS and in another Soft to compare the rendering of the skin?
I agree on the landscape photos, photos of dives: LR is great but when you look at the portrait of high saturation or warm colors looking the difference between LR and C1 it falls off his chair !
Done the test opens a portrait rather hot under the two apllis chosen the same hot temperature and compare!
January 12th, 2008 at 8:08
Rest RawShooter Essential, I much prefer to LR or DPP, DPP is the worst I think ...
January 12th, 2008 at 9:18
Why not play on the colors?
January 29th, 2008 at 10:10
There is also an alternative, the famous RawTherapee completely free and gives a development of first class, very close to NX. And then sometimes exceeds Capture One, especially in degraded. But as NX, is suffering, but to lesser extent, a certain slowness.
The candidate C Release 2.3 is available on their forum. Vivemet release the final result.
It has become my second knife from Capture One.
Lightroom just like you Ben, I myself am not at all with its management reporting, and often too risky, relatively speaking, miles away from the perceived reality.
February 2nd, 2008 at 5:03
I also found this problem on all Adobe products images but I managed to solve this problem by selecting the proper size test.
Indeed, by default, Adobe products work by default in a simulation mode rendering to make the best range of colors up the source file. Unfortunately, if the output device (screen) does not have a gamut as broad as the reference profile of the photo (AdobeRGB1998 cons simply for the sRGB gamut of most screens), the display screen will flattened in the extreme color, especially red.
==> To correct this problem, three solutions:
# Either use a screen that can display exactly the same gamut as the gamut of the reference picture. Unfortunately, even with a screen widegammut the gamut of the screen will not stick exactly to AdobeRGB1998 gamut of the picture, there will be another gap rendering "displayed vs. actual.
The gap will still be lower than if we derawtise photo AdobeRGB1998 in Adobe software displayed on a screen classic non widegammut.
# The second option is to limit its network in sRGB. The color space is a bit closer but it is quite sufficient since the labs perform their public prints in this format and all Web postings and other manipulations are made public in this format.
Moreover, not need a screen graphic WideGammut to use this option since most CRT and LCD screens are provided for proper bonding to the sRGB standard. Thus, even when using software that can not handle color profiles, the display will be correct if our entire chain is sRGB (source files in sRGB, sRGB classic screen, printer or shooter in sRGB).
# The final solution, the most serious and academic, is to not display photos with the test mode by default Adobe. In fact, when developing and editing his photos, you must manually select the test format that fits the profile of the screen depending on the gamut that can display. Thus, software adobe will adjust the colors of the display function that can display the screen, even send up some color saturation that the monitor can not display as far as the reference profile of the photo .
With this method, we can correctly display any picture (regardless of its reference profile) n'importequel type on screen (provided it has an associated color profile).
Unfortunately, such methods need to have a specific profile calibrated to the screen (and therefore reflects the gamut displayable).
=> It is only with this third method requires a calibrated profile that will display a rendering of compliant and calibrated with the Adobe software. Unfortunately, I do not understand is that this type of event (the monitor) is not enabled by default and must be changed manually while dérawtiseursdes Other publishers include many default .
This could be explained by the fact that the method of test format by default Adobe works best with monitors that do not have a specific profile but to the "experts" who calibrate all their displays, it is quite tedious having to change the profile test each time to have a consistent record.
February 3rd, 2008 at 4:07
Regarding the comment before, according to my understanding, I want to clarify things 2-3.
The test mode (soft proofing) is not there to correct the display screen, but to simulate an exit.
For example, using the profile of a paper to a printer, you can simulate the loss of saturation, contrast, color paper ... and make corrections so that the output looks as much as possible to the image of origin on the screen. The quality of the profile depends directly, quality proofing. Printing too of course.
This function is expected in LR but exists in Photoshop. This avoids the impression "to try".
On the screen, when you create a profile for it with a probe, it is used by the operating system (or earlier Adobe Gamma) to adjust the color space of the image displayed in space color screen. Again, depending on the profile quality and capabilities of the screen, the result is more or less good.
For more information these and many other things, I suggest you watch the video From Camera to Print an excellent site Luminous Landscape:
http://luminous-landscape.com/videos/camera-print.shtml
February 3rd, 2008 at 6:09
I think many know whereof I speak, hence my misunderstanding of the behavior of adobe software for posting photos.
By default, this is the only software that does not display them correctly rendered taking into account the calibrated profile, and yet they do not use the overlay to display the image (because the overlay does not pass through the profile color as the OS loads at startup).
As I made clear, the only way not to have different colors afichées with a calibrated screen in Adobe software is to "force" a test format that matches the screen ... even if originally This may not be provided for that.
February 3rd, 2008 at 7:37
IntruX, my intention was not to suggest that you do not know what you're talking about.
Can you give me any source that would help me understand why PS does not soft proof for the screen by default. I never had the opportunity to read a book or an article that explains it. Thank you in advance.
Currently my small chain graph is configured as what I have learned after several sources. Unfortunately, I never had the opportunity to read this type of setup does not allow the optimal display performance. Unfortunately (2), it is not applying it to Lightroom.
February 3rd, 2008 at 10:05
Ben I have no specific links to give you but you will surely find hundreds looking on google. Many users have a different view in Photoshop and apply the format appropriate to the test screen to have a consistent display. That said, in my box using Adobe CS2, maybe other versions allowing a permanent test format.
Otherwise, the most convincing to verify my statements is to test yourself: you will find that the display of any photo in a photo software adobe will not consider the profile of the calibrated screen. The image will be displayed differently than other software images, or in the office envirronement if it has a loader profile "at startup (such as" Adobe Gamma "for a profile done by hand, or" LacieLoader "for a probe Lacie, etc. ..).
By cons, if you apply the test format that matches your screen, you will find the same record as in any other software.
February 3rd, 2008 at 10:35
IntruX confuse you monitor profile and output profile. The soft proofing is used to simulate a test print and not to see the profile screen that is already active by default through the system.
I've never had a soft unlike the other both MacOSX and XP.
If you display the soft proofing with the profile of your screen, everything is distorted.
February 3rd, 2008 at 11:13
IntruX on my Mac, I have no difference whatever the soft.
As for the link, I have already begun to seek and share read what I already knew and that reinforces my setup, I have nothing to invite me to try the soft proofing display. Especially since you can earn and use the soft proof in evaluating an output function.
I had the opportunity to read several books and articles reviews (Bruse Fraser, Amadou Diallo, Martin Evening, Michael Reichmann, ...). No books colorimetry specifically, it is true, but none raised the issue. It is sure that this does not make me an authority on the subject and I can very much misunderstood, so I wanted a link explaining it.
February 4th, 2008 at 2:41
Exactly, the "monitor profile" is not enabled by default in photoshop unlike all other applications.
Or maybe Adobe has changed its operation from PhotoshopCS2.
In fact, my job, using CS2 and it is the designer of my box that made me notice that I had to select the aspect of my screen test for the picture appears correctly as in the 'desktop environment or other software.
At first I tank because I thought that with the implementation of a loader at boot time, there was no need to change anything in Photoshop for the rendering to be calibrated. Unfortunately, I found that this was not the case with Adobe products.
Then, the designer of my box that is propped particulièrmeent in this domain explained the most serious photo software bypass the monitor profile loaded by the OS to implement their own system. Thus, in captureNX, if desired, you can choose a different monitor profile even if the default is the same as Windows is loaded.
The difference display Adobe products by default compared to other programs, it is not visible when working on images in standard sRGB, by cons it becomes obvious on images AdobeRGB1998.
==> I invite you to take the test then is that when you treat my graphic box liars
February 4th, 2008 at 3:27
But of course it active, removes it and you vera Unlike gamut, white point, black point and other dominant.
I bump into the studio for over 15 years, I never used the soft proofing, like in any photoengravers I know.
The soft profing only useful when your profile image (dedicated to printing) does not match the output device.
In short you are doing wrong ...
February 4th, 2008 at 12:10
Nan, nan
My colleagues are like that all their photos they then integrate into their websites (I work in a box that makes webdesign). If they do not work based rendering with "color test" in photoshop their pictures are different from what will appear in the envirronement office in a web browser, or on the client machine.
I know what I mean. Moreover, seen as you assert, is that you did not test what I say. I guarantee that by default, photos are displayed differently in Windows and Adobe software.
At no time do I change the reference space or the workspace of my photos. I only specify the Photoshop monitor profile. By default, the "Proof Colors" are RGB / Windows and need to switch to RGB / monitor so that the picture appears correctly as they appear on any other computer.
In fact, I do not think the software do not adobe Profile calibration screen by default, I just think they use it differently, hence the necessity to see the result in "colors of tests "for this match with the rest of the envirronement office or other software files.
Then we might yet another record display to simulate a print rendering, but that's another problem.
==> Too bad for you if you do not believe me, it will only penalize you in how you use Adobe software.
Presonnellement because I do not really think LightRoom or interpret the CAB files with less red. ... They just show them the wrong way because the screen LKV uses a calibrated monitor profile.
Moreover, it is not only the red is less intense, they are ALL the colors that are flattened except that it shows especially in the red (as shown on the example of LKV with the dog, it is clear that green grass is also less intense).
February 4th, 2008 at 8:59
It's not that we believe you. We asked you about our experience, for my part, it is in the field of advertising and printing pro.
I know that many users have trouble with Windows profiles, among other pcq they do not disable Adobe Gamma with their probe.
Me, I have zero problem. Under XP, my chain graph is flawless. Both the viewer under XP, only in Photoshop, Capture One, RawTherapee or NX and others.
For the red CAB, LR and yes, it's his motor development. The temperatures are not at all with the same soft sharp. Nothing to do with the display. For proof, look at the screen of Ben, you're in a browser and not in LR, and yet the differences are obvious while having the same profile
February 11th, 2008 at 2:42
And your lab, he works with what profile? and leaves the impression that it is how? The chemistry, you know your chemistry lab brol brol machine or bazaar? We pariri albeit with the same profile, you will have the same paper to two different tests, we test?
February 11th, 2008 at 10:46
Obviously we have different impressions of one lab to another, even on the same machine type with the same profile.
It is simply because the machines are rarely calibrated properly. First by a technician who knew his business, with the second material need probe, charter etc ...) and third 1 time per month.
February 12th, 2008 at 11:31
no attempt so far Gam just think the chemistry machines, forget your two minutes and calibration technologies brol your bazard ..
Go to a lab, go back a week later or two, I bet you'll never twice the same image, perhaps it will be very close, but not ideetiques ...
To get the same print run should be identical chemistry, a Emulti identical, similar exposure not change even half a second ...
Far outside the labs continue to use paper money for the printing of papers is a link in the chaînne rarely addressed.
Unless you have your own digital lab (including printer so) it is impossible to control all pramètres ...

Hello, very interesting about this Ben. I too found this problem in mind the only one. Finally this is not the case

I just bought adobe photoshop elements and I perceive the same problem. It uses Camera Raw 4.2 for processing raw files.
So I'll continue to use Capture One LE for deRawtiser my photos, which offers a good compromise

Intrux The comments are very interesting, but I think there is enormous confusion-confusion -
As he said himself he bump into a box of webdesign and graphic of the box using this technique (in a soft proofing toshop the profile of the screen as output profile) to see what will the images in a browser .
This technique is actually perfect, but just to see what gives an image in a browser that can not handle the color. (Except for ages safari and firefox 3 beta I think). That's what these designers seek, and they are right to do this.
It's exactly like that with a profile of printing (I always do that but with my print profiles or those of my lab)
Now, in photo, (it does not intend to use Web) and use a calibrated screen in photoshop, this technique is worth avoiding! It only allows to see what will display an image without color management ON ITS OWN COMPUTER (on everyone else, this will be different, it is no secret if you want the same display, you need a calibrated screen AND a soft managing the color management)
PS : il ya souvent une confusion avec les profils couleurs écran : ceux ci comportent deux parties, la première, les courbes de gamma qui sont chargées dans les LUT au démarrage (via un bootloader sous windows ou via colorsync pour OSX).
=> c'est donc une correction de la couleur effectuée au niveau hardware. Elle permet d'atteindre la T°de couleur et le gamma choisi lors de la calibration
La deuxième partie est un profil icc standard qui caractérise l'espace couleur de l'écran, son gamut. La sonde permet d'établir une cartographie qui permet de corriger en gros des déviations de couleurs particulières. Grâce à cette deuxième partie, on affine encore la justesse des couleurs.
=>correction effectuée ensuite au niveau software uniquement par les softs gérant la couleur. (photoshop en fait partie, un navigateur comme internet explorer non.)
Et quand je dis gérer la couleur, je parle d'un soft qui gère à la fois le profil de l'écran (cette fameuse deuxième partie du profil, différente de ce qui est chargé au démarrage) et le profil de l'image (adobeRVB, sRGB etc….).

Je viens de faire quelques essais comparatifs à partir de fichiers Nikon .nef, ouverts avec les réglages par défaut et exportés par Lightroom et Bibble Lite.
Résultat des courses :
- photos 1 et 2 (mer et falaises en fin de journée) : rendu plus flatteur (+ rouge) chez Bibble
- photo 3 : coucher de soleil : mieux chez LR où le soleil est une orange que Bibble où le soleil est tomate
- photo 4 : maison en pierre éclairée par soleil couchant : mieux chez LR, forte dominante magenta chez Bibble
- photo 5 : gros plan de fougère fanée en début de journée : plus flatteur chez Bibble, mais plus subtil chez LR
- photo 6 : branchages au coucher de soleil : LR affiche un histogramme qui ne va pas jusqu'au noir, contrairement à Bibble. Une fois les noirs montés dans LR, diagnostic idem photo 5
- photo 7 : bateau échoué, lumière après coucher de soleil très douce : Bibble plus saturé et noir, LR donne une interprétation plus naturelle
Conclusion arithmétique : match nul.
Conclusion photographique : les photos pour lesquelles Bibble était meilleur n'étaient pas dramatiques dans LR. Bibble au contraire abime deux images.
Là où l'on pourrait reprocher à LR sa dominante jaune, on pourrait reprocher à Bibble sa dominante magenta.
Le parti pris de LR semble être plus neutre, alors que Bibble favorise un développement plus flatteur (idem minilabs).
Ce qui me parait important, c'est que les raw (en tous cas ceux-là) développés dans LR donnent plus de latitude de travail que ceux de Bibble : c'est toujours plus facile de monter les densités que de les descendre.
