Integrate DNG Profile Editor with Lightroom

Worthy of an official feature request, me-thinks...
Its a great tool that's under-utilized - why not integrate it with Lightroom?
Some ideas:
- Dis-associate it from the DNG file format, so it does not need an intermediate DNG file to transfer a profile to a proprietary raw. (for those of you who dont know - you need a DNG file for initial profile creation, but then Lightroom can extract it and apply it to proprietary (non-DNG) raws.
- Make options in Profile drop-down menu in Lightroom:
- Edit Profile
- New Profile
- Delete Profile
I think these ideas would be relatively easy to implement. Maybe Lr4.
Other ideas that would probably be harder to implement, but would also be worthwhile in my opinion:
- Make a color editor based on the DNG Profile Editor technology, that allows one to fine tune color without a profile and copy/paste/sync it like you can do now with HSL adjustments - including saving with presets. Maybe Lr5 or 6...

Hi, I converted a Canon CR2 from a Rebel xti (or 400d) to DNG.
Good news: I've copied the same DNG file and the same copy of DNG Profile Editor onto a computer running win vista sp2 and it works like a charm! I got the message "Canon EOS 400D 100iso_day_curve2.dcp was exported successfully". The profile was saved on a wrong folder: somewhre in the adobe tree but not in the camera profile folder (in this computer is C:\Users\Fernando\AppData\Roaming\Adobe\CameraRaw\CameraProfiles\).
So I think it is a win xp related problem.
I've noticed another problem in both machines (xp and vista): In the "Color Tables" tab the RGB, Lab and HSL number displays only two digits. The biggest rgb shows 55, instead of 255.
Good luck

Creating profiles for special illuminants in DNG Profile Editor

I have successfully used the DNG Profile Editor with images of the ColorChecker Passport to create simple dcp profiles for daylight and tungsten illumination. I have obtained very satisfactory profiles using both a single image and the "both color tables" option, as well as two images (one tungsten and one daylight) and the "dual illuminant" method.
Now I wish to construct separate profiles for use with unusual light sources: fluorescent lights and white LED lights. Can some one tell me how this is best done using the DNG Profile Editor.
Appreciate any suggestions.
Mike.

When there are two illuminants in a profile ACR will interpolate an effective profile based on how far the actual image WB is from one of the illuminants in the dual profile. For example if the profile is using the 2650K (Tungsten) and 6500K (hazy sunight) as the two illuminants and your images is taken in direct sunlight with a WB of 5000K then the profile will be more the D65 profile but a little bit of the redder A profile mixed in. This allows the dual profile to be used for any lighting with a Temperature between A and D65 that also has a Tint number close to or a little above zero. An A/D65 dual profile fails for fluorescent lighting because the Tint number is quite a bit different than either the A or D65 Tint numbers.
To your question, for a single illuminant profile, you should use the Both Color Tables option so that no matter what WB your photo has, the profile used will be the same. This makes the illuminant A and D65 irrelevant because any interpolation between the two illuminants would result in the same profile numbers.
However, I also think that the dual illuminant numbers are not necessarily hard-coded to A and D65, at least not when you use the CCPP plug-in for LR to create the profile, but are actually whatever your photos WB numbers are, so you can make dual-illuminant profiles for other pairs of lighting, such as fluorescent and daylight or fluorescent and incandescent, or even sunlight and shade, depending on what mixed lighting you have at your location and time of day.
An easy way to test this would be to make a dual profile, one DNG being fluorescent and one being your blue LEDs (two sources far away from A or D65), then also create two single profiles, one for each of those same two lighting sources. Test the dual-illuminant profile with the fluorescent CCPP image, and then switch the profile to the single illuminant fluorescent one and see if anything looks different. Do the same test with the blue-LED CCPP image with dual and single blue-LED profiles.
If the look of the image is the same when using a dual profile where one end is the same as the single profile both tested with the actual CCPP image that was used to make the profile or one end of the profile, then the illuminant numbers in the dual profile change to whatever the DNGs illuminants were. However, if the look changes between the dual profile and the single profile when applied to one of the dual-profiles image's WB then the illuminant numbers must be fixed to A and D65, and so any dual profiles are useless if the two illuminants do not match A and D65.
If your experiment fails using the DNGPE, then try it using the CCPP software and the LR plug-in.

DNG Profile Editor not working with new Profiles from LR 3.6?

I'm noticing that DNG Profile Editor is not really able to work with profiles from newly supported cameras, like the X10. Apparently the profile spec has been updated. Has DNG Profile Editor been abandoned or will it be updated to work with the new spec? I really hope it is!

Thanks. I am looking forward to editing the v4 profiles for the D700 - I just want to change a few colors in the existing profiles. I think the existing v4 profiles do an excellent job of matching the Nikon colors, but I don't like a few of the Nikon colors. Some colors have too much Red, but Red is too Orange.
I have selected a number of images that have colors I want to change. I selected the Camera Neutral (v0) and Camera Portrait (v0) and using the latest DNG Profile Editor I select the 18 colors from the Color Checker Chart. I then use the images that have the colors I want to change and determine which of the 18 points I selected from the Color Checker are close. I then edit those points - only 6 points. I only need to change the Hue by 5 units or less. I don't change any of the other selected points of the Color Checker, but feel that by selecting them I locked in the exisiting colors. Hope this is a good aproach.
I wish Nikon would do something equivalent to the DNG Profile Editor for their Picture Control profiles so they could be edited and loaded into the camera.

Creative use of CC calibraton in the DNG Profile Editor

The DNG Profile Editor can be used to create profiles that mimic film looks.
I think right now it is manual trial & error process involving changes in hue, saturation and lightness, but it could be theoretically achieved with Color Checker calibration working in reversed order.
- Photograph the CC using your favorite film
- If B&W, develop in your favorite developer
- Scan the film
- Use the scan in the DNG Profile Editor as target values
The current DNG Profile Editor obviously does not allow that, it would require adding a new tab and clone the CC calibration feature and alter it to use the photographed values as target values as opposed to internal values.
I don't know if it would be worth the effort, but I thing the idea is worth of sharing.
By the way, unless I'm doing something wrong, the saturation slides don't seem to go 0%, so creation of B&W profiles is not possible.

Good idea. Yes, I've posted an example on my Flickr.
I chose a picture with good reds and yellows. There are four images in the set:
1. The original, untouched image. This is using the new Adobe Standard beta profile, brought into Lightroom with all default settings, including linear tone curve, no exposure or color adjustments, white balance "as shot", etc. For reference.
2. The image with my test profile applied, but no further adjustment.
3. My original attempt at the image, using the "old fashioned" pre-DNG-profiles raw processing method, for reference. The yellows are orangeish, which isn't that objectionable but also isn't accurate. The reds are weaker than I would like.
4. The "final" image, with my test profile plus additional tweaks -- white balance, tone curve for contrast, crushing out the blacks a bit more, etc. Two or three minutes of total processing, versus quite a bit more for the previous attempt with no "special" profile. The reds and yellows are perfect.
The Flickr set:
http://flickr.com/photos/100mph/sets/72157606547890574/
This was just a first, pretty quick attempt at playing with the DNG Profile Editor. I'm sure it can be tweaked more and even more can be accomplished.
[Edit: note: I changed the "upload date" on the test images so they wouldn't stay at the top of my Flickr page. Ignore the 2007 date, it doesn't mean anything.]

Camera Calibration in ACR & DNG Profile Editor

I am having the hardest time figuring out how to use the camera profiles generated with DNG Profile Editor in Camera Raw.
I am using Photoshop CS4 in Windows 7. I have generated the .dcp file with DNG Profile Editor and saved it in the folder: Program Files/Adobe/Photoshop CS4/Presets/Camera Profiles.
This is about as far as I've gotten. I have not been able use this profile in ACR under the Camera Calibration Tab. I have been lead to believe that is would show up automatically. I have not found any video tutorials related to ACR and installing Camera Profiles. They all seem to relate to Lightroom.
Any help would be greatly appreciated.

If you would like to look or copy profiles manually (for example you have received a profile made by someone else; for Windows7 you should be able to see where the Profiles are stored by searching for *.dcp (meaning any file with the extension .dcp)
That will show you where the Adobe supplied profiles are located. You can copy your custom profiles to the sub-folder of your camera type in the Camera folder.The other folder you see is where the Adobe Standard profiles live.
If you cannot see the programdata folder (and that is the case by default) you can make all hidden files visible:
(this from Windows Help, just search for show hidden files)
Computer>Organize>Folder and search options>View. In Advanced settings check the radio button Show hidden files, folders, and drives and then OK
Now you should see the programdata folder visible under your system (C:) folder
I hope that helps.

Camera Profiles and DNG Profile Editor beta 2 now available

Hi everyone,
Beta 2 of the camera profiles and DNG Profile Editor are now available. Please visit here and enjoy:
http://labs.adobe.com/wiki/index.php/DNG_Profiles
I hope to have more detailed release notes/changes for you soon. You are welcome to ask questions, but please note that it may take a while for me to respond.
Eric

Eric,
I followed very carefully your instructions for installing the new beta2 profiles and deleting the beta1 profiles, but have the same problems as many others. I'd like to provide a bit more information. I'm running Windows Vista Home Premium and have installed Photoshop CS4, updated with ACR5.1 and Lightroom 2.1 final release. As others have described, the default for all of my images was set to one of the Camera profiles (Canon faithful beta1), but now the profile name in Lightroom is blank. I tried looking at the other profiles and it does indeed appear that the beta2 profile is being used, but if I then reset the image it now shows ACR4.4, whereas the image had been imported with the camera profile as default. Also, if I open an image in ACR5.1 that was specified to use the same camera profile, it now shows ACR4.4 and it is not using the beta2 profile of what I had been using, I can see this by selecting the other profiles. Going back to Lightoom, I guess I could select all my images and select the Canon faithful beta2 profile, but then the mark shows up bottom right of the image showing that they have all been edited/modified, is there anyway to get all my images using the profile I was using but the beta2 version, without this happening and how about new imports?
Thanks, David.

Converting LUTs to Camera Profiles in the DNG Profile Editor

Hi,
I've just started using the DNG Profile Editor, and can't seem to get the process right.
I have some film LUTs that I'd like to convert to camera profiles for my 5D Mk II.
Here's how I'm trying to do it, maybe someone can help me figure out what I'm doing wrong.
This is what I tried first:
1. Take a Color Chart into Photoshop, apply the LUT via Color Lookup adjustment layer.
2. Save out as 16bit TIFF
3. Open as Camera Raw, then save out as DNG
4. Open the adjusted color chart into DNG Profile Editor, run it through the color chart section to create a recipe of color adjustments.
5. Export out as Camera Profile
But when I open up a 5D image in Lightroom, the profile doesn't show up in the list, so I realised maybe it needs to be saved specifically as a 5D profile, but I can't figure out how.
If I:
1. Do steps 1-4 as above
2. Open a 5D DNG file so that I can set a 5D profile as the base profile
3. Load the recipe
The color adjustments appear on the color wheel, but nothing happens to the 5D image, no colour change at all.
Exporting it (which does say 'Export as 5D profile') does then give me a profile that shows up in Lightroom, but it doesn't do anything to the image...
What's the correct way of doing this?
Thanks!
S

I don’t know claim to know anything about the internals of DNG Camera Profiles, but I’m pretty sure you cannot take a RGB-file (TIF/JPG) DNG and make a raw-file DNG Profile for use with your camera raws, which sounds like what you’re trying to do.
Despite looking like it might work in DNGPE, starting with an RGB-file recipe (rather than a RAW-file recipe) will only lock the specific colors on the color wheel, rather than create a raw-capable camera profile.

DNG Profile Editor won't open DNG from Panasonic LX3

I need help. I've just added a new camera (Panasonic DMC LX3) and I want to create custom camera profiles for use in Lightroom. I have done this with all my cameras before with no problems. The raw files open fine in Lightroom (2.6) and CS-4 Camera Raw (5.6.0.148). First I exported to DNG from Lightroom then tried to open the file in DNG Profile Editor. I received the following error message:
"DNG Profile Editor could not open the selected image. Note that the selected image must be a valid DNG colr image". I tried the usual closing and re-launching the application, restarting the computer, etc. all to no avail. I then downloaded the latest stand alone DNG converter (5.6) and performed a fresh conversion with that. Still no luck. The DNG's all open fine in Lightroom and CS-4. Any suggestions? These profiles have become an important part of my workflow.
Mac Pro 2X 2.8 Quad Xenon, 10GB ram, 4TB HDD, OS-X 10.5.8

DNG Profile Editor 1.0.0.39 Beta 2

Yes, I used the stand alone converter as well as lightroom. I did find a solution on another post. I changed the dng compatibility in the drop down menu to "Camera Raw 4.6 and later" (it was set to " Camera Raw 5.4 and later") and it worked fine. This worked with both the stand alone DNG converter and exporting as DNG from Lightroom. It seems that the DNG profile editor hasn't been updated since the 2008 beta so It doesn't recognize the newer spec DNG. Thank you for your assistance, I was starting to panic...

Do DNG HueSatDeltas correspond to DNG profile editor points?

I understand that the HueSatDeltas table in a DNG profile has 90 hue divisions & 25 saturation divisions (2250 total, excluding the value positions)... and these in turn record the hue shifts and saturation scales from these points.
Does anyone know if the dropper points on the color wheel in the DNG profile editor correspond directly to these 90 x 25 positions... Or are they simply arbitrary positions in the editor from which the resultant surrounding hue shifts and saturation scales of the adjacent points in the 2250 DNG profile positions are interpolated/calculated?
I had hoped that I could find the values corresponding with the 24 patches on a color checker and determine the hue shift/saturation scale recorded from these by reading the DNG profile... Or will that simply not work?
Thanks!

I am also uncomfortable with the 1.0.0.46 release with a D800.
Using Lightroom 4.2 I looked at the color checker chart that I used to generate my profiles using the DNG Profile editor. The blue change with this release was very significant.
Hovering over the blue panel of the chart after changing just the camera profile I got the following general readings:
Adobe Std.         R0    G22 B60
Beta 3                   R4    G18 B59.5
Beta .46                R17 G22 B59
Without an explanation, such a deviation from Adobe Standard is disconcerting as my base profile in the DNG Profile editor, both releases, was color checker.

DNG Profile Editor: Can't create profile from JPG file

Guys, could you tell me why DNG Profile Editor fails to create color table using 4 colored circles ? It says "Unable to check white balance using gray patches. Please use the four color circles to identify the four corner patches of the chart and try again" even though I places four circles properly (it works with DNG files shot with my Nikon D700).
I created this DNG file from JPG file by opening it in Camera Raw plugin and saving as DNG file. Original JPG was shot on camera of Samsun Galaxy S phone. I know I'm crazy but I want to have color profile for it All patches are properly exposed after slight correction of Exposure slider in Camera Raw.
I'm using latest beta3 build
Here is link to DNG and JPG file I'm trying to use
http://www.box.net/shared/4v2rzlzjfp
Thanks!

If you convert your JPG to a DNG can you change the profile to the one you computed from the other JPG you converted to a DNG?
Profiles are not for JPGs. Profiles are for RAW files that ACR supports. You can't (easily/ever) get a RAW file from your Galaxy S and Adobe doesn’t' support that RAW format even if you could.
To see if your profiling is working, you can used the ColorCheck module from a trial version of Imatest that you download from www.imatest.com and look at the color-error.
You can also try the Read_Color_CC24.jsx script from Rags-Gardner:

Questions about DNG Profile Editor recipe code

I have been playing around with DNG Profile Editor. With a text editor I made the following recipe:
I have some questions:
1. Right now I have my control points at 60 saturation. Will using two points for each color (say 70 and 40) make my changes more consistent across darker and lighter shades of the specific color?
2. Does DNG Profile editor respect HueLow and HueHigh, are they just placeholder numbers, or are they ignored if two points are close to each other?
3. What does FeatherAdjust do? I'm guessing it controls the rate of drop off of the corrections. Is the value respected by DNG Profile editor when it creates a profile?
Thanks for your time and attention, -Bruce.

1. For now DNG-only. Here's why:
http://labs.adobe.com/wiki/index.php/DNG_Profiles_FAQ#PEOnlyDNG
http://labs.adobe.com/wiki/index.php/DNG_Profiles_FAQ#WhyNameDNGPE
http://labs.adobe.com/wiki/index.php/DNG_Profiles_FAQ#WhyPESeparate
2. Standalone for now. See above links for why.
3. Use the 'Preview Color Changes' option in the Options menu.
4. You can use 'Apply Raw Adjustments' in the Options menu to see your raw adjustments. This is __not__ recommended for building a general-purpose profile because you are then optimizing a profile with specific image adjustments in mind, rather than building a profile based more on the inherent camera characteristics.
5. True, that is a limitation of this implementation.
6. I am not sure what you mean. The Chart Wizard automatically optimizes the color patches in a test shot based on reference values for many physical charts, which is more practically useful than the numbers printed on the reference card that comes with the chart.
7. Make sure you avoid color casts in the bottom row. The PE is picky about making sure your gray patches are relatively neutral. It is an attempt to help you get a better profile.
8. Use 'Show Affected Colors' from the Options menu.
You may wish to read this page carefully and thoroughly:
documentation
It is the reference online documentation for the DNG Profile Editor and a few of the things you wish to do, such as preview all color changes, apply raw adjustments, and visualize the extent of each color adjustment, are all documented there.

What kind of DNG file for DNG profile editor ?

Can somebody help me??? I have a problem to use DNG profile:
I am user of Fujifilm S5Pro, which has RAF file (=raw). The ACR (start from version 3...) and DNG understand my RAF files very well. But DNG profile editor dose not want to open it, even if Adobe DNG Converter 4.5 converts it to DNG file. My workflow is:
Launch Adobe DNG Converter.exe, => convert RAF to DNG (tryed different settings);
Launch DNG profile editor, => trying to open DNG file => have error???
May be I'm doing in a wrong way? Please advise me.

I tried to do the same on other PC with Vista (fully English). Also update DNG converter up to 4.6. And no success... :-(.
Every time I have the same error: "DNG Profile Editor could not open the selected image. Note that the selected image must be a valid DNG color image."
I could not understand... where is a bug.
Moreover, I took NEF from Nikon D80 and CR2 from Canon 20D and converted them to DNGs by converter 4.6. DNG Profile Editor did not want to open them on both Windows Vista and XP, and made the same error.
Do I really do wrong things? I'm completely lost
Thanks in advance,
Slava

About to use DNG Profile editor

I've had my Colorchecker for a few weeks, and I finally have time to set up my profiles for LR 3.4. In reading the DNG Profile editor tutorial page (http://labs.adobe.com/wiki/index.php/DNG_Profiles:Editor), I have a few questions:
1) If I use Tutorial 5, I am guessing I will have to create a profile for each lighting/WB condition, i.e., one for Tungsten, one for Fluorescent, one for sunny, one for overcast, one for flash, etc... Is that correct? Is there an advantage to doing this vs. going for the dual-illuminant approach explained in Tutorial 6?
2) In Tutorial 6, for the dual illuminant profiles, it states that one of the reference shots should be taken at 6500K. I'm not quite sure how to achieve this, since daylight and flash, to semi-constant WB sources I can easily achieve, are around 5000-5600K.
3) Should I (in LR) White-balance the Colorchecker reference shots, then convert to DNG, prior to bringing the DNG file into DNG Profile editor? Or is it preferable to WB as explained in Tutorial 1, step 3?
4) Finally, it's somewhat unclear how I bring the profiles into LR for use during the Import or Develop phases. Tutorial 1, step 9 mentions a "CameraProfiles directory" for ACR and LR, so I'm guessing I need to go digging through the Adobe folders to locate this directory and place/save my profiles there?

If you want a broad purpose DNG profile then yes, doing a dual illuminate profile is useful. Shoot a target under tungsten and under daylight and make the dual illuminate profile. There's no real reason you need to spawn off a bunch of other profiles for only slightly different light. The dual illuminate will handle cloudy or overcast just fine. If you also shoot with special lighting sources like fluorescent (which doesn't have a complete spectrum) or other non-standard lighting sources then do a profile for those special conditions. If you are creating a profile specifically for studio flash, you can get by doing only a single illuminate profile for the strobes...but in that case, the profile won't be as accurate if you also try to use it under tungsten–which would be the reason to do a dual illuminate profile.
As far as the D65 color temp, the closer you can get to it the better, but D55 should work fine. The key is to make sure it's evenly lit. The big difference between D65/D50/D55 is the relative amount of the blue light components-all three will be fairly close. Tungsten however has vastly less blue which can impact the sensor's spectral response–which is why the dual illuminate is suggested.
Once you do the CC shot, don't bother with tone/color corrections in ACR before converting to DNG. They won't have a material impact on the profile creation. The CC shot MUST be evenly lit and of an optimal exposure...
As far as where the profile goes, it depends on the system. Once you've created the profile, PE should default to the correct location, otherwise state your system and we can tell you where to put them.

Camera Profiles and DNG Profile Editor

I saw the lightroom 2.0 eseminar and the presenter mentioned Camera Profiles and the DNG Profile Editor. All I see is ACR4.4 and 4.3. The the FAQ page says I need ACR4.5 and I can't find it and haven't gotten any update notice. Should I just wait for an update or forget it?
Don

>I have CS4. Will this overwrite ACR 5.1 in CS4?
If you have CS4, you should update to ACR 5.2. If you install 4.6, you will break your CS4 install. Either just run the Adobe updater app, or go to http://www.adobe.com/support/downloads/new.jsp to download it. DNG converter is a separate download. Both camera RAW and NDG converter contain the final release version of the new profiles. DNG profile editor can still be downloaded from Adobe Labs: http://labs.adobe.com/wiki/index.php/DNG_Profiles. There is also a profiles download there that you don't need if you install DNG converter 5.2.

How to make dual illuminant profile in DNG profile editor?

I have just started working with the DNG Profile Editor. In another discussion I commented on the clarity of the instructions provided by the tutorial. I had no difficulty creating a single illuminant profile using the X-Rite color checker passport. But when it came to producing a dual illuminant profile, following the instructions exactly, I was stymied.
1. Open dng image of Color Checker photographed in 6500K illumination.
2. Open dng image of Color Checker photographed in 2850K illumination.
3. Select Chart tab in editor.
At this point one is instructed to "Click the 6500 K-lit ColorChecker image window to select it."
But the 2850K lit image (last loaded) has replaced the 6500K image window (at step 2) and I can find no way to reopen the 6500 K lit image window in order to proceed to the next step.
As a matter of interest, why do these instructions suggest setting the pop-up window in the Chart Pane to "6500K only" and then create color table with first image. Thereafter select second image, set pop-up window to "2850K only" and create color table. I seems to me that, having loaded two images (even if I can only see the second image loaded) one should choose "both color tables" and then create color table. In fact I have tried this and it does produce a profile, but I have no way of determining if it is a correct dual illuminant profile.
Please help.

Note that the "Both color tables" option always creates a single-illuminant profile. The "Both color tables" option means that the computed color corrections will be applied to both color tables (i.e., the color table for the first calibration illuminant, which is usually Standard Light A, and also the color table for the second calibration illuminant, which is usually D65).
After playing around with the Profile Editor for a while, and examining the results with dcpTool, I now understand (I hope) what Eric is saying. In his language a single-illuminant profile is one created from a single dng image using the "both color tables" option (without regard to the illuminant used to capture that image.) When one does this (using Adobe Standard as the base profile) an examination of the resulting profile with dcpTool shows the following:
Two illluminants are identified: 17 (Std A) and 21 (D65).
Color Matrix 1 & 2; Forward Matrix 1 & 2; Hue Sat Delta Tables 1 & 2.
Which certainly gives the impression of a dual illuminant profile to novices like myself. My guess is that the PE software itself applies a default assumption of these two illuminants, corrects the image for each illuminant and constructs two color tables, one for each illluminant. When used, the profile will interpolate between the two tables based on the white balance of the image being edited.
If this is indeed correct it makes me wonder in what way does such a profile differ from a dual illuminant profile created from two dng images, each captured under a different illuminant (2800K & 6500K) as described in Tutorial #6 of the PE instructions. These instructions contain the following description of such a dual illuminant profile: "The result is a single profile that performs well under a wide range of illuminants instead of a single fixed illuminant." Which really make me scratch my head. Should one conclude from this that a single illuminant profile (created using the "both color tables" option) will perform less well under a range of illuminants? Will it perform well only under a narrow range of illuminants centered around the illuminant used to capture the single image?
As a footnote, it is worth remarking that I (and perhaps others) have been confused by examining profiles created by the XRite software when using only a single dng image. Examining such a profile with dcpTool one sees the following structure:
One illuminant only #23 (D50)
A single Color Matrix table.
A single Hue Sat Delta Table.
Thus one comes to expect this structure in a single illuminant profile.
I would be very happy to see Eric's comments..
