DNG Profile Edito ERROR on selecting color chart

Hi,
when I select a photo of the color checker card (DNG from Sinar e65 back) and want to create the color tables I get an error message
Runtime Error(PE_ASSERT)
A fatal runtime error....
Description: invalid hue
Source filename: pe_recipe.cpp
Source line: 2734
The Profile Editor quits after that.
Any idea ?
Bug ?

Hi Eric,
a wonder, mirical or what ?
Now it works.
I have created a simple profile without the color checker card. Now when I load the DNG the Profile Editor uses that profile and I have no problem anymore working witht he photo of the color checker card.
I assume, as the "Sinar Hy6 65" is unknown to Adobe by now that you must have known profile as base to be able to use the automated tools for colors.
May be a matter for the doucmentation.

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:

DNG Profile Editor "base profile" question.

I'm profiling a Canon 5D3 with both the Adobe DNG Profile Editor and the Xrite ColorChecker software. It's been about 3 years since I last profiled a camera, so I'm re-doing the learning curve. My question now is how and why the DNG Profile editor depends on a "base profile?" Specifically, why does the DNG PE Chart Wizard generate different results depending on what base profile is used.
I see in the documentation that "all color adjustments made in the DNG Profile Editor are defined relative to a base profile." I understand that logic when making a custom profile via manual tweaks. You have to have a starting point. But I don't understand that logic when using the Chart Wizard. I expected the Chart Wizard to arrive at the same pre-defined target point regardless of the starting point. It does not seem to do that.
I discovered the difference by using an apparently bad workflow. I shot my colorchecker chart, converted the CR2 to DNG and brought it into Photoshop via ACR to inspect. That stored "Adobe Standard" as the base profile in the DNG.
Then I fed this DNG to the DNG PE Chart Wizard and generated a profile. I opened the image in ACR and applied "My Profile", which became the base profile in the DNG file. I thought I did something wrong, so I ran the same DNG through the Chart Wizard again and generated "My Second Profile." That version looked very strange, so I did it again and made "My Third Profile."
Now I have three profiles. My First Profile was made from Adobe Standard base. My Second Profile was made from My First Profile base. My Third Profile was made from My Second Profile base. Each iteration becomes more strange (bad), so this is clearly not the proper workflow. But what is? What base profile should be selected for Chart Wizard and why does it matter?
Being curious, I did the same exercise using the Xrite ColorChecker software. That software generates the same result, regardless of what base profile is stored in the DNG files. I'm not sure I like the results, but at least they are consistent.

DNG Profile Editor lets you define color edits (in the first tab) using a set of color control points. These control points in turn define a color lookup table used to perform the color correction when processing a (raw) image.
When you use a Base Profile, the resulting color table in the final profile is a combination of the base profile's color table, plus the color table defined by any edits that you've added in the first tab (using the Chart Wizard counts as adding edits to that first tab).
The reason you can get different and less smooth results if you apply the Chart Wizard iteratively is because you are applying lookup table after lookup table. The current color table-building method used by DNG PE has some limitations regarding smoothness of color profiles if two color control points are placed too closely (this can happen with the Chart Wizard, or if you specify two points manually that are close to each other). These problems can become more noticeable if you apply the DNG PE iteratively.

Adobe DNG Profile Editor

Has there been any update to this beyond that in 2008 found on Adobe Labs? (I want to try using it to calibrate ACR for my camera with a shot of a MacBeth Color Chart.)
To be more precise about this, I currently use ACR Calibrator to calibrate ACR for my Canon 1Ds II. I now see there is beta 3 of Adobe DNG Profile Editor but note that it utilises a small subset of the GMB Digital Colorchecker SG target chart.
ACR Calibrator seems to produce quite different results from Adobe DNG Profile Editor. I have followed the steps below when using the latter.
Download DNG Profile Editor and drag to Applications
Launch Photoshop and open the raw file of your macbeth target.
In camera raw, place all settings to zero, curve to linear and turn off any sharpening etc. Click Save Image, choose dng as the file format and save it.
Launch DNG Profile Editor.
File / Open DNG File and choose the dng file you saved previously.
Select the chart tab in DNG Profile Editor.
Move the colored circles to the center of the matching colored corner square in your raw file
Click Create Color Table.
Choose File/Export <Camera> profile... Give it a name and save.
Exit DNG Profile Editor.
Re-launch photoshop and open a raw file. In Camera Raw, on the calibration tab, you should now see the profile you just saved.

I don't know of any other references or CC Passport numbers other than what Google can come up with. Babelcolor has some standard-deviation of spectrum numbers for a sampling of 20 charts done in 2006 and also some worst-color vs average-color visual comparisons to get an idea of how variable charts or at least their measurements can be. Somewhere it says the me4asurements were done of the standard and also the minichart, mixed together, I assume. I don't know if there is a list of the raw data or not.
To understand the source of the variation you really need to see multiple measurements with the same instrument, with different instruments, and of different charts from different manufacturing runs and different ages and measured in different temperatures and humidities, otherwise it's not easy to say whether the variations we're seeing between the CC standard and the CC passport in the article are within the normal variations or not or if they represent a significant difference not explained by normal variations.
Yes, I know the Babelcolor data and I have already included them in the study.
Obviously I do not have the opportunity to have the information to get an overview of the real things, but by analyzing various measurements I saw that Myers had to be the closest to official data of the CC Passport and instead is the more distant. Hence my doubts about the measurement.
Thanks anyway.

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!

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.

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 profiles, Calibration tab vs. HLS

Cross post (asked on the DNG forum but there isn’t much activity so forgive me)
X-Rite and Adobe have provisions for creating custom DNG profiles. DataColor just announced a product that appears to operate like these two but instead of making DNG profiles (or as we had in the old days, altering the Calibration Tab), updates the HSL controls. My understanding is that DNG profiles and the Calibration tab operate in a different order of the processing, prior to all the sliders above them. My understanding is there are benefits for doing this but I’d like to know more about this. The question is, what are the practical implications of “calibrating” via a target that affects HSL sliders instead of producing a DNG profile, or at the very least, altering the calibration sliders? Eric you out there bud?

I'm not Eric (not sure he would want to respond to this question) but I'll take a stab...first off, let me state that I haven't personally tested either the SyderCHECKR PRO color target or the software. I've only watched the video and read the user manual. But I do have some issues regarding usability and the "practical implications" of using the HSL Sliders vs a DNG profile.
There is one major implication–the SpyderCheckr produces a preset using the HSL adjustments rather than a DNG profile. I have no understanding (and haven't heard the rational) why Datacolor chose a Lightroom or Camera Raw preset instead of a DNG profile. But the first problem with creating "presets" is Lightroom and Camera Raw don't share "presets". So, unlike a DNG profile which will work in both Lightroom AND Camera Raw, the Spyder solution is application specific. The other major issue is that presets are not easily transportable compared to DNG profiles which actually get imbedded in a raw file. I have no reason to suspect that the HSL adjustments of Lightroom and Camera Raw CAN'T handle the color corrections needed for calibration, but the fact that the calibration depends on a "presets" limits its usefulness.
What is also not mentioned in the videos nor the manual is what the user is supposed to do regarding the starting DNG profile. Does Datacolor suggest using Adobe Standard or some other DNG profile? I ask because the HSL calibration applied as a preset depends upon the DNG profile used to create the color sample file and adding a calibration on top of an existing DNG profile seems to complicate the whole calibration process. When using DNG profiles, it's pretty straightforward what the DNG profile creation is actually doing. Adding an HSL adjustment on top of an existing DNG profile adds complexity to the process and reduces the portability of the camera calibration.
The documentation seems to imply that both DNG Profile Editor and X-Rite's Passport solution somehow limits the end user's ability to make further adjustments. I think this is false...while you can't currently edit the resulting Passport generated DNG profile in X-Rite's software, you can indeed edit the resulting Passport generated DNG profile in Adobe's free DNG Profile Editor. You can edit the preset that SpyderCheckr creates in either Lightroom or Camera Raw, but you are editing an absolute preset that applies HSL adjustments requiring the saving out of a new subset of HSL adjustments-and again presets are not interchangeable between Lightroom and Camera Raw. I see this as a very limiting factor.
In principal, I encourage the development of more and better solutions for both Lightroom and Camera Raw. Whether or not the HSL calibration approach is superior to the DNG profile calibration approach, I really wonder whether or not HSL is a better solution than the DNG profile approach. It seems to me that Adobe (and Thomas Knoll and Eric Chan) have spent a lot of time and effort to develop an open solution to camera calibration that the SpyderCHECKR approach is ignoring. Personally, I would have encouraged the option to create either a DNG profile _OR_ an HSL calibration preset. I think it's a mistake to ignore the DNG profile approach.

Q for Eric: DNG Profiling - Color Matching

This question is primarily directed towards Eric in reference to an older tutorial he published on the web:
http://people.csail.mit.edu/ericchan/dp/acr-color-match/
I'm trying to work with the DNG Profile Editor to make a 5D profile that matches Capture One's 5D profile. In the past, I used a similar approach to the old way of profiling in ACR/LR, basically like the old tutorial I referenced above.
With the new DNG PE, how can I perform similar functions with the Tone Curve and Color Table since I can't place sampler points in the DNG image of the color chart? Also, the RGB values in the PE are vastly different (lower) from what I see in Photoshop. Are we supposed to eyeball the adjustments hoping they're in the same neighborhood? Is there a more precise way of doing this?

Hi Terence, there's not a numerical way of doing this in the PE. For now you basically have to try to get the match visually.

Error 0xBFF60492 on IMAQ USB snap.vi RT Video not support displaying selected color depth

Attempting to snap a picture with NI-IMAQ for USB in LabVIEW 8.0 using the following procedure.
1)I get the first enumerated camera, 2) open a session, with returned

The image passed is not valid.
Possible Reasons(s):
IMAQ Vision: (Hex 0xBFF60492) RT Video Out does not support displaying the supplied image type at the selected color depth.
I give the snap.vi an Image in from rightclick->Create->Control

Provisioning Profiles Generation gives "Unknown Error" after Selecting Members

Well, I can no longer generate provisioning profiles because it gives an unknown error after selecting members and clicking continue. Any workarounds?

They mentioned when I called that the (-18) error is a network error because of their activation servers being down at this time. They said the activation servers are used to authenticate restores through iTunes for the iPhone. It should be back up tonight or tomorrow sometime according to support.
So if its not back up by tomorrow I will call again. Thanks for the help.

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

Adobe DNG profile editor bug w/ GH2 files where aspect ratio is not 4:3

Hi,
posting here as Adobe DNG subforum is essentially dead
Panasonic GH2, select aspect ratio 3:2, get .RW2 raw file, convert it to .DNG using Adobe DNG converter (6.4.0.121 beta), try to open w/ Adobe DNG profile editor (1.0.0.39 beta 2) -> error message "DNG Profile Editor could not open the selected image. Note that the selected image must be a valid DNG color image".
XRite software has no issues to process the same .DNG file (converted from the original .RW2 w/ 3:2 aspect ratio).

Eric - just make it easier for you to reproduce the bug - here is the original .RW2 file (certainly ignore the quality of colorchecker shot in terms of how the target is lit, etc - it was not to make a profile actually - it was to illustrate the bug in question) = http://www.box.net/shared/f419prmuo2 ... and I am uploading the converted .DNG file too just in case = http://www.box.net/shared/gy5o9zzi57

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.

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.

2. HYPERLINK "/people/MadManChan2000"MadManChan2000,
Oct 21, 2013 9:09 AM in reply to blumesan
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..
