Documentation for DNG Profile Editor??

Hi. I am looking for the tutorial and documentation on Adobe DNG Profile Editor (v 1.0.0.39 beta 2). I assume this is the latest release, but if not, I would appreciate a link to the latest. I tried downloading documentation and tutorial from the following link, but the site never comes up.
http://labs.adobe.com/wiki/index.php/DNG_Profiles
I'd like to build some profiles for my 5DmkII and studio lighting situations, specifically for portrait / skin tone type work. Suggestions welcome.
Thanks,
Lou Dina

In the past I did some research in these fields and I want to share the fruit of that work (but English language is a problem).
> There can be Variations Among cameras.
I have analyzed two sets of cameras, two Canon 40D and two 400D illuminated by Solux Daylight 4700K bulbs.
The first test was done with a 400mm. Unfortunately, very little movement of the lens at f/5.6 (a mistake) has darkened the upper rows of ColorChecker and I had to correct them with the brush of ACR Exposure (the worst intervention reaches 0.17). After this intervention the cameras differ by an average error of delta E 2000 0.30 and a maximum of 0.75.
Link: http://www.boscarol.com/forum/viewtopic.php?f=58&t=321
The second test was done with a Canon 400D and a Canon Rebel XTi. In theory, the same model but for different markets.
Here the things were particularly interesting because:
- the cameras could be build from different processes due to different market areas
- the cameras were put on the market in 2006, and were produced with the technology of almost five years ago
- the cameras belonged to the entry level market segment, the techniques of production could be consistent with this low target
All these factors could lead really to differences in behavior. The results were an average error of 0.65 and a maximum of 1.26.
Link: http://www.gialandra.it/blog/files/343e438a6021337b5fdffb2cfbe0f08b-0.html
And probably if these tests had been made in laboratory the differences were even smaller.
I concluded that the differences in the behavior are all to prove.
On the Internet I found nothing of scientific.
> There are subtle Also Variations Among Conditions lighting, as well as chart shooting conditions (Exactly how the light is falling on the chart, the angle at Which you photograph the chart, etc.)..
These are the most important points. If the chart shooting conditions are a bit easier to control with geometry, get a light with a spectral power distribution right it is very difficult (and I suspect that even Adobe has not a decent D65 simulator). To obtain a light close to illuminant D50 I use 4700K Daylight Solux bulbs without glass diffuser. In front to the lamps I mounted a shape ring protection with a hole less than two centimeter (to avoid protection I have tried the black back version of the Solux bulbs but they do not have the correct spectral power distribution). Bulbs are powered by an adjustable power supply. Using the spectrometer as a feedback I can reach a CRI of 97.
It seems to me that even the not winter sunlight when the atmosphere is really clear is close to the D50, but I've never had a chance to measure it. In this condition the problems of non-uniform illumination do not exist, but be careful with the camera and target angles because the light is even more violent, the target should be perfectly at 45 degrees and the sensor should be parallel to the target.
Finally to have a more homogeneous illumination and all other problems I use only the mini format of the ColorChecker.
> There Are Also Among Variations lenses (eg, spectral transmission of Canon 50 f/1.4 is Not the same as Canon 180 f/3.5 macro, But They Are close).
I have studied the effect of five very different lenses in type, brand, cost, etc.. The spectral transmittance of the lens was so different to cause a shift of the white balance of 450K. On films this would lead to very different results, on digital system instead the human visual system is not able to appreciate differencies (worst deltaE 2000 is 1)

For my studies and my experience at this moment I think the best way to find the faithfull to the scene with a safe semi-universal profile is using the calibration sliders in D50 condition. From the linked experience below this gives faithfull from tungsten light (2600K) to above 10000K, of course this last only in daylight.
Link: http://www.photoactivity.com/Pagine/Articoli/023%20Calibratori%20al%20sole/Calibratori%20a l%20sole_en.asp
In this context I still use the script of Tindemans but it is time (many years now) that Adobe produces his matrices tweaker (XRite Passport stresses the matrices as far as possible before creating some sort of table)
I hope that I'm not boring

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

DNG profile editor : where can we find a link for downloading an updated version (for Mac OS 10.9)

The links I found here (http://www.adobe.com/downloads/updates.html) are both for Windows, althought one is named "MacIntosh".
The beta version seems to have problems on Mac OS 10.9 (it is impossible to quit the application).

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.

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.

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.

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.

DNG profile editor

A couple of questions about DNG Profile Editor:
1-I know Lab values on my ColorChecker (measured with an EyeOne 2° D50). I shooted it with a Nikon D80 and I want to tweak one of the new Camera Raw profiles to match those values or to go closer. I see that changing the base profile (popup menu in Color Tables Pane) the image appearence changes a lot but the Lab numbers readout doesn't. I followed the tutorial on the Adobe site but I can't figure out how to make the camera calibration without having a numeric value, before and after, to look at. The tutorial tells that you may 'adjust the selected color via the Hue, Saturation and Lightness slider and you will see the preview in real-time'. That's true but does it means that is a sort of 'visual calibration'? Is there a way to tweak colors by the Lab numbers in order to have the best match from original Lab values in input (on the target) and Lab values in output (in a ProPhoto rendered image)?
2- When I create a Color Table from my ColorChecker it appears that in the Color Tables colors are already (and automatically) changed. Does it work like the ACR Calibration Scripts that way? And is it possible to change the reference Lab values (ColorCheckers are different in color values) as it was with a simple ACR script's editing?

Eric,
Before starting, I want to say that I had cataract surgery last month. The vision improvement was almost instantaneous and dramatic. I can now state that color differences in individuals can be much greater than expected. It is hard to express how big the difference is in my own vision, let alone between two other individuals. Any color assessment tools must accommodate numeric as well as visual comparisons. That said, the healing process has also affected how much time I can spend comfortably in front of my screen. I hope my comments will be taken constructively.
As others have commented, I also feel that the CC24 Lab target values being used should be documented. Published values from Gretag, Lindbloom, Babbage, and others disagree. Without the target numbers it is difficult to determine accurately the calibration result.
My first attempt seemed to go smoothly, but when I verified the results with ReadColors.jsx (my script) the numbers degraded slightly. I was using the Gretag target values, so these may not be what Adobe is using. Also, I had already calibrated ACR for my D3. The doc seemed to imply that the ACR tabs would all default to zero and that was what displayed in the Color Matrices panel. But that was not what showed in the ACR panel. So I tried again, setting all ACR sliders to zero. This calibration attempt was a disaster, numerically and visually. Now I am confused. What is the relationship between these and what are the recommended user actions? In each case, I exported the DNG profile and selected it subsequently in ACR to re-open the image.
Next, I played with the Color Tables panel. I set a watchpoint on the blue patch. As long as I hold the eyedropper over the blue patch the Lab (and other numbers) track. But as soon as I move the mouse to the sliders, the numbers disappear. If I move the hue and saturation sliders the image and the patch sample both change. And, yes a little arrow shows in the color wheel. But after moving the eyedropper back, none of the numbers have changed. The lightness slider is even more bizarre. Obviously no arrow (z-axis) but the image brightens and darkens (OK), without any corresponding change in the patch sample (watchpoint) on the right (not OK). And again, no change in the numbers at all. It would be very helpful if the target values were shown here and if the currently selected watchpoint that would track the numeric changes. It would also be nice if the watchpoint could show the target color as well as the initial and changed image patch colors.
I dont understand the purpose of the Tone Curves. I understand gamma and Adobe linear, but these do not correlate to the ACR tone curves. And again the image changes but the numbers do not. Since we cannot set watchpoints in the neutral patches it is very difficult to assess any changes the user might make.
Next, I used the Chart panel to Create Color Table. When I return to the Color Tables panel, there are the 18 color (no neutral) watchpoints. I can see that blue has changed in the watch point and the arrow in the color wheel. But the numbers are still the same as before. Scrolling through the watch points I can also see that the hue and saturation sliders have changed. But the lightness slider did not change in any of the color patches. I anticipated that this would be the major improvement over the ACR sliders. Is this just not in the calibration algorithms yet?
This is a good start, but until I know what the target values are and what I should be doing about the existing ACR slider settings, I am at a stopping point.
Cheers, Rags :-)

DNG Profile Editor - questions about

0) Thank to Eric Chan for your work on this. Until now I used the Camera Calibration process through Photoshop and Camera Calibration table. But I see this as a big progress.
1) Will it stay only DNG editor or it will be also for raw pictures without a necessity to convert them to dng?
2) Will it be only stand alone aplication or as well a part of the LR?
3) Now I can switched off and on one color change (by the left mark in the Color List Box). Could it be possible to switch off and on the whole Color List Box to see all done changes?
4) I have red your comment that this tool doesn't work with lightness, only hue and saturation. But if I want to work on a specific picture (i.e. a man wearing a red sweater), it will be fine to have it in the brightness close to an end picture. Will it be possible to open a picture not only with WB, but also with exposure, blacks and other basic development setting?
5) Under the eye drop tool, I can see numbers of "initial" or "starting" color. But I can't see the numbers of changed color. It would be fine if I know the new numbers to see how close I am to them. It would be fine if the number over the color List Box will be also for starting color and also for end colors.
And one little proposal: if the color will not change, show in Color List Box only the starting (left) half of a color. Than I can simply see that I didn't set a new color or the color stay exactly the same (it is only a question if exactly the same or very close to the same).
6) It could be, that I will not use the exact color checker table for what you did process on the tab Chart. But many of color checker are delivered with exact numbers and picture on a cd, so it will be fine if I could open this "master" picture of a checker producer in a right panel under the Color List Box and simply take from it the end colors. First go to the main picture on left, choose the "initial color" and then simply go to this "master" picture in right and take the "end color". What do you think about this?
7) If I work on the tab Chart, I get the error window "not neutral gray patches, row 4 culumn 1". But if I move the circle to row 4 culumn 2 it works fine. Is there any difference or problem?
8) And last: how far is acting the shift of color. It will not work only for the one color but close surroundings will be also efeccted. How smal or large is the surroundings? E.g. if we take 360 degres for hue.

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:

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.

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.

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.

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?

>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.
