Looking inside of DNG Camera Profiles and editing them

For those interested in the insides of DNG Camera profiles, and how to edit them, I've written dcpTool.
dcpTool is a compiler/decompiler for DNG camera profiles (.dcp files). dcpTool can decompile binary format DCP files into an XML format for editing with a text editor or whatever, and then compile the XML format file back into a binary DCP file, as well as extract embedded profiles from DNG files. It runs on Windows and OS X command lines, and is based on V1.2 of the DNG SDK.
See here: http://dcptool.sourceforge.net/
Health warning: dcpTool is a command line utility - if you're not comfortable with command line stuff, dcpTool probably won't be of any interest to you.

Very cool, thanks for the info.

How do I find camera profiles and load them into Camera Raw?

I did a clean install of Windows 7 and reloaded all my apps. Photoshop CS5 and Camera Raw used to show my Canon 60D & its lens, but now has no camera profiles. I found a way to lookup the camera/lens profile in Photoshop (Filter - Lens Correction), but not how to save it, so I have to do it every time I load PS. I can't even figure out how to get one into Camera RAW. Doesn't seem like this should be so hard. I must have figured it out when I first loaded CS5, but now I can't seem to get there. I figured a quick trip to Google would solve the problem, but no soap so far. Lots of advice on how to use profiles, but nothing (except invalid pages) saying how to get the darn things in there to begin with. Any help would be appreciated.

Did you install the camera raw 6.7 update?

You probably need to search, download and install the other photoshop cs5 updates as well, if you've just installed photoshop cs5.

DNG Camera Profile vs. White Balance?

I'm having trouble understanding DNG Camera Profiles and haven't found a good explanation online. I understand that each camera or camera/lens combination will have some variations, and I understand the white balance process. But I haven't grasped the idea that I can create a usable profile using one or two ColorChecker shots in conditions that aren't tightly controlled. For example, if I create a DNG Camera Profile using my tungsten lights, how does that help correct photos shot using different slightly warmer or cooler lights? How does the profile taken at an unknown color temperature help correct for another color temperature? And (more fundamentally) how is what the DNG Camera Profiles do different from a white balance adjustment? Feel free to just point me towards an existing explanation. I've read a lot about camera profiles, but I still don't quite get it. Thanks.

See this Luminance Landscape thread about dual illuminant profiles:
http://luminous-landscape.com/forum/index.php?showtopic=43733
If you scroll down to where I (tlooknbill) posted Color Checker chart samples, you'll see the visual differences.

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.

LR 4 and custom DNG camera profiles... they are not embedded?!

i have the colorchecker passport for some days.
my workflow:
import the .CR2 raw files from memorycard as DNG copy into lightroom.
create a DNG camera profile with the colorchecker passport (LR export -> xrite colorchecker).
then i choose the created camera profile and i set the whitebalance.
all working fine... as it should.
my problem is, i don´t want to have a hundred DNG profiles, i will sure create that much over the time, on my harddisk.
i think it´s messy and it´s also not very save to have the profiles only as separate files, in case you lose the profiles.
i thought the camera profile can be embedded INTO the DNG file.
i thought the camera profile is written into the DNG files when i write the metadata back into the files.. but it seems not.
it seems the DNG camera profile is only embedded into the DNG image file when i EXPORT the DNG file again with the LR export dialog.
for example:
i choose the camera profil "MY 5D MK2 PROFIL_1" for an image and then save the metadata back into the DNG image file.
then i delete the camera profile "MY 5D MK2 PROFIL_1" from harddisk.
the next time i open LR and select the same image ... the cameraprofile is reverted back to "adobe standard" and the profil i have created is gone.
when i EXPORT the image as DNG, then even after i have deleted the DNG cameraprofile "MY 5D MK2 PROFIL_1" from the hardisk.... the profil is still in the DNG image.
that´s what i want... but i have to export all files again as DNG files.
i would really like to get rid of this extra step.
i hope my english is good enough so you understand what my problem is.
can anyone share a light on this?
is this the only way to embedd the DNG camera profile or im doing something wrong?
intel i7 2600k, win7 64bit, 16 GB ram, LR 4 final.

possible.... but imho that can lead (at least in my case ) to problems.
in the case when you forget to update the DNG manually and delete the profiles (because you think they are already embeded via STRG+S).
or when you send them to someone without updating the DNG preview... i think that is unessesary complicating things without gaining a real benefit.. not?
afaik there is no filter option so you can create a smartfilter for images that need to be updated this way?

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.

DNG camera profile - which to trust, Adobe's or X-Rite's?

I found that dual-illuminant DNG camera profiles created with X-Rite's ColorChecker application and Adobe's DNG Profile Editor give different visual results (the profiles were produced using the same set of 6500K/2850K illuminated photos). I'm now in trouble which profile(s) to trust, I assume Adobe's is correct...

Me too. The purpose of the twisting is for more pleasing color. Cool dark greens, but warmer light greens; dark midnight blues, but warmer cyany light blues, deep dark reds, but warmer light reds...
Note: this exagerates what often happens in real life: shadows are cool, sunlit colors are warmer...
The linear profiles may be more accurate, but the twisted profiles may look better.
Obviously this is subjective, and may depend on the shot and the purpose for it...
My favorite profile is a customized version of Adobe Standard created with DNG Profile Editor - a little dimmer in the upper-midtones/lower-highlights, a little less cyany blues, a little cooler greens, and slightly warmer (less magenta-y) reds.

Help me understand matrix profiles (DNG camera profiles)

I'm guessing it's a fairly simple question, so please bear with me as I'm working my way round trying to understand the DNG format:
After the de-bayering step, are DNG camera profiles pure 3-channel mathematical curves? I know Adobe DNG editor allows for adjustments from the Color-checker patches & there's some hue sliders etc, but do these build into RGB curves, or is it some kind of additional mild LUT (or something else) applied over the top?
Thanks!

Camera profiles and Highlight Recovery: color shifts

I often see significant hue shifts and loss of saturation when using the Recovery slider in conjunction with the new dng camera profiles. I don't remember to ever have this 'problem' with legacy ACR profiles. In the sample below, you can see just that:
Sample: http://farm4.static.flickr.com/3224/2918603614_7a562db832_o.png
This becomes a bit of a problem, as recovering highlights now brings color shifts as a side-effect and you have to go fiddling with color controls.
Often, the new, 'shifted' colors are even more pleasing than the 'unshifted' (i.e. recovery set to zero), but this is a psychological and a workflow problem too. It is just not nice to know that controls are interdependent and have side-effects.
Is it a bug or a fact of life? What's so different about the old a new profiles, that cause this difference in recovery effect?
The DNG to play: http://www.yousendit.com/download/bVlBblFOR0Y3N0JFQlE9PQ

Eric, thanks a lot for the explanation and technical details.
Knowing this helps me a bit, as it confirms my observations. What is not clear, is how these shifts will/should (or would they?) be addressed?
I mean Recovery was a perfect control until now. it just did what is should, reliably and consistently. Now we have the side-effect of color shifts.
a) Will Adobe adjust the algorithm to fit the new profile system? A bad thing, because it will not assure backward compatibility.
b) Will Adobe add a new control? Worse, because it adds unnecessary complexity.
c) Will/could the profiles be modified in a way as these color shift don't happen. As I understand from your previous post, this doesn't seem possible.
d) Will it just be left as is and I'll have to live with the color shifts? Now it seems it's the most likely option. Sad, because Recovery used to be so powerful, and now its power is somewhat compromised.

Feature Request: Opcodes in DNG Camera Profiles?

We now have V1.3 of the DNG spec, with support for opcodes, which is great.
Now, can we the ability to put opcodes in DNG camera profiles?
Given all the hard work has already been done to support opcodes, this would seem to me to be a really value adding thing to do. It would allow profiles to be created that support specific camera/lens combinations. E.g., it would allow the Leica M8's famous "Cyan corners" vignetting problem on uncoded wide ange lenses to be addressed by a profile rather than having to rewrite all the image's raw data.
Thanks,
Sandy

The files are in this directory on my Vista machine and my Win7 machine.
How far do you get when you try to click down to that path in Explorer: C:\ ?
If so:
C:\ProgramData is a hidden directory.
You can enable visibility of hidden files and folders by going to:
My Computer / Alt-Tools / Folder options... / View
and near the top you will find Hide and Show hidden files options.
However, you can also just open My Computer and type c:\programdata into the Address area and hit Enter and you'll be in that folder despite it being hidden, then click your way down to where you need to be.

Camera Profiles and Lens Profiles are missing in ACR 8.2.

Yesterday I tried to install a new update for CS CC, but it failed. Then I uninstalled the app completely, and installed it again.
When I opened ACR 8.2 I found out that there were no Camera profiles and LensProfiles (as it used to be before). Instead of usual Camera Profile was Matrix. There were no Lens Profiles in Photoshop Lens Corrections either.
The folder C/.../App Data/Roaming/Adobe/CameraRaw/LensProfilesDefault was also empty.
I reinstalled the application a couple times with the same result.
How can I fix the problem?
Regards, Yulia

Well, C:\ProgramData\Adobe\CameraRaw\CameraProfiles\Adobe Standard is also completely empty.

Camera profiles and Untwisted Adobe Camera Profiles

If memory serves me correctly, mention was made a while ago about the Recovery slider within LR - basically how bad it was. Um? At this time, again if memory serves me correctly, someone mentioned something about 'Untwisted Profiles'.
Anyway, following a link from another forum I ended up here http://thomaslesterphotography.com/photography/untwisted-adobe-camera-profiles/ and thought I might just give it a go. However, I am unable to locate the folder in which Lightroom stores it's camera profiles. If I follow the route (in Windows), Documents and Settings, User, Application Data, Adobe, Camera Raw, Camera Profiles I only find a index.dat file which obviously isn't the correct place.
Could some kind soul kindly point me in the direction of where these Untwisted Profiles should be placed (Windows)? Curiosity is getting the better of me and I really want to (a) see what all the fuss is about (b) is it justified and (c) do these Untwisted Profiles really make a difference. Nothing ventured nothing gained eh`? lol

ElliR,
What a great move of Thomas Lester to publish all these profiles
About the installation:
Thomas refers to “C:\Documents and Settings\All Users\Application Data\Adobe\CameraRaw\CameraProfiles\Camera”, which is where LR (and ACR) stores its delivered profiles. You can put the untwisted profiles there, under your camera folder.
But, if you want to keep them separate (which I prefer), you can also put them into the user specific folder (this is also where LR puts its presets). In this case, create a folder Camera in “C:\Documents and Settings\your-user\Application Data\Adobe\CameraRaw\CameraProfiles” (this is where you found the file index.dat) and copy the entire folder for your camera from the ZIP file into that Camera folder.
In both cases, you'll be able to see the new profiles in the Develop Module.

P.S: These folder locations refer to WinXP. To find out your local presets folder for your OS, use Preferences / Presets / Show Lightroom Presets Folder.

Camera Profiles and Defaults

I have been using CS5 and am about to install CS6. For my two cameras, I set up camera profiles and defaults by ISO in Camera Raw. The defaults include initial noise reduction settings for each ISO. Will these profiles and defaults transfer to CS6? If so, can I assume the noise reduction settings will be comparable? Thanks.

IIRC, all of those settings did transfer when I installed Photoshop CS6. But I installed CS6 first and then removed CS5. This broke the external editor link in Lightroom, forcing me to install Lightroom 4 again to reestablish the link.
It's likely that you will have to redo your default settings anyway using the PV 2012 adjustments because they are quite different in some respects. Noise reduction is improved in the new version, so I think you will probably want to reevaluate your default settings.

Hi, Can anyone recommended software to import dvd to iMovies. I need to import about a dozen homemade DVD's and edit them into a single DVD comprising the 'best bits'. How best can I do this. I have an external hard drive available for the job

You need to convert the VOB files in the TS-Folder of the DVD back to DV which iMovie is designed to handle. For that you need mpegStreamclip:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
which is free, but you must also have the Apple mpeg2 plugin :
http://store.apple.com/us/product/D2187Z/A/quicktime-mpeg-2-playback-component-f or-mac-os-x
(unless you are running Lion in which case see below))
which is a mere $20.
Another possibility is to use DVDxDV:
http://www.dvdxdv.com/NewFolderLookSite/Products/DVDxDV.overview.htm
which costs $25.
For the benefit of others who may read this thread:
Obviously the foregoing only applies to DVDs you have made yourself, or other home-made DVDs that have been given to you. It will NOT work on copy-protected commercial DVDs, which in any case would be illegal.
And from the TOU of these forums:
Keep within the Law
No material may be submitted that is intended to promote or commit an illegal act.
Do not submit software or descriptions of processes that break or otherwise ‘work around’ digital rights management software or hardware. This includes conversations about ‘ripping’ DVDs or working around FairPlay software used on the iTunes Store.
If you are running Lion or later:
From the MPEG Streamclip homepage
The installer of the MPEG-2 Playback Component may refuse to install the component in Lion. Apple states the component is unnecessary in Lion onwards, however MPEG Streamclip still needs it. See this:
http://support.apple.com/kb/HT3381
To install the component in Lion, please download MPEG Streamclip 1.9.3b7 beta above; inside the disk image you will find the Utility MPEG2 Component Lion: use it to install the MPEG-2 Playback Component in Lion. The original installer's disk image (QuickTimeMPEG2.dmg) is required.
The current versions of MPEG Streamclip cannot take advantage of the built-in MPEG-2 functionality of Lion. For MPEG-2 files you still need to install the QuickTime MPEG-2 Playback Component, which is not preinstalled in Lion. (The same applies to Mountain Lion even though that has it preinstalled.) You don't have to install QuickTime 7.
