Lightroom - embedded profile?

Hello,

 

I can only seem to find conflicting info on this so I hope someone will be able to quickly put me out of my misery ;)

 

I usually use C1 but have just tried Lightroom. I'm used to he fact that M8/M9 DNGs have no associated profile and that C1 itself applies the specified M8/9 profile. Now, Lightroom seems to have two options for the M9: Adobe Standard and Embedded. Switching between them shows subtle variations.

 

It's not possible, of course, to assign a profile to a DNG in the M8/9 and so how can there be an embedded profile? What would it be?

 

Thanks in advance...

What I think they are suggesting is Standard corrections (Adobe Standard, what adobe thinks are good setting to start with) and embedded corrections Profiles (white ballance and the like). Not color profiles like Adobe RGB or sRGB or ProphotoRGB. those only get assigned when exporting the image to JPG, TIFF and PSD.

All DNG files have embedded in them the equivalent to an Adobe "Camera Profile" (aka DNG Camera Profile). The embedded profile is created by Leica. Note however that an Adobe camera profile is not a color profile in the sense of sRGB or Adobe RGB, it's a description of the characteristics of the camera.

 

So what you're getting is a choice between Leica's profile as built into the M9, and Adobe's profile, as created by Adobe profiling the M9. Your choice as to which one you use, but the Adobe profile is considerably more sophisticated; embedded profiles are fairly simplistic.

 

C1 entirely ignores the embedded profile for M8s and M9s - C1 profiles cameras in an different and mostly incompatible way.

Of course you can create your own adjusted profiles for both LR/ACR and C1.

For Lightroom/ACR you can either use Adobe's DNG Profile Editor which is a free download from Adobe Labs or you can use Color Checker Passport from x-rite. The latter will create a daylight, tungsten, or dual profile from a DNG of a Macbeth 24 color chart taken with the appropriate lighting.

In C1 you can save adjustments you make in the color editor as a profile.

To use created profiles in LR/ACR save them to:

user/library/application support/Adobe/CameraRaw/Camera Profiles

For completeness, LR/CS5 show "Camera Standard" as the profile for the M8 and "Embedded" as the profile for the M9. I have found custom profiles made using the Color Checker and Adobe DNG Profile Editor to be superior, particularly to get red in check. You can make a different profile for every lens in your bag.

 

I don't know why "Adobe Standard" is the one that is set by default in preferences. It is the worst profile of all. So once you have decided which profile to use, remember to reset your preference.

I read somewhere that the idea of "Adobe Standard" is that all your cameras can share it.

 

That is, if you're shooting Leica and Canon on an assignment, choosing "Adobe Standard" will line up the pictures from both so they pretty much match.

 

Don't know whether it's accurate, but I think it makes sense.

Zeitz you are a little confused in that post. If you go back and open an earlier image (in Develop module) that you developed with an earlier profile, that one is what will be displayed by default. For example opening an M8 image from early 2008 I now see Process 2003 and profile ACR4.4. That was just what I used at the time with the existing software version then and the process and profile can (and usually should) be updated if I was redeveloping the shot now.

 

If you are using LR3/CS5 The default values are Process 2010 and Adobe Standard for M8 and M9. You can as you noted change defaults if desired according to personal preference.

Lordy, this stuff is gettin' complicated.

 

 

Whatever happened to "You push the button, we do the rest"?

 

 

Oh, wait. These days, those guys make the Leica sensors, don't they? :rolleyes:
