Greetings All,


Is it possible to use different camera profiles with Lightroom? Currently all I see is <embedded> and can not find any way to change that. I am thinking something similar to C1!

Kind Regards. Terry.

Unfortunately, no.  According to the Adobe folks (on the official Lightroom forum) the closest you could come, at least at this time, would be to establish and save certain presets.

My take is fortunately yes since the process is fraught with issues, expenses and often fails miserably. What we do need is a nice calibrate script as we have for ACR to tweak the existing "profiles" (They are not really ICC profiles).

Calibrate your display. Make the images look as you wish. Done. Numbers** and colors in the converter are what you get when you render the image. KISS.

**True for ACR. In LR, the numbers (percentages) are based on Melissa RGB (ProPhoto RGB primaries and white point, sRGB tone response curve). Then you can export into one of three standard RGB working spaces.

Thank you this works well for me. I couldn't agree more on KISS.

Best Regards. Terry.

What exactly is the problem (for users) of allowing third party profiles (e.g., Magne profiles for C1)?

The problems in building profiles are many. The fact that every product treats the camera like a scanner is just one of many reasons this doesn’t work very well, with virtually any off the shelf product a user would have to shell out money for.

The other reason is, it's mostly not needed! It's a problem in search of a solution. In the years that ACR has been around, I'm pretty convinced that the lack of a means to use a custom profile hasn't been an issue whatsoever. Since LR uses the same engine, I don't suspect nor see a reason to revamp the processing engine Thomas designed using his mix of 'input' profiles. But should any user feel the desire to spend the time and money to build profiles, there are plenty of other solutions on the market that will let you play in that sandbox.

A thread currently active on this forum "Achieve Better Reds" suggests that that there is indeed a "problem in search of a solution":

If there wasn't a problem, why would anyone go to the trouble of developing an ACR calibrator script to improve the color (as several have)?  Also, note that I am not suggesting building your own profiles as a good route, but having the ability to use profiles built by someone else (e.g., Magne profiles).

The script and the process are for tweaking the chromaticity values as a built in profile editor if you will. So you don't have to spend time and money on exotic targets and building profiles, you simply alter the rendering and build a new ACR default. Much faster and easier. With a custom profile, there's still a great possibility you'll need this tweaking functionality which isn't available in just about any other converter I know of. Again, the key here from a design perspective is KISS.

Thomas builds custom profiles for the sample camera he gets. IF like say a Pro Epson printer, all the cameras behaved the same, this wouldn't be necessary. The canned profiles Epson supplies are excellent because the devices are very consistent which apparently isn't the case with our camera systems. But the calibrate tab has the necessary controls to sync up these discrepancies in a very easy fashion.
