Lightroom 3.5 RC and Olympus E-P3: Wrong white-balance on aqua shots

Lightroom 3.5 RC and Olympus E-P3: "As shot" white-balance on specific shots (for example a photo of fish inside an aquarium) is totally off compared to the (correct) camera auto white-balance.

I uploaded the RAW of an example, the corresponding out-of-camera JPEG and the JPEG generated by Lightroom here: http://dl.dropbox.com/u/2049133/lr-aq...

I think this is a camera-profile issue, not a white-balance issue, since most of the image is reasonably similar, just the brightest, clipped areas, have odd coloring. The camera's clipped areas turn cyan, while Adobe's clipped areas are either magenta or cyan.

It is also an advertisement for why a camera-manufacturer may be better at optimizing their camera profile for their cameras, as opposed to Adobe which is trying to make things look the same across many cameras across multiple manufacturers.

Is the camera set to do any particular optimizations for highlights or scene colors?

Steve, thank you very much for your reply!

I'm sorry - you were right, the camera was set to boost the primary color a bit ("iEnhance" Mode was on "low"). However, setting the picture mode to "neutral" via Olympus Viewer 2 (= Olympus software to render their RAW files) didn't really change it that much. I made some more example JPEGs with Olympus Viewer 2 and Lightroom 3.5 RC, this time using different standard white balance settings and completely turning off any other image adjustments like contrast, extra saturation, sharpening, etc. (in Lightroom everything back to default values, in Olympus everything to "0", "neutral" - screenshot of the settings used is included).

While the Olympus files look "okay" with every WB setting, the Lightroom files show a) quite different colors and b) blown highlights in unfitting Magenta (the colors and highlights can be fixed by setting WB in Lightroom to 11500K and Tint -100 as in my first example picture, or by reducing exposure to at least -1.00).

Do you think there is something more I could add? Is this something, they would fix, or just expected behaviour ("Adobe colors" vs "Camera-maker colors")?

Adobe may tweak their camera profile for the EP3, but for an extreme color situation, what we're talking about is similar to the discussions about a sunset shot whether the sun has the proper transition from red through orange to white, or if there is a hint of green or gray in some of the brightness gradient, and likely won't be changed unless there is an underlying defect in the profile for more regular lighting situations.

To optimize a sunset shot from my Canon DSLR, I'd try using one of several camera-match profiles to reduce the green. Adobe only makes these extra profiles for Nikon and Canon cameras, usually.

It is good that you linked your RAW photo. That way if Adobe wants to take a look at the profile they can use your file for testing.
