Well, my current understanding is that I need to generate a TIFF from the raw file with that app without the app applying any corrections or profile. That results in a very dark image as no gamma or other other modifications are applied (this is the TIFF I put on the web site). So it might be the app is applying an additional boost or just gamma on top of the profile to get to proper exposure values and if the profile tries to do it on its own, I get overexposure. I tried boosting exposure in linear mode to get close to 100% and the resulting profile seems to be fine. But I am worried that this boost will result in a profile that might lead to problems elsewhere later on. cheers afx -- http://afximages.com/
