That's a calibration. The image data is then adjusted into a form where assigning an sRGB profile will make the image look pleasing. (in the newer version it's a bit more complicated, but it's still not a profile). > > Then we export (process) those mosaic files into > TIFF files, choosing at that time which colour > space (sRGB, aRGB) is appropriate for the job.

You can use inCamera to build a profile, but chances youi'll get it to match your Sinar cameras are less than slim. If however, when you have access to a working version of CaptureShop v5. And you use the new Gretag Macbeth camera module, you can not only get the Fuji inline you can get something that will almost appear identical. And you have the option of choosing the "look" you prefer for all the cameras... > > Is it the consensus however that inCamera, or > Bruce Fraser's methods (using the same Macbeth > checker) would not do this? I seriously doubt it.
