This question already has an answer here:
I have an Olympus E-PL2 and am taking photos in raw. I have the codec downloaded from Olympus, so I can view the photo with Picasa in Windows, and it looks fine but a few seconds after loading the image, it goes and does something in which it looks like it desaturates the whole photo. What is going on? I know there are many posts asking 'what is a good raw viewer' but I'm looking more for a solution for Picasa if possible since I use it for all my photo management.
