Do you often use ProRes as a codec in your filmmaking process or when sending files to your client? Read this article made by my co-worker at Stopp, Johan Boije, about how unstable ProRes may be in terms of color and gamma shifting.

This test started out to check color fidelity with Apple ProRes and The Foundry products like Nuke and Hiero. We knew from earlier that results wouldn’t be ideal.Later we expanded the test to other video applications and encoding software to see what that would give us. The outcome was quite disturbing. A format most people believe to be stable in terms of color turns out to be not so “Pro” at all."
