While the process I outlined in my previous column works just fine in this situation, a more accurate solution needs to take into account one of the F55's newest features: the ability to load in 3D Lookup Tables (LUTs) for viewing on set. Until now, 3D LUTs have mostly been used in post-production applications, but with this new function, they can now be used on set with no additional hardware. In fact, this feature is so popular it's showing up in more and more cameras, such as the Arri AMIRA and Panasonic VariCam 35/HS.
For more details on 3D LUT support and the the newly-released tools to make working with them even easier (such as Arri's AMIRA Color Tool) - as well as how I finally got the F55 and the C500 to match - read my newest Help Desk article over at HDVideoPro.
