This is a short little test I did on my roof. Not scientific by any means, and not everything matches because the light was fading fast and I didn't spend the time grading to match shot to shot. The only grading I did was add the film convert look and tweak contrast a little on a shot by shot basis. I also used a 3-way color wheel to pop skin tones and accentuate some of the cool fill light in the shadows.
THINGS I LEARNED: The film convert Red Profile works much better than the Alexa. I think the Alexa is slightly green usually and the Epic is slightly magenta usually. Which means when I used the Alexa Look Profile my image turned magenta. I think the F5 leans a little towards magenta similar to RED, so that profile worked best. Unfortunately they do not have an F5/55 specific Look Profile.
Also, film converts 3-way color wheel is very annoying to use. I do not recommend using that for adding contrast/adjusting colors. I used it for this, but found it very cumbersome...
