Then good thing I'm not your DP. I'm pretty confident in my skills, so thank you, I don't need your opinion about that - especially without you seeing any of my work. The film is a graduate film in film school, and I've shot a few already. I asked about aspect ratio just because there isn't a lot of awareness here to that subject. Most of the cinematheque's screens here are 1.85. We hope the film will be screened in festivals around the world as well though, and I'm wondering what's the best format for it. My main problem with 2.35 is the major crop it gets if we broadcast the movie on T.V. Regarding the F55, we might be able to lend it for free, I wouldn't rent an F55 if I don't have the budget for HDDs. I'm in the process of checking if I need a master in 4k, for the meanwhile the main benefit is the extra detail.
