Vitozonchello and Phil Connolly, thank you so much for your kind answers!
I read the article about "28 Days Later" which in American Cinematographer. But I think they used anamorphic adapter for shooting. I decided using 1:1.66 mask on 4:3. What about that? Will it be good for short film? I'm planning send my film to some festivals.
I'm waiting your answers. :rolleyes:
