having just watched the dark knight on blu-ray i have noticed the imax film footage is alot better than the 35mm camera footage. the imax footage is fantastic, more three dimensional and clearer. the film shot in 35mm is no slouch either and is superb,but can see the difference in quality straight away.who knows in the future imax cameras might get cheaper to film and we get full screen film footage on our tvs instead of letterbox ratios any views or ideas on the matter technically would be most appreciated.
