Michael Bay Shooting TRANSFORMERS 4 With New Small Form Factor 3D IMAX Cameras
Essentially Bay said that IMAX has given him very expensive, new small form factor (Bay shows us the size using his hands) 3D IMAX cameras to use on TRANSFORMERS 4. To top that off, there is so much data streaming out from these things (VERY high resolution), that Bay's finishing company would not be able to handle it all if he was to shoot the movie in this way. That's saying a lot knowing that Bay does NOT use cheap services. So, Bay will only be shooting key scenes with these cameras for TF4.
Bay also revealed that he will not be shooting in HFR (high frame rate).
Here's the interview from Collider - enjoy!
