I've seen Transformers six times now.
Wow, I'm a dork.
I wanted to break down my personal IMAX viewing.
Sound was great! You could really hear the SFX and the score so much better and it made for a better impact.
Screen size really helps. There were things I didn't notice before and it was good to see on such a large screen.
Clearly noticeable black spots on the screen. Some moved during the show, others did not.
Sometimes it was out of focus, or "soft focus".
The screen was brightest at the top center of the screen. Using the white end titles as a reference point they got clear and pure white at the center and top of the frame while they faded to a less brilliant white in an oval shape pattern towards the bottom and edges of the shot.
I saw it at:
Santikos Palladium IMAX• San Antonio, TX
Thought Bay would like to know.
