Summary: Another Rip-Off From Slingshot
Review: After arguing with Slingshot Entertainments customer service person, I emailed her boss.He advised me that they were re-mastering this dvd, and reissuing a new version. He then sent me the new version, and it is a 100 percent improvement. The dark and grainy version that showed the segments of the imax screen has been replaced by a first class digitally remastered version. The cover looks different than the original. If you have problems, contact Slingshot Entertainment and request they replace your old version with the new. Thanks to Slingshot for doing the right thing.

Summary: Disapointing video hampers film
Review: After the spectacular IMAX "Super Speedway" I looked forward to this DVD, but was sorely disappointed. Many shots have the look of being filmed a little soft, then digitally sharpened, producing a nasty ringing along edges. Also, the camera is clearly vibrating during many static shots, leaving the picture trembling and hard to watch. Moving shots are generally good, though the print shows evidence of dirt and streaks. Narration is pompous, and the attempt at narrative is like the worst educational films. Even the packaging has problems, listing chapters and times for the documentary supplement incorrectly. The only bright point was the sound, which was a quite good Dolby Digital 5.1 channel mix.

Summary: Spectacular and wonderfully photography - stunning!
Review: As a lover of both world travel and photography, this would have to be one of the best of the IMAX films that I have ever seen. The use of camera movement and the composition of shots and sequences are stunning. To enjoy places like the Grand Canyon and the Iguacu Falls in South America can be relived many times over with such spectacular documentary making - and on this large scale. Wonderful.

Summary: Horrible image quality
Review: I bought this video after a visit to the Canyon and I am very sorry I did. Even with the cheapest vidoe camera you will get better image quality. There is a problem with image sharpness as well as colors. The conversion from IMAX to VHS PAL just killed the pictures. On top of that there is some sort of stupid story that we could do well without. Dont't buy this tape!

Summary: Grand Tour Of The History Of A Canyon
Review: I have the Slingshot edition (DVD9804) of this IMAX video. The print quality is pretty good but as a few others have mentioned there are one or two scratches and marks on the print used to make this DVD which is a bit disappointing considering on the back of the case it says the title was digitally remastered. I thought that would have been the time to fix such problems. When I saw this film at my local Imax I thought it looked a bit dark. I was told by the manager that early Imax cinemas used silver instead of white screens. (Anyone know if this is correct). Early Imax films also used a different film stock (?) which resulted in the dark look on the white screen. I don't know if this effects the look of this DVD or not. Apart from the one or two little scrathes it looks rather good throughout. A 4,000 year History of the Canyon, most it European history of the last 500 years, is used to link endlessly beatuiful shots of the Canyon together. Much of the middle section of the film is a ride sequence down rapids. Its spectacular and I assume would have been extremely dangerous to film. It certainly looks dangerous. Lots of helicopter shots, some nicely executed re-enactments and thats about it. There is however a nice link between an early sequence and the end of the film which ties up the narrative nicely. Worth getting if your never likely to get to the Grand Canyon yourself. I would have liked an ambience and music option on this DVD, but sadly its not there. There is an additional 9 minute making of featurette on this edition which shows how difficult films like this are to make. Keith Merrill also made Niagara: Miracles, Myths and Magic, which is done in exactly the same style as GC.

Summary: One of the best IMax
Review: I saw this at an eye max after leaving the park. I loved it.
I own practically every eye max. This one is very good. I do not know why other people have rated it poorly. I guess you will have to trust your instincts on tyhis one

Summary: Grand Canyon imax Disappointing
Review: In my home theater I project dvd large screen images with a RUNCO DLP projector. Nearly all dvd's are movie-theater- quality in their clarity. However, the image quality of Grand Canyon was very poor and not up to IMAX standards at all.

Summary: Not the same quality as the IMAX theater.
Review: My dad bought this DVD in Arizona after watching the presentation at the IMAX theater but he was disappointed when we watched it at home on our Sharp LCD projector (on a 5½-foot screen). The video quality was VHS-level at best and not even close to what we've become accustomed to from DVD's. The film seemed grainy and the colors were not as distinct and lifelike as they had appeared in the theater. The audio quality was pretty good, but the narration was a bit on the dull side. The camera shots were done pretty well but we were looking forward to more helicopter fly-by shots through the Grand Canyon itself. I hope they re-do this video from scratch and stick to the high-quality film that IMAX theaters are famous for.
