Walter Cronkite narrates this thirty-six minute documentary and his unmistakable voice adds another layer of prestige to wonderful film about America's current achievements in space. The transfer itself is quite beautiful, offering a richly detailed image that shows the benefits of large format photography. Additionally, the Imax photography creates a tremendous sense of depth in some sequences, which almost gives the image a 3D feel.
Colors are bold and strongly rendered without a trace of noise or smearing.
Blacks are perfectly inky, plus the contrast is excellent- just check out the shots of the Earth against the backdrop of outer space. Digital compression artifacts are well hidden throughout the film. Not only is the picture a winner, the Dolby Digital 5.1 channel soundtrack also scores very high marks. The Imax multi-channel soundtrack has been well mixed into DVD's standard barer to create a highly active and enveloping sonic experience. While Walter Cronkite's narration is locked dead center, the voices of the astronauts and mission control technicians are localized in the rear channels, lending an otherworldly effect to the space missions.
