Anyone seen the movie in 3D to help us justify the 3D premium for getting this otherwise interesting sounding documentary in Blu-ray 3D?
Herzog uses the 3D to emphasize how the artwork was drawn to utilize the curvature of the walls. He argues that this was an early method of providing a sense of motion to the drawings. As you move in the cave and change your angle of viewing, the animals seem to move. Combined with the flickering light and shadow from torches, this was the caveman equivalent of cinema.
The photography and 3D aren't perfect on a technical level. Due to confined space in the caves, Herzog wasn't able to bring in professional camera or lighting equipment. He had to use consumer-grade cameras and hand-held lights. However, the effect he achieves is one of the more artistic uses of 3D to date.
