Unravelling some movie mysteries
French magician and filmmaker Georges Méliès turned a pumpkin into a carriage (Cinderella, 1899) simply by stopping the camera, changing the object he was filming, and recording again.
Cinematographers combined scenes that were shot at different times by concealing part of the film using a ‘matte’. In The Great Train Robbery (1903), footage of a moving locomotive was combined with footage of a robbery.
The glamorous glow of silver screen starlets was actually achieved using Vaseline. Applying a little petroleum jelly on the camera lens created a soft-focus, dreamy effect.
The first ever Technicolor blue-screen featured in The Thief of Bagdad (1940). By combining the blue and green negatives to create a solid matte, the film could be combined with new footage shot against a blue-screen.
