The effect is produced by re-exposing the same frame of film through red, green and blue filters in turn, while keeping the camera steady.

On top of those lamps is an array of tiny red, green and blue filters.

"In some ways there's no looking back once you start looking at everything through that green filter," he said.

Red, green and blue filters are arranged in a pattern.

Everywhere the jungle presses up close to the windows, making them into green filters.

Maxwell's idea was to take three separate black-and-white photographs through red, green and blue filters.

Each exposure was made through a red, green or blue filter to create a master for each primary color.

The final color image was assembled from individual exposures taken through blue, green, and red filters.

The picture released today was taken with a green filter but is black and white.

Data from the panoramic camera's red, green and blue filters were combined to create this true color image.
