this tutorial is about increasing dynamic range with only a single raw image file.

take the shot:
set the camera to raw format image mode and shoot the picture. a single raw image contains enough color information (RAW: 3x12bit=36bit => 4096colors/channel, JPEG: 3x8bit=24bit => 256colors/channel) to reconstruct under- or overexposed image parts. alternatively you can take two jpeg images (one must be shot underexposed and the other one overexposed).

the unprocessed images in jpeg image format.
