tone mapping

Tone mapping flattens all the exposure levels taken into a single image, using the best exposure available to produce a more balanced image.

The Spheron system is capable of taking upto 26 f-stop exposure values in a single scan (if required).

The proprietary ‘tone-mapping’ process the Spheron system employs works on a pixel by pixel basis, choosing the best exposure of each of the 26 (exposure) options, to produce an image very close to what the human eye can perceive / appreciate.

Banding on image is due to sun being masked by clouds occasionally.

Without ‘tone-mapping’ you would not get the balanced interior view and clouds / airfield through the open hangar door.
