| 1. A high dynamic range image editing system for editing a high dynamic range image file having pixels spanning a first range
of light intensity levels on an image editing system that only displays differences in the light intensity levels of pixels
within a second range of light intensity levels that is less than the first range of light intensity levels, comprising:
a) a scaling control operable by the user that allows the user to enter one of several scaling factors;
b) a scaler in communication with said scaling control configured to create a scaled version of the image file that has pixel
intensity levels that are scaled from their original values in accordance with the entry made by the user on said scaling
control;
c) a display configured to display the scaled version of the image file which only displays differences in the light intensity
levels of pixels within the second range of light intensity levels which is less than the first range of light intensity levels;
and
d) an image editing system configured to edit the image by editing pixels in the high dynamic range image file and configured
to cause the scaled version and its display by the display to be updated with the edits that are made to the high dynamic
range image file substantially concurrent with the edits that are made to the high dynamic range image file.
