A Model for Simulating the Photographic Development Process on Digital Images

Example Images

This page contains links to high-resolution versions of the images in the SIGGRAPH 97 paper A Model for Simulating the Photographic Development Process on Digital Images by Joe Geigel and F. Kenton Musgrave.

Unfortunately, the images in the final version of the paper as printed in the proceedings does not really do the model justice. These higher resolution version of the images will give a better idea of the results produced by the model.

The links point to TIFF images and correspond to the examples described in Section 6 of the paper.

For best results in viewing the image, it is recommended that images be displayed on a high resolution, 24 bit color monitor. The gamma of your monitor should also be adjusted so that that following gray ramp appears linear.
