Results from Lab2:

The generally best operator was the erik Operator 0. This makes sense, as the scaling for YIQ was done and then the entire YIQ was converted back.
The erik Operator 1 is a rather bad tone mapping operator, but I left it in the results as an example. It uses a scaling of the RGB by the converted Y
to the original Y. This yields a lot of hue problems. There ferdi did well generally, however led to some washed out/unsaturated looking scenes.
I observed that something between the ferdi and erik would be nice, so I decided to make an addition to the ferdi as an option and averaged the two operators.

One problem that all of the tone mapping operators I implemented had as that sometimes the specular highlights were incorrectly colored.

Here are jpg samples of the images. To view the images in their ppm/hdr format, they are at www.cse.ohio-state.edu/~herres/782 in zip format.

Leftmost image is HDR converted to jpg using GraphicConverter program. Next image is ferdi, then erik operator 0 then erik operator 1 and finally
is my new blended operator.
