I have added the original photo to the picasa album.  I hope it's
enough to link to the album for you to see them.

The images were generated by using the levels dialog (Colors ->
Levels) in the GIMP and through the Adjustments dialog in Shotwell.
For both of them I selected the region where the first large "hill" in
the histogram peaks on the left-hand side, about 51 in the GIMP, and
the beginning of the hill on the right-hand side of the histogram,
about 209 in the GIMP.

For some reason Shotwell's adjusments come out looking less saturated.
 Shotwell also handles clipping oddly and I can come up with an
example of that soon.

Let me know if there's anything I can do to make this clearer, and I
really appreciate you taking the time to help me out on this!

Thanks,
Conrad
