Of course there were many other such web sites, but these three had decent directions on how to tone using Photoshop. Paul Butzi's had a section entitled "Toning Digital Prints" which had several ways to perform different tones, one of them included using curves. Patti Anderson's post on the Adobe Community web site includes several gradients. It was for a much earlier version of Photoshop (7.x), but it does seem to work. The last web site that I found interesting was from Tom Nieman's ePaperPress web site. It requires a little more navigation, but the whole section on Black and White is worthwhile clicking through. By the way, some of these sites use older versions of Photoshop, but you can get the general idea.
So, using the information I gleaned from these web sites and the book mentioned above I made my first attempt at Selenium toning using Photoshop which is shown below. I used an image that I had taken in Silver Plume of the Georgetown Loop Railroad engine. The picture on the left is done using a curves adjustment layer while the other is via a gradient adjustment layer.

Did I succeed? To paraphrase an instructor of mine from the Denver Darkroom, I too remain skeptical. Both of the images print nicely, but my printing is still in the primitive stages. I will continue to work this out.
