Well today I got tired of not having an image processor at hand, Photoshop is on another PC on the other side of the country.
So I looked on the web and found GIMP, an open-source project. The binaries can be gotten here:
http://gimp-win.sourceforge.net/stable.html
Don't know if anyone here uses it, but I was quite impressed, and it cost me nothing. Seems to have everything I used to use in Photoshop, though maybe not quite the ease-of-use.
For this rendering (from a color original) I used the green channel to create monochrome (like using a color filter shooting B&W), applied unsharp mask, then a light canvas filter. It does seem to have a nice selection of filters from the little playing I did.
