Hey Ted -- thanks. The image I posted is a scan of a negative. I toned it in Photoshop, which is why it looks kind of brown. I like for photos to look a little bit warm most of the time. I don't actually like Solo's expression in that photo so much as he's listening to something off to his right (note the cocked ears) and as a result, he looks like his mind has wandered off a bit and his eyes are a bit blank. But he is fun to take pictures of since he always looks handsome.

He's also fun to photograph because he is excellent at posing. I can get him to sit, stand, look straight at me and cock his ears, look back over his shoulder, whatever. One of the reasons I have a million pictures of Solo and very few of Fly (my other Border Collie) is that she's hopeless at posing, unlike Solo.
(not a Rollei photo, but I'm taking a Rollei photo in the picture)
As Frank noted, Solo has yellow eyes (they are green-gold, and very feral) so they show up really well in black and white. Actually, red Border Collies are quite ideal canine subjects for black and white photographs, light enough for detail to show up, with nice markings that people find aesthetically pleasing, and yellow eyes that pop.
Solo's a big part of the reason that I started taking photographs to begin with. Like some humans, he looks great in every photo I take of him, including the photos that in and of themselves are crappy photos. When you have such a reliable subject, taking photos is a pleasure.
