Thanks, Don. I actually positioned him in a different spot and set up the camera the parallel to the organ so the lines would be square, but as expected, he wanted to get up and push all the buttons, and fortunately the Sinar P is quick to work with, so I just adjusted the camera, refocused, used a little rear swing, and went with it. Of five shots from this shoot, I generally like the more dynamic ones after he decided to get up and move around.
The lens, by the way, is a 10"/f:4 Voigtländer Petzval lens at f:22 from around 1860, for those who are curious about what a Petzval looks like stopped down. As Jim Galli attests, this is another reason to shoot 8x10" for portraits. You can use historic lenses that make interesting contact prints with a big neg, but don't necessarily hold up well to enlargement from a smaller format.
I haven't made a final print of this yet, because I want to try it with the new Lodima paper. This one's on Azo G2, and I did a little etching on the neg to tone down that front leg a bit as well as some highlights on the organ bench that you can't see in this crop.
Which, coming back to the general topic here, is another reason to shoot 8x10" for portraits, as DF Cardwell and others have mentioned above. The classic Hollywood portraits were as much about retouching as lighting, posing, format, and camera technique, and it's much easier to work with a big negative, so that's become an often unacknowledged part of the "large format aesthetic" as well. I suspect that virtually all studio portraiture from the 1890s to the 1970s involved retouching, and much of it still does.
