hi paul

you can shoot handheld, and have the image right side up use available light ...
use / shoot faster films and stop down ... too

look for a graflex slr or any of the slr type large format cameras ( they made them upto 5x7, and even a gowland TLR that is 8x10 )

you can put the camera on a tripod and view the glass with a dark cloth, or through the hood.
the graflex slrs are the most versatile large format portrait cameras made ...
i've had and used one for almost 20 years, and it is probably my favorite large camera to use .. portable too ...

good luck !
john

ps. nice portrait !
