Only one of three flashes fired. The sync speed on the old Pentax 67 was 1/30th of a second and I was hand holding the camera. One side is over exposed while the other side is wildly underexposed. When I tried to print the negative nothing really worked. And yet, years later I've realized that I really like the image. It has an energy that perfect portraits rarely achieve.
I'm glad I didn't have Polaroid or instant review because in my pursuit of "correct technique" I would surely have thrown away the image and moved on. I have many technically correct images that are much less interesting to me. The camera doesn't have to be an exacting Xerox machine in order to make your own art. Not always.
