Found a negative of one of my godsons. Back in the early days of photography I used to use a light setup for portraits. Then I found that flash with an umbrella gave a good modelling light although I did not get a back light.
Over-run bulbs didn't last long while flash would go on with no problems.
I had a Mecablitz that normally used a small accumulator but also has a mains connection. Used to do a lot of baby pix with that and my old Pentax S3 and the f1.8 85mm Pentax lens.
Ilford Panf film and Beutler developer was a good combination.
