Thanks, John.
I have another roll of FP4 in at the mo and shall get some Ilford Delta 400 through it next. Most of the shots were at 1/100 sec and apertures between f4.5 and f8 although the mug-shot was f16 @ 1/25 sec and I had the camera resting on the draining board. I need to take a flash pic or two and use the extremities of aperture and speed, which I shall, in time.
I'll consider a set of tubes so I can use my Canon EOS 5D Mk:1 and 40mm f2.8 pancake lens for copying. My set-up is just a fluorescent lightbox, a cardboard mask and sheet of glass with the copy camera on a sturdy Benbo tripod and aligned with a spirit-level. I move the light box beneath laterally for fine adjustment.
