Paper neg test
This bow was part of a shop window display. You can't tell how big it is from this shot so let me tell you, it's BIG. I lit this with one Bowens Quad X 3000 head through a strip softbox, 2 full power flashes from a 2400 W/s pack. I decided to shoot this without any kind of test shot, polaroid or any other means of previewing apart from the modelling light on the strobe. I'm pleased with the result.
Camera: Toyo 10x8
Lens: Nikon 300/f5.6
Film: Ilford multigrade rc glossy paper with a grade 2 filter.

10x8 paper neg test
My first test of using paper instead of film.
Ilford Multigrade RC with a grade 2 filter on the lens. The detail in the hi-res scan is impressive.
Many thanks to Tim Layton for his advice and inspiration for trying this.
