Simon, Way back when I used to use the Hosemaster on rv's and custom vans. It was film back then so it was harder to combine images (digital retouching was still an infant and really pricey) It was really fun but really hit or miss. I wasted a lot of time playing with that thing, but at the time I was the senior in-hose photographer for a Boat/RV/Custom Conversion van company, so I had a lot of freedom to play. I'll see if I can find some old samples.
You ended up with a very nice result.
The problem I would have using it now is I no longer have a studio to shoot in. Its all location now, usually at the end of the production line or in a parts warehouse in some factory. No way to control the ambient lighting. I use a lot of parts and pieces in my current work and strip them together in post, but is all generalized lighting from strobes.
But its really cool seeing this technique in action again!
