The company I work for recently upgraded their warehouse light source from metal halide to LED. So I saved one of the (rather big and very heavy) units from the metal skip and salvaged all the spare 400W bulbs that were no longer required. I thought it might be a useful light source for certain wet plate collodion subjects – still life scenes in particular.
A few months ago I found the time to try it out with a few old bottles sitting on top of a wooden box. I used an old piece of red material as a backdrop.
It worked pretty well.
Some technical details:
Exposure time: 45s
Lens: Schneider-Kreuznach Symmar-S 150mm f/5.6
Camera: Sinar Norma 5×4
Light source: 400W Metal Halide Single Bulb
