Black Light Question
Posted 07 January 2010 - 12:53 AM
Has anyone shot black light on a Red anything I should watch out for?
The black lights are 400 watt UV Flood Stage lights rented from a stage supply and touring company in Nashville.
Does anyone know what the lighting = would be in terms of a tungston light
Does 400w = 400w in black light
Any thoughts and help would be appreciated

Black light is outside the visible and shootable part of the spectrum, it works by getting converted into the visible range by certain materials. That process is very inefficient, so it'll be a lot less light than you'd get from a visible 400 Watt unit. In those small areas, though, it'll be a light source in frame, sort of like distant Christmas lights or neon signs.

I shot something recently with Blacklight (F35) and the amount of light you need or "exposure" is almost unfathomable (obviously i didn't realise this). A double 4ft Batton needed to be about 1/2 a foot away and the 400W stage lights we had were also quite limiting - direct at the talent from a couple of feet away.
Great for CU's - would hate to be doing a bunch of wide shots. Works really well with the white teeth and eyes - grab some fluoro paint and dabble it on things you want to pick out - but as John said - good its digital so you can actually see what you're working with.

Anyhow, this is all too complicated. The thing to do is simplify it by using the camera's histograms and the monitor.
