Blacklight Lighting Setup Question

[lhmaloney]

I would love to replicate the look of the blacklight (kitchen) scene from the new Wiz Khalifia Video "BAKE SALE"

Warning language NSFW https://www.youtube.com/watch?v=rTAZlHGOVo8

I know obvious black lights, bright t-shirts, smoke machine and led lights in the background, but I'm trying to figure out how some of the detail is preserved in the close ups.

Was it a blacklight on camera, a ringlight geled?

How was this kitchen scene setup?

Thank you in advance

UV light comes in various forms now. The traditional type was quite a short wavelength - (have a read of this topic, on a theatrical forum, as it's a common feature) http://www.blue-room.org.uk/index.php?showtopic=65903

The discharge types produce hardly any visible light - so clearly the video didn't use these, or used a mix of UV and visible light - but I'd put the money on the new UV LEDs. The normal Blue - in RGB, and RGBW LED fixtures has quite a bit of UV content, making some material fluoresce. Now you can get RGBWA+UV LED units and their UV has less visible output. So you could use these, blast the UV channel at full, then bring up the others to give you a low level white, or orange colour like in the video. Many video people get a surprise when shooting with LED blue, discovering wonderful effects with certain costumes, and I wonder if the premise for that video was a happy accident that the producers heard about/had seen, and they just exploited these new light sources. You can't create UV fluorescence with gel - far too lossy. The choices at the moment are proper discharge types (similar to sodium discharge types) but with black glass. Short enough wavelength that you eye cannot focus on them, and neither can most video cameras. Fluorescent tubes tat fit in ordinary fixtures and are quite cheap. Fragile, and not as short a wavelength, with a little more visible light. Last is the LED UV - which has more visible light - still blue light, but visible blue. Lastly the multi element LED chips with other colours too. The amber is quite useful - a near sepia style colour that blends well to shift the white a little warmer.
