Video lights as backlight for cam-scan of negatives with NLP.
I’ve commented before on the Skier CopyBox as a good backlight source. It plugs into wall power and is quite bright. I wanted to compare compact (e.g. 3x5") video lights, intended for hot-shoe mount. I compared three to the Skier and all produce excellent NLP conversions.
Skier CopyBox is the brightest, 1/150 sec at ISO 100, f/5.6, at 1:1, no adjustments. Price: $189, and now back in stock, version 2. The light panel is CN-T96, find it on eBay or AliExpress for ~$30, a bargain.
Godox LED-M150 video light, plastic, light weight, 1/50th sec. Brightness adjustment only. Price: $40, a bargain.
Boling BL-P1 video light, built like a tank, adjustable bracket, rechargeable battery, selectable color temp and brightness, 1/50th sec. Price: $159.
Aladdin A-Lite, the pro alternative, comes with a diffuser, rechargeable battery, selectable color temp and brightness. 1/30th. Price $430.
NLP: White Balance on unexposed film, Frontier, PreSat=3, Standard, Fuji, and a bit of Brightness adjustment.
