About Rosco

Converts 5500°K daylight to 4500°K. Used when slight correction is desired or when daylight is below 4000°K. Optically clear. (Mired shift = +42, Trans.= 81%, -0.3s).

Sun 85 & Neutral Density Filters are usually applied to windows for color correction and/or light intensity reduction. RoscoSun 85 is an amber filter that lowers the color temperature of daylight to balance with 3200°K sources. Rosco Neutral Density Filters reduce the level of exterior light and bring it within the exposure range of interior light levels. Two additional RoscoSun materials combine Sun 85 conversion with Neutral Density reduction. All materials are deep-dyed for optical clarity. Except as noted, all materials are extra wide 57" x 21' (145 cm x 6.7 m), sheets 20" x 24" (50 cm x 61 cm).

Great for flash


I use a small strip of this 1/4 CTO gel on my speedlite to get closer to sunset color. Looks a lot more natural than the bluish flash from the un-gelled speedlite, without making the model squint like they do with reflected sunlight or other continuous light sources.

A must have for the lighting kit


It's a simple product but a no-brainer if you're using HMI's, HID's, Flourescents or daylight sources (and most all digital sensors "prefer" daylight, adding gain - and noise - to the blue channel for tungsten). With the range of affordable daylight gear out there, green spikes and blue casts are all over the place. TEST your daylight sources and have a range of minus green (from 1/8 up) and CTO handy... and make note of which fixtures or globes need what. CTO is what you need for fixtures that are in the 6500k range - minus green will take the green spike from fluorescents. (And 1/8, 1/4, or 1/2 CTO is a nice color warmer, too).
