Rosco 3408 1/2 CTO Amber Gel Sheet

The Rosco 3408 1/2 CTO is a precisely formulated color correction gel that shifts a daylight-balanced source approximately halfway toward tungsten — from roughly 5600K toward the 3800–4200K range. In practice, that means warmer skin tones, reduced blue harshness in open-shade scenarios, and a natural golden quality that reads well on camera without triggering the heavy amber cast of a full CTO conversion. It is the correction choice when you want light that feels warm and inviting rather than analytically neutral, and it is particularly effective as a matching tool when combining daylight and tungsten sources in a single setup.

Rosco's Cinegel formulation is produced to tighter color tolerances than commodity gel stock — consistent from sheet to sheet across production runs, which matters when you are gelling multiple fixtures and need them to match. The material is heat-resistant enough for extended use on fresnel and HMI fixtures, resistant to the color shift that plagues cheaper gels after a few hours at temperature. The 20x24 inch sheet cuts cleanly and handles like professional material: no curl, no static issues, no off-gassing at normal operating temperatures. A staple of the professional lighting kit, the Rosco 1/2 CTO earns its place through consistent, predictable performance in conditions where color accuracy is non-negotiable.
