Tiffen 4 x 5.65-Inch Decamired Blue 12 Cooling Lens Filter | 4565DMB12
Ever fight with color temperature in mixed lighting, only to end up with images that look too warm or just? off? The Tiffen 4 x 5.65-Inch Decamired Blue 12 Cooling Lens Filter takes a different, more precise approach. It cuts through the orange cast from tungsten sources or warm ambient light, giving you a clean, cool shift without the guesswork. It’s not a vague “blue” filter ? it’s a calibrated decamired tool that works predictably in front of your lens.
You’ll notice the difference immediately in skin tones and shadow detail. The 12 cooling effect is subtle enough to preserve natural color, yet strong enough to correct strong golden-hour sidelight. This isn’t a subtle diffusion panel; it’s a hard-working optical glass filter that mounts clean in any standard 4×5.65 holder. Use it with your matte box, pack it for studio or location work, and trust it to deliver consistent cooling shot after shot. Simple, direct, and built for pros who don’t have time to warm things up.
