Cokin A21 Dark Blue Conversion/Cooling Filter (80B) A-Series

It's time to enhance your photography with the A21 Dark Blue Conversion/Cooling Filter (80B) from the renowned A-Series by Cokin. This high-quality, single-coated blue filter is expertly designed to suppress or significantly reduce the overpowering orange hues often caused by tungsten or halogen lighting.

Unlike ordinary filters, the A21 Dark Blue Conversion/Cooling Filter doesn't just provide uniform flashlight photos. Instead, it adds an intimate and atmospheric touch to your images, creating beautifully sculptured shadows without altering the original color tones. This makes it an ideal choice for capturing party lights, shop windows, and illuminated monuments in a whole new light.

The A21 Dark Blue Conversion/Cooling Filter is specifically designed for use with daylight film under tungsten lights, offering a unique cooling effect that can transform your photography. For those shooting under halogen lights, consider pairing this filter with the medium blue A021 or light blue A022 from the same A-Series for optimal results.

Crafted from blue glass and boasting a rectangular shape, this filter is part of the innovative Cokin A-Series filter system. This system allows for effortless stacking and swapping of filters, providing photographers with the flexibility to adapt to changing lighting conditions.
