Cokin colour filters are technical tools that are perfect for achieving various results, including: adding warmth to portraits, correcting colour casts, suppressing excessive brightness, eliminating the green cast of fluorescent tubes, simulating night shots in daylight, controlling the conversion of colours to greyscale in black and white photos, and blocking UV radiation. They are also suitable for taking analogue or digital infrared photos. This size is designed for lenses with a filter thread of up to 112 mm and is recommended for focal lengths of 35 mm and longer (based on 35 mm full frame). Use filters for light and colour control directly in the RAW file while shooting. Maintain the highest image quality, as there is no need for post-processing, and create special effects without time-consuming work on the computer.
