Tiffen 52CGB 52mm Graduated Blue Filter

The Tiffen 52mm Graduated Blue Filter (52CGB) is designed for photographers who want to enhance sky tones or add a creative blue color wash to the upper portion of their images directly in-camera. Built using Tiffen's ColorCore technology, the filter sandwiches the color layer between two pieces of optical glass, which protects the tint from scratching, moisture, and fading over time. The graduated design means the blue is concentrated at one edge and gradually transitions to clear, letting you position the color effect over the sky while keeping your foreground naturally rendered.

Threaded at 52mm, the filter screws directly onto compatible lenses and adds minimal weight at just over two ounces. It is manufactured in the United States and maintains Tiffen's reputation for consistent optical quality. While modern post-processing software can replicate color grading effects, the 52CGB appeals to photographers who prefer to achieve the look in-camera or who want to reduce editing time. It is worth noting that because the graduation line is fixed in a circular filter, rectangular filter systems offer more control over where the transition falls in the frame.
