Breakthrough Photography 150x170mm 3-Stop Hard Reverse X4 Graduated Neutral Density Filter

A revolution in photographic technology, the 150x170mm 3-Stop Hard Reverse X4 Graduated Neutral Density Filter is the world's sharpest and most color-neutral GND filter. This high-quality, durable filter is crafted from tempered SCHOTT B270 optical glass, made in Germany, ensuring exceptional clarity and precision in every shot.

The X4 GND filter, a product of Breakthrough Photography, is designed to increase the dynamic range of your camera, transforming your sunset photography from blown-out highlights to images bursting with incredible dynamic range. This is achieved in-camera, eliminating the need for post-processing techniques such as Photoshop, stacking multiple frames, or HDR.

Outdoor photographers often grapple with dynamic range, as the human eye can perceive over 20-stops, while a mid-day outdoor scene may range between 15-18 stops. Professional camera systems range between 12-14 stops. The X4 GND filter helps bridge this gap, expanding your in-camera dynamic range by decreasing highlight zones, similar to the Zone System by Ansel Adams used in the darkroom.

The X4 GND filter ushers in a new era of durability and resolving power with its SCHOTT B270 optical glass. This incredibly durable filter glass is resistant to breakage, even when dropped onto hard surfaces. Its impressive structural hardness also prevents warping, a common issue with traditional resin filters, especially when not stored flat.

The X4 GND filter is also equipped with state-of-the-art MRC16 and nanotec coatings technology applied to both sides of the optical surface. This reduces surface reflection and makes handling and cleaning the surface of the glass easy. The nanotec coatings also allow the X4 GND to glide smoothly in the holder.

Each X4 GND filter comes with a protective diamond case. These cases are not only durable and easy to use, but they also prevent damage when in your bag and come in unique colors for easy identification.

In summary, the 150x170mm 3-Stop Hard Reverse X4 Graduated Neutral Density Filter offers a versatile and effective solution for photographers looking to enhance their dynamic range in-camera and capture stunning, high-contrast scenes with precision and ease.
