This 130 x 170mm Cokin X-Pro Series Hard-Edge Graduated ND Filter is designed for use with a Cokin X-Pro Series Filter Holder. It helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A neutral density filter with a hard-edged line of transition is useful for images which include defined horizon lines. Neutral density filters do not affect the coloration of the image and this filter provides up to a 3-stop reduction in light from entering a lens.

This filter is made of durable optical resin (CR39) and measures 3.0mm thick.

Q: 10. Solar Filter: Are any Cokin filters suitable to safely view & photograph the sun? I'm gearing up for this August's solar eclipse.

A: Unfortunately, Cokin does not have any filters that are designed for solar photography usage. However, if you own the Cokin Z-PRO filter holder, which uses 4 x 4 (100mm x 100mm) filters, then the LEE Filters 100x100mm Solar Eclipse Filter, B&H # LESE100, would work in your filter holder for your photographic usage needs.
