Two years in the making, the ProGlass IRND range from LEE Filters sets a new standard in neutral-density filters.
ProGlass IRND filters were originally designed for the film industry, to meet the exacting needs of the world’s leading cinematographers, and have already been hailed as the best neutral-density filters on the market. Now, they are available to the stills photographer, in sizes to fit the LEE Filters Seven5, 100mm and SW150 systems.
Advances in coating technology mean that the filters, which are manufactured from 2mm-thick, optically flat glass, are available not only in strengths of two (0.6ND), three (0.9ND), four (1.2ND) and six (1.8ND) stops, but also in ultra-long 10 (3ND) and 15-stop (4.5ND) versions. Not only this, but all filters in the range – whatever their strength – are designed to be free of colour casts, with extremely accurate stop values, ensuring consistency in all shooting conditions and allowing for absolute precision when exposing images. Their neutrality also means less time spent tweaking colour balances in postproduction.
In addition, filters in the ProGlass IRND range are designed to block both infrared and ultraviolet pollution. As a result, blacks are rendered truly black, whites are clean, and results reveal a crispness that is second to none.
The 6, 10 and 15-stop versions of the ProGlass IRND filters come with a foam seal to prevent light leaks during long exposures, and should be placed into the filter slot closest to the lens. While the 2, 3, 4 and 6-stop versions do not feature a foam seal, it is still recommended also to place them into the slot closest to the lens.
All filters in the ProGlass IRND range can be used in conjunction with other filters, including neutral-density grads and the polariser. They are available to purchase through the LEE Filters dealer network.
