Lee Filters know that when you shoot digitally, light at the infrared and ultraviolet ends of the spectrum can be problematic. So the Lee Filters ProGlass range of filters has been designed with this in mind.
These glass neutral density filters are optimised for use with digital cameras, as they absorb more infrared and ultraviolet light than traditional ND filters. The result is a punchier image, with less discoloration in adverse lighting conditions.
Lee Filters state that the ProGlass ND filter is an extremely high quality glass ND standard filter optimised for use with digital cameras, but equally useful for film.
This new filter uses a surface coating made from evaporated metal, and therefore provides very even absorption across the visible spectrum and through the UV and Infra Red regions.
Two filters are currently available for sale.
0.6 ProGlass ND Standard
A glass filter that reduces exposure by 2 stops without affecting colour balance.
0.9 ProGlass ND Standard
A glass filter that reduces exposure by 3 stops without affecting colour balance
