Heliopan
77mm Light Red (25) SH-PMC Filter
Filter for Black and White Photography
The 77mm Light Red (25) SH-PMC Filter from Heliopan is designed to build strong contrast in black and white photography. It works to completely absorb the colours green and blue, making them darker. This creates dramatic skies, helps to increase the tonal difference between foliage and flowers, and can even remove haze from a black and white image. Infrared images can also be enhanced by the filter giving a moonlight effect.The filter uses Schott glass, to ensure your images are sharp and clear, with true colour and contrast. The SH-PMC multi-coating provides a total of 16 coatings, 8 per side, for significant reflection reduction (below 0.2%) as well as dust and moisture repellence for easier cleaning. It is finished with a dual-threaded brass filter ring for durability as well as jamming prevention, and the 77mm front filter thread permits combining with other filters. Please note that exposures should be increased by 3 stops due to the 8x filter factor.
