The Tiffen 72mm Black Satin 1 Filter helps you decrease the overall contrast of a photograph and fine-tune the highlights in a scene. While this filter also renders highlights as grittier, grainier, this filter softens facial blemishes and wrinkles in an understated manner. The 1 density produces less contrast and highlight removal than the 2, but still has a warm and natural look with the Tiffen 72mm Black Satin 1 Filter.This filter is constructed from Water White glass and is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and mounting to precision metal rings. Offers greater control over highlights, reduces overall contrast, and produces a grittier, grainier appearance in highlight regions. Smoothes facial blemishes, wrinkles, and other textures for a natural look. Maintains clear focus and realizes a more filmic look than purely digital capture can otherwise record. Ideally suited for use with modern lenses and digital image sensors. Water White optical glass maintains high optical clarity.
