The Tiffen 5 x 6" 1 Cool Blue Soft-Edge Graduated Filter helps to specifically add a cool, purplish-blue coloration to skies and other bright areas of an image while allowing a portion of the image to remain neutrally colored. The filter's coloring is densest at the edge and tapers to clear by the middle, with a soft-edged transition between the density and clear areas. The 1 color density provides less cool blue coloration than the 2 density filter.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. It measures 5 x 6" / 127 x 152.4mm.

Note: A vertical orientation filter's line of transition runs parallel to the short side of the filter.

1 Density Color Graduated Filter    Cool Blue Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a deep cool blue coloring to select areas of the image.

Graduated filter design keeps a portion of the image neutral, resulting in a more realistic look while allowing for the sky or other bright areas to take on the color of the density.

Q: 10. Will this replace any halogen bulbs?? If so, which ones?? Thx!

A: The Frezzi Extended-Time 3200K LED Warm Lamp for Dimmer Mini-Fill, B&H # FRET3000LEDW, and the Frezzi Extended-Time 5000K LED Cool Lamp for Dimmer Mini-Fill, B&H # FRET5000LEDC, are both designed for use with the Frezzi EyLight Body with Front Cap, B&H # FREL, which is also compatible for use with the BAB lamp, such as the Impact BAB Flood Lamp (20W, 12V), B&H # IMBAB. For this particular fixture, the bulbs would be interchangeable. While the LED lamps may also be compatible with other lamp fixtures that use the GX5.3 base, I cannot guarantee that it will be interchangeable with all lamps of this type/design, and it would be best to inquire with the manufacturer of your light fixture before using the Frezzi Extended-Time LED lamps in other fixtures.
