The FotodioX 100x133mm Soft-Edge Graduated Tobacco/Sepia Filteris a filter designed for use with the Cokin Z-Pro series or FotodioX Pro 100mm filter holder systems. It can be used to add a tobacco and sepia tint to complement an existing sunrise or sunset within a scene, or to otherwise enhance a hazy or colorless sky. When used to enhance the sky within an image, the desired effect can be applied only to the sky, without any unwanted changes to any other part of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. This filter has up to a 0.6 density and reduces light from entering a lens by up to two stops.

This filter is made of durable, optical resin (CR39) and measures 1.6mm thick. A plastic sleeve is also included with the filter.

Q: 6. Regarding the output of the light, how bright is it at its highest setting? For example, it is comparable to a 500w light, 650w, 1000w, etc. in terms of how bright it can get

A: Wow, one guy says 65 watt equivalent, another guy says 650 watt equivalent. What a difference! Here is the definitive answer: An old-school 750 watt Lowel Tota tungsten light puts out 2,700 lux at 3.3'. This light puts out between 778 and 865 lux at 3.3' (depending on your color; 5600K mode is brighter than 3200K mode). That's ~30% as much light as the Lowel Tota or the equivalent of a 220-240 watt tungsten light.
