The FotodioX 100x133mm Soft-Edge Graduated Blue Sky 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 blue to a hazy or colorless sky. When used instead of a polarizer filter to enhance the sky within an image, the desired effect can be applied only to the sky, without any unwanted polarization or additional contrast to any 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: 5. To get the most out of the battery life during a 2+ hour shoot of multiple testimonials, should I turn it down between subjects or turn it off?

Q: 8. 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.

Q: 9. How many LEDs is in this?

A: Fotodiox does not list the number of leds but please note this light uses leds that are reflective in that they come in from the side.They will have less than the front facing type.

A: Unfortunately, there are no compatible grids or softboxes for this particular LED light.
