Daniel Keller shares more of his extensive knowledge about capturing color underwater. In this episode of Wetpixel Live with Adam Hanlon, he discusses how filters can be used to balance out the spectrum of light captured by still and video shooters.
Massimo Franzese (aka Interceptor121) presents an extensive review of the performance of and an outline to the theory behind Keldan’s redesigned Spectrum and Ambient light filters. The former correct the color entering the lens of the camera, while the latter corrects the output of video lights. Massimo used the filters extensively during recent trips to Tiger Beach in the Bahamas and the Mediterranean.
Underwater lighting experts Keldan lights have produced two short animated videos that show how filters can be used to improve the quality of both ambient and video lighting. They also serve as an excellent primer on underwater lighting and the issues associated with it.
Inon has announced a new filter system that allows the user to adjust its strength underwater. The UW Variable Red Filter has an M67 mounting thread and is designed to correct the blue color cast in blue water. It operates with two coloured circular polarising filters that can be rotated to adjust their intensity.
