Review: Keldan Spectrum and Ambient Filters by Massimo Franzese
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.
