CTB filters offer you complete control when shooting under tungsten lighting.

              I use this with my Arri fresnel kit. Works great to balance for daylight or to simulate cinematic moonlight. No complaints!

                  I am a Professional Video Producer and these are perfect size for my 500w lamps and are not badly priced. 1/2 blue is a good type to buy for basic lighting color correction. Full blue can be achieved by simply doubling up a piece.

                                      This is a standard half blue gel that I got to correct my halogen Tota light to go with flourescent lights. It works fine and is not too expensive for a piece of colored plastic.
