The Rogue Colour Correction Filter Kit v3 is a versatile package that provides an array of different coloured gels that will help to improve and/or correct your flashgun colour balance to match the light source in your chosen scene. It comes with a colour correction reference chart that will help you accurately chose what is best for you, as well as a case to carry it all. This system has been developed to be compatible with most flashguns on that market - It comes with two sizes of gel bands that wrap around the flashgun, making it easy to set up and pack away.
