What is the Minus Green card used for?
Cheap fluorescent lighting usually has a green cast to it – thus, distorting colors and making people look unhealthy. This is a common problem at places such as car dealerships, factories, airports, schools, retail stores, office buildings, supermarkets and hospitals. Many shooters work under the mistaken assumption that a “normal” white balance will compensate for the greenish tint of these kinds of lights — but it does not. This unique card removes the greenish tint you typically get while shooting under common fluorescent lighting. If you think ordinary white balancing compensates for the green hues of fluorescent lighting, you’ll be very surprised to see the difference that the Minus Green card makes. Colors are truer and skin tones look healthier.
