Have you ever struggled to get a decent white balance from a white or grey card with the Sony FX6, FX9 or in fact many other cameras (this method works equally well for the FS7, FS5, F5 and F55 etc)? Well here is a very simple trick that can really help, especially for those situations where the camera is a long way from the scene and a white card is too small in the frame for an accurate reading.
All you need to do is to cut a square hole in a piece of black card or plastic. Then when you want to take your white balance simply hold the mask in front of the lens so that it masks out the background of the shot leaving just your white card visible. It’s really simple, really easy and it really works!
