It’s a common problem. You are shooting a performance or event where LED lighting has been used to create dramatic coloured lighting effects. The intense blue from many types of LED stage lights can easily overload the sensor and instead of looking like a nice lighting effect the blue light becomes an ugly splodge of intense blue that spoils the footage.
Well there is a tool hidden away in the paint settings of many recent Sony cameras that can help. It’s called “adaptive matrix”.
When adaptive matrix is enabled, when the camera sees intense blue light such as the light from a blue LED light, the matrix adapts to this and reduces the saturation of the blue colour channel in the problem areas of the image. This can greatly improve the way such lights and lighting look. But be aware that if trying to shoot objects with very bright blue colours, perhaps even a bright blue sky, if you have the adaptive matrix turned on it may desaturate them. Because of this the adaptive matrix is normally turned off by default.
If you want to turn it on, it’s normally found in the cameras paint and matrix settings and it’s simply a case of setting adaptive matrix to on. I recommend that when you don’t actually need it you turn it back off again.
Most of Sony’s broadcast quality cameras produced in the last 5 years have the adaptive matrix function, that includes the FS7, FX9, Z280, Z450, Z750, F5/F55 and many others.
