12 White Balance and Gel Usage > Using Gels with the SB-900

Using Gels with the SB-900

The SB-900 has new technology that allows it to automatically detect the type of gel inserted into the flash head. Nikon does this by manufacturing the gels with built-in identification codes (figure 12.26). In order to fully use the new technology, you need one of Nikon’s newest professional-level cameras. Automatic gel detection and white balance control do not work on the D40, D60, D300, D2X, F6, and so on.

The idea with the new gels is to allow you to set your camera to automatic white balance and let the camera do the color correction for you. For example, if you are shooting in fluorescent light, you add the fluorescent gel to the flash. With the gel mounted, the camera and flash together determine the color temperature of the scene and automatically correct the color cast of the subject. The goal is to eliminate some of the confusion around color temperature and white balance.
