Flash exposure lock Flash metering can underexpose or overexpose a photo in the same way that normal metering can. If someone’s wearing dark clothes and in front of a dark background, then the flash exposure may be automatically increased in order to brighten things up. This will cause skin to be overexposed. The same is true of bright or reflective backgrounds. The flash meter will reduce the flash exposure to prevent a picture being overexposed, but this means that people in the foreground will appear too dark in the photo. You can also use the flash exposure compensation function to correct this, or alternatively use your DSLR’s flash exposure lock button. This enables you to take a reading off the subject rather than the background, and lock that setting in for the next shot.
