ISO BRACKETING
As an alternative to conventional automatic exposure bracketing (see section 2.3.2), you can use ISO exposure bracketing. When using this function, the camera creates three differently exposed images, and the largest exposure variance between each image is ±1 EV. In contrast to the regular exposure bracketing, however, the three images are created not with different combinations of aperture and shutter speed, but with sensor signal amplifications of varying degrees—or, in other words, different ISO settings. The camera doesn’t need to take three different exposures in short succession when executing this type of exposure bracketing. The sensor data from a single exposure will suffice; the camera develops the same data into three ...
