FEL (Flash Exposure Lock) Mode
With the world’s first spot metering for flash
photography using the principle of AE Lock, this mode
gives correct exposure even when the main subject is
not in the center of the viewfinder.
Before an exposure is made, a pre-flash is made by
1/20th power, the light reflected from the main subject is
spot-metered by the camera and the exposure level is
stored into memory (effective for 30 seconds). When the
actual exposure is taken, the flash output is determined
by this value.
It is possible to select any shooting mode of the T90 (Pro
gram AE, Shutter-Priority AE and Aperture-Priority AE
mode), for photographic effects.
