E-TTL II/E-TTL
This is an advanced autoflash metering system
developed by Canon. This feature controls flash
output using metering results obtained from
taking ambient light and pre-flash light before
shooting into consideration. E-TTL II uses the
same EOS multi-segmentation metering sensor
that meters ambient light for autoflash metering,
and in addition to lens distance information and
AF point location information, carries out high-
precision flash compensation.
FEB
This stands for Flash Exposure Bracketing, which
allows three separaate exposures while changing
the flash output (up to ± 3 stops apart).
Guide Number
This is an index that shows the brightness of the
flash. The higher the guide number, the greater
the flash output, and the further the flash will
illuminate subjects more brightly.
Flash exposure compensation
This adjusts the flash output amount. This allows
you to intentionally lighten or darken automatic
flash output.
Flash synchronization speed
This is the upper limit of the shutter speed
that can be set on the camera for normal flash
photography. With most EOS cameras, it's 1/200
sec. or 1/250 sec.
Fill flash
Blending flash illumination with ambient light in
a scene. It can be anything from bright sunlight
ourdoors, to indoor lighting. This is useful for
situations where the subjects face becomes dark
(or the background is overexposed). Simply
illuminate the subject with a fill flash when
shooting for the proper brightness on both the
subjects face and the background. In Av or Tv
modes, balanced fill flash occurs automatically,
even in dimly-lit conditions.
High-speed sync
This mode allows shooting at a faster shutter
speed than the normal max. sync speed, but
flash power drops as shutter speeds rise.
