Flash compensation/
output
The options available vary with fl ash control mode.
•
TTL : Adjust fl ash compensation (the full value may not be
applied if the limits of the fl ash control system are exceed-
ed). In the cases of the EF-X20, EF-20, and EF-42, the select-
ed value is added to the value selected with the fl ash unit.
•
M/MULTI : Adjust fl ash output (compatible units only).
Choose from values expressed as fractions of full power,
from ⁄ (mode
M ) or ¼ ( MULTI ) down to ⁄ in increments
equivalent to ⁄ EV. The desired results may not be achieved
at low values if they exceed the limits of the fl ash control
system; take a test shot and check the results.
C
Flash mode (TTL)
Choose a fl ash mode for TTL fl ash control. The options avail-
able vary with the shooting mode (
P , S , A , or M ) selected.
•
E (FLASH AUTO) : The fl ash fi res only as required; fl ash lev-
el is adjusted according to subject brightness. A p icon
displayed when the shutter button is pressed halfway indi-
cates that the fl ash will fi re when the photo is taken.
•
F (STANDARD) : The fl ash fi res with every shot if possible;
fl ash level is adjusted according to subject brightness. The
fl ash will not fi re if not fully charged when the shutter is
released.
•

(SLOW SYNC.) : Combine the fl ash with slow shutter
speeds when photographing portrait subjects against a
backdrop of night scenery. The fl ash will not fi re if not fully
