Selecting a flash mode
Your flash has three flash modes:
• TTL (auto-flash)—Your flash and camera work
together to calculate the correct exposure for the
subject and background. For more information, see
Using the TTL auto-flash mode
on page 13.
• Manual (M) mode—Lets you manually adjust your
flash output from 1/1 full power to 1/128th power in
one-third stop increments. For more information, see
Using the Manual flash mode
on page 16.
• Stroboscopic (Multi) mode—Lets you take a rapid
series of flashes to capture multiple images of a
moving subject in a single photograph. For more
information, see Using the Stroboscopic mode
on
page 18.
