The built-in flash in the FinePix S1 Pro covers the field of view for a 28 mm
lens and has a guide number of 15 (ISO 100
•
m). The flash also features TTL-
BL flash control that uses brightness information obtained using multi-pattern
exposure metering to effectively control and balance the amount of flash so
that both the main subject and the background are correctly exposed. This
allows you to take natural looking pictures using the flash (when a Nikkor lens
with built-in CPU is used). As well as in low-light conditions, you can use the
flash as a supplementary light source to reduce shadowing on your main
subject in outdoor shots taken in daylight or when you want to add catch lights
to your subject’s eyes.
The FinePix S1 Pro also provides 4 synchro modes: Normal synchro, red-eye
reduction, slow synchro and red-eye reduction slow synchro.
• When the lens used is not a Nikkor lens with built-in CPU, TTL flash control
is used in which allowance is not made for exposing the background.
(Wherever possible, use a Nikkor lens with a built-in CPU.)
The flash control range (effective flash range) varies depending on the
selected ISO sensitivity and aperture settings. Refer to the table below for the
flash control range details when the built-in flash is used.

• If you are shooting at distances as close as 1 meter, select the aperture-
priority exposure mode (“A”) and use an f-stop of number of at least 8.
• When the sensitivity is set to ISO 800 or ISO 1600, the built-in flash will fire
but flash control may not be performed correctly.
Shoot in preview mode so that you can check the exposure.
