Although
it can
seem a
bit
daunting
at
first,
the
exposure
triangle
simply
refers
to the
three
most
important
elements
of
exposure;
ISO,
aperture
and
shutter
speed.
When
you’re
shooting
in
manual
mode,
you’ll
need to
be able
to
balance
all
three of
these
things
in order
to get
sharp,
well-lit
photos.
ISO: ISO
controls
the
camera’s
sensitivity
to
light. A
low ISO
setting
means
the
camera
will be
less
sensitive
to
light,
while a
higher
ISO
means it
will be
more
sensitive
to
light.
An ISO
setting
of 100
to 200
is
usually
ideal
when
shooting
outdoors
during
the day,
but when
shooting
in low
light
situations,
such as
indoors
or at
night, a
higher
ISO of
400 to
800 or
higher
might be
necessary.
