ISO Settings | RED TECH Video Lecture | Camera: Its Basics and functioning (Educational Series) - Photography

hey everyone I'm clay and today we're
going to be talking about ISO now the
first thing to remember is in the red
eco system
ISO is just a metadata adjustment so
it's not baked in you can always go back
and fine-tune it but just because it's
not affecting your raw image doesn't
mean you shouldn't have to think about
it put simply ISO is a value
representing your capture medium
sensitivity to light one of the
questions I hear a lot go something like
this
what's your camera's native ISO which
actually isn't such a simple question
answer because here at red we're not
limited to a sweet spot of ISO
performance but rather a range between
around four hundred and two thousand ISO
the reason for this is we treat ISO more
like a lookup table but even that isn't
completely accurate because it uses
floating point notation so we coined the
term flood what this means is that the
choice of ISO actually affects the
interpretation of the perceived mid
point in the value range and not the
value range itself that seems a bit
complicated it's because it is but the
truth is all you need to know about ISO
the function is the same way it has on
every other camera you use your outside
on a sunny day and you drag your ISO
down you'll see the visible light cut if
you're inside in a low light condition
and drag that ISO up you're going to see
a raise in the value of white so the
truth is that lighting and aperture are
your real key players another question I
get all the time is what is flood and
why would I adjust it now an easy way to
think about how flood and ISO relate to
each other is to think of ISO as the
hour hand of a clock while flood acts as
the minute hand meaning that the ISO
adjusts in large predetermined chunks
such as 200 400 etc and the flood or the
minute hand is adjusting in smaller
increments to really dial in a look say
for video village with our best-in-class
dynamic range ISO flood and other
metadata adjustments you can really set
a good baseline look for your project
while still preserving the flexibility
to push it around in post meaning that
if that window is just a little bit too
bright we got you if that corner doesn't
have quite enough detail you can fix it
which is great if you're a perfectionist
like me too
