let's take a look at it incidents meter reading and see what that's all about,
to take an incident meter reading you're gonna need one of these
it's a hand held light meter, my photography used to live or die
by these in the days of film because of course I couldn't have a look to see what my shot
looked like.
the way it works is this little
white cone here it's called an invercone
the place
and inside behind a there is a little reflective
light sensor here and that measures
how bright the inside this little Coneys I could use that's too reflected reading
if I wanted but pointy it
things but was very much point because she camera do it far more effectively
first thing you do when you got a hand-held light meter we switch it on
and you I think you can say but then here in the bottom corner
there's a little window this is ISRO that's the same as the ISO in your
camera
seamus make sure that the I say on your camera
is exactly the same as the I say when you meet a
okay in fact I said on the Mater site look at the camera so I say you're using
set it on your light meter because if they're different its gonna give you the
wrong exposure because they like me to work now
how sensitive the sensor on your camera is next what we do
is we hold the light meter in front of our subject
like this we point the white kind back to the camera
in so you've got the camera on a pointed at you all I have to do is press the
little
trigger button on the side that comes up with an exposure
I don't know if you can see this what it's saying is a $500 to the second
at F-four point seven so ignore the 0.7 the site 3 laotian why but these are
super Acura
so there we go and they don't have to do is to get my camera
pick it up manually set a 500 for the second
F 4.7 500 for the second
and i cant get F for his work and a 4.5 is really really close
so that should be the correct exposure and I can line up shot and I can take a
picture let's try on the grill
her and indeed we have a nice
black dark frame here I don't know if you can see if not we'll
but the picture it suppose you want to use a 4.7 you wanted more depth of field
say what is a smaller aperture
well all you have to do it is these little up and down buttons
on the side here what that will do is it will change
you aperture so I've gone from 4.7
25.6 in the shutter speed when I do it goes from the five hundredth
two or three fiftieth so you can still choose which aperture you want to use
field at the field in your creativity if you wanted to use
F-sixteen kiss you gonna shoot something you want lots at the the failed
you just set it here and it gives you the shutter speed then you can pop it on
to your camera
so that the light meter reading from
groom 125th the FIA if we go over to the bride
it's still a 120 for the FAA
is changed by point n neva stop the sings a very sensitive
same exposure re both bride and groom because the same like is falling on them
as one big obvious drawback with these things suppose you're on the hard even
life time you going to the poll
he hiked up through the Sibel town to Namche Bazaar
and you looking across to mount everest which is probably about 25-30 miles away
you wanna take a light meter reading from Mount Everest in the sunrise
you know that again hi 25 or 30 miles through the through the Himalayas to
take a rating and even if you did by the time you got back the light would have
changed wouldn't it
bit pointless really that is where the reflective me to rating if your camera
really comes into its own because you can free up the shot
and the camera will tell you what it thinks now suppose he is a bit of a
dollar overcast day with a white Scion is lotsa snow everywhere
you now know that that is going to trick the camera
into making the exposure to dark so all you have to do
mister over expose it a bit set it so you like me to says that's a bit too
bright and then we'll probably be about right
because you can take test shots its digital it doesn't matter you can just
take a shot going to be darkness a bit raw it was a bit too bright there we go
now we know what we want to do
and it's the same the other way around if you want to shoot something at night
you doing night photography
the cameras gonna try and brought it up because it's a dark subject
so you need to tell it to underexposed you can do this manually
at the same with over exposing by the way to do it manually
just as I did we could use the exposure compensation but if you don't want
talking about
take the exposure compensation link below the film equally
these things a brilliant for doing what we've just done port rights close-ups
macros products things like that you can get a perfect exposure every time with
one click setting on the camera where you go
brilliant if the light is in changing the look pretty constant today
because the day when the sun's going out you gotta keep re metering
so they go two different ways to Mater me the one is right neither one is wrong
it's just about knowing how to use them
