I sometimes have people who come on my training days ask what an exposure is
now some of you may think that's a very basic question which it is
however if you ever unsure of the basics it's worth asking.
there's a lot of misinformation and gossip spoken on forums and chat rooms
and occasionally in magazines the basics can sometimes be lost in the
technicalities.
an exposure is an amount of light needed against your camera sensor
in order to record an image whenever you press the shutter button
you're making an exposure what you're doing is opening a kind of two staged tap,
whereby light pushes up through the lens to splash against the sensor.
and an image is recorded, your cameras equipt with it's own built in light
meter
and for the most part it will manage the exposure for you and do a pretty good
job
on average tones, on average pictures, on average days but occasionally
you the photographer may need to step in and take control of your exposure
do something different for example i'm standing here in the shade
so Jayne has set the film camera with an exposure for me
in the shade. look behind me where the sun is shining in the bright patches
it's completely overexposed it's burnt out
if I went and stood in the Sunny bit without Jane changing the exposure
I'd be burnt out to so there is a choice to be made
there's also another choice to be made for creative purposes.
yes good
Ah that looks fine. The correct exposure time is what ever you want it to be.
for example I'm standing in here and it's a bit darker than it is out there
if Jane wanted to she could expose for out there.
And i'll go dark, and then back again so the correct exposure in this case
is for in here for me. So if i
want to take a couple of shots of Lorna, happy pictures tend to be brighter pictures,
so I could up the exposure just subtly a bit to try and get that
happy sunshine feel into a picture, aw.
right it's really great, turn your face that way just a little,
only a bit, there we go. Aw look, excellent.
fantastic happy Lorna.
now if we want to do moody Lorna
we could turn that down a bit I'm gonna shoot her at minus a third of a shot
just to give it that moody edge so,
for this one that's it, just put your chin
down slightly. turn your chin, down a little more.
Excellent, that's it. The famous Lorna gives a stare.
We've got this lovely moody looking kind of a shot there. So there is no correct there is
exposure,
the exposure is where you want to put it, it's up to you, photographer
to just move it around to the place that you find pleasing
