Vihan,
The first low (&no) budget short film event in Iran,
Presents.
In association with
Khanesh institute
and 35mm studio
Natural Lighting Cinematography
Chapter 8
Studying an Example
Let's assume these two are from a single identical camera
and the difference between their contrast
is not because of the camera
the high light in there
and the high dark in here
actually
are not matched with each other
Guys, please look at the front of yours
See, now,
proportion of light on the faces is fairly the same
to some extent
but
due to this high light
these two shots are not matchable
if we cut them together, the over-lighted area will be bothering
if they cut to each other
we have a one third darkness suddenly to one third lightness
we can hide the over lighted area with our foreground sujet
now, the over light area is much less than before
and the proportion of lightness and darkness is mostly balanced
except for their cloths
We can make it right, in post-production
However, I can do this
without reducing light off the right-hand sujet
reducing the light off the white sweater
See?
to make a right ratio
a right cut
Another part of the frame which is different from the other one
 
is the lightness in this place
would you please move a little bit?
 
 
You see there is a light here that is not on right sujet
I can lighten it to have contrast ratio of faces.
this much is OK
now the contrast ratio of the faces is almost equal
 
[reducing 1-stop of diaphragm]
the left frame is still lighter
I lighten the right sujet a little more
although it turns to left sujet's face as well
Can you notice?
A part of it is also because of the contrast of the cameras itself
but if I don’t want my left sujet to be lightened
I can turn my reflector just toward the sujet I want
this if for both cameras rolling at the same time
if we use one camera
we won’t have this kind of problems
when you use two cameras at the same time it gets more complicated
but let me test that again
clothes of the left sujet
there’s another layer in here
as you can see
 
It’s a diffuser
you can see my hand though it
It’s for you to soften sharp and direct light
removing sharp shadows
now I can darken left sujet's clothes
up to this level
right?
to have same ratios of darkness and light in two frames
there are some times  you want to have this difference on purpose
like you want to say this person is white and the other is dark
in that case it’s ok for that to happen
sometimes it’s good to make this purpose happen using background
like we want to say this sujet is a good person
for that you can have him in light with dark background
and the other person be vice versa
dark himself with light background
which is the same thing that happened here
light background with dark clothes
and dark background with white clothes
as I said cutting these two frames together will create a fine maintaining
Unless he wears dark clothes
in that case things will be different
now someone with dark clothes, please sit there for us, to see the difference
now how do you feel about these two frames
what's the difference?
too similar
but the backgrounds are different
now we feel like one of the frames is quite lighter
just because of the backgrounds being different
the rest seems the same
this door here is lighter
we may close the door a little bit to make background darker
now if I open it I’m going to have a lighter background
it still would not be a nice cut
Even if for that little bit
when it’s inevitable to record without adjusting
we darken here later in post-production
in color-grading step
When we are working with two cameras
we can make them similar later
sometimes, the same camera results in different outcomes
in different times of the day considering day-light changes
sun might be out, or It’s not snowing anymore or whatever
in that case those two frames will be different
so we try to make them close to each other in post production
_ look at each other _
now with this reflector I give them both a fill light
now this film can not be known as a low key lighting
because faces are all kind of light
Of course their clothes are dark
but if you want to have a high key lightning
you should be able to change these clothes as well
faces are low high key lightning
and now low key lighting
_ look at each other _
sure, a light is necessary in the back of right sujet
you may need a light like this from right sujet's back
maybe we need two reflectors
I also want to make a rim light
I think it's not possible here
move left a little bit
enough
it would not happen
but we may be able to have it from right side
still because it’s white it really would not create well
now I make it with the gold
yes , sort of
now you see right side of right sujet's face is getting lighter
we really didn’t use any equipment
just day-light coming from the gate
and a reflector
it seems like there are too many lighting stuff here
yet, it's a good picture
now
if we want to have a master shot
we choose a side
it depends on what your movie
your lightning mood is high key or low key
we test the both to see the difference
check this frame now
the background is clearly over-exposed
it’s not what we want
we can close the diaphragm
you see it’s not that bad
it’s fine up to here
if we want to correctly expose we would have this
but sujets are too dark now
this frame
is not matchable
with our previously frames with single sujet
