the man to brief me on it, and I since have read up a little bit further
on this exposure meter and there is a little soft, white cap
that goes over the eye of the exposure meter which takes diffused

~hen takes an average of all the light it sees o
Now when I was
~
using it, I didn °t have this cap on there and I then got the
brightest light of some area and that ' s why we overexposed
the fil m
Nordberg ~ Yes, yes oo o it's very simple ooo
Schirra - It 0 s as basic as that , and that ' s why I over -exposed
these light values that I came back with and which were recorded
are really of no great value because of this, I think.
I t's a
small focus - the exposure meter is just about that size cubed
(demonstrating) it 0 s a beautiful little piece of equipment and
quite accurate o
We had a calibrator, but it should have been
(capped) ooo Gordon Cooper knows this and will have a cap on his ,
I might add o
Nordberg - Have all pictures been overexposed?
Schirra = No, I looked out on occasion where I would be looking at
an almost uniformly lighted area such as the surface of the earth o
When I had the horizon in the picture, we usually overexposed
because I had two different light levelso
Dunkelman - Well, the pity of it all is, since you do need an
exposure meter to get a good picture, and exposure meters give you
a number, it's too bad the numbers isn ' t available.
Schirra - I did record these .
Dunkelman - Sooner or later these numbers are going to give you a
