Hello,
Well, basically, the
flash has to provide enough light to lighten the shadows but less than the
highlights. So measure the highlights with a suitable meter to give an
aperture at the 60th second synch speed then use a flash meter to
measure the light in the shadows with the flash. Then use the 9 point
Ansel Adams scale to put the
shadow about 6 points darker than the highlights. That will ensure
detail in both the highlights at about 8 and the deepest shadow at about
2.
That can be expressed
at EV, but I?m unsure of the conversion, if I remember rightly, each of
Ansel?s points is one stop different from the next one and they range from 1
at the deepest shadow (with some detail) to 9 the brightest highlight which
retains detail.
I hope that makes
sense, I was taught by Dr Ingle, who is a well known local photographer,
however I?ve found it difficult to apply his methods to my digital
snapshots. He trained me on a 5x4 and a MF setup with a spotmeter.
He used a home made dial to convert the Ansel scale to EV.
Chris.

We are discussing using an on
camera flash unit, while photographing people outside. Here in the
desert we get very contrasty shadows on faces.

I'm having a difficult time
trying to explain fill flash to some members of a workshop I'm
facilitating. Could some of you please offer some suggestions as
to how to explain it so it can be easily understood.
The students understand the
concept - it's just difficult for me to explain the
mechanics.
I'd appreciate any help you
could offer.
