SOME MODIFICATIONS IN AUTOMATIC PHOTOGRAPHY
If you wish intentionally to over- or under-expose
your picture for special effects or due to back-
ground conditions, you can realize your intention
even in automatic photography by over- or under-
rating the ASA setting on the camera.
Modification by this procedure may be desirable in
special circumstances as suggested below. Always
be careful to reset the ASA film speed to its
original value afterwards,
1. Against the light
When clear details should be particularly empha-
sized in your photograph, taken against the light or
a good deal of sky or sea water, simply set the ASA
to half the value of the original shooting from a
dark place, setting to over-expose by one F/stop
equivalent.
2. Against brightness shooting from a dark place
When taking a picture facing a bright subject, set
the ASA scale to double the original ASA setting
to under-expose by one F/stop equivalent.
