6. Photography.
The camera and material have been described under outfit.
Lighting and preparation of objects is a main element of success.
When first looking over any ruins, make a list of every view wanted,
with the time of day when the sun will be right for it. Then follow
the time-table, and so get the best lighting all in one day.
For movable stones or figures place them in half-shade, as a doorway,
and then tilt every way until the best lighting is found, fix them in
that position, and then set up the camera square with them.
The camera should usually be fixed to look downward vertically, and
then variation up to 40 degrees can be got by the legs. Hold the
camera in the right position, keeping the legs off the ground, and
then drop the legs to find their own place; thus very skew positions
can be fixed quickly.
Small objects are best laid on black velvet, and taken vertically.
Scraps of charcoal are useful to prop them in exact positions. A
sheet of white paper stuck on a leg of the stand may be useful to
prevent shadows being too heavy. Where outline, and not flat detail,
is wanted, then a light ground is best; the most perfect is a sheet
of ground glass with white paper a foot or two below it.
