In most instances it is best if you stand perpendicular to
the object being photographed.
You can use the white pages of a notebook to refl ect light
into the shadowed portions of exposures, especially under
overhangs.
Include a scale or make a note of the size of the area being
photographed. Depending on the subject of the photograph
this could be anything from another person to a ruler,
camera lens cap, coin or penknife. For small-scale
photographs a fi nger is also useful and one of the
advantages of this is that you will not inadvertently leave it
behind! Ideally with medium and small objects use a metric
scale rather than an object such as a lens cap or coin
because these have variable dimensions. In addition the
scale should preferably be of a neutral colour (grey) so that
it will not unduly affect photographic exposure.
Alternatively draw a scale on the cover of your notebook
with a bold marker pen.

Remember to include a scale
in every photograph and
ensure that it is appropriate.
A badly chosen scale or one
that is not against the rock
face can produce confusing
results.
When taking a photograph of an area you have sketched
consider including the fi eld notebook page in one corner of
one of the photographs as a means of cross referencing
between the photographs and your fi eld notebook
(assuming the fi eld of view is appropriate).
Use a page of your fi eld notebook to point out or label
particular features (e.g. Figure 7.15) on the photograph.
Assuming you are using a digital camera check, using the
camera display screen, the exposure and as far as possible
that the focus is OK before you leave the locality so that
you can take another photograph if necessary.
