Taking photographs for photogrammetry can
be a complicated process. As long as you keep
the following fundamental ideas in mind, your
work will benefit:
• Decide first how to deal with specimens that
you need to move to photograph
completely: either aim to have the
alignment performed only on the features
found on the specimen blank the
background, or use a highly structured
background useful for alignment add
markers on the specimen so you can align
partial models easily.
• If re-shooting a specimen later will be
difficult or costly, always add a structured
background and markers.
• Add a scaling object (scale bar, markers with
known distance on object, etc.).
• Take in focus, well-lit photographs with as
high-quality a camera as you can get.
• Cover all the surface of your specimen with
much overlap between photographs.
• Mask thoroughly (if appropriate for your
alignment and model building method).
