when processing the synchronized audio-video-slides openEyA
files. Duplicated photos,
or photos that have slighltly changed, are automatically discarded by openEyA
during the 'Processing

is that
all photos taken can also be easily straighten out (see section Photo Straightening/Reprocess
) and
synchronized to the corresponding audio-video recordings.
It is also possible to select the location of the openEyA
logo defult to appear
in the recordings (from the Photo Preview corners in Figs. 4 or 5). When photos are
straighten out, this logo can be cleaned out.
