optical diff
/vee'dif/ Visual diff. The operation of finding differences
between two files by eyeball search. The term "optical
diff" has also been reported, and is sometimes more
specifically used for the act of superimposing two nearly
identical printouts on one another and holding them up to a
light to spot differences. Though this method is poor for
detecting omissions in the "rear" file, it can also be used
with printouts of graphics, a claim few if any diff programs
can make. See diff.

/vee'dif/, v.,n.
Visual diff. The operation of finding differences between two files by {
eyeball search}. The term optical diff has also been reported, and is
sometimes more specifically used for the act of superimposing two nearly
identical printouts on one another and holding them up to a light to spot
differences. Though this method is poor for detecting omissions in the
‘rear’ file, it can also be used with printouts of graphics, a claim few if
any diff programs can make. See diff.
An interesting variant of the vdiff technique usable by anyone who has
sufficient control over the parallax of their eyeballs (e.g. those who can
easily view random-dot stereograms), is to hold up two paper printouts and
go cross-eyed to superimpose them. This invokes deep, fast, built-in image
comparison wetware (the same machinery responsible for depth perception)
and differences stand out almost immediately. This technique is good for
finding edits in graphical images, or for comparing an image with a
compressed version to spot artifacts.
