The
Underwater
Photography Info articles
Due to the changing nature of online business, the photography
and optics articles I wrote some years ago are no longer hosted on the
Cameras Underwater website. To avoid the
complete
disappearance of the information from public view, the articles have
been
moved here. The associated content was
mostly produced
by
me (David Knight), and in that case, the copyright remains with me; so
please
contact me
if you are looking for permissions.
One reason for moving the articles is that they are no longer
up-to-date. I had to retire in 2011, due to the
need
for a replacement heart-valve, and ceased to carry out maintenance work
or add new information to the company websites at that point.
That created a problem with regard to the info articles,
for which the easiest solution would have been that they should simply
vanish. They do however, represent a large amount of work
on my part, and while the available equipment might have changed, the
laws of
physics haven't. Also, some of the articles that have become
out-of-date are nevertheless of general and historical
interest. I was therefore reluctant to let them die; so I
have
rescued them, edited them to get rid of anything totally useless or
incorrect, updated them in some places, and
given them a new home.
