Due to the changing nature of online business, the Cameras
and optics articles are no longer
the company website, and the camerasunderwater.info domain has been
redirected to the main website (.co.uk). To avoid the
disappearance of the information from public view, the articles have
moved here. The associated content was
me (David Knight), and in that case, the copyright reverts to 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
for a replacement heart-valve, and ceased to carry out maintenance work
or add new information to the company websites at that point.
This 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 huge amount of work
on my part, and while the available equipment might have changed, the
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out-of-date are nevertheless of general and historical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
rescued them, edited them to get rid of anything totally useless or
incorrect, updated them in some places, and
given them a new home.
