Ultimate digital vs film: 1gp digital vs SR71 reconnaissance cameras

The film used in the SR71 looks like a large format roll film. Plus the
huge diameter lens is truly impressive looking. There must be a good
reason for wanting lots of film area when resolution is of prime importance.

Actually there were lots of cameras aboard. They ranged from 35mm to 9.5
inches. The main camera was the 5 inch film size scan or OBC. The side
looking TOC's were 9.5 inch units.

Actually the whole system really didn't work all that well in a true
operational mode. Although the plane sure looked great.

Don't forget the advantages of having those optics in a vacuum and the path
from subject to optic is influenced by an ever decreasing proportion of
atmospheric interference.

Actually the vacuum caused more problems then in air. One of the big problems
is outgasing. Sort of like eating too many bakebeans.

Didn't it have the biggest radar signature ever seen?
A bit like the opposite of stealth, but too fast to catch anyway.

Take those declassified documents with a grain of salt.

I saw declassified satellite images around 1960 where you could
read the logo on the side of a truck. [...]

Mind if I Laugh Out Loud? If they (whomever 'they' are) said those
were
satellite images, then it was pure misinformation and served its
purpose in
that regard: you were fooled, and it may have frightened the Soviets
into
further spending themselves to oblivion.


I believe him. Have you ever heard of teraserver? It is a satelite
available to the public which can basically see your backyard. If such
tech is available to regular citizens now, dont you think the military
has at least that back then? I wouldn't be surprised if the military
can get your shirt size from satelites now.
