Old and new. A English 'Ensign' faces a modern Epson digital camera.
|
|
The Epson is newer but is it better? The Ensign uses roll film giving
6cm square negatives and hence a massive resolution which easily out
permorms the 1-2 million pixels of the Epson. However; it takes two
seconds to take a picture with the digital camera while the Ensign
demands two minutes after a lot of practice.

35mm SLRs are the modern choice for most ethusiastic photographers.
Left is a 1970s Olympus OM, right is a 1990s Canon EOS. Both in
their day were considered 'entry level' SLRs. The OM has semi
automatic exposure, everything else is manual. The EOS is auto
every thing; truely point and shoot.

SLR stands for Single Lens Reflex. The camera has just one lens as
opposed to the two in the cameras above: the taking lens and the
viewfinder lens. In a SLR the photographer looks through the taking
lens via a prism and mirror. The mirror "reflexes" out of the way
when the shutter is fired to let the lens' image reach the film.

One of the last cameras made by the English company MPP. This is a
"technical" camera. The lens is by the German company Schneider.
Together they produce negatives that measure five by four inches in
size. Five-Fours are the smallest of the "large format" cameras.

There are several designs for large format cameras. A technical
camera combines portability (it can be folded into its case) with the
ability to; tilt the back, the lens or to slide the lens up-down or
side to side. These movements allow the photographer to manipulate
the image in ways not possible with most 35mm or other "rigid"
cameras. For example; tilting a camera upward to photograph a tall
building creates converging verticals - the building seems to lean
in on itself. By moving the lens converging verticals can
be eliminated and the building looks its proper shape.
