The basic rule is: "For astronomical photos of the Moon's surface, set aperture to f /11 and shutter speed to the [reciprocal of the] ISO film speed [or ISO setting]." [1] With ISO 100, the photographer should set the shutter speed to 1/100 or 1/125 second. (On some cameras, 1/125 second is the available setting nearest to 1/100 second.)
Extreme or ultra-wide-angle lens - a wide-angle lens with an angle of view above 90 degrees. [4] Extreme-wide-angle lenses share the same issues as ordinary wide-angle lenses but the focal length of such lenses may be so short that there is insufficient physical space in front of the film or sensor plane to construct a lens.
Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.
Armstrong was also tasked with taking lots of pictures during the mission. That's why almost every NASA Apollo 11 photo you see of an astronaut on the moon actually shows Aldrin, and not Armstrong.
In photography, backscatter (also called near-camera reflection [1]) is an optical phenomenon resulting in typically circular artifacts on an image, due to the camera's flash being reflected from unfocused motes of dust, water droplets, or other particles in the air or water.
A central shutter is not a type of shutter as such, but describes the position of the shutter: it is typically a leaf shutter (or simple leaf shutter), and located within the lens assembly where a relatively small opening allows light to cover the entire image. Leaf shutters can also be located behind, but near, the lens, allowing lens ...
The design of the leaf shutter limits almost all TLRs to a maximum shutter speed between 1/100 and 1/500 of a second. Certain photographic filters are inconvenient without line of sight through the taking lens – notably, graduated neutral density filters are hard to use with a TLR, as there is no easy way to position the filter accurately.
One such conspiracy theorist took to YouTube recently to show what he calls “proof” that the Apollo 17 landing was faked. ... Where's the reflection of the camera taking the photo?” and the ...
