10 Interesting Facts on Photography

10 Interesting Facts on Photography
  1. The first flashes were mini- explosions of a mix of potassium chloride and aluminum. Unfortunately, when you mix potassium chloride and aluminum incorrectly, you get a huge explosion.
  2. A camera lens is circular, but the images appear as the square. This is because, camera lenses are a part of optical system, whereas the image formation totally depends on the imaging system. The light must be bent more to reach the edges of the circular image.  The rectangular sensor crops out the outer edges of the circular image from the lens for the best image possible.
  3. The camera that took the first photos of the moon surface is still there. The cameras that captured the first frames from the moon in 1969 was a Hasselblad Data Camera (HDC) with a Zeiss Biogon 60mm f/5.6 lens and a 70mm film magazine, and a Hasselblad Electric Camera (HEC) with a Zeiss Planar 80mm f/2.8 lens. The weight requirements to successfully return to earth were very strict so the astronauts had to remove the film magazines from the cameras and left the cameras and the lenses behind.

  4. The first photography paper was made out in a black liquid form which was light-sensitive.
  5. Have you ever wonder what is the f-number of the human eye? Our human eye has an f-stop of f/8.3 in a bright environment and f/2.1 in the dark environment.Here’s what Wikipedia has to say:

    Computing the f-number of the human eye involves computing the physical aperture and focal length of the eye. The pupil can be as large as 6–7 mm wide open, which translates into the maximum physical aperture.

    F-Number of the Human Eye?

    The f-number of the human eye varies from about f/8.3 in a very brightly lit place to about f/2.1 in the dark. The presented maximum f-number has been questioned, as it seems to only match the focal length that assumes outgoing light rays. According to the incoming rays of light (what we actually see), the focal length of the eye is a bit longer, resulting in minimum f-number of f/3.2

  6. The first digital camera was of 8 pounds with 0.01 megapixel and it took 23 seconds to capture one picture.

  7. Nobody Ever Smiled in Old Photos Because They Were Using Back Braces. Forget the well-known photography facts about 1800s portraits you thought you knew. While it’s true that nobody ever smiled in old photos because the exposures were so long, they also weren’t smiling because they were using back braces to stay perfectly still.

  8. The interesting fact about photography today is, it has introduced 80 different types of photography and 10 different genres says Wikipedia
  9. Photoshop was created by the Knoll brothers in 1987 as ImagePro. It was bought by Adobe to create what we now know as Photoshop. Later Photoshop 1.0 was released on 19 February 1990 exclusively for Macintosh only.
  10. Photography is an art, it has some technical types too: JPEG, the most common compression format for digital images, that stands for Joint Photographic Experts Group.

So now we have some amazing facts on photography, let’s go out and explore ourselves to be a great photographer. Today the world is introduced by a Mirrorless camera, the journey from photo camera on papers has traveled till a Mirrorless High-End Digital Cameras.
