Technique Photography Policy Imaging should be understood as a
fundamental technology for the production of a good
picture , good
contrast of the image (
focus) and light (
exposure) on the right.
Package of measures aimed at the contrast of the object, the focus ring on the lens to the
viewfinder, it is obvious that the original object was so clear (in focus), the rotation of the object image is performed in order to concentrate on the line / crisp and clear and firm (not blurred), said interest in the ring at a distance. (In meters or feet) to the lens of the company in June, will be displayed.
Most importantly, the image that should be considered in the
light beam process of creating a
film camera. In this case, the light so that objects can be captured in the film should be enough light, the process () and something the size of the aperture, shutter speed and film speed (ISO), to include these three things determine the success of the in the film as a rule requires an object with a
light film to light. (
Over exposure) or (under
exposure). (Sub) absence.
The size of
aperture / f pointed out, 2, 2.8, 4, 5.6, 8, 11, 16, 22, and 1.4: These figures are
based on the lens. Aperture / f is 1.4 or f/22, these figures show the size of the aperture of the lens.
Aperture to determine the intensity of light that will be used.Aperture inversely proportional relationship between the numbers.
"The number / fax with a small hole to light through a small lens, low contrast / aperture F, so that the light is much broader than the contribution."
- Excerpts. (Shutter speed).
Shutter speed is fast or slow shutter open and then close back to work.
Exposure control is easier to film in the long run. It works like a shutter, window shutter, the shutter opening and closing the alias to access cinema and to the light that shines.
, 2, 4, 8, 15, 30, 60, 125, 250, 500, 1,000, 2,000, and B: 1, one
exposure is calculated by reference to a number of bolt / 1 turn at a speed of 1. secondly, 2000, № 1 / 2000 second
shutter opening and B (bulb) refers to the speed and so on (shutter open until the shutter release is pressed).The relationship between the number of opening the shutter speed is directly proportional to the coating.
"The more money to open the shutter speed up and put it in low light at slow shutter opening and closing, which means more light .."
- The film sensitivity (ISO)
Smaller ones more film (lower ISO),
the film is less sensitive to light up more and more light is needed to illuminate the film, but the higher the ISO the more
light-sensitive film up a bit more light required to illuminate the film. For example, ASA 100 requires more light than ASA 400.
