Photography is a complicated process. It can be broken down into three pillars: exposure, shutter speed, and aperture. To take great pictures you need to know all the different factors that affect your camera’s settings as well as how they interact with one another in order get just what you want!
What is ISO in Photography?
The sensitivity of the medium determines how much light is needed. This has been true for glass plates and film, as well as digital sensors today. Earlier on this was expressed in different ways including ASA (American Standards Association) which used to represent a specific number that would be multiplied by another factor related to time or distance depending on where it applied such as 4×4=16ASA(in feet). Now ISO refers more specifically to cameras than anything else with an international standard meaning “International Organization for Standardization.” It started out at 100 but now can go up from there based upon the environment they are being used in etc.(500ISO – outdoors, 160-200ISO indoors.)
ISO in film photography
In film photography, ISO is an indication of how sensitive a film is to light.
The lower the number in your camera settings (100-800), the more light it will take in and therefor you’ll have finer grain on photos that are taken as well.
Common ISO Values
The ISO of a camera is the most crucial aspect to getting clear shots in any circumstance, and there are many different ranges that you can use. A common set would be as follows:
ISO 100 (low ISO)
ISO 6400 (high ISO)
Shooting a photo at ISO 400 will make it twice as bright, while doubling your exposure time. In contrast to shooting on an automatic setting with the same light … Read the rest
