  • What is ISO?

    Posted on May 28th, 2012 Staff Writer

    Throughout many articles you have read along with the experience you have reached, there has been many mentions of ISO and your digital camera.  So what is ISO and how does it relate to your digital camera.  ISO is your cameras sensitivity to light measurement.  In other words the higher the ISO number is, the more sensitive the sensor.

    For example, if you are capturing an image with minimal lighting it is best to have a high ISO setting.  Your digital camera’s ISO setting determines the sensitivity to light that your sensor has.  Therefore, having a high ISO in low light environments means the more light that will be captured in your photograph.

    It is best before capturing a photograph to experiment with different light settings and your ISO setting.  Many photographs taken with minimal light don’t capture the essences of the photograph.  This could be in part to a poor ISO setting.  There is nothing wrong with experimenting and finding the optimal ISO setting for your environment.

    Most manufactures like to raise the ISO setting of a camera far more than what is advertised, so the best thing to do if you want high quality photographs in low lighting is to research your camera or buy a DSLR.   But, the most effective way to find the ISO setting right for you is to experiment with the camera and environment.
