ISO is the third element of exposure

Posted by Mike Voss on Tuesday, May 14, 2013, In : improving your photography 
A long time ago I talked about three things involved in manual exposure. They are your aperture, shutter
speed and ISO, which stands for International Organization for Standardization. Trust me, I am not making this up.
Once upon a time film was sold (actually it still is) in varying speeds. For example you could buy 100, 200
or 400 speed film.
In digital photography ISO is the measurement of the sensitivity of the image sensor in your
camera instead of the film. The higher the ISO the less li...

Shutter speed with your aperture

Like your aperture, the shutter speed you set on your camera also controls the amount of light

To continue with the metaphor of the room and the window, if you leave the curtains open for an hour you allow more light (cumulatively) into the room than if you leave them open for half an hour. That’s how your camera’s
shutter speed works ...

There are three elements to photographic exposure. They are often referred to as a triangle, and the the three points of
the triangle are aperture, shutter speed and ISO. These three elements are interconn...

What is ISO speed and why should you care?

Posted by Mike Voss on Wednesday, February 8, 2012, In : improving your photography 

If you want to take your photography to the next level you’ll need to learn
what some of your camera’s manual settings mean, and how to make them
work for you. ISO is a good place to start.

ISO stands for International Standardization Organization and their film
speed ratings are used to indicate the amount of light necessary for a proper
photo exposure. A film, or digital media, rated at ISO 200 requires half as much
light as digital media rated at 100.

This means you can take a...
