ISO+1

=ISO ﻿ = Film Speed

A original ISO setting was showing how sensitive the film is to light.

When i am trying to get the perfect picture i ask myself these questions;


 * "Light**– Is the subject well lit?
 * Grain**– Do I want a grainy shot or one without noise?
 * Tripod**– Am I using a tripod?
 * Moving** Subject – Is my subject moving or stationary?"

It is often measured in numbers like this;



In Digital Photography shows the sensitivity of the image sensor. This same thing applys to film photography. the higher the number the more sensitive the camra is to light. Higher ISO is generally used in darker situations to get faster shutter speed.

Other circumstances when you might have to use ISO to get a higher setting;


 * **"Indoor Sports Events**– where your subject is moving fast yet you may have limited light available.
 * **Concerts**– also low in light and often ‘no-flash’ zones
 * **Art Galleries, Churches**etc- many galleries have rules against using a flash and of course being indoors are not well lit.
 * **Birthday Parties** – blowing out the candles in a dark room can give you a nice moody shot which would be ruined by a bright flash. Increasing the ISO can help capture the scene."


 * ISO** is a very substantial feature in digital photography so that you have control over the settings of your digital camra.
