I'm not really a camera person, and I have tried googling (not good at that either) can someone explain what an ISO is all about the numbers that go with it?
Evil-Penguin said:It is the film speed or sensitivity to light, i think typical values are 100, 200,400,800,1600,3200 and 6400. The higher the ISO number is the faster the film reacts with the light, and so you can get the same exposure with less light if you use ISO 1600 compared to ISO 100. This can be an advantage in low light situations or where you want a high shutter speed to freeze the action. The disadvantage to this however is that as it is more reactive to light, there is more noise picked up and images can often apear grainy whn using films with a higher ISO speed.
In digital cameras there is settings you can use to change the ISO speed, rather than having to change a roll of film in a camera.
Thats my understanding, I'm sure if i'm wrong or missed anything out someone else will correct me. Hope that helps
