ISO (or Film Speed) in traditional photography refers to how sensitive film is to light

Take a photo using 100 ISO then take one at 6400 ISO
Because 6400 ISO is more sensitive to light the image will be over exposed
Try at different ISO settings – remember you’re not even touching aperture or shutter speeds
ISO is the easiest of the camera settings to learn – just set it and forget it:
If it’s a bright sunny day – use 100 ISO:
If it’s dark and dingy – use 1600 or 3200 ISO
If you’re not sure use 400 ISO
As you will be taking photos inside a building – where it will be dark – you should set your ISO to 1600+ before you start shooting
As you increase the ISO setting you also increase the amount of noise (or grain) your photo will have:
Before you start set your camera to 1600 ISO
Start in Shutter Priority mode and set to at least 1/60th
If necessary, wedge your camera against a wall when taking photos
Try to avoid using flash
