ISO isn't effected by zooming but the aperture is. The more you zoom in or the longer the focal length: the less the aperture can open and that's why you are getting darker pictures when you zoom in. After you zoom you have to re-evaluate your exposure.

The lecture was great but I wanted to know if zooming has any thing to do with ISO because whenever I zoom the picture appears darker.

I have had my Nikon D80 for 2 years and don’t know how to use it properly. I have now learned about ISO. Will practice tomorrow at day light. Any tip on how to get great pictures with the Nikon D80 will be appreciated. I love photography. Thanks to all who reply.

Its really simple and superb. I will start my photography from today onwards with my Canon PowerShot A590 IS.
