Sometimes people forget or do not consider what effects exposure can have on the final result of their shot. Exposure has three major components, ISO, aperture and shutter speed. All three of these exposure components have an effect on the final sharpness of your image.

I have been taking photos at concerts I have been to over the last 4 or 5 years and normally come away with a few keepers but I have always been left a little frustrated that due to camera restrictions, I could only take in my point and shoot. A few months ago I put my name down as a contributer for an online magazine so I could start building my portfolio and confidence as a live shooter. There is no pay for this but it's a great time and I am getting to see bands I'd never see.

So, what have I learnt so far? read on....

What is ISO

ISO traditionally referred to the films sensitivity to light in number increments typically 80, 100, 200, 400 800 as depicted on the film cartridge image. The lower the ISO number equated to a lower sensitivity to light (also known as a slower film) slow films produce fine grain photos while higher ISO films (faster films) produced a more grained texture.
