ISO Experiements

When planning a shoot, it is important to consider the type of lighting that is available as not only will it determine the overall exposure, but it will also have an influence on the camera settings that you will use. ISO dictates how sensitive the camera is to light, so the higher the ISO, the more light will be allowed into the sensor. It also allows for more grain or noise. 

In the series of videos below, I experimented with the way that adjusting the ISO setting on the camera affects the overall exposure of the video. I aimed to establish what visual differences occur when adjusting the ISO setting, and whether or not it has much of an effect at all.

I recorded this extreme close up of Beth using ISO 100, as I was in a bright outdoor environment. There is no grain visible and the subject is very clear to see. You can see all of the textures of Beth's face, eye and hair. 

I recorded this panning mid-shit of Beth in the photography studio using a single LED light source and an ISO of 16000. You can see that the video is more grainy than when I shot using ISO 100 and the details are less clear.
