ISO Task

Iso is one of the three main components to how cameras capture images in the right exposure, the other two being shutter speed and aperture. Iso is a camera setting which brightens or darkens a photo depending on getting the right exposure or getting the desired way you want your images to look like. 

Typically ISO is used in darker environments as it allows you to brighten the image without the use of additional lights. However by increasing the ISO, it can add grain or 'noise' to your images so they don't appear as sharp as normal images. So the higher amount of ISO you use in an image, the grainer it will be so the quality deteriorates. 

The faster shutter speed with a high ISO can decrease or remove motion blur, giving the shot a cleaner sharper finish to it rather being blurred as people move around.

The ISO Values:

• ISO 100 (lowest)
• ISO 200
• ISO 400
• ISO 800
• ISO 1600
• ISO 3200
• ISO 6400 (highest)

This video is an example of shots with different ISO setting that we completed in Billy's lesson. You can see the comparisons of how the quality decreases as the ISO increases. For these shots the shutter speed stayed at 1/50. If I was to go back and redo these shots, I would use a tripod as the shots are shaky because I was holding the camera the whole time.

Grainy Effect:

The grainy look is sometimes wanted in clips on purpose, examples such as horror films like Paranormal Activity in the CCTV footage clips. The grain makes the effect of the clip look more realistic so the audience believe it more.
