Experimenting with ISO in a studio with a black background and using one lamp for lighting – working from ISO 100 through the ISO 25600, and then back to ISO 200 for the last photograph – to see the effect of light on the image. As the ISO number increases more light is allowed on the light sensor at the back of the camera and the photographs get progressively brighter.
Unit 2 research
A photographer whose use of technical expertise of ISO that has schooled my camera skill is New York-based artist Khalik Allah. In particular, Allah’s collection of intimate portraits taken after sunset, using only available light, in a black neighbourhood, is a lesson in the art and science of photography.
Changing the ISO number had a really strong effect on the subject, and completely changed the look of the photograph. As the ISO number increased, more detail pops out and the subject becomes more dynamic – the photograph is generally more visually pleasing. I learnt that changing the ISO is a very useful technique to use when it is dark. In dark conditions, such as night time, one way of getting a good exposure is to change and increase the ISO. I will use this to improve my photography in the future.
