Definition: ISO measures the sensitivity of the image sensor. Higher numbers mean your sensor becomes more sensitive to light which allows you to use your camera in darker situations. Hildebrandt (undated,online) says, “ISO represents the sensitivity of your camera’s digital sensor to light.”

This weeks task was to go and take pictures at different ISO’s, I wanted to do street portrait photography so I was looking for shops with neon lighting because I wanted to have a low ISO as it creates noise.
Here is an example of what ISO I should use in situations

Now this is just a rule of thumb because the photos that I took had an ISO of 400 and I was outdoors in the dark but because I had bright lighting coming from the neon signage I had significant lighting. The lighting was a great asset as it was late a night, approximately 10:30pm but I didn’t have to use a high ISO because I had natural light reflecting and glowing so I could visibly see my model.
I am going to show all my colour grading and different techniques on my next post.
