Well, you probably saw this coming after the last two posts. It’s time for the third corner of the exposure triangle: ISO. As part of the homework for Nicole’s Photo 101 class, I was tasked with photographing something in natural light at ISO 100 and again at ISO 400 or greater to illustrate the difference in grain in the images.
The second half of the assignment was to photograph the subject indoors by setting the desired f-stop and shutter speed before adjusting the ISO to achieve proper exposure.
Grain is right, huh? Also, I forgot to white balance that last pic, but — spoiler alert — that’s part of week two’s homework.
