For one of my first assignments in my Photography class this semester, I had to take photos that explored the Exposure Triangle adjusting the settings in Manual mode (ISO, Shutter Speed, and Aperture). ISO stayed relatively the same throughout this assignment since I was shooting outdoors in sunlight.
Shutter Speed
For the Shutter Speed portion, the assignment said to change the shutter speed while maintaining good exposure. I had to choose a subject in motion, so I chose a fountain at my University.
With a higher shutter speed, the water appears to be frozen in place. Whereas the lower shutter speed makes the water blur more. I’m sure that if I had my tripod and went to an even slower shutter speed, I could probably get a photo with that cool blurred water effect.
Aperture
Aperture is the setting that affects whether or not the background of the image is in focus. A larger aperture (smaller number e.g. f/1.4) creates a small depth of field with the subject in focus and the background out of focus. A smaller aperture (larger number e.g. f/22) creates a large depth of field where both the subject and the background are in focus.
Creating the smaller depth of field is great for Portrait photography because it emphasizes the person in the photo more.
Exposure
This part of the assignment was kind of putting everything I learned together. I had my ISO at 400 for all the photos to the right.
For the first two in the sequence, the shutter speed was set to 1/100 and each one was a different aperture.
For the last two in the sequence, the aperture was set to f/11 and each one was different shutter speeds.
