Day 7 was more about depth of field. Darcy suggests keeping your camera in aperture priority and taking a series of photos of something and noting the change in the depth of field. Naturally, I decided a bottle of wine was the best subject. I posted the photo with the largest and smallest aperture to highlight the big differences.
This photo is take with a large aperture, f/3.5. The bottle is in focus and the background blurry; shallow depth of field.This photo was taken with a small aperture, f/22. The fence, trees, and grass are in focus as well as the bottle; wider depth of field.
Day 8 explained the exposure triangle.
Book Suggested= Ordered
Day 9 discussed the exposure scales.
