Question

reflection - aperture practice
answer each question in complete sentences.

1. which aperture (f - stop) has the shallowest depth of field?
2. which aperture (f - stop) has the deepest depth of field?
3. why did the depth of field change in your photos? explain in two sentences and be specific.
4. was there a change in exposure? why or why not? explain in two sentences and be specific.

Explanation:

1. A lower f - stop number (e.g., f/1.4) has the shallowest depth of field as it allows more light in and blurs the background more.
2. A higher f - stop number (e.g., f/22) has the deepest depth of field, keeping more of the scene in focus.
3. The depth of field changes in photos because the aperture controls the amount of light and the area in focus. A wider aperture (lower f - stop) blurs the background, while a narrower aperture (higher f - stop) keeps more in focus.
4. There is a change in exposure. A wider aperture (lower f - stop) lets in more light, increasing exposure, while a narrower aperture (higher f - stop) lets in less light, decreasing exposure.

Answer:

1. A lower f - stop number like f/1.4.
2. A higher f - stop number like f/22.
3. The aperture controls light and focus area. Different f - stops change what's in focus.
4. Yes, a wider aperture increases exposure, a narrower one decreases it.
