### Depth of Field

1. 1. Understanding Depth of Field How It Affects Photos
2. 2. Depth of field is the part of the image that appears sharpThe transition from sharp to un-sharp is gradualDepth can be shallow or deepIt is affected by: ◦ Aperture ◦ Distance from subject ◦ Focal lengthWhat is Depth of Field?
3. 3. When a photo has a shallow depth of field, the portion of the picture that is in focus is smallWhat is a Shallow Depth of Field?
4. 4. When a photo has a deep depth of field, the portion of the picture that is in focus is largeWhat is a Deep Depth of Field?
5. 5. Aperture is a hole within a lens that controls the amount of light that is let inAperture is measured in f-stopsA large opening results in shallow depthA small opening results in deep depthWhat is Aperture?
6. 6. A large opening results in a sharp foreground and a blurry background or a shallow depth of fieldA small opening results in a deeper depth of field Shallow DeepHow Does Aperture Affect Depth?
7. 7. The Distance between you and your subject is important in determining depth of fieldThe closer you are to your subject, the shallower the depth of fieldHow Does Distance Affect Depth?
8. 8. Focal length is an expression of the magnification power of a lens and is usually measured in millimetresIn other words, it determines how far a lens can zoom in or outWhat is Focal Length?
9. 9. The smaller the focal length the greater the depth of fieldA smaller focal length creates a wider angle of view, which results in a deeper depth of fieldHow Does Focal Length Affect Depth?
10. 10. Depth of field can be used creatively in photos to get interesting and beautiful resultsIt is affected by three things: ◦ Aperture ◦ Distance from the subject ◦ Focal lengthExperiment with depth of field in your photos to get new, beautiful results!Conclusion: Depth of Field
