Understanding Depth of Field How It Affects Photos
Depth of field is the part of the image that appears sharpThe transition from sharp to un-sharp is gradualDepth can be shallow or deepIt is affected by: ◦ Aperture ◦ Distance from subject ◦ Focal lengthWhat is Depth of Field?
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?
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?
Aperture is a hole within a lens that controls the amount of light that is let inAperture is measured in f-stopsA large opening results in shallow depthA small opening results in deep depthWhat is Aperture?
A large opening results in a sharp foreground and a blurry background or a shallow depth of fieldA small opening results in a deeper depth of field Shallow DeepHow Does Aperture Affect Depth?
The Distance between you and your subject is important in determining depth of fieldThe closer you are to your subject, the shallower the depth of fieldHow Does Distance Affect Depth?
Focal length is an expression of the magnification power of a lens and is usually measured in millimetresIn other words, it determines how far a lens can zoom in or outWhat is Focal Length?
The smaller the focal length the greater the depth of fieldA smaller focal length creates a wider angle of view, which results in a deeper depth of fieldHow Does Focal Length Affect Depth?
Depth of field can be used creatively in photos to get interesting and beautiful resultsIt is affected by three things: ◦ Aperture ◦ Distance from the subject ◦ Focal lengthExperiment with depth of field in your photos to get new, beautiful results!Conclusion: Depth of Field
