Frequently Asked Questions
What is depth of field?
The range of distance in a photo that appears acceptably sharp. A shallow DOF blurs the background (great for portraits), while a deep DOF keeps everything sharp (great for landscapes).
How does aperture affect DOF?
Wider apertures (lower f-numbers like f/1.4) create a shallower DOF. Narrower apertures (higher f-numbers like f/11) create a deeper DOF.
What is circle of confusion?
A technical limit for how large a point of light can appear and still be perceived as sharp. It varies by sensor size — larger sensors have a larger circle of confusion.
