aDoF

A beginner-friendly depth-of-field calculator that visualizes the in-focus range in front of and behind the subject, angle of view, and background blur.

aDoF is a photography tool that calculates depth of field from focal length, f-number, subject distance, and sensor size, then displays the result graphically.

Move the rulers and watch the results update in real time. Instantly check the near and far limits, depth of field in front of and behind the subject, total depth of field, and hyperfocal distance.

The shooting preview helps you visualize how focal length and aperture affect angle of view and background blur.
