حول هذا التطبيق

Depth of Field (DOF) is the range of distance in a photo that appears to be in sharp focus ... Depth of field is a creative decision and one of your most important choices when composing nature photographs.

This Depth of Field calculator allows you to calculate :

• Near limit of acceptable sharpness
• Far limit of acceptable sharpness
• Total depth of field length
• Hyperfocal distance

The calculation relies on :

• Camera model or Circle of Confusion
• Lens focal length (ex: 50mm)
• Aperture / f-stop (ex: f/1.8)
• Distance to Subject

Depth of Field definition :

Given a critical focus achieved for the plane located at the Subject distance, the Depth of Field is the extended area in front of and behind that plane that will appear reasonably sharp. It could be considered as a region of adequat focus.

Hyperfocal Distance definition :

Hyperfocal distance is the lowest Subject distance for a given camera setting (aperture, focal length) for which Depth of Field extends to infinity.

In documentary or street photography, the distance to the subject is often unknown in advance, while the need to react quickly remains essential. Using hyperfocal distance allows for presetting the focus to achieve a sufficiently wide depth of field that covers likely subjects. This approach is especially useful for manual focusing, either when autofocus is unavailable or when one chooses not to rely on it. In landscape photography, hyperfocal focusing is valuable for maximizing depth of field—either by achieving the greatest possible range for a given aperture or by determining the minimum aperture needed to keep both the foreground and infinity in acceptable focus.
