DepthField

See the plane of focus, near and far limits, blur, and hyperfocal distance move live as you adjust real camera and lens settings.

DepthField turns depth of field into an instrument you can see and manipulate.

Choose a camera and lens, then adjust focus distance, focal length, and aperture. The live depth rail shows calculated near and far limits, total depth of field, hyperfocal distance, and how blur grows in front of and behind the focus plane.

Built for photographers who want to understand the shot before pressing the shutter:

• A fixed logarithmic distance rail that behaves like a focus scale
• Live near, far, front, behind, and total-depth readouts
• Hyperfocal and infinity focus actions
• A bundled catalog of 45 camera bodies and 180 lens products
• Focal-length, aperture, and minimum-focus settings
• Standard and critical circle-of-confusion choices
• Feet-and-inches or metric measurements
• Offline operation with no account, ads, analytics, or data collection

DepthField is a planning and learning tool. Calculations use standard thin-lens depth-of-field formulas; real-world results can vary with lens design, focus breathing, subject detail, output size, viewing distance, and personal sharpness criteria.
