Accurately calculate depth of field and hyperfocal distance for your specific camera sensor. Essential photography tool for focus and bokeh control.
AI Generation Prompt
Professional Depth of Field and Hyperfocal Distance Calculator
Overview
A comprehensive, high-performance web-based utility for photographers to compute critical optical focus parameters. The application prioritizes real-time feedback, mobile-first design, and professional-grade precision.
Core Features
- Live Calculations: Instant updates as sliders or inputs are adjusted, eliminating the need for a 'Calculate' button.
- Sensor Database: Preset selection for popular sensor sizes (Full Frame, APS-C, MFT, etc.) with custom Circle of Confusion (CoC) manual override.
- Unit Flexibility: Toggle between meters, centimeters, feet, and inches.
- Visual Focus Guide: A dynamic graphical representation showing the 'Near Limit', 'Far Limit', and 'Hyperfocal Distance' on a scalable axis.
- Bokeh Preview Indicator: A qualitative estimation indicator showing the relative amount of background blur.
User Interface and Design
- Visual Style: Clean, high-contrast 'Dark Mode' interface to preserve night vision during shoots. Uses monochromatic UI with high-contrast accent colors (e.g., deep orange for critical data).
- Input Controls:
- Large, touch-friendly range sliders for Aperture (f-stop), Focal Length (mm), and Focus Distance.
- Dropdown menus with search functionality for camera sensor selection.
- Layout Structure:
- Header: Simple navigation and unit settings.
- Main Dashboard: Top-positioned input section, followed by a large, interactive chart showing the Depth of Field range.
- Output Panel: Large, legible typography for final values (Hyperfocal Distance, Near/Far Limits, Total DoF).
Technical Specifications
- Framework: Vanilla JavaScript or lightweight React for maximum performance.
- Responsiveness: Fluid layout that scales from smartphone displays to desktop monitors.
- Performance: Offline-first architecture using a Service Worker for immediate access in remote shooting locations without cellular service.
- Accessibility: Full keyboard support and screen-reader optimized labels for all input fields.
Interactive Features
- Shareable Links: URL parameters allow users to save specific calculations as bookmarks or share settings with other photographers.
- History Tracking: Local storage saves the last 5 calculations for quick reference.
- Print-Friendly View: A simplified version of the results for printing pocket-sized 'cheat sheets' to carry in camera bags.

Frequently Asked Questions
Everything you need to know about using this application.
How does this depth of field calculator work?
The calculator uses standard optical physics formulas based on your selected camera sensor size, lens focal length, f-stop (aperture), and focus distance to determine the depth of field range.
What is hyperfocal distance and why is it important?
Hyperfocal distance is the closest focus distance where everything beyond it is in acceptable focus. Using this distance ensures maximum depth of field, making it vital for landscape photography.
Can I use this for portrait photography?
Yes. By inputting your camera and lens settings, you can determine exactly how much background blur (bokeh) you will achieve, helping you isolate your subject effectively.
Does this tool support different sensor sizes?
Yes, it includes a comprehensive database of camera sensor formats including full-frame, APS-C, Micro Four Thirds, and medium format to ensure accurate Circle of Confusion calculations.
