Depth of Field Calculator

Calculate near focus, far focus, total depth of field and hyperfocal distance for any sensor + focal length + aperture + subject distance. Seven sensor presets (full frame, APS-C, MFT, 1-inch, medium format, phone), every standard f-stop, metric or imperial. Standard CoC = sensor diagonal / 1500. For shallow-DOF portrait work, deep-DOF landscapes, or planning a macro stack.

Composition Grid Overlay

Drop a photo and overlay one of seven classical composition grids — rule of thirds, golden ratio, golden spiral (Fibonacci nautilus, four orientations), diagonals, centre cross, 16:9 safe frame, or a Fibonacci sun (φ lines + diagonals for dynamic symmetry). Adjustable line colour, opacity, weight. Export as PNG. For critiquing your own work, planning a crop, or teaching composition.

Sun Position & Daylight

Sunrise, sunset, golden hour, blue hour, civil / nautical / astronomical twilight, day length — for any latitude, longitude and date. Live world map showing the sub-solar point (where the sun is directly overhead on Earth right now), the day/night terminator, and direction lines from your location to where the sun rises, sits, and sets. Polar sky-chart for the local horizon view too. Implements the NOAA / Meeus solar-position math directly in your browser, accurate to within a minute or two anywhere on Earth. Use-my-location quick-button, eight city presets, click anywhere on the map to switch location.

Image Location Finder

Find where a photo was taken. First: read the EXIF GPS data your phone embedded when the picture was taken — exact coordinates, 100% confidence, plotted on an interactive map. Second: if GPS is missing or stripped, ask Claude vision to guess from visual clues (signs, architecture, vegetation, sky) with an honest confidence score and the reasoning behind it. OSINT-style geolocation that runs almost entirely in your browser.

Print DPI Calculator

Two modes: 'I have a print size, what DPI do I get?' or 'I want 300 DPI, how big can I print?' Drop an image to autofill the pixel dimensions, or type them in. Inches or centimetres, six common print presets per unit, a quality verdict at every DPI tier (300 pro / 240 great / 150 OK / 90 web-only / 0 pixelated). For photographers prepping prints, designers checking client deliverables, and anyone with a 12-megapixel phone shot wondering how big they can blow it up.
