How it works
Choose your sensor and lens, explore the numbers, then save settings to a shot list. Everything runs in your browser. Use these estimates as a starting point and confirm results with your camera.
Frequently asked questions
How accurate are the calculations?
Enter focal length in millimetres, aperture, circle of confusion and subject distance. This thin-lens model estimates acceptable sharpness rather than a hard boundary. A smaller circle of confusion demands stricter sharpness. Distances are measured from the lens principal plane; macro magnification, pupil ratio, diffraction and lens-specific behavior are excluded.
Where is my shot list stored?
Create an establishing view, a main subject and a detail shot. Load example appends three editable shots. Up to 200 shots are saved in this browser; changing devices or clearing browser data will not preserve them. Export regularly if the plan matters.
