FocusBand Field Kit
FocusBand Field Kit
A sensor-aware depth-of-field and hyperfocal planning studio for landscape, architecture, product, and documentary photographers who must lock sharp zones before they shoot. The core loop is pick a body and lens → set aperture, subject distance, and circle-of-confusion → read near/far limits and hyperfocal on a live DOF band → generate barrel-tape marks or focus-stack slices → save a shot card for the field. Ships with a dense seed library of bodies, lenses, CoC presets, and ready shot cards so first launch is fully usable—not an empty shell, not a photo diary, and not an EXIF browser.

Body & sensor bench: choose full-frame, APS-C, Micro Four Thirds, or medium-format CoC presets; override CoC in microns; save named camera bodies with crop factor applied to every calculation.

Lens kit builder: add focal lengths, maximum aperture, and minimum focus distance; pin a working kit for trips; instant equivalent-FOV readout when crop bodies are active.

Live DOF band: dual sliders for aperture and subject distance with large near-limit, far-limit, total DOF, and in-front/behind split; haptic ticks at hyperfocal and at infinity-safe zones.

Hyperfocal mark sheets: generate barrel-tape style distance marks for a chosen aperture set; preview mark spacing; share or print a one-page field strip for gaffer-tape on the lens.
Focus-stack planner: enter magnification or subj…
Focus-stack planner: enter magnification or subject scale, acceptable blur, and step rule; output slice count, start/end focus distances, and a ordered pull list for the rail or focus ring.

Sun & golden-window panel: optional location (while-in-use) computes sunrise, sunset, civil twilight, and sun altitude for a chosen date; mark a shoot window on a simple sky arc—no social map feed.
