Photography

Plan camera memory cards from stills, video bitrate, reserve, dual-slot mode, and speed class with capacity and write-speed checks.

Plan depth of field from lens, aperture, sensor format, focus distance, circle of confusion, background blur, framing, and motion checks.

Plan camera framing from sensor size, focal length, and subject distance with angle-of-view math, target-fit checks, and lens sweep data.

Plan macro focus-stacking rail steps from magnification, aperture, subject depth, overlap, and rail precision with frame counts and warnings.

Plan golden hour and blue hour times for a shoot by location, date, sun angle, arrival buffer, sun direction, and horizon cautions.

Match lenses across camera formats with target focal length, depth-of-field look, video crop adjustments, and practical lens candidates.

Calculate ND filter stops from metered and target exposure settings, then compare fixed, stacked, and variable filter choices for stills or video.

Look up passport, visa, and ID photo sizes, head bands, pixel targets, and print-sheet fit before preparing a crop or photo lab file.

Check photo print resolution from pixel dimensions, print size, crop reserve, target PPI, and framing mode before ordering or upscaling.

Build a time-lapse shoot plan with interval, clip length, frame count, storage, battery, and exposure-gap warnings before setting the camera.
