DEPTH OF FIELD CALCULATOR
Find your near/far focus limits and total depth of field based on focal length, aperture, subject distance, and sensor size.
DATA CALCULATOR
Quickly estimate how much storage your video footage or photos will require. Plan card sizes, drive space, and backups with accurate, camera-ready calculations.
Shutter Speed ↔ Frame Rate Tool
Quickly find the recommended shutter speed for cinematic motion blur (180° rule) at any frame rate.
Timecode Duration Calculator
Enter start and end timecodes to get the exact clip length at your chosen frame rate.
File Transfer Time Estimator
Calculate how long it will take to copy media files based on file size and transfer speed.
Aspect Ratio & Resolution Tool
Input pixel dimensions to get the aspect ratio and see which common format it matches (HD, 4K, anamorphic, etc.).
Lens Field-of-View Calculator
Find the field of view (degrees) your lens gives on different sensor sizes to help plan framing and coverage.
Required Focal Length Calculator
See how capture fps vs playback fps affects clip duration, slowdown factor, and total frames.
Crop Factor & 35 mm Equivalents
Convert any lens focal length to its full-frame (35 mm) equivalent based on sensor crop factor, and see the reverse (what focal you’d need on another format).
ND Filter & Exposure Stops Calculator
Convert between ND strength, stops, optical density, and light reduction factors. See how much you need to adjust shutter speed, aperture, or ISO to maintain proper exposure.
Slow-Motion Time Stretch Calculator
Enter capture and playback frame rates to see the slowdown factor, playback speed, and new clip duration, along with the total frames captured.
Battery Runtime Estimator
Estimate shoot time per battery based on watt-hours and camera/accessory power draw.
White Balance: Kelvin ↔ Mired & Gel Helper
Convert between Kelvin and Mired values, compare color temperatures, and find the correction gel strength (CTO/CTB/plus-green) needed to match light sources.
EV / Sunny Helper
Convert between EV and exposure settings, factor in ND filters, and get equivalent exposure pairs.
T-Stop ↔ F-Stop (Transmission) Helper
Convert between f-numbers and T-numbers, see the exposure gap in stops, and compare lens transmission.
Flash Guide Number Calculator
Solve GN = aperture × distance problems fast. Factor in ISO, power settings, and modifiers.
Time-Lapse Planner
Plan intervals, frames, and final clip length for time-lapses, with suggested shutter time for natural motion blur.
HDR Exposure Bracketing Planner
Build a bracket set (frames, step size, sequence) around your base exposure and estimate total capture time.
Panorama Stitch Planner
Plan pano grids with columns, rows, and overlap to cover your scene, with estimated final megapixels.
Shutter Angle ↔ Shutter Speed + Flicker Safe
Convert shutter angle ↔ shutter speed, snap to 180° rule, and find flicker-safe speeds for 50/60 Hz lights.
