Photography
Depth of Field Calculator
Estimates the total depth-of-field range in millimeters from focal length, aperture, and subject distance, assuming a full-frame sensor. Use it when choosing settings for portraits, landscapes, or macro shots.

Photography
Crop Factor Calculator
Calculate the full-frame equivalent focal length of a lens on a crop-sensor camera by multiplying the actual focal length by the sensor's crop factor. Use it when comparing lenses across systems, predicting field of view, or planning gear purchases.
