Depth of Field Calculator vs Exposure Value Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
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.
- Answers
- Depth of Field (mm)
- Inputs
- Focal Length, Aperture (f-stop), Subject Distance
Exposure Value Calculator
Computes the Exposure Value (EV) at ISO 100 from aperture and shutter speed, giving a single number that represents the total light reaching the sensor. Use it to compare exposure settings or match lighting conditions across scenes.
- Answers
- Exposure Value (EV)
- Inputs
- Aperture (f-stop), Shutter Speed
