Aperture Area Calculator (Aperture Diameter)
Frequently Asked Questions (FAQ)
How do you find the diameter of aperture?
- To find the aperture diameter use the formula: D = F/N. where F is the focal length and N is the f-number.
What is aperture diameter?
- The aperture diameter is the diameter of a hole or an opening through which light travels.
What is the formula for aperture area?
- To calculate the aperture area use the formula A = π (D / 2)², where D is the aperture diameter (mm), or the formula A = π (n/ (2 * f))², where n is the focal length (mm) and f is the f-number.
Is lower f aperture better?
- The lower the f-stop number, the wider the aperture letting more light through, resulting in a brighter image but also in a shallower depth of field.
