Calculate Shutter Time

Formula

To calculate the Shutter Time:

\[ ST = \frac{500}{EFL} \]

Where:

Shutter Time Definition

Shutter Time is the duration for which the camera's shutter remains open to expose the sensor to light. It is calculated by dividing a value of 500 by the equivalent focal length in millimeters.

Example Calculation 1

Let's assume the following value:

Using the formula:

\[ ST = \frac{500}{50} = 10 \]

The Shutter Time is 10 seconds.

Example Calculation 2

Let's assume the following value:

Using the formula:

\[ ST = \frac{500}{100} = 5 \]

The Shutter Time is 5 seconds.
