Calculate ISO Adjustment







Formula

The formula to calculate the ISO Adjustment (IA) is:

\[ IA = \frac{ISO \times EV}{SS \times AP} \]

Where:

Example

Let's say the camera's ISO setting is 400, the Exposure Value (EV) is 2, the Shutter Speed (SS) is 1/60, and the Aperture (AP) is 5.6. Using the formula:

\[ IA = \frac{400 \times 2}{\frac{1}{60} \times 5.6} \]

We get:

\[ IA \approx 8571.43 \]

So, the ISO Adjustment is approximately 8571.43.
