This Exposure Calculator offers a simple way to determine the optimal exposure settings for your photographic needs. Here's a step-by-step breakdown:

Shutter Speed: Input the desired time (in seconds) the camera shutter will be open to capture the image.

ISO: This represents your camera sensor's sensitivity to light. A higher ISO means the camera is more sensitive to light and can capture images in lower-light conditions, but might result in more noise.

 Aperture (f/stop): Choose from the dropdown the size of the lens opening. Lower f-numbers let in more light and create a shallower depth of field, while higher f-numbers provide a deeper depth of field and less light.

 Exposure Value (EV) Description: As you adjust or input these settings, the calculator will instantly compute the Exposure Value (EV) for you. The EV is a number that represents the combination of shutter speed, ISO, and aperture. For instance, an EV of -6 might correspond to a "Nighttime landscape under quarter moon".
