Exposure value

Exposure Value (EV) is a numerical representation of a photographic exposure, which considers the combination of aperture (f-stop), shutter speed, and ISO sensitivity. It provides a way to quantify exposure settings in a way that allows photographers to evaluate different exposure configurations while maintaining the same level of brightness in an image. Here's a breakdown of the components: 1. **Aperture (f-stop)**: Determines how much light enters the camera. A lower f-number (e.g., f/2.
