Exposure is how bright or dark your finished photo looks. Cameras capture a certain amount of light during each shot. Too much light and the image looks washed out, with pale skies and lost detail. Too little light and shadows turn into black blobs with no texture inside. Good exposure keeps important details visible in both bright and dark areas. Your goal is not always perfect middle gray. Your goal is showing the story you care about with readable detail.
⚖️ BALANCE
Exposure is the total amount of light recorded, controlling overall brightness in the image.
