Exposure (photography)

Exposure in photography means how much light goes into the camera to create a photo. It is like cooking pasta - you need just the right amount of water to make it perfect!

When a photo is taken, the camera's lens opens up for just a few seconds to let light come in. The amount of light that comes in is very important to create a great photo. If the camera gets too much light, the picture will look too bright, and if it gets too little light, the picture will look too dark.

There are three main things that control the exposure of a photo: the aperture, shutter speed, and ISO. The aperture is like the size of the hole in your camera that lets light in. When the aperture is big, more light comes in and the photo looks brighter. When it's smaller, less light comes in and the photo looks darker. The shutter speed is like a curtain that opens and closes to let light in. The longer the shutter is open, the more light comes in and the photo looks brighter. A shorter shutter means less light and a darker photo.

Finally, ISO is like sensitivity in listening to a sound. When the ISO is higher, the camera is more sensitive to light and the photo looks brighter. But when it's lower, the photo looks darker.

So, exposure is like making the perfect pasta dish - you need to balance the right amount of water, heat, and ingredients to make it perfect! In photography, it's about balancing the aperture, shutter speed, and ISO to create a well-exposed photo.
