Lenses and mirrors are super important in how cameras make images. They are like the building blocks of how we take pictures. Without them, modern photography wouldn’t work at all!

Let’s start with lenses.

Lenses have a unique ability to bend light. When light goes through a lens, it changes direction. This bending helps the camera focus light from different directions into one point, called the focal point.

This ability to focus is key for taking clear pictures.

For example, a converging lens (which is also called a convex lens) takes straight beams of light and brings them together to a single point. In contrast, diverging lenses (or concave lenses) spread the light rays apart.

Now, let’s talk about mirrors.

Concave mirrors are very important because they can change the direction of light. In some cameras, mirrors are used to help show the image in the viewfinder or send it to the sensor.

This change in direction is based on how light reflects off the mirror. It also helps us see a bigger area in the image. The angle at which light hits the mirror can also change how clear the image looks.

To get the best images, both lenses and mirrors need to be carefully shaped and lined up. If the lenses aren’t just right, they can make pictures look strange or blurry. That’s why many camera systems use several lenses working together to fix these issues.

In summary, without the smart use of lenses and mirrors, getting bright and clear images would be really hard. They aren’t just parts of the camera; they are key to the art and science of photography!
