Film speed

Film speed is like how fast or slow a camera takes pictures. Imagine you have a camera and you are taking pictures of your friends playing hide and seek in a dark room. Now, if your camera is slow, it will take a lot of time to capture the pictures, and by the time you take a picture, your friends might move, and the photo will come out blurry. But if your camera is fast, it can capture your friends even when they move around quickly.

In the same way, film speed is a measurement of how sensitive a film is to light. It determines how quickly the film can capture an image and how clear the picture will be. Films with low-speed will capture a very clear and detailed image, but it will require more light, and the camera must take more time to capture the image. On the other hand, films with high-speed can capture the images quickly, but they will have a grainy or blurry effect to them.

Therefore, what kind of film speed you choose depends on what kind of photo you want to take. If you're taking a picture in a well-lit environment, like outside during the daytime, you can use a slow-speed film and get a high-quality picture. But if you're taking pictures in a low light situation, you will need a high-speed film to capture the images quickly and accurately.

So, just like how you need to decide whether to move slow or fast while playing hide and seek to capture the perfect shot of your friends, you also need to choose the right speed of film to get the best image while photographing different things.
