Time smearing

When we take a picture, we want it to be clear and sharp so we can see everything in it. But sometimes, things move too fast or too slow for the camera to capture them properly. That's when we get something called time smearing.

It's like when you try to draw a picture really quickly and your hand moves too fast or shakes a little bit, so the lines aren't straight or they blur together. The same thing can happen to a camera when things are moving too quickly. The camera tries to capture what's happening but it gets blended together and looks blurry.

To fix this, we use a technique called "exposure time." This means we leave the camera lens open for a longer or shorter amount of time depending on how fast or slow the thing we're trying to capture is moving. If it's moving really fast, we need a shorter exposure time so the camera can capture it quickly and make it look clearer. If it's moving slower, we can use a longer exposure time so the camera has more time to capture it and make it look sharper.

Overall, time smearing is just a fancy way of saying that things can look blurry in a picture if they're moving too fast or too slow for the camera. But with the right exposure time, we can make sure everything looks nice and clear in our pictures!
