Okay kiddo, do you know what colors are? Yes? Great! So, when we see things, different colors make up what we see because of light.
But, sometimes we want to separate the colors of light so we can study and understand them better. That's what an rgbe filter does! It stands for red, green, blue, and exposure.
Imagine a tiny camera filter with four different parts, like a pizza with four slices. The red slice only lets in red light, the green slice only lets in green light, the blue slice only lets in blue light, and the exposure slice helps adjust how bright the picture looks overall.
When we use the rgbe filter, we can capture each slice of color separately and then put them back together to create a picture that shows us more about the different colors of light that are around us. It's kind of like taking apart a puzzle to better understand each piece before putting it back together to see the whole picture.
So, that's what an rgbe filter is - a tool that separates different colors of light so we can learn more about them. Pretty cool, huh?
