Last episode we discussed how much light exposed to camera is captured by it so that we got to understand about why light is an important factor. Check it out. What is Light? Light is a electromagnetic radiation. Electromagnetic radiation consists of many rays like gamma rays, X-rays, UV-rays, infrared rays and so many in that visible spectrum. You can see up to 400nm-700nm through human eye below 400nm are UV rays and above 700nm are infrared rays we cannot see these but camera can capture it when this happens. It may affect the image quality or the color may also change so for that, there are UV filters and infrared filters are available in the market, these filter can be used. Without UV filter With UV filter We will talk about it in detail in our future, now let us have a basic understanding about them. So light travels in wave form in vacuum and travels straight, all these we learnt in our schools So this is a basic ...
