What do color filters do?
Color filters absorb certain wavelengths of color and transmit the other wavelengths allowing them to be seen. We know that light is the source of color. Color filters work the same way, absorbing certain wavelengths and transmitting the other wavelengths.
What Colours do Cameras capture?
It may be surprising, but pixels on an image sensor only capture brightness, not color. They record the gray scale—a series of tones ranging from pure white to pure black. How the camera creates a color image from the brightness recorded by each pixel is an interesting story with its roots in the distant past.
What color model does our digital camera capture images in?
sRGB
Almost all digital cameras are factory-set to capture colors using sRGB as the default color space for a plausible reason; most of the pictures we take never get printed! At best, we view them on computer monitors or social media.
Can digital cameras capture true Colours?
Why is it impossible to get accurate color from cameras? – Quora. The simple answer is because the camera sensors don’t have the same spectral response that human eyes have. In each case there are sensors that respond to red, green and blue, but the human eye response is very different from that of the camera sensors.
What are color filters made of?
Color filters are usually constructed using transparent pieces of dyed glass, plastic, lacquered gelatin (e.g. Wratten filters) that have been treated to selectively transmit the desired wavelengths while restricting others.
How do digital cameras take color images?
A digital camera uses an array of millions of tiny light cavities or “photosites” to record an image. To capture color images, a filter has to be placed over each cavity that permits only particular colors of light.

Why does purple look blue in pictures?
Violet light appears blue in many digital cameras and color films, but purple will usually appear purple. The reason that violet appears purplish to the human eye is due to a quirk of the response of the long wave cones (aka “red” cones). They actually respond to violet light which should be a deep blue.
