If the human eye cannot see blue without the rods and cones in their eyes, how does a camera see hues of blue?

Question

If we didn't have rods and cones in our eyes, we wouldn't be able to see color. How does the camera compensate for this?

Answer 1

Different photoreceptors respond more or less strongly to different wavelengths (colours) of light. Digital cameras use more than one type of photodector for each pixel of the picture. By comparing the strengths of the signals from different detectors you can tell what colour the pixel should be.

Film cameras do the same thing, but use different chemicals in the film instead of photodectors. The different chemicals respond to different wavelengths of light.

Answer 2

The different hues are mixes of blue with other colors.

Cameras are not organic and don't have rods and cones. For color film, there are at least three layers of emulsion that are sensitive to different colors.

Digital cameras typically use sensors and filters to differentiate between the colors.

Answer 3

weird question

the rods are our photo-sensitive cells, those that react to light and to colour (the cones only react to light but not to colour).

it's a bit as if you asked "if cameras didn't have a light sensitive chip, how would they see light"? Well, they would not ;-)

as a side comment, our eyes are about 125 megapixels, so a good 10x more than high-end cameras today (excluding models in the tens of thousands of dollars).

Answer 4

a camera has a screen (just like ratina), but it changes colours(according to wavelengths) into a digital form. but the rods and cones help the brain respond to different intensities of brightness and different colours.

Answer 5

it is pretty much the same as your eyes besides the camera just takes pictures when you print it out you will get the colors lol

Answer 6

Some old films couldn't. We developed dyes and photosenstive siver salts (and lately CCDs) to give us vibrant color images.
