>>14285587>I don't understand how taking light through a tiny hole somehow captures an image,It doesn't. I'll explain it to you like a retard. Imagine it was a monochromatic camera, so it can only take black and white pictures.
Camera is Italian for 'room' btw.
Light travels in a straight line until it hits something, then it 'reflects' at an angle. Just like sound. That something can be glass. A piece of glass that is specially designed to cause all the light to reflect to a single point is called a 'lens'. On the front of the camera is a 'lens'. This directs all the light to the back of the little dark room (remember our Italian lesson?). Between the lens and the back of the room generally there is a physical door called a 'shutter'. On the back of the little dark room would be an 'array' which is covered in a grid of tiny little censors.When you click the 'shutter' button and it makes that click, the shutter lets light pass from the lens and onto the array. If there's no light that hits a sensor, then it's black, if there's a little bit of light it's grey, if there's too much light it is pure white. The sensors turn light into electricity. There's some circuitry that then 'digitizes' that electricity, so now it's in numbers a computer can understand. So black might be 0. White might be 255. and you can have any number in between to specify shade. The camera creates a file that stores these numbers in a way that resembles the array...
0.10.20.35.45.60.80.100
This would look something like a line that get's progressively lighter as you go to the right because the numbers increase. If you have a whole array of these, you can recreate the original image.
Now of course there's way more to it. There's 'chip noise'. CMOS vs. CCD. Non-mechanical shutters. HDR etc. etc. and the most important thing I missed is a prism that divides the light into three colors.
