Re: How the physical camera works?

The physical camera works like a real world camera, and therefore one of its primary functions is exposure. Proper exposure is essentially achieved by matching the exposure levels to the level of illumination within your scene. If there is too much illumination in comparison to your exposure level, then your image will be too bright, or even completely white. If there isn't enough illumination in comparison to your exposure level the your image will be too dark, or even completely black (what you experienced). In essence its not really a question of the illumination of a scene being right or wrong when it comes to using the physical camera, but rather that the illumination level matches the exposure of the camera.

Exposure itself can be controlled through Shutter Speed, F-Stop, and ISO value. Both Shutter Speed and F-Stop will work inversely, or in other words, larger values will lead to a darker image. ISO will work in a much more linear fashion, so larger values will lead to a brighter image.

I can go deeper, but I'd rather not write 2-3 pages on it if I can help it. If you want to know a bit more of the "theory" or "nature" of whats actually happening then let me know because its a fairly involved question once it goes beyond what I've already said. Hope this helps
