There is just a tiny chance that the problem might just be that chaiyah doesnt know what "overexposed" means.
Chaiyah, have you ever used a non-automatic camera, or seen anyone use it?
A non-automatic camera has time controls. You have to choose yourself whether you leave the lense of the camera open for 1/1000th of a second, for 1/60th of a second, or even for 1/2 a second, when you take the picture.
The longer you leave the lense open, the more light flows in, and onto your film.
If I point my camera at a daylight street scene, I have to put it at 1/250th second. If I put it at too long a time, too much light comes in, and the picture will be "overexposed" - it will be
too light. Everything in it will appear too light. You'll have seen pictures like that, I'm sure - you just think, oh, this one didnt work, and you throw it away.
Same thing in the evening. If I take a picture when its dark, you gotta take a longer time - say, 1/30th or 1/15th of a second if its still dusk, even longer in the night - to get the picture to look like what my bare eyes saw. If I leave the lense open for too short a time, too little light will get in, and the picture will be too dark, black even. If I leave it open too long a time, every point of light in reality will turn into a big blot of light on the picture.
Thats what rosborne is talking about. The full circular, lit orb in the sky you see in the picture is what happens when you point a camera at a much smaller point of light, a 5% crescent moon for example, and leave the lense open for too long. You can try it out if you want, just ask around if anyone's got an old-fashioned camera and see - then you wouldnt have to be scared of this orb anymore.
Remember, a camera is not a miracle machine, it doesn't
automatically register what you see - it's a technical appliance. To get what your bare eyes see onto a picture, the camera has to
do things. Only by allowing just enough light in, for example, does the film get to "catch" what you see with your eyes. If too much light gets in, things start looking very differently from what you would see with your own eyes. The sun, that coin-sized disk you see in the sky, would end up a huge, sky-covering ball of light. The moon, that dime-sized crescent, would end up looking like a big white blot. What rosborne is explaining you is thats exactly what happend in these here pictures.
