1. It means that the picture needs to have a good amount of lighting if there is too little it will be under exposed and really dark and if it’s too bright it will be overexposed and really washed out. If you are moving around a lot the picture will be out of focus and blurry so you want a focused picture you want to keep the camera steady.

top right- overexposed

main thing and nothing else
c)the auto means automatic mode and it basically does
everything for you so it uses the correct exposure and focuses for you

gives you a little more control over things like flash
