D asked:
Why do posters and photos fade over time? why is it they fade quicker, in bright rooms, and when they are put near light?

Well, the cause of the fade is the color’s being bleached over time and or abraded by people or objects laminating it will definitely help with the abrasion but will help less with the bleaching I would suggest keeping it in slightly darker conditions
The problem is Ultra Violet light fades the pigments. Laminating may not be too effective, but glass is a very good Ultra Violet filter so the pictures take much longer to fade, specialist glass can get rid of the problem totally, its expensive quartz glass used by museums and some galleries.
Modern pigment inks mainly from Epson have virtually eliminated this problem. Companies such as Lyson produce archival inks which are guaranteed not to fade for 80 + years, which is far in excess of any photographic emulsion type print.

Conventional black and white prints do not fade – they are composed of fine particles of metallic silver and will last essentially forever if the processing was done properly. Pt/Pd prints will last as long as the paper they are printed on.
Color prints, however, rely on dyes, and those dyes will fade over time. The rate of fading can be controlled by protecting the image from harmful light – direct sunlight, fluorescent illumination, etc.
