if you are working in max 2008-2009 you switch on mr photographic exposure in effects and controll exposures.
secondly daylight system always needs to be used with very low multiplier factor such as 1. to .3 ..... value of 1 always givs burnt effects.
If using MR then use skyportal which will enhance your scene. but for sky portal you need to enable mental ray light shader from within light parametrs.
OOOOSH! there are two many things. just try these triks! C U
