I must add that haze and fogs are very difficult to adjust. I mean you want haze and fog in the background, you will have even a little amount of this in the foreground. Which will makes your pictures a little bit uniform in look. Very difficult to adjust. As it has been said above, try to highly decrease ambient light, which makes picture appear flat and dull. You will have to replace them by additional lights. That's why, a new Vue picture should always been done with a real "scratch" atmosphere. An atmosphere with zero ambient, zero fog, zero haze, white sky,...Creat it then save it and always begin a new scene with it, you can adjust the new atmosphere after... Beware there are other settings I don't know in Vue4 which are related with atmospheres and could disturb your "zero" atm. Yves
