By "hazy and grainy", you may mean the atmospherics and ambient light a lot of folks use. Vue does a lot of nifty stuff with atmospherics, and by using the haze and fog, along with ambient lights, I tend to get a hazier feeling to my images. It depends on what effect I want in my image. At least half the time, I lean away from ambient lighting towards more direct lighting, usually add several more lights as well as sunlight. But then, art and opinions are subjective, aren't they? I'm looking out my window right now, and the sky is a bit dull and overcast, and the colors in the landscape are a bit muted. "Hazy and grainy." Suggest you go back through the gallery, you will see plenty of vivid coloring in Vue renders.
