This type of light produces less contrast, reducing the chances of strong shadows or blown-out highlights. I like the warm glow as it adds a pleasing feel to the scenes and I find that the long shadows help to pick out details which of course adds texture and depth to the images.
But the really big benefit is that there are usually few people or vehicles around at dawn (usually 1 hour before sunrise), and so when taking photos of structures, there tends to be a far better chance of gaining complete access to the subject.
Enjoy the dawns early light! These were from last October and November.
