I seldom manage to get up at dawn, in view of the fact that I am a lover of sleep and am well friends with laziness. But the situation changed a little - I became a dad, which means that now the child decides when his parents to sleep. But now stand up at dawn - just spit!
Sunrise is of two types: with and without clouds. When there are clouds, then the dawn can paint them in bright beautiful colors. In this case, you need to shoot against the light.
Lateral light may not give a beautiful picture, as the sun is still low and a lot of space is in the shade.
Although in part may be interesting non-standard lighting facilities.
If there is no sky, then the best is to use the front yellow light, which looks favorably against the contrasting blue sky.
In this case, the objects will be like "burn".
