1 tip on exposure
Keep your pictures underexposed
The pictures you take should always be a little underexposed, especially when there is a lot of light around. The levels of those images should be later on fixed in Photoshop, but the results will be much more realistic.
The reason for that is that the human eye is more sensitive to the bright color changes than the dark ones, therefore keeping the image underexposed you allow the camera to capture a wider range of bright colors.
