Experiment with Exposure:
Digital cameras typically work best in sunlight, just like film cameras. Once you step inside or into dim light, things get a bit more difficult just like with film cameras. Experiment to know how to handle these situations.

If you can, shoot your subject from different angles and with different lighting. If you can manually turn off your flash, do so. Other flash settings can also be tried such as ‘fill flash.’ Sometimes even a perfectly exposed picture can be improved with fill flash. Other times turning off the flash leaving the subject underexposed can add an element of drama.

You can take the same photo three different ways using three different exposure options and the result will be three totally different pictures. What’s even better is that all three can look good, but you have to experiment.

Bracket your shots if you can, with one underexposed, one overexposed, and one ‘just right.’ You should still practice even with a digital camera that will do this automatically.
If your camera shoots three frames when you were expecting it to shoot one, the result will probably be the last two looking like they were taken by surprise…your surprise!
