In many circumstances you can use your flash in the day time. Let’s say you taking a photograph of someone sitting on a dock with the sun behind them. You either have the water well lit and the person dark or the person well lit and the water blown out. What to do? Turn on your flash. If you are shooting in manual, I hope, make your setting correct for the water and then turn on the flash. Voila the person is lit and the water is also beautiful. This can create some dramatic effects as well. This can also help with photos of people in dappled light, for instance under a tree. I prefer to have them move to a shaded spot but if you have no choice turn on your flash and that will help fill in the dark areas. Play with it.
