Let the shadows incorporate themselves into your scenic shots; even let them take center stage. If you are doing portraits, try to include scenery; the sunlight and shadows bring a certain beauty to an otherwise normal background. Be sure to bring along a fill flash so your subject’s face doesn’t turn out too dark, or have unflattering shadows. Using a flash in direct sun? You bet!
Try taking pictures in new settings; like a boardwalk for example. The light from the sun would make an interesting composition of lamp posts casting shadows on the wooden planks.
Full sun is also a perfect time to take ocean photographs, as the clear bright sun will penetrate the water in shallow areas, and allow you to photograph the ocean floor; something you couldn’t do in other light as you would usually just end up with reflection.
Shooting in black and white is another option; sunny conditions bring out these contrasting colors beautifully.
If you would like to adjust your settings manually, Sunny 16 is the way to go. Sunny 16 is a method of estimating the correct daylight exposures. This rule says to set your aperture to f/16 in full sun. The ISO should stay at around 100, and shutter speed to about 1/100 or 1/125. If you have a Nikon you’ll probably have to put the ISO at 200, and the shutter speed at about 1/200. This rule is a good starting point to work from, though you’ll likely have to adjust the settings to find which ones are best for your camera and conditions.
