![]() ![]() If the flash is off-camera, moving it closer or further away has as much impact on the result as changing the power or aperture. Image 5-15, an exciting tango for the couple's first dance, was made with the balance of flash and ambient light in mind. ![]() Now you’ve underexposed the background, set the flash to manual and begin by dialling in one-quarter power.ĭial it up or down, or adjust the aperture, to change the subject’s exposure. Power and distance play a big part in the exposure of your flash. Remember you cannot set more than your flash sync speed – unless you’ve a High-Speed Sync facility – check the camera/flash manuals. Your shutter speed controls the ambient light when using flash, so find a speed that underexposes the background to retain the glorious colour – here that’s 1/200sec. Set your camera to manual mode, dial in your preferred aperture and a low ISO. You need to take control of your exposure. In aperture-priority mode, spot metering and the flash set to iTTL, the system does a great job of filling in the shadows but fails to preserve the best of the background. Here you can see what happens when you leave your camera to work out the exposure. Set up your flashgun off-camera for dynamic lighting or keep it on-camera for speed and ease. Next, switch to spot metering to expose for the skin tones – this brightens the image but loses background colour and you still need light to fill in facial shadows. To learn how your camera handles backlit exposures, dial in a wide aperture in aperture-priority mode and multi-zone metering and take a shot – the camera will average the exposure to 18% grey and underexpose the subject. Position them against a dark background with the sky out of frame and you’ll likely get a balanced exposure using multi-zone metering and positive exposure compensation position them with the sun in the frame and you’ll get a wash of light and flare. Where you place your subject in relation to the sun can make a world of difference to how you approach exposing As the sun is low in the sky most of the day, you can generally shoot this type of portrait from 3pm. Semi-bare trees are useful for creating dappled sunlight and bokeh as well as blocking the sun’s orb to avoid flare. Making sure there are no buildings in the way can gift you more time. Pick an open space with the horizon visible to give yourself the most amount of time and the fewest background distractions.
