How to set up and use your flash outside
Balancing the exposure
Most automatic TTL (through the lens) systems will try to balance the flash exposure with the ambient light automatically, although you can often adjust the flash exposure using your camera’s flash exposure compensation feature.
If the subject is too bright, you need to set flash exposure compensation to -1; if it’s too dark try +1.
The only thing to remember is that there is usually a maximum shutter speed that will work with flash (usually around 1/200 sec), so don’t set the shutter speed any faster than this if you’re shooting in Shutter Priority or Manual exposure mode.
How to set the exposure in Manual
Using manual exposure and manual flash may seem like a black art to some, but getting it right is just a case of changing one setting at a time, and in the right order.
With your camera set to Manual and the lowest ISO, first you need to set your camera for the ambient light.
In bright conditions, choose the fastest shutter speed that your camera can use with flash (usually 1/200 sec), then adjust the aperture to give your shot a slightly under-exposed background. Take a test shot.
With the aperture now set, you can adjust the power and position of the flash. Most manual flashguns will have a dial or digital readout to indicate what distance will give the correct exposure at each aperture and power setting.
Using this information, you should manually select a power setting that gives a distance suitable for your subject and framing, which will usually be between full to 1/4 power in bright conditions.
Position your flash at the distance indicated from the subject and take a test shot. If the subject is too bright, either move the flashgun a little further away or use a lower power setting. If it’s too dark, move the flash closer or increase the power.
