How to Use a Flash Gun, my tips
With the addition of an inexpensive flash unit for bouncing flash, this harshness can be greatly reduced and will give your pictures a professional look. Another solution for cheaper compact cameras is a stick a doubled up piece of tape across the flash which will help diffuse the light, this may be an alternative to buying another piece of electronic equipment and learning to use it.
I take portrait photographs in my stall every weekend (Fridays, Saturdays, and Sunday,) and the flash is bounced off the white ceiling and the white background. It's so effective that I don't require the lighting rig I would normally use in the studio.
This technique is something you can easily set up in your own home. They key to bouncing a flash is a reasonably low the ceiling, and to set the flash, if you can, to fire two or three stops above the camera exposure. You can find this setting on the camera (not the flash). The icon on the button will be a plus and minus sign next to a flash symbol. Push the button and ask the flash to overexpose by +2 or +3, the lower the ceiling the less you'll have to overexpose. Bouncing a flash eats through the batteries due to the higher output required, so make sure you load up with batteries before your sessions.
Try and use your flash with your outdoor portrait photography. This is known as ‘fill in flash' and is particularly useful when the subject has their back to the sun, or for example under some trees on a sunny day. On a compact camera just turn the flash on, on a SLR you have more control. Push the flash button again on your camera and ask the flash to underexpose slightly (-1, -1.5), by underexposing slightly the lighting will be more subtle and less "rabbit" (in the headlights).
At night most cameras on auto setting with default to flash. You have very little control on a compact camera but on an SLR you can manage how bright the background is relative to the subject. If the light is low set your camera to AV, and set the aperture to the lowest number it will go to, 4.0, 5.0, 5.6 . Then without any over or under exposure set the flash to fire direct at the subject. You'll have to keep the camera steady as the shutter speed may drop to below 60 (60th of a second) If it's too dark and there's a risk of camera shake change the mode to program or P and see how low you can set that aperture.
