Flash Key
In all lighting there is a light that is the main or ‘key’ light. Often this is the brightest light like the sun, but not always. The “key” light is always the dominant light and that makes flash key the brightest or main light. When you take the disposable camera to the birthday party and snap a picture, or you have set your digital camera on P for program, turned on the flash and snapped the same photo, the result usually is a flash key photo. This means that the subject has been brightly illuminated by the flash and with little regard for the background. (Remember 1/60 limit in P mode?) These are the “happy snaps” we all take at various events to record them. The result is often a flashed subject and dark background and it means flash was the key light.The content you are trying to access is only available to members. Sorry.

Flash fill

Flash fill is a very useful tool for photographers. Both film and digital cannot record the range of contrast in a photo scene like our eyes can. In very bright situations, the perfect exposure will favor the highlights in the scene and often to the detriment of the shadows. Flash fill can add light to the shadows areas reducing the harsh contrast created by bright sun or ambient light. It can also brighten up dull images that are taken in flat light. In fact I always recommend the use of a flash whenever shooting people and most subjects in full sun.The content you are trying to access is only available to members. Sorry.

This series shows flash fill at different settings from flash -1/3 all the way to flash -2 and no flash. I usually use -1 to -1 2/3 for people outdoors. The ambient brightness helps determine which setting I use. For example, if the sun is very bright I will use -1 and if the light is soft I will use -1 2/3 for a little ‘bump’ of light into the shadows.The content you are trying to access is only available to members.

How to use Flash Fill in TTL

The simplest way to create flash fill is to use FEC on your camera and/or flash and the description on how to do that is earlier in the lesson. On the Canon and in A mode, you press the FEC +/- button on the camera and turn the Quick Dial for the desired amount of flash fill. Here we are showing a -1 flash fill.The content you are trying to access is only available to members. Sorry.

Diffused Flash

It is no secret that on-camera flash directed at the subject produces a very harsh and contrasty light. This is often necessary to get the photograph. But there are some things that you can do to soften the light some for a more pleasing effect.The content you are trying to access is only available to members. Sorry.

This magazine cover was photographed using a diffused flash right next to the camera on the right. The flash was a key light while the ambient was the fill light.The content you are trying to access is only available to members. Sorry.

Swivel heads

Most of today’s flashes allow the head to be swiveled and this allows you to point the flash in a variety of directions. If the photo is a vertical then the flash is on the side and the ability to bounce requires your to swivel the head instead of tilt to bounce light for any type of image.

Key points to remember:

1.)  Aperture controls the amount of light allowed to expose the picture.

2.)  Shutter speed controls the amount of time the picture is exposing, but

not the actual flash exposure.

3.)  You can control the flash exposure by moving the flash closer or
