Subject: Flash as main Light

When shutter speeds drop below 1/60 of a second when using big lenses, especially with teleconverters, using the flash as main light technique creates better images. Even with low-light lenses it is easier to make sharp images with flash as main light because the effective shutter speeds are measured in many 1/1000ths of a second (the duration of the flash). Many prefer to work in manual mode, also. In most cases, it is good to underexpose the background by 1 to 1 2/3 stops and set the flash to "0" compensation, in other words, full flash.

In most cases, our modern smart flashes will expose the subject perfectly. However, when using flash as fill, we always reduce the flash to some degree, usually between 1/3 and 1 1/3 stops (with greater reduction for digital photography).

To increase the effective range of the flash on bigger lenses and avoid wasting light and thus battery power, it is good to use a flash booster which comes by several market names, such as: Better Beamer; Kirk Flash Extender, etc.
