4. Flash photography techniques
Slow synchronization photography
Normal flash photography
<1. Slow synchronization photography>
Slow synchronization with the shutter speed set at 1/30 second or slower less can be effective for shooting evening or night views using a flash. Slow synchronization often adds more ambient light to the final picture. When the TLA flash’s TTL auto mode is used, photographs can easily be taken with slow synchronization.
❖When the exposure mode is set to “P” or “Av”
Determine the composition, then set the main switch to “AEL”. The shutter speed is locked at the metered value of the ambient light. Check that the flash is charged, then take the photograph.
❖When the exposure mode is set to “Tv”
Set the shutter speed to 1/30 sec. or less. Compose the picture and then set the main switch to “AEL”. The aperture is locked at the metered value of the ambient light. Check that the flash is charged, and then take the photograph.
❖When the exposure mode is set to “M”
Set the shutter speed to 1/30 seconds or less. Adjust the aperture to set the exposure to the metered value of the ambient light so that the exposure meter indicates that the exposure is appropriate, then check that the flash is charged and take the photograph.
•The shutter speed is slow when slow synchronization is used, so use a tripod to prevent camera shake.
Daylight synchronization photogra- phy
When no flash is used
<2. Daylight synchronization photography>
When taking photographs outdoors, for example of people in bright sun- light or lit from behind, the people tend to be dark in the resulting photo- graph. In such cases, photographs in which both the people and the back- ground are well exposed can be achieved by using the internal flash or the TLA flash in the TTL auto mode.
❖When the exposure mode is set to “P”
In bright scenes, the aperture and shutter speed are adjusted automatically and the daylight synchronization mode is set.
❖When the exposure mode is set to “Tv”
In bright scenes, the aperture is adjusted automatically and the daylight syn- chronization mode is set.
❖When the exposure mode is set to “Av”
If “125” flashes in the shutter speed indication after the flash is charged, the pic- ture will likely be overexposed. Decrease the aperture so that a shutter speed of under “125” is displayed, then take the picture.
❖When the exposure mode is set to “M”
When in the “M” mode, set the shutter dial to 1/125(✕125) or less. Adjust the aperture so that the exposure meter in the viewfinder indicates that the expo- sure is appropriate, then take the photograph.
