3 Setting the FlashN Built-in Flash Settings Flash mode Normally, set this to [E-TTL II]. This enables autoexposure shooting with the built-in flash. To set the flash output level manually, select [Manual flash]. Select [2flash output], then set the flash output level to within 1/1 - 1/128 (1/3-stop increments) before shooting. Shutter synchronization Normally, set this to [1st curtain] so that the flash fires immediately after the exposure starts. If [2nd curtain] is set, the flash will fire right before the shutter closes. When this is combined with a slow shutter speed, you can create a trail of light such as from car headlights at night. With second-curtain synchronization, two flashes will be fired: once when you press the shutter button completely, and once immediately before the exposure ends. When using second-curtain synchronization, set the shutter speed to 1/25 sec. or slower. If the shutter speed is 1/30 sec. or faster, first-curtain synchronization will be used automatically even if [2nd curtain] is set. 197
