Flash mode With an external Speedlite, you can select the flash mode to suit your flash shooting. [E-TTL II] is the standard mode for EX-series Speedlites for automatic flash shooting. [Manual flash] enables you to set the flash output yourself. This is for advanced users. Regarding other flash modes, refer to your Speedlite's instruction manual. Shutter sync. 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 exposure ends. When this is combined with a slow sync speed, you can create a trail of light such as from car headlights at night. With 2nd curtain sync, two flashes will be fired, once when you press the shutter button completely, and once immediately before the exposure ends. If an external Speedlite is attached, you can also set [Hi-speed]. For details, see the Speedlite's instruction manual. 140
