Canon 380EX - Manual (Page 34)

II. Speedlite 380EX with Type-B Cameras
(2) Flash with Shutter Speed-Priority AE
When you want to create a certain effect with the shutter speed, use
shutter speed-priority AE. In this mode, you set the sync speed anywhere
from 30 sec. to the camera’s maximum sync speed. The camera then
sets the aperture automatically to obtain the correct background
exposure. The TTL auto flash system controls the flash output according
to the aperture set automatically by the camera.
1 Set the camera to Tv (shutter
speed-priority AE) and set the sync
speed anywhere from 30 sec. to
the camera’s max. sync speed.
