Canon MR-14EX - Manual (Page 22)

Using Flash with the Camera’s Shooting Modes
For E-TTL autoflash shots, just set the camera’s shooting mode to P
(Program AE), Av (aperture-priority AE), or M (Manual exposure). For
serious closeup flash photography, Av or M is recommended.
* When you press the shutter button completely, a preflash is fired
immediately before the picture is taken. The preflash Is used to obtain the
subject’s reflected-light reading for calculating the optimum output of the
main flash.
P: Program AE Mode and E-TTL Autoflash
Set the camera’s shooting mode to P, and the camera will set the flash
aperture and shutter speed automatically. You can thereby concentrate on
the subject.
Set the camera’s shooting mode
to P.
Set the MR-14EX’s flash mode to
ETTL.
Focus and take the picture
• Check that the J icon (flash ready) is
displayed in the viewfinder before
taking the picture.
Q • If the camera has the Full Auto mode a and It is set to this mode, the shutter
speed and aperture will be set In the same way as with the P mode (Program
AE).
• If the DEP mode (depth-of-fleld AE) is used with the MR-14EX, it will be the same
as using the P mode.
• If the Tv mode (shutter speed-priority AE) Is used to set the shutter speed, the
camera will set the flash aperture automatically. Since you cannot set the desired
aperture In this mode, it is not recommended for closeup flash photography.
