Live View Shooting
You can shoot while viewing the image on the camera’s 
LCD monitor. This is called “Live View shooting.”
Live View shooting is effective for still subjects which do 
not move.
If you handhold the camera and shoot while viewing the 
LCD monitor, camera shake can cause blurred images. 
Using a tripod is recommended.
About Remote Live View Shooting
With EOS Utility (provided software) installed in your computer, you 
can connect the camera to the computer and shoot remotely while 
viewing the computer screen. For details, see the Software 
Instruction Manual in the CD-ROM.
