Notes About the Live View Image
Under low- or bright-light conditions, the Live View image might not 
reflect the brightness of the captured image.
If the light source within the image changes, the screen might flicker. If 
this happens, stop the Live View shooting and resume shooting under 
the actual light source to be used.
If you point the camera in a different direction, it might throw off the Live 
View image’s correct brightness momentarily. Wait until the brightness 
level stabilizes before shooting.
If there is a very bright light source in the picture, such as the sun, the 
bright area might appear black on the LCD monitor. However, the actual 
captured image will correctly show the bright area.
In low light, if you set the [6 LCD brightness] to a bright setting, 
chrominance noise may appear in the Live View image. However, the 
chrominance noise will not be recorded in the captured image.
When you magnify the image, the image sharpness may look more 
pronounced than it really is.
