During continuous shooting, the continuous shooting speed will decrease
o
greatly.
Only the merged multiple-exposure image will be saved. The images taken in
o
steps 6 and 7 for the multiple-exposure image will not be saved.
The image quality, ISO speed, Picture Style, high ISO speed noise reduction,
o
color space, etc. set for the fi rst single exposure will also be set for the
subsequent exposures.
You cannot set an aspect ratio for multiple-exposure shooting. Images will be
o
taken with a 3:2 aspect ratio.
If white balance bracketing, Multi Shot Noise Reduction, HDR mode, or a
o
Creative fi lter is set, multiple-exposure shooting cannot be set.
During multiple-exposure shooting, the settings of [ z : Lens aberration
o
correction], [ z : Auto Lighting Optimizer], and [ z : Highlight tone
priority] will be automatically switched to [Disable].
If [ z : Picture Style] is set to [Auto], [Standard] will be applied for shooting.
o
With multiple exposures, the more exposures there are, the more noticeable
o
the noise, irregular colors, and banding will be.
If [Additive] is set, the image processing after taking the multiple exposures
o
will take time. (The access lamp will light up longer.)
If you perform Live View shooting with [Additive] set, the Live View function
o
will stop automatically when the multiple-exposure shooting ends.
In step 7, the brightness and noise of the multiple-exposure image displayed
o
during shooting will be diff erent from those of the fi nal multiple-exposure
image recorded.
Multiple-exposure shooting is canceled if you set the power switch to < 2 >
o
or switch batteries or cards.
Multiple-exposure shooting ends if you switch to a Basic Zone mode or to
o
< w / x >.
If you connect the camera to a computer, multiple-exposure shooting will
o
not be possible. If you connect the camera to a computer during shooting,
multiple-exposure shooting will end.
The shooting information for the last shot will be recorded and appended to
o
the multiple-exposure image.
