3Set [Multi-expos ctrl].
  Select the desired multiple-exposure 
control method, then press < 0>.
  Additive
The exposure of each single exposure  is added cumulatively. Based on 
the [No. of exposures], set a negative exposu re compensation. Refer 
to the basic guide below to set  a negative exposure compensation.
Exposure Compensation Setting Guide for Multiple ExposuresTwo exposures: -1 stop, three exposures:  -1.5 stop, four exposures: -2 stops
 Average
Based on the [ No. of exposures ], negative exposure compensation 
is set automatically as you shoot  multiple exposures. If you shoot 
multiple exposures of the same scene, the exposure of the subject’s 
background will be automatically controlled to obtain a standard 
exposure. If you want to change the exposure of each single 
exposure, select [ Additive].
  Bright/Dark
The brightness (or darkness) of the base image and the images to 
be added are compared at the same  position, and then the bright (or 
dark) part will be left in the pi cture. Depending on the overlapping 
colors, the colors may be mixed depending on the brightness (or 
darkness) ratio of the compared images.
4Set the [No. of exposures].
  Turn the < 5> dial to select the 
number of exposures, then press 
< 0 >.
  You can set it from 2 to 9 exposures.
If [On:Func/Ctrl] and [ Additive] are both set, the image displayed 
during shooting may look  noisy. However, when you finish shooting the 
set number of exposures, noise reduction will be  applied and the final 
multiple-exposure imag e that is recorded will have less noise.

8Shoot subsequent exposures.
X When [On:Func/Ctrl ] is set, the merged multiple-exposure 
image will be displayed.
  With Live View shooting, the mu ltiple-exposure images merged 
so far will be displayed. By pressing the < B> button, you can 
display only the Live View image.
  After you shoot the set number of  exposures, multiple-exposure 
shooting will be canceled. With  continuous shooting, after you 
finish shooting the set number of  exposures while holding down 
the shutter button, the shooting will stop.
  With multiple exposures, the more  exposures there are, the more 
noticeable the noise, irregular colors , and banding will be. Also, as noise 
increases with higher ISO speeds,  shooting at low ISO speeds is 
recommended.
 
If [Additive] is set, the image processing after taking the multiple exposures 
will take time. (The access lamp will light up for longer than usual.)
 If you perform Live View shooting while [On:Func/Ctrl] and [Additive] are 
both set, the Live View function will stop automatically when the multiple 
exposure shooting ends.
  In step 8, the brightness and nois e of the multiple-exposure image 
displayed during Live View shooting will be different from the final 
multiple-exposure image recorded.
  If [On:ContShtng ] is set, let go of the shut ter button after shooting the 
set number of exposures.
 
If the power switch is set to  or the battery is  replaced after you set 
multiple exposure settings, multiple -exposure shooting will be canceled.
 If you switch the sh ooting mode to  while shooting, 
multiple-exposure sh ooting will end.
  When multiple exposure  is set or during multiple-exposure shooting, you 
cannot use the grayed out fu nctions in the camera menu.
  If you connect the  camera to a person al computer or printer, multiple-
exposure cannot be set.
When [ On:Func/Ctrl ] is set, you can press the < x> button during shooting 
to view the multiple exposures taken  so far or delete the last single 
exposure (p.185).

Merging Multiple Exposures with an Image Recorded in the Card
 Images shot with highligh t tone priority set to [Enable], or with cropping 
information appended (p.331)  cannot be selected as the first single exposure.
 Auto Lighting Optimizer, peripheral  illumination correction and chromatic 
aberration correction will be disabled , regardless of the settings of the 
1  image selected as the  first single exposure.
 
The ISO speed, Picture Style, high ISO  speed noise reduction, and color space, 
etc., set for the first 1 image will also be set  for the subsequent images. If the first  1 image’s Picture Style is [Auto ], the [Standard ] Picture 
Style will be set for  the subsequent images.
  You cannot select an image  taken with another camera.

  Are there any restrictions on the image-recording quality?All JPEG image-recording quality  settings can be selected. If 41 or 
61 is set, the merged multiple-exposure will be recorded as a 1 image.
  Can I merge images recorded in the card?With [ Select image for multi. expo. ], you can select the first single 
exposure from the images recorded on the card (p.184). Note that you 
cannot merge multiple images already recorded on the card.
  Are multiple exposures possible with Live View shooting?With [ On:Func/Ctrl ] set, you can shoot multiple exposures with Live 
View shooting (p.199). 
  What file numbers are used for saving merged multiple-
exposures?
If all images are set to be saved,  the merged multiple-exposure image file 
number will be the serial number comi ng after the file number of the final 
single exposure used to create the merged multiple-exposure image.
  Will auto power off take effect during multiple-exposure 
shooting?
As long as [ 52: Auto power off ] is not set to [Disable], the power will 
turn off automatically after 30 min. of non-operation. If the auto power off 
takes effect, multiple-exposure shoo ting will end, and multiple-exposure 
settings will be canceled. Before star ting the multiple-exposure shooting, 
the auto power off will take effect as  set with the camera, and multiple-
exposure settings will be canceled.

Although using the self-timer or Remote Switch can prevent camera 
shake, using mirror lockup to prevent  camera vibrations (mirror shock) 
can also help when you use a super  telephoto lens or shoot close ups 
(macro photography).
1Set [Mirror lockup].
 Under the [ z3] tab, select [Mirror 
lockup ], then press < 0>.
  Select [Enable ] or [Enable: Mirror 
down w/ s], then press < 0>.
2Focus the subject, then press the 
shutter button completely.
XThe mirror will swing up, and the 
 icon will blink on the top LCD 
panel.
3Press the shutter button 
completely again.
X The picture will be taken.
  With [ Enable] set, the mirror will go 
back down when the shooting ends.
  If [Enable: Mirror down w/ s] is

 In very bright light such  as at the beach or a sk i slope on a sunny day, 
take the picture prompt ly after mirror lockup.
  Do not point the camera  toward the sun. The sun’s heat can scorch and 
damage the shutter curtains.
  If you use the self-timer and mirror  lockup in combination with bulb 
exposure, keep pressing the shutter  button completely (self-timer delay 
time + bulb exposure time ). If you let go of the shutter button during the 
self-timer countdown, there will  be a shutter-release sound, but no 
picture will be taken.
  During mirror lockup, shooting func tion settings and menu operations, 
etc. are disabled.
  When [Enable ] is set, single shooting will take effect even if the drive 
mode is set to co ntinuous. When [Enable: Mirror down w/ s] is set, 
the current drive mode will  take effect for the shooting.
  You can also use the self-t imer with mirror lockup.
  If 30 seconds elapse after the mirror  has locked up, it will go back down 
automatically. Pressing the  shutter button completely again locks up the 
mirror again.
  For mirror lockup shooti ng, using a tripod and Remote Switch RS-80N3 
(sold separately) or Timer Remote Controller TC-80N3 (sold separately) 
is recommended (p.179).
