In this mode, the shutter stays open as long as you hold down the 
shutter button completely, and closes when you let go of the shutter 
button. This is called bulb exposure. Use bulb exposures for night 
scenes, fireworks, astronomical objects, and other subjects requiring 
long exposures.
1Set the Mode Dial to .
2Set the desired aperture.
  While looking at the LCD panel, turn 
the < 6> or < 5> dial.
3Take the picture.
  The exposure will continue for as long 
as you keep the shutter button 
pressed completely.
X The elapsed exposure time will be 
displayed on the LCD panel.
F: Bulb Exposures
Elapsed exposure time
  Long exposures produce  more noise than usual.
  If Auto ISO is set, the ISO  speed will be ISO 400 (p.122).
 When [z 4: Long exp. noise reduction] is set to [ Auto] or [Enable ], 
noise generated by the long ex posure can be reduced (p.143).
  For bulb exposures, using a tripod and a remote switch (sold separately, 
p.184) is recommended.
  You can also use a remote  controller (sold separately, p.184) for bulb 
exposures. When you press  the remote controller’s transmit button, the 
bulb exposure will star t immediately or 2 sec.  later. Press the button 
again to stop the bulb exposure.

Highlight detail and shadow detail are retained for a high dynamic range 
of tones even with high-contrast scenes. HDR shooting is effective for 
landscape and still-life shots.
With HDR shooting, three images of different exposures (standard 
exposure, underexposure, and ov erexposure) are captured for 
each shot and then merged together automatically. The HDR 
image is recorded as a JPEG image.
* HDR stands for High Dynamic Range.
1Select [HDR Mode].
  Under the [ z4] tab, select [HDR 
Mode ], then press < 0>.
2Set [Adjust dyn range].
  Select the desired dynamic range 
setting, then press < 0>.
  Selecting [ Auto] will have the 
dynamic range set automatically 
depending on the image’s overall 
tonal range.
  The higher the number, the wider the 
dynamic range will be.
  To exit HDR shooting, select [ Disable 
HDR ].
w: HDR (High Dynamic Range) ShootingN
 Only the merged HDR imag e will be saved. The three images used to 
produce the merged HDR im age will not be saved.
  You cannot select RAW and RAW+JP EG. The HDR mode cannot be set 
if RAW or RAW+JPEG is set.
  If you set AEB, white balance bracke ting, Multi Shot Noise Reduction, 
multiple exposures or if you shoo t bulb exposures or a movie, HDR 
mode cannot be set.
  The flash will not fire  during HDR shooting.

viewfinder shooting and Live View 
shooting.

  When you press the shutter button 
completely, three consecutive images 
will be captured, and the HDR image 
will be recorded to the card.

 If you shoot a moving subject, th e subject’s movement may leave 
afterimages or the surrounding area  of the subject may become dark.
  To prevent camera shake, the ISO sp eed may be set higher than usual.
  HDR shooting is not possible with  ISO expansion. (HDR shooting is 
possible within the range  of ISO 100 - ISO 12800.)
  When shooting HDR images with [ Auto Image Align] set to [Enable], 
AF point display informat ion (p.294) and Dust Dele te Data (p.341) will 
not be appended to the image.
  If [Auto Image Align ] is set to [Enable] and the HDR picture is shot 
handheld, the edges of the photos  will be cropped, lowering the 
resolution slightly. Also,  if the images cannot be aligned properly due to 
camera shake, etc., auto image alignm ent may not take effect. Note that 
when shooting with excessively bright or dark exposure settings, auto 
image alignment may  not work properly.
  If you perform handheld  HDR shooting while [Auto Image Align] is set 
to [ Disable ], the 3 images may not be pr operly aligned and the HDR 
effect may be minimal. In such a  case, using a tripod is recommended.
  Auto image alignment may not work properly with repetitive patterns 
(lattice, stripes, etc.) or  flat, single-tone images.
  The color gradation of the sky or  white walls may not be reproduced 
correctly. Irregular colors or nois e may appear.
  HDR shooting under fluorescent or LED lighting ma y result in unnatural 
color reproduction of  the illuminated areas.
  Since HDR shooting merges the images , it will take a longer time to 
record the HDR image to the card than  with normal shooting. During the 
processing of the images, “ buSY” will be displayed in the viewfinder and 
on the LCD panel and you cannot  take another picture until the 
processing is completed.
  In HDR mode, the options grayed out in  the camera menu cannot be set. 
Note that when you set  HDR mode, the Auto Lighti ng Optimizer, highlight 
tone priority, and exposure  simulation will be set to [Disable] before 
shooting.

You can shoot two to nine exposures to be merged into one image. If 
you shoot multiple-exposure images with Live View shooting (p.215), 
you can see how the single exposures merge while shooting.

 During continuous shooting, the  continuous shooting speed will 
decrease greatly.
  If you set white balance bracketing,  Multi Shot Noise Reduction, the HDR 
mode or if you sh oot a movie, multiple-exposure shooting cannot be set.
  If the Wi-Fi function is used, multip le-exposure shooting cannot be set.
  During multiple-exposure shooting, Auto Lighting Optimizer, highlight 
tone priority, peripheral  illumination correction  and chromatic aberration 
correction will be disabled.

noise reduction and color space, etc. se t for the first single exposure will 
also be set for the subsequent exposures.
  If the Picture Style is [ Auto], the [ Standard ] Picture Style will be set for

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 exposure compensation. 
Refer to the basic guide below to set a negative exposure 
compensation.
Exposure Compensation Setting Guide for Multiple Exposures
Two exposures: -1 stop, three expos ures: -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.
4Set the [No. of exposures].
  Press the < V> key to select the 
number of exposures, then press 
< 0 >.
  You can set it from 2 to 9 exposures.
If [Additive ] is set, the image displayed duri ng shooting may look noisy. 
However, when you finish  shooting the set number of exposures, noise 
reduction will be applied and the fina l multiple-exposure image will look 
less noisy.

 Only the merged multiple-exposure  image will be saved. The images 
taken in steps 6 and 7 for the multip le-exposure image will not be saved.
  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 [ Additive] is set, the Live View 
function will stop automatically when  the multiple-exposure shooting 
ends.
  In step 7, 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 the power switch is set to < 2>, the battery is re placed, or if you 
switch to movie shooting after yo u set multiple exposure settings, 
multiple-exposure shooti ng will be canceled.
  If you switch the shooting mo de to a Basic Zone mode or < w> while 
shooting, multiple-expos ure shooting will end.
  When multiple exposure  is set or while you shoot multiple exposures, 
you cannot use the functions grayed out in the camera menu.
  If you connect the  camera to a computer or  printer, multiple-exposure 
shooting is not possible.

Merging Multiple Exposures with an Image Recorded on the Card
