Operating the H Cameras for Digital and Film Photography 79
NEW OPTIONS ON H3DII CAMERA MODELS
What used to be called the Drive control is now the ISO/WB (white balance) control. The Drive
settings are now made by pressing the Menu control and turning the front control wheel to
DRIVE. Press the ISO/WB button and turn the front wheel to SINGLE or CONTINUOUES MODE.
(Multi Exposure is also available but only on H3D models with a fi lm magazine attached.) Save
by pressing the ISO/WB control.
ISO and White Balance Control
The ISO and White balance settings can be set and changed either on the sensor unit or on
the power grip of the camera since the ISO/WB control on the latest H3DII cameras gives
immediate access to the ISO and White Balance settings. Depress what used to be called the
Drive control (this is marked on the new cameras as ISO/WB control). Set or change the ISO
value with the front control wheel. The setting is from 50 to 400 ISO on the 22 and 39 Mpixel
models, from 50 to 800 ISO on the 31 Mpixel models.
Set or change the White Balance setting by turning the rear wheel to Daylight, Shade,
Cloudy Flash, Fluorescent, or Tungsten. You can also make your own color temperature set-
ting from 2000 to 10,000 K by pressing the AF button and then turning the rear wheel to the
desired color temperature values.
Press the ISO/WB button to save the settings. The settings appear on the sensor unit only
after they have been saved. The set color temperature is used only for viewing. The raw for-
mat fi le contains all the information for correction with the software regardless of the color
temperature at the time of exposure.
The H3DII Mirror Delay Option
Tests have shown that a slight delay between the moment the mirror settles in its lifted posi-
tion and the time the exposure is actually made can improve image sharpness in many cases
in handheld photography, especially when somewhat longer shutter speeds are used. The
same applies at any shutter speed when working from a tripod. All H3DII cameras allow you
to change and set this delay time to 25, 50, 100, and 200 milliseconds (Figure 4-26).
While these delays are very short (milliseconds), it is highly recommended you take
advantage of this new option. It will help create the sharpest images in digital or fi lm photog-
raphy. This new option is not meant to eliminate the suggested approach of pre-releasing the
camera. Pre-releasing is still the best approach for eliminating camera motion, but it is often
not practical and, of course, completely impossible in handheld photography. Since possible
camera motion in handheld or tripod work is determined by numerous factors, it is impos-
sible to suggest a recommended delay time, but a 50 millisecond setting, which is the default
setting, is a good starting point. Longer delay times should be considered with longer focal
length lenses.
The extra mirror delay time is set either by loading the standard profi le or by making a
manual change in the custom options. The mirror delay option was added to the H3DII cam-
era models even though the operation of these cameras is extremely smooth because the
