Dual Slot Memory Cards - Canon EOS1 Ds MARKII Design And Performance

Dual Slot Memory Cards

White Balance is indicated on the rear LCD panel. There
are ten separate settings: Auto (approx. 3000-7000K),
Daylight (approx. 5200K), Shade (approx. 7000K), Cloudy
(approx. 6000K), Tungsten light (approx. 3200K),
Fluorescent (approx. 4000K), Flash (approx. 6000K),
Manual (from 2000-10000K), Color temperature (approx.
2800-10,000K) and PC-1 to PC-3, allowing registration of
up to three color temperatures with dedicated software.
The accuracy of the new white balance algorithm, especially at low color temperatures,
has made it possible to eliminate the external AWB sensor found on the 1Ds and to
discontinue hybrid AWB.
The white balance compensation function allows users to adjust the currently set
white balance mode's standard color temperature (between 2000 and 10000K rather
than from 2800 on the 1Ds). It provides the same effect as attaching a color
conversion light balancing filter (for corrections in the blue-to-amber range) and/or a
color compensation filter (for corrections in the magenta-to-green range). The
compensation can be set up to 9 levels in single-level increments for each color. The
blue/amber bias and magenta/ green bias adjustments can be set in combination
with each other. Unlike conventional filters, the built-in white balance compensation
never fades and cannot be scratched.
White balance bracketing, shared with the 1D Mark II, permits three white balance-
bracketed images to be captured with a single shot, rather than the three shots required
on the 1D/1Ds. Magenta/standard color temp/green bracketing is added to the
blue/standard color temp/amber bracketing on the 1D/1Ds. Bracketing can be up to
+/-3 levels of blue/amber or magenta/green. White balance bracketing can be set in
combination with white balance compensation and AEB.
Rather than being set in a menu window, manually adjusted color temperatures can now
be entered directly in the Color Temperature selection mode using the WB button and
the main dial. This is easier than on the 1Ds and is more likely to prevent errors.

The same file can be recorded on each card, creating a full backup. If one of the cards
be comes full, the user can cancel the backup mode and continue shooting on the
remaining card.
III. NEW AND IMPROVED DESIGN FEATURES
The EOS-1Ds Mark II and the 1D Mark II have two card
slots, one for CompactFlash and another for the
physically smaller Secure Digital. Canon engineers were
able to make this addition without altering the legendary
"1 series" chassis. There are several ways to take
advantage of this configuration:
