Digital BW, The Print

Hi Clayton:
I agree with your comment about wanting to check daily shoots in the evening 
(and making backup copies is even more important). A portable CD writer or 
hard drive like the Epson P2000 is very useful.
However, the batteries in the "big" Canons (1Ds and 1D)  are very different 
from those in the "prosumer" models. I have a Canon 10D and a 1 mark II. The 
10D with its BP-511 will give me a couple of hundred images before pooping 
out; the 1 mark II with its NP-E3 has given me more than 2000 and still 
showed full charge. I've never had to change one during several days' shoot. 
It is also a significant contributor to the much greater size and weight of 
the 1 series digital bodies and I would guess, about 4-5 times the size 
(volume) of the 511.
Unfortunately, the battery in the Epson P2000 is even smaller than the 
BP-511, so a whole set of them would be needed for a week without access to 
charging.

Hello Steve,

>The Canon 1DsII batteries will last through that time easily...

My Canon uses the BP-511a at 1390 mha.  I think the idsII uses the
same or similar battery, as do many of the Canon DSLRs.  It is indeed
a good quality battery.  However, regardless of which battery is used
in a given camera, my experience has shown that how long a battery
lasts is directly related to how many pictures one takes and how much
the view screen is used.  I don't think it is a stretch to suggest
that more than one charge would be required during a week of busy
shooting during a photo expedition, especially in such an image rich
area as the High Sierras.

I imagine it would also be very tempting to want to review each day's
work.  Even if all viewing is done on an off-load storage device,
batteries are required for that.  I would consider it sheer folly to
pay travel expenses and workshop fees for a relatively rare and
week-long opportunity like that and only take one or even two
batteries for whatever devices are used.

Regards,
Clayton
