to me the key would be backups -- is there a small device available that
will duplicate SD cards? alternatively a sat-data link to cloud storage,
but i bet that would cost more
One reason I asked for generic solutions rather than specific items is
I'm hoping to figure out how to do as much as possible using my existing
kit ...
But this does bring up an interesting tangent. Do I misremember that the
645D has TWO SD card slots?
If so, can it write to both cards simultaneously? Instant backup?
Can it copy the contents of one card to another card?
The 645D is not really in my future I think, despite that I truly do
lust after it. I'm afraid it will always remain one of the unfulfilled
items on my bucket list.
OTOH, many of the "Netbook" computers have built in "multi-media"
readers that will take an SD card. I see no reason they couldn't write
to one as well.
One drawback of that is the camera will probably not display the images
written to the card by the computer. During my internship, I tried
something similar with the K10D. I had no thumb drive with me when I
needed to transfer a JPEG from my laptop to another computer. Both have
built in card readers.
I copied the JPEG to the spare SDHC from the battery grip. The JPEG in
question was originally taken with the K10D, but I had to correct
something with Photoshop (replace closed eyes).
On a lark I put that card into the camera after making the transfer. It
would display the other images on the card taken with the K10D before I
copied the JPEG. It would even display images I took after writing to
the card with the computer, but it would not display the one image
written to the card by the computer.
In any case, it would probably make more sense just to download the card
to the internal drive & back it up to something like the LaCie drive I
already have. A 200GB USB drive is the same capacity as 25 8GB SDHC cards.
If I need to review the images, I could just use the Netbook.
On my recent trip to China, I carried the K20D with the K10D as backup.
I have battery grips on both, along with one spare battery ... chargers,
lenses, etc.
I carried 6 - 8GB SDHC & 10 - 4GB SDHC and a Mac formatted 250GB LaCie
USB drive [1].
I had a commitment from several of my traveling companions to allow me
to use their Macs if I needed to download the memory cards. I never
needed to. I was still quite debilitated from my recent surgery, far
sicker that I realized at the time, and I didn't shoot enough to use the
full capacity of the 8GB cards I had with me. Although, at least part of
that was I deliberately slowed my pace to accommodate a style necessary
to shoot film with the LX.
I expect that had I been in better health I would have been more active
as a photographer.
[1] I installed MacDrive on my laptop so I can read the Mac formatted
LaCie drive. Seemed to be the simplest solution to some other problems I
had synchronizing schoolwork between my own Windoze computers and the
school's Mac systems.
