Re: gross photography setups
|From:||Roger Moretz <email@example.com>|
A couple of comments. IF you have the budget, look at
the digital cameras that utilize the IEEE 1344
(Firewire) connections. We have a SONY 1350 (I think
that's the model--not near any of it right now) and
the data transfer is nearly instantaneous. The macro
mode of the lens permits gross photography without
adaptors. The camera has a white balance mode that
permits use of fluorescent room light with minimal
tonal distortion. What we miss most is a right angle
adaptor for the view lens, but the LCD can be used,
even in bright room light. Sony uses what they call a
memorystick rather than Smartmedia or CompactFlash
cards (and they aren't cheap).
NIH Image is available from Scion Corporation
http://www.scioncorp.com -- free to academic
institutions, but for a fee to commercial enterprises.
You also need to consider what you will use for your
image database (your digital image files). There are
a number of commercial programs available, some of
which are quite reasonable. Think about what you need
to have (in terms of information to identify each
image) and make sure any program is flexible enough to
meet your needs. If you want to _really_ get thorough
about ensuring your data's integrity, check the FDA's
regulations for validation, etc. Yeesh! We are using
ImageCentral from Advanced Imaging (Princeton,
NJ)--not a plug--just a comment. I use ULead's
product at home, and it is adequate for my personal
needs. I am having a Medicare moment on the names of
As far as CD vs DVD--DVD writers are very expensive,
and the media isn't all that cheap. And, if you are
following the type of archiving required under Chapter
11 (for FDA), each data disk has to have at least two
(and maybe 3--another Medicare moment here) copies
made. So, for now, CDs are probably the way to go.
Also, even the newest digital cameras (including our
Sony) are only about 3MB images, so a 700MB CD will
hold a fair number of images. If you use Adaptec's
Easy CD Creator software, you can start a disc with a
few images and add to the CD (up to capacity, of
course) as you go along.
Enough rambling. Hope this helps.
NB All opinions expressed are my own. I have no
financial interest in any of the companies
mentioned--I only mentioned them because I use the
products and find them satisfactory.
