Well, I've completed the LEGO-related portion of it. The project also
involves studying some captive woodlouse cultures and quite a bit of
field work (examining local population distribution, etc)...I have about
50 or so more pages to write in hmm...*looks at clock* about 3 weeks ;)

Those two photos in my driveway are the first two I've done where I
didn't do any substantial image processing. Most of the other photos on
the site were taken outdoors, on a white backdrop (typing paper spread
out on my front porch). I take the photos when it's bright and sunny
out, but place the bots in the shade. Once I get the photos in the
computer, I begin the long, irritating process of tweaking the contrast
and erasing all of the shadow artifacts etc.

But there is a loss from the camera's CCD to the file write. Irritating
that they do this sort of thing just so they can market the camera as
having a higher maximum capacity than it would otherwise have using a
raw format. My S20 has has three compression levels: Crappy, Normal and
'Superfine', and I have yet to see any quality increase between Normal
and Superfine. They seem to have exactly the same amount of JPEG
artifacts, yet the file size is about four times larger in Superfine mode.
