For low light bird shooting I used high speed negative film. At least
that way I could keep some detail on white birds.

Nothing. You only need to frame and shoot. The major adantages using
RAW are you can do EVERYTHING afterwards, without messing with all
that stuff in the field. Let's see, white balance, complete colour
balancing, levels, curves, saturation, sharpness, exposure
compensation, contrast adjustment, and many other things can be done.

If you shoot JPG, the camera applies your parameters immediately to
the file it saves. There is no changing it. There are four parameters,
sharpness, contrast, saturation and colour tone. White balance is also
set in the JPG. Exposure is set of course. If you shoot JPG in Adobe
RGB the four parameters can't be used. You can save three custom
parameter sets, and you can do a manual white balance in the field
from a white paper sheet or grey card. Plus you can choose from many
manual WB presets. If this all sounds like too much, then you
understand why I shoot RAW. I much prefer to tweak my images quickly
and easily in the computer. That leaves me to concentrate on my
subjects, focus, and exposure. Evaluative metering seems to be doing
the best job for me, but I do tweak it up and down a bit while
shooting of course.

Now, having said that, the 10D does a great job in auto white balance
and all the other stuff in most average shooting scenes. I just don't
end up shooting much in average conditions :-)

On the matter of storage space, RAW ends up not actually taking much
more space. The reason is because I don't have to keep large TIF
files. Capture One LE remembers my settings so I can easily convert
later if I need a TIF again. If I do extra Photoshop work on an image
I of course do save a TIF. I also do save small JPGs of each image,
but the thumbnails are actually enough to tell which image is which. I
do save alot of clutter too without all the different file types, I
only backup the RAW and THM files.

Workflow is simple and fast converting RAW files. I adjust the
exposure and contrast, colour balance it, and tweak the sharpness.
Takes me about a minute for each image. And I can apply settings to
other RAW files with a click. This really helps when you've got a
bunch shot in the same lighting. There are of course many other
options and tweaks for special images and conditions but they're
usually not needed.

I think people who shoot JPG are those who have tried using Canon's
Fileviewer for conversion of RAW files and gave up. It takes forever
and just can't do the same job. Capture One LE gives me an instant
preview of any changes, in a colour correct space, in a zoomable
preview, etc etc etc.
