I did shoot these in RAW with no compression on the RAW. I use a batch
conversion macro in Lightroom (I think), and had it set up 640x480 size
with auto sharpen Landscape. I have never seen a jpg compression ratio,
I thought jpg just compressed it as much as possible. I also have never
used a batch conversion before, and never reduce the size so small, so I
really don't know if this is the result to expect or not.

Mr. Duck provided the explanation.

This is something that has annoyed me for quite a while now. You
would think that the camera manufacturers would get together and come
up with a standard RAW format that everybody could use at a base
level. Like open source software kind of thing. Each manufacturer
could add something of "theirs" for their specific camera, but you
could cross platforms if they got their act together.

If AOL hadn't of been pricks with their .GIF format, we would have
never seen .jpeg and all of it's attendent problems with handling RAW
output.
