I first started with silkpix on the PC, but soon went the Lightroom
route when I got the Mac and have never departed from it.
LR could be the reason why the shift I presume then.

I didn't assume they were not present in the L1 raw, I think the
balance has to be restored one way or another, much less on the E400,
E510, and E620.
The "duplicate" JPEGs on the L1 look terrible and can hardly be
adjusted BTW. For the rest I still reget they never released an L2
with a higher pixel count, noiseless higher ISO capability, and a
better VF, that's all the faults I have ever found to it as a user's
camera over 5 years and so much ado about "technical breakthroughs".
