I've been asked in one comment to see the difference between RAW and jpg images for the Panasonic DMC FX150.
I've used Raw Photo Processor on OS X to get the data out of the rw2 file. The only adjustment I made was to change the white balance from "Auto" to "As Shot". By doing that, it's made the colours more vivid, but still not as vivid as the in-camera jpg conversion did.
I took the Panasonic DMC FX-150 camera on our honeymoon out in Nevada and California. It was an ideal size, quick to start and produces serviceable images. To manage them, I used Picasa since we only had my wife's old laptop with us and it could just about run Picasa. I was quite happy applying quick edits (e.g. adjusting the white balance, shadows and highlights) knowing that I had the raw files to play with back home (ok, I was wrong). Plus I didn't really want to spend any time doing it, so quick edits were the order of the day.
