Just had my first play with X10 RAW in LR3

Close up shots of my old cat (lots of fine texture) under room light - shot JPEG + RAW.
X10 went for 1/25s, ISO 800, DR400.
Comments based on pixel peeping in LR3.
There is lots of good news
Dynamic Range...
I lifted the shadows 2.5 stops before noise and false colours started to become intrusive amongst the shadow detail.
I recovered 2 stops of detail from the highlights.
That's pretty blimmin good for ISO 800!
Also important (to me), the noise is far more natural looking - yay

I'm already using the post-processing friendly JPEG settings I found in another forum which are noticeably better than the factory settings at ISO 800. This a definite plus for using RAW.
Another observation that is quite striking is that the colours are different!
Several threads elsewhere on the web have commented that the reds can look a little odd sometimes; reds have been reported looking pink, whereas I've seen pink looking red. The reds in LR3 RAWare hugely different and far more subtle. The blues are slightly different, but nothing like the reds; I've no green in my scene.
Also, it's not just the full-on colours, the deep shadows have colour in X10 JPEG but fade to black in the LR3 RAW.
In summary, the RAW colours are flatter but may prove more life-like.
Something that makes comparison quite difficult - I can't reproduce the DR400 look in LR3!
I think the DR400 JPEG has been constructed using light tone mapping.
There is no way whole image modifications in LR3 can achieve the same result.
It's a lot of work in LR3 to get a RAW image looking as rich in texture as the JPEG straight out the camera.
That's a big plus for X10 JPEG! I think this indicates that taking RAW + JPEG is the way forward; RAW for the ultimate original plus the JPEG to show how much rich texture is available within the tones.
Finally - there are very different algorithms at work at the pixel level.
In one of the shots is part of my monitor, the pixel structure is slightly out of focus. The X10 JPEG clearly shows the pixel matrix as slanted vertical lines. LR3 RAW shows these no where as clearly (phasing in and out), but the weird thing is that the actual display content (star ratings in the LR3 bottom bar) look far more like stars in LR3 RAW than the X10 JPEG. Just for perspective, the screen is slightly out of focus and I'm looking at 100%; it's quite subjective and both are acceptable.
I have a slightly out of focus cable with writing on the side deep in the image shadows. The text is narrower than the noise structure at ISO 800. The LR3 text looks crisp compared to the X10 JPEG!
Again - a reminder - both renditions are actually pretty good - but I prefer the LR3 RAW as it seems to bring out the 'real' detail.
These findings are only indicative of my initial testing in low light.
I've not enough time to illustrate my points with images; but if there is enough demand I'll come back to it.
As always - use my opinions as a guide on what to look for, but do your own tests and make your own conclusions
I'm really looking to forward to seeing what LR3 RAW can do with a decent landscape image
