Greetings Again Marc,
I will have to agree with you about the generalization that higher grain &/or noise with the higher iso's in cameras or in films can be a real detriment to 'absolute' image quality, but there are always trade offs of one kind or another in the creation of a great image and one must be careful of the images one denies oneself the potential to create with blanket condemnations of higher iso's and higher speed films. Coming from my own creative perspectives and imaging interests, trading away billboard print sizes or grain free images for the ability to reach into places and moments and situations that I wouldn't otherwise be able to explore photographically is simply one of the trade offs inherent to photography as a craft. I will also say that the sensor size tradeoff inherent to the digilux family of cameras means that the noise at higher iso's is much much worse than the bigger sensors in the dSLR families. The imaging benefits of bigger negs from before have come home to roost in the imaging sensors of today - the technology and physics for it being true vary a little from film to digital, but the axiom holds fairly well nonetheless. Now having said that! While I am fairly comfortable pushing the iso up in my dSLR, I would probably avoid it at all costs in a camera with a sensor smaller than the 1.5/1.6 family of dSLR chips. The color noise and random image noise in general is almost unbearable to me!
Well, at least shooting long-time exposures seem easier with those, even at lower ISO

Hello Richard,
Since I "discovered" the RAW file, and its possibilities, I don't use no more the JPG ones. 
So, I supposed at high ISO, JPG would be even worse than RAW.
I generally don't use high ISO, because the typical grain of films, and noise in digital files. 
So, I'm very grateful with this information.
I've to try again, from these same RAW files, and noise reduction tools !
Thank you so much, Richard.
Marc

    Hello Marc,
       I can't speak specifically to your d3, but generally speaking
    some variation of software noise reduction is applied to the jpegs
    when shooting these smaller cameras at higher iso's that wouldn't
    be applied to the RAW files. You would have to experiment to
    confirm this for your specific camera, obviously. The upside of
    this is that when processing the RAW file you can choose whether
    to noise reduce the image or not and you can reach for a range of
    noise reduction filters on the market for Photoshop and other
    programs and fine tune how much or how little mucking around the
    image they do in order to get the job done. The in camera
    algorythyms can sometimes get a bit brutal, which is generally
effective, but it can't know whether it needs a little or a lot. 
    Richard

    Salut Philippe,
    Thank you so much, amigo. If you want, I can send you some
    music from them.
    About the high ISO, I've to say the JPG file is cleaner than the
    RAW one (with more noise).
    I just realized it after upload the 3 first pictures :-(
