Digital P&S and color bit depth

    Curious about digital point and shoot still cameras along the lines of
    color qualities and color bit depth, my old Nikon 950 does a mere 24
    bits which is 8 bits per RG and B channel. Are there any P&S machines
    that go to at least 12/36 raw, or even better, to 14/42 raw?

    Reason I ask is, it's a rather huge endevour to search it out, and I think
    it is a good issue concerning higher-end P&S cameras that might be of
    a genuine artistic quality.

  2. The 8-bit is JPEG, which has a dynamic range approximately equal to 12-bit
    RAW, because of the gamma-correction included in the JPEG files and not
    the raw files. The compromise is that JPEG does not offer the same
    accuracy as RAW.

    Many non-SLR cameras offer 12-bit raw, I don't believe that any SLR or
    non-SLR offer 14-bit - yet. Check D P Review for the features of
    particular cameras - I think you can make a personalised comparison page
    but don't ask me how!

    That's what my Nikon 950 does. At 8/24 bit color depth.

    That question doesn't apply unless you would clearify. I am asking what cameras
    do give higher color bit depth than 8/24. Something to upgrade to, over the very
    old 950 ('99).

    You are a woodworker on the Albion, yes? I studied your pages a lot, especially
    using the link page for workbenches, a great help.

    Huge endeavor? Give us a break. Use the feature search engine at
    dpreview and choose Raw uncompressed format.

    chuckle chuckle
    Thanks, tried that but nothing gave any indication of "actual" color bit depth...
    or is it that simply "raw" means it will be a higher level, 12/36 no matter what?

  6. No pathetic, you can't be bothered to even click on a few links
    What's the "?" link for next to each line on the comparison page. god helps
    those who help themselves. Of try a google search on dpreview article raw.
    I'm not going to spoon feed you just because you're too lazy to look around
    for yourself. This is basic info.

    Today you're more Edward Gruf than Ed Ruf. I haven't checked the
    phase of the moon, but notice that I've also been a bit more snippy
    than usual that last day or two. :)

    For crying out loud WHAT a cold pile TURD this guy is! CRYPES!
    Personally type a lot to help people out all the time and I get this nasty
    attitude for nothing I did wrong to him!

    Hey DO NOT EVER reply to my posts again, because you have one SERIOUS
    problem that you cannot overcome as good as any normally mature adult that
    NEVER thought of it. And THAT is pathetic of YOU!

    So keep your icy stink to yourself. Because the only reasons to get into news
    groups is to give and recieve "help" - to and from "people".

    BTW, "God helps those that help themselves" is not part of the WORD of God,
    it is not in the Holy Bible. So that fantasy is not "the word of God".

    God helps those that ASK in FAITH to him. And that IS there, for those that
    accept him through CHRIST! You can prove it to yourself by clicking the link
    in my sig. It has a search engine, and many versions.

    I forgive you, I AM psychologically more powerful than you are, and you are
    not* plonked just so I can monitor you. Do not reply to me, anywhere.

    The ? just explains file sizes and compressed v uncompressed formats.
    Unfortunately this does not give the information asked for, bit depths. Or
    is there something I am missing? I'm a bit confused by this as it would
    seem to be desirable information to me.

    The page I found by searching appears to be a general comment on raw files,
    I suspect you cannot use it to make assumptions about certain cameras.
    Well, yes, as you have one sensor any a bayer colour mask. You must
    interpolate to fill in the gaps for each colour to get RGB.

  12. Thanks for that. I couldn't find that camera listed at D P Review. Do
    you happen to know how many bits the camera's ADC uses?

  13. ie http://www.dpreview.com/learn/?/key=compression
    Look at the top of the page, see
    Learn : Glossary : Digital Imaging : Compression
    all links and think a bit. Click Digital Imaging in the progression and
    what do you find? A table that directly leads one to:

    Yes I was grumpy. But the OP also happened to push a few specific buttons
    of mine in regard to posts we are getting from more and more visitors to
    this forum. First to quote "Reason I ask is, it's a rather huge endevour
    to search it out." No it's not and to pose as such implies one can't be
    bothered with simple searches. "Laughing off" this suggestion implies even
    worse, imo. Next, "Thanks, tried that but nothing gave any indication of
    "actual" color bit depth... or is it that simply "raw" means it will be a
    higher level, 12/36 no matter what?" So from my view the OP not only can't
    be bothered doing simple searches, but also can't even be bothered even
    giving us such minimal info as to what he's really looked at or tried
    looking at.

    Yes, I was dead, but I'm better now.

  15. Thanks for that - the M8 is a very nice-looking piece of kit, but the DMR
    would not suit me at all. Nothing on the ADC bit-depth, though.

    Interesting data sheet as well.

    Just a question about your mention of bokeh. Isn't that a
    function of the lens? Meaning, whether used on a digital or film
    camera, wouldn't the bokeh be the same?

  17. I believe that even in film the grains on the emulsion are not omnicolored.
    Sound like you are comparing 35mm film to P&S digitals, not dslrs.

  18. If you looked at the basic source of the signal in almost all accounts it
    is a 12 bit A/D converter.

  19. I believe you are confusing bit depth with dynamic range. Just what is a
    film D-SLR? Seems to be an oxymoron.

    Nope, nothing like that, if I might assume what AAvK meant by
    that. Their film SLRs are Fujifilm SLRs, and their DSLRs are
    Fujifilm DSLRs. If you look on Fuji product packaging, manuals and
    on their website, the company is actually FUJIFILM. From my P&S
    digital manual and brochure here's more than anyone but kinga needs:
