Color accuracy?

    I've a Kodak DX6340, recently noticed that some colors are not
    reproduced accurately. A deep blue/almost purple flower I was
    taking a close up of did not appear in the digital viewfinder
    to be the correct color, nor the finished image as displayed
    on my PC screen. It appears lighter than the real thing.
    I don't know if this is typical for this type of camera
    of if the sensor is aging? Camera is 4 yrs old and has been
    used quite a bit. Do the sensors degrade over time especially
    if exposed to bright sunlight? Thanks

    Doesn't seem likely that the sensor has degraded. It's easy to imagine a
    camera having difficulty metering an exposure properly on something of
    that color, though. You might try a different metering mode or try
    bracketing. Don't expect center-weighted or spot metering to get it
    right. If you have manual exposure controls, try setting the exposure
    for stuff in the background.

    Ron,

    The only options for metering light are multi-pattern, center-weighted
    and spot metering. The camera was set to multi-pattern when I took the
    image of the flower. What is bracketing? Also, how would I set
    exposure "for stuff in the background", assuming this camera has that
    capability? Lastly, would it have made any difference in color
    accuracy, had I taken the picture in a setting other than "Close-Up Mode"?
    Thanks very much for your reply.

    Mike,
    Multi-pattern would be the best of those 3 choices. If you don't have
    manual exposure control, you might be stuck. Bracketing consists of
    taking additional exposures at settings like 1 f-stop higher and 1
    f-stop lower to increase the chances of getting a good shot. Some
    cameras can do this automatically. If you can adjust EV (exposure
    value), that might also help. Close-Up Mode wouldn't likely affect the
    exposure. On the other hand, if you took the picture from farther away,
    metering might do better. You could crop the image later.

    Ron,

    The camera does allow aperture priority settings, so next time I will
    try the 1 f-stop higher lower idea. It also does (I think) have EV
    which lets you choose from -2 to +2. I'm not sure, but I think changing
    those values changes both f-stop and shutter speed automatically.
    What exactly do u mean by manual exposure control? Wouldn't that
    be a combination of f-stop, shutter speed and ISO settings?
    I can adjust all of those to some extent, but not for just
    the background of a close up shot.
    Thanks again for all your help. It's much appreciated.

    Hi Fellows. new guy here - Harvey -I use a Panosonic Lumix FZ3 - a
    fixed lense digital with lots of settings - I have started using the
    bracketing mod +1.5 - & -1.5 for most all of my "Specila" shots that
    along with photoshop seems to get most all I could ever want from my
    photos.
    I even recently shot the full moon and got my first decent shot.
    spot light metering mode
    spot focuseing
    -2 steps on light
    the camera took the photo at F2.8 at 1/25

    Harvey in the California Sierras about 75 mi South of Lake Tahoe.

    In manual control, you set the ISO, shutter speed, and aperture
    yourself, hopefully with the help of an internal or external light
    meter. Most non-SLR digital cameras don't have that capability. Sounds
    like you can change EV, so you might not need it.
