Notable granularity when taking indoor photos using Fuji FinePix S5100

    Hi all,

    I have Fuji FinePix S5100.

    I have taken lots of indoor photos.

    I have tried all sort of ISO levels, compression, white balance,
    shooting modes and still had the problem.

    Only lately I have found a workaround to the problem.

    It appears that if I use very low ISO (64) & high compression (1 MP) I
    can get sharp indoor photos.

    Yet the photos are 1600x1200 (1.8 MP) and I would expect more from 4 MP
    camera.

    I wonder - is it a model problem or is it a defect in my camera?

    Any help from other Fuji users?

    Thanks in advance,
    Bill.

    Seems to me you may be confusing compression with resolution above.
    Resolution is the number of pixels in an image. Compression relates to how
    the information is stored and the resulting file size.
    I'm not familiar with this camera, but I would think there are separate
    controls for setting Quality/Compression and image size/resolution.

    So far you haven't said what it is you're attempting to do, nor
    what the problem is.

    I'm not sure what you mean by "MP" here. The table on page 24 of
    the S5100's manual indicates that the 1 M setting represents a
    resolution of 1280 x 960. This is about 1 megapixels. Is that what
    you meant by 1 MP? The 1600 x 1200 setting (2 M in the manual's
    table) is about 2 megapixels.
    This I don't understand. You seem to be saying that when you take
    pictures using ISO 64 and the 1 MP setting (1280 x 960), the indoor
    pictures it produces are sharp, but the pictures somehow end up
    being 1600 x 1200. What is the "more" that you are expecting? The
    table shows that a 512 MB card can hold 268 or 532 2072x1704, 4M
    pictures (depending on whether you select compression corresponding
    to F or N). The same card can hold 818 1600x1200, 2M pictures or
    1,101 1280x960 1M pictures. The higher the resolution, the sharper
    the pictures should be. Are you getting different results? You seem
    to be saying that you can take low resolution pictures, and they're
    sharp, but you still expect "more" of something because the S5100 is
    a 4 mp camera.

    I might be able to help, but I don't really know what the problem
    is yet.

    Ed, this camera several choices for resolution, but only the
    highest (4mp) offers a choice of compression ratios. I'm not sure,
    but I think that Bill's "granularity" problem might be related to
    insufficient light when taking indoor pictures. But nothing was
    mentioned about whether or not flash was used, whether warnings
    appeared in the display, etc., so I don't know . . .

    I have the same camera: and haven't noticed this problem. (At least no
    more so than any other digital camera I've ever used...) The only
    images that get noisy for me are ones taken in VERY low light situations
    sauch as nighttime long exposures.

    However, I did have to play around with it quite a bit before I got it
    right. The SIZE of the image shouldn't matter, but, yes, a lower ISO is
    better when you're shooting in lower light situations. There is a
    noticeable reduction in noise with the lower ISO...just play and
    experiment...you'll get it.

    So far, I'm impressed with this camera...

    Thanks for the response,

    You are right about the resolution - the 1 MP resolution produce 1280 x
    960 photos.

    This is the resolution I get the best indoor photos.

    By best I mean - sharp in the photo actual size (100%).

    I think that the reason is that somehow the CCD granularity is less
    notable in low resolution - still I can't explain this.

    The photos in the 1MP resoulution looks sharp as regular SLR photos
    while the 4MP/Fine photos looks blur and noisy.

    In general - the 4MP photos looks less focused.

    That's can not be the blame of the focus since in 1MP the photos are
    sharp.

    I take the photos under indoor light and not in complete darkness.

    Regards,
    Bill

    Thank's for the response,

    I have tried the shutter priority with much higher speed (1000) and got
    much better results.

    The blur is gone and the image is much more sharp then the one taken
    with the regular shutter speed (60).

    If you have any particular good setup for shhoting kids, I will be
    happy to know.

    Regards,
    Bill

    It it's not the focus that's to blame then there's something wrong
    with your camera. You could try testing this in a way similar to
    what I did. I took pictures of several columns of books stacked up
    one on top of the other. Standing to the side, so that when focused
    on the center column, the column of books to the right is closer to
    the camera and the column to the left is further away, this allows
    you to tell when looking at the finest text characters in the image
    where the lens was actually focused.

    I used the same ISO 64 setting and took pictures with and without
    flash. The ones without flash were underexposed and a little harder
    to compare, but it was apparent in all of the shots that the 4mp
    pictures had far more detail than the 1 mp pictures, and all were
    well focused. I didn't notice any noise in the pictures, but then
    the ones I took weren't of subjects that really make noise stand
    out.

    One thing to check is whether the AF is working properly. The
    lens's zoom setting can effect how it focuses. In some cases, such
    as when objects are too close, you might have to enable macro mode,
    even if the distance to the subject is 4 or 5 feet. Normal,
    non-macro mode is supposedly good down to 3 feet, but macro mode is
    effective up to 6.6 feet (2 meters). In the distances where the
    modes overlap, from 3 to 6.6 feet, you may find that the camera
    focuses more accurately when macro mode is used. It's very easy to
    enable since the camera's menu isn't used, and you get a nice, clear
    confirmation in the display.

    Remember to lead them a little and take the wind speed into account.

    Also allow for the drop (aim slightly higher).

    S7000 is very grainy too

    Ive notived this from the very start.. Have been comparing images of a few camera and I feel its the CCD.

    Compared to Nikon, or even a Kodak the S7000 super CCD is not as super as they claim. I will keep trying a few things but feel the effort will be futile.

    cheers
