    I know I don't have a good eye and like to listen to the comments to try to improve my images the best my equipment would allow. But when you are told you have too much noise in a shot that was taken at iso 100 in the middle of the day.Had me think like you that there is a problem with more than my cheap glass.
    Thanks

    I see the noise mostly on the sky. They are rather monochromatic so it's not as distracting unless you point it out. Not sure if the A100 can go below ISO200, but try lowest ISO possible.

    Unless less terribly mis-stated ... the A100, has a bottom floor of ISO-100 and a top stop of ISO-1600. The 1600 is a bit noisy on the CCD, which was corrected and enhanced to ISO-6400 on the A700.

    Anyway ... off to the Ikebana International Flower show, armed with both MACROs (90 & 180) and the 17-50mm. Outside, it's sunny and more direct than usual, today. Have a great last day of May, folks.

    Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.

    Red face shooting from the hip

    This first one is straight from the A700, other than resizing ... no post processing, no crop ... as is.

    @ 180mm - f/6.7 - 1/500 - ISO-100 - Manual - Direct sunlight/outdoors

    These next two, do to lighting issues, are a little more groomed.

    I'm kind of in a hurry, so the others will have to wait until I get back from the party.

    I figure this is a real nice start for something ...

    Smile Ikebana Flower Show

    Some of the blooms weren't ready ... and considering they had to last all weekend ... what the heck, right?

    The explosion of color was fascinating, though.

    This arrangement seemed ... amazingly directive, in a simple way.

    There was this one:

    Which I know you all were instantly thinking, "Doggone, Don ... that would make a great border sequence!"

    Voila! . . . . . . . . . . . . . . . then, "Posterized edges"

    Well, with a little more work on the merge, but Yeah ... you guys just might have something, there. Well, maybe not. LOL

    Party was okay, nothing mind bending. Thanks for looking.

    don, i think you need your eyes checked. frank is right, the images do have something in them. i dont think its noise though. looks more like some sort of artefacting possibly from the compression you are using. does this noise appear on the original aswell or is it just in the resized one ?

    the advice you go on the other forum is also correct. the more you fiddle with colour, saturation and particualrly sharpening, the more you degrade the IQ.

    the lens you use will have nothing to do with noise. i noticed you shot that at f5.6. why is that ? typically you would want to shoot that scene with a little more DOF. maybe f8 or f11.

    Look ... without a 100% pixel peep crop ... seeing these "bit problems" is a little tough. Rather than make a blanket statement, I would like a 800 x 600 (or something close) 100% crop to look at.

    Of course, these "one-of" shots are rather hard to criticize ... reproducability is at the heart of a noise issue. "Is it showing up in EVERY shot?" should be more of the focus when tracking it down.

    There are certain settings to stay away from ... that just have "noise" written all over them. It would be wise to note these particular settings ... and use them several times, under various lighting conditions and inspect the results.

    That's just my experience with it. Everyone needs some of their own.
