Wow, that's really a new one on me! I didn't know about it. And
believe me, I've "borrowed" a LOT of on-screen jpegs from various
places in the last year. Is it something to do with the fact that
it's from a photo album site?

Anything else you see in the EXIF that might point to the culprit?
I am at work so I can't check it right now. All i know is that
image seems to have an inordinate amount of noise ... it reminds me
of pics I've seen from a Kodak DC4800!

Hi DrG

I sometimes get noise like this. I can shoot a pile of similar shots and a few will turn out noisy. I wonder whether at certain times the CCD is too hot. Say if a quite few of shots have been taken on the trot, in the sun or whatever... I note some of his shots show CA more than I see on mine.

Still it beats the poanst of the 6900 shots. And such noise is not a killer since it does not show in prints and in nay case is easily removed. If he shoots ORF, then there will be no noise atall added to some of the sharpening actions I have seen noise is history.

Make that four. That image looks amazing, especially the sky and there doesn't seem to be any, even slight loss of detail. Please, please share the action!!

Make that three calls for this action. Does it work in 5.5, or
just 6? Results look great, and I've just got finished manually
removing noise from 175 underexposed shots from a dance recital.
TIA.

I just uploaded it for you. There is noise if you REALLY look but nowhere near noise found in the sample you posted. It was shot in SHQ mode.

I can post other examples, even ISO 320 stuff if you are serious about the E10. I thought at first E10 was bad for noise, but that was only because I was reading too much here and mostly E10 bashing in other forums. It was not until I got my E10 a couple weeks ago that I realized that the noise is very controllable - it cleans up nice using noise-removal programs!

I think the guy that posted that sample shot in very low quality or re-sampled it down to lesser jpg quality. Image is rotated 90 degrees so that is evidence that there as some post-processing going on!

I found the link to this shot from an E-10 in another forum. Is
the amount of noise in this shot typical of the E-10 or does this
particular camera have problems?

I went back and took another look at your picture. Since there are no clouds present, the easiest way to rid the sky of noise would be to:
Open Photo in PS 6
Set magic wand to 12 or lower and select the blue portion of the sky
Ctrl C to copy the selected section
Create new layer
Ctrl V to paste selection in new layer
Highlight new layer
Select Filter / Gaussian Blur set at 4.0
Save new picture with noise free sky

Did I come close?

Thanks for all your interest and requests. Sorry, I had to go to bed before I saw them all. Please find this post for downloading it: "PS Noise action for those requesting." KV

I've tested umpteen PS noise reduction actions and found this one
to be outstanding. Not only does it not destroy detail, it's the
only one I've seen that actually appears to enhance it. I've used
it on many images with differing lighting, exposure, etc.
parameters and so far it works weill with all of them. Most
striking, of course is the blue sky. Again, though the image did
not start out with a great lot of noise. The action does a nice
job at what it's supposed to do, but none of them work miracles.
The photo was pretty darn smooth to begin with. Regards, KV

Not exactly. The PS action processes the ENTIRE image, not just the sky alone. Regards, KV

It's actually kind of hard to know how to respond to this. You say that you are very concerned about noise, that you cannot afford to make a mistake & you probable won't want to spend $$$$ on PS. If you are really finicky about noise & expect the camera to come out "buttery smooth" on every shot right out of the camera I think you might be disappointed. Perhaps you may wish to wait & see what the shots for the E20 look like - they should start coming out in a month.

The reason I say that, and if you read the other posts here, is that not all shots are going to come out of the camera noise free. Most that have noise have to be worked over, at least somewhat, in PS, especially if you are taking a lot of shots (such as outside) where you cannot control the lighting.

I love this camera. I have taken a lot of pictures with it. I do not regret having paid the money for it in the least. If I had $1,500 and had to buy a camera today it would be an E10. However, by the sounds of your concerns, I would suggest you wait for the E20 reviews & hear what the users have to say.

Kelly, anyone could take a fairly noisey img at 4mp and edge-preserve smooth it, then sharpen, then resize to half the original resolution and get these effects.

What kelly omits telling us all is that while it appears no detail was lost, half the resolution was lost.

Noise is inherently difficult to remove, even for big super computers, let alone the mini processor of a digicam, folks.

Jon, there's nothing to share except that it is more a fact that Kelly halved the resolution. That's why it looks so good. If the original res were up, it wouldn't be as noise-free.
 
Well Mr. Skeptical Chuilui,

Yes, the size of the file was reduced ONLY for the sake of easier access to it from the web page. I would be more than happy to put up the full-size 2.5Mb file if would satisfy your cynicism. Or you can believe me that the full size image (post PS noise reduction action) is just as noiseless as the 1600x1200 image that you see on the web page. I wouldn't take offense to your comments Chui except that you seem to imply that I did this intentionally to deceive. That I don't appreciate. I was simply wanting to share a good thing with my Friends on this forum. However, if you wish to make this an actual challenge I will be more than happy to put up the full res picture so that you can see for yourself. Just say so or otherwise leave your nay-saying to yourself. Are you on? Regards, Kelly

There's a lot of talk in this forum about photoshop - does anyone use anything else? I'm a web developer and I know that designers swear by the product but for photographers there are other products! Anyone have any experience with Picture Window (developed by the guy that produced lotus 123 and very cheap!) - see http://www.normankoren.com for for advice and details.

No great surprise, this troll (Chuilui) has left a BOGUS e-mail address, just joined the forum today and has a total of 2 posts. I sent an e-mail to offer to post the full res picture and got the thing returned "undeliverable". If you're going to come and spread your dysinformation and bash forum members, you really should have guts enough to take responsibility for your actions (no PS pun intended :o)

Pull the image into a photo editor, and zoom to 400%,
It's JPG artifacts (those 8x8 blocks of pixels, forced to
be a similar color).
