10D long exposure noise like this---------->

we haven't seen the explanation for this yet. Is it just an anamoly. When does it occur. We don't know yet.

You can't just this based on two photos. Yes... two photos. Because photos 2 and 3 might as well be the same photo.

Hot pixels are a fact of life for digital cameras. Otherwise, the
photo does look very clean.

Hey, before any of you flame me, look at the pictures by Maurice
and tell me what you think?
I think they aren't so bad; a big step in the right direction from pretty much ANY digital camera on the market, except the D60, 1Ds, and specialized systems that are only good for astrophotog.

Look at the full-sized images. The first thing you see is that the image is covered with specs. It's to the point that they seriously detract from the image. I think we can all agree on that. They'll downsample away and make great web images, but the spots will definately show up on a print. But look around the rest of the image; there's no noise at all. Detail looks okay, but flat areas aren't any noisier than they would be at 1/1000th sec. So at least if you're able to get your exposure before the hot pixels show up, it should look great. In this four minute exposure, though, there are way too many specs to clone out by hand...

At 100%, my D60's images look a little better than this after a 20 minute exposure. The extreme right edge of the frame has that magenta cloud, so I'm forced to compose for an 8x10, but if I do that, I can get wonderful web-sized photos up to 45 minutes so far, and good prints up to five to ten minutes. I start noticing a few specs in my images around five minutes, the bar starts to show up at some point before ten minutes, and the specs get progressively ( but slowly ) worse from there. My prints show the specs, and I'd say there starts to be enough of them to be a distraction around ten or fifteen minutes.

This is my D60 at ISO 100 for 20 minutes, at f/5.6:



This is ISO 200 for 8 1/2 minutes, at f/4:



( Sorry -- there just wasn't any light to work with...! )

And, for reference, this is ISO 100 for 30 seconds, I think f/16:

 
What was he trying to get? The softest looking shots possible? That
fellow is a novice IMO.
Why do you think he posted thoses shots?

For us to see what the camera can do at different exposure values, just like many asked him to do.
 
Create an action with that command than you can run the action in batch mode using File-> Automate.

my D60 does better than this by far..........(and be sure to look
at the original sized)

Any DSLR beats unexposed film.
 
I have to confirm once again that I bought the camera in an ordinary shop as an usual production model with normal warranty, and at the normal (high in europe) price.

No preproduction or prototype.

All came in a box with alle the stuff (cables, charger, battery, etc).

Only manual and soft were missing (not yet ready for translation reasons) and are expected.

BTW, thanks to miro I tried the median filter at the recommended radius (which is the default setting) and all specs have disappeared.

The create a droplet from the action, so you can just drag the files to the droplet.

Well, thats not good news.

I'll admit for most people who dont shoot exposures at night, or long exposures through a telescope, it shouldn't matter too much.

But it seriously hampers the 10D in regards to astronomy. Wonderful things are being done with the D60 and the 1Ds. I hope there is a software update to fix it back to the way things were.

And for anyone who says they looked at the photos and dont see much wrong, whoa, what are you smoking?

There appear to be some issues about individual set-up of the monitor upon which they are viewed. The characteristics of the noise are consistent and not readily apparent at all settings dependent on the brightness levels chosen.

The first one looks way cleaner than the much shorter 30 second
exposures I got out of my D60. I found that anything more than 30
seconds with my D60 was basically worthless. The second and third
really look bad, but I don't ever expect to shoot exposures that
long.
I don't tihnk my D60 is all that worthless, unless there just isn't any light at all to work with:



Not a great picture, and unfortionately I think it was too dark to be able to create a great picture that night. But for the exposure, the original is pretty damn clean...
