at 800, it's really that bad ah? ha. i think you got high high taste.
on second look it looks like the images have been compressed too much to really tell
look at the compression artefacts in the sky even for iso 100
might have mistaken those for noise

Here is the final set of ISO comparison pictures from today's night shot as the Esplanade. No external noise reduction software was used on the images. Rest of the images can be found here

Canon 24-70mm f/2.8L, ISO 50, aperture of f/9
Take a closer look at the bottom right corner, you can see the "wave" being freeze and not smoothed out as in long exposure shot. It could be data corruption too???

I guess we need to turn down the brightness of our monitors. :bsmilie:
but I think you are right, hence I requested 100% crop of that building to see the shadow details. As for the sky, I don't think it is the cause of compression artifact.

Read again...... he said he could have used f/2.8 since its so clean at high ISOs.
Sir, your English more pro :bsmilie:

If you misread the thread, just say so.

Looking at the 100% size from the flickr site, it's still hard to really see what it is from the long exposure. Could be the reflection of some light from the oposite building. But since the other pictures does not have such problem, it could be from the way it was processed.
I have checked the exif and found that Adobe Photoshop CS3 Macintosh on it. That means it has been processed before by photoshop. The PictureFreak may have shoot it in raw and processed it in photoshop to produce the Jpeg image and in the process, there are some corrupted data in it.
Hi jopel,
100% size is available at his flickr site.

Click on each image to see the preview size and at the top of the image you will see All sizes link with the magnifying glass. click on it and select the maximum size.
Sorry to wake you up from your dreams. But the 5D2 noise at ISO 100 (even worse at ISO 50) is worse than 40D at the same ISO. No kidding. The 5D2 is designed for high ISO, and that's where it really shines. I am not advocating shooting high ISO for landscapes, just to point out a common fallacy.
Anyway, here is a 1 min exposure, ISO 800 landscape shot using the moon as the only light source, taken with the 450D. The stars in the night skies seem almost like white speckled noise against the blue backdrop. But they are really stars. :bsmilie:

Really? Where can I read more about this? Thanks!
Thanks.
Just viewed the iso 800, I have to say that either my monitor is too bright. Cos when I turn the brightness down almost all the way I really can't detect any noise.
I need to calibrate my monitor.

Hmm.. in my eyes, those speckles are 'hot pixels' instead. Why ? Logically, if they can be see in the sky that way, you will also seem the reflection of some of them on the lake surface. But I see none. :dunno:
And you have to be kidding me that at ISO 800 for 1 minute you do not get noise? 30s exposure at ISO 800 produces tons of noise for the 40D as far as I've seen and experienced. Even the technicians at CPS admit that.
