Re: Noise!!
Do I spot -1ev exposure offset? If you had to lift the pictures in Lightroom as a result you might have enhanced the noise. The exif also shows sharpness and saturation as +2 which might not be a good start. Also does that camera do Shadow Adjustment, which also tempts noise..
None of this explains the difference between the two shots, unless the slower speed switches on frame subtract, and that cleaned things up somehow?
No. I'm talking out of my elbow here, I only use raw file mode. TBH I have no idea

Re: Noise!!
Dave
I don't want to hijack your thread, but having played with my recent 12-60mm acquisition at the weekend I was surprised by what I thought to be noise (or certainly what appears to be banding) in the shot below in the bottom left hand corner.
It is a RAW file straight out of the camera that has only been converted in LR2.7. I had been using LV the day before for some macro work but I don't recall using LV before I took this shot (with the intention to try and get a 'starburst' and lens flare by shooting at f11).
Whilst the histogram shows unsurprisingly that the image is blown in clouds and the sun, none of the image is clipped at the other end. I had forgot to reset the EV having shot elsewhere in the garden and is +0.3 (which won't help of course).
Any suggestions?
Thanks in advanceDavid

These days I am no longer afraid of the dark and I am happy to let small parts of an image go to true black
You could always use "select by colour range" to pick out the shadows and then give them a good noise reducing.. there isn't usually an awful lot of detail in the shadows

Re: Noise!!
I'm still curious why Dave's photos are so different, or did I miss something? I use live view a lot when shooting landscapes, wasn't even aware that it could heat up the sensor. I always have it flipped to the side though, but maybe that doesn't matter?-----------

I use live view a lot for my landscape work, only once have I had the sensor overheat, it shut the camera down. But that was on a very extended nighttime shoot.sigpicDave

Re: Noise!!
My CRT 23 inch Mitsubishi Diamondtron is pretty good and I keep it calibrated, but I can't see obvious problems with any of the images.
It looks like the second one of the adaptor photo's is angled and shows up the texture of the anodising, whereas the first isn't.
What monitors are you using, that show up problems in the images?
