On the pictures with a huge noise corrections (night sky), the display is:
- correct in the library & dev-module for 1:1 or other crop
- but not corrected when I display in dev module (Fit size)

Otherwise everything works fine:
- when I swith to & Go between Lib & Dev the noise appears/disapears
- when I crop/uncrop in dev, the noise appears/disapears
- when I print everythink is fine

This is not critical (as the data are correct), but it is not confortable to have a bad display.

I'm using LR 3.5 on Windows7 32.
My picture are pretty large (19MP leica or 50MP Hassy)

Benoit, this in a design issue, not a bug. There's quite a long thread around here somewhere about it, but here's a copy of a recent post from one of the mods/gurus at lightroomforums.net:

This is by design and is to be expected. Adobe installed an adaptive algorithm in the Develop module which determines whether to display NR in the 'less than 1:1' view modes. This algorithm is based on specific camera models and ISOs and operates independently more as less as judged necessary by the engineers. The intent is to avoid the performance hit of calculating and rendering NR in non-zoomed views. As you can imagine, the feature is not popular with all users, and there have been numerous suggestions to make it configurable, i.e. turn it on and off. To avoid it entirely, you have to work in a view 1:1 or closer. You can also switch to Library Loupe view, zoom into 1:1 and then back out.

Thanks Jim,
As a very old programmer (first computer hit at the college in 1970) and a yet older photographer (first Rolleilflex in 1966), I understand that this type of choices are not easy to make. If I had to vote I'd like to have this feature configurable. With the performance of the new computer it's probably acceptable.

Yesterday I had to develop a serial of firework's picture and I had to switch continuously between the lib & dev module. To select the views on a signifiant base. With my camera (Hassy50MP & Leica M9) the 1:1 is to small to do other thinks than details treatement.

By the way, I'd like a better integration between Dev & Library. But that's another story.
