Lightroom Luminance Control

[j_mike_mc]

I am running LR3 and I have a question about the luminance control. It seems that it only previews when the photo is zoomed in. I can make changes when zoomed in - but when I zoom out the changes go away. Zoom back in and the changes are there. I don't remember it working this way before but I could be nuts. Anyone have any insight on this phenomenon.

Thanks _jmm

You're talking bout the luminance sliders under the HSL/Color/B&W section?
They work at any zoom level or at zero magnification. Perhaps the change is subtle enough that you only see it when zoomed in???
Is the image your working on a .jpg or a raw file?

It's part of how lightroom speeds up the way it works. One thing you can try is rendering 1:1 previews. It's located in the library panel, under Library - Previews - render 1:1 previews. then you can build them just for your current image, or for all images.

often, the downsampling needed to show the whole image can make the subtle effect invisible, especially depending on how the image is being rendered. The effect will be there - if you print it, or export to lightroom or save as tiff, it will apply what you've done. I think there's also a warning that you can't see the effects at less than 1:1 magnification
