By diashow, I'm assuming you mean slideshow? It would be helpful if you posted some images showing the difference you're seeing.
This does not happen for me, if anything it's the opposite at times when LR needs to render the image. Does this happen to all of your images? How about if you go back to the same image again in Develop? What are your settings for rendering previews?
thanks for answering.
now this is amazing.as iīd read your answer iīd gone back into LR to look at this thing with the different colourrendering, and itīs gone!!!
then i checked what i changed since i posted and the thing is I reprofiled my monitor.
before it was profiled with spyder 2 using the software that came with it, then I gave the spyder 2 back and got the spyder 3 and then I profiled with that and a few days ago I got the color eyes display pro demo and used that and now the problems gone !!!(but we were talking ībout lips turning pink in portraits and not just slight different rendering).
so evidently this is the combination thats rendering the different profiles in the way they are intended to look.
As iīve read that lightroom uses the adobe RGB profile for the previews in the library mode, maybe itīs the same for the slideshow?
and considering all of this, itīs probably no use posting these since everybody will see them rendered differently...
so anyway the other problem is strange also.
when open a NEF in develop, thereīs this going from very sharp to softer (as iīve thought about this, itīs probably something to do with the compression of the preview ), but funny enough, when viewing the same file processed and sharpened in PS and saved as TIF, and opening that from library into develop, the thing doesnīt happen!!!
so thereīs still things out there in the digital universe that keep on amazing and annoying us.
cheers to all of you
