I have tried any number of places on the web (incl. the Adobe forums) to get an answer to this question and so far no luck. I'm using Lightroom 3 Beta. All previews are accurate EXCEPT the Develop Module preview. There is no true black. Shadows look flat and washed out in ALL FILES from all cameras. All other previews in other Modules are fine. also in Lightroom 2 the Develop preview is fine also...no shadow issues on preview. I'm on a carefully calibrated apple 30 inch display using Snow Leopard.
Anyone else have this issue with Beta 3?
Many thanks! Eleanor
