"BuildingComposites – Blending multiple exposures, swapping out boring skies, or combining multiple elements using Perfect Layers are just a few examples of what you can do using Perfect Photo Suite 8.5."
"Tip: Select each photo in Lightroom and go to File > Plug-in Extras > Open as Layers in Perfect Layers 8. This will create a stack of the photos (layered file) allowing you to begin building your composite. Also, ‘Opening As Layers in Perfect Layers 8′ allows you to easily switch to other modules in the Suite for further editing and styling. Don’t be afraid to experiment with the blend modes found in the Layers Panel either."
