Thanks for answering. Hugo

Answer 1

Go to the library module, grid view. Highlight all your images and create a new collection. One of the options when you create the new collection is to make new virtual copies. The collection will consist of virtual copies of all your original files. Then, just work with the collection and create your black-and-white images. The virtual copies can be exported just like the regular images. So you can export color and black-and-white versions.
