Lightroom has some useful tools for organizing and working with large collections of photos, and one particularly useful option is virtual copies. If you have not used them before or you want to get more out of them, check out this fantastic video tutorial that will show you everything you need to know to use virtual copies.
Coming to you from Anthony Morganti, this awesome video tutorial will show you the ins and outs of working with virtual copies in Lightroom. Virtual copies are exactly what they sound like: they are copies of your images that do not actually create multiple versions of the same file. In other words, they are simply multiple edits of the same image represented as distinct photos in the Lightroom roll. This allows you to, for example, create a color edit of a photo and a separate black and white edit should you wish to have prints of both. Or, if you are unsure of how you want to edit a shot, you can create multiple versions and select later. The beauty of the virtual copies is that they create very little additional overhead beyond the initial file. Check out the video above for the full rundown from Morganti.
