Depending on what genre you shoot in, you can often come home with literally thousands of images from a shoot, and culling them can be a tremendously tedious and annoying process. While you can cull in Lightroom, it is not always the fastest, particularly when it comes to rendering previews. Photo Mechanic is built with one purpose: to make culling large image sets and adding necessary info as efficient as possible. This excellent video tutorial will show you everything you need to get the most out of it.
