Open the image that you want to convert in Photoshop. This one, from Finnish photographer Mikko Reinikainen, is striking as a color photo, but its vintage style makes it a good candidate for the black-and-white treatment. Go to Filter > Nik Software > Silver Efex Pro 2 to start working in the plug-in. As you adjust your image, Photoshop remains running in the background.
