Waiting Room is a preset that you can use in Silver Efex that gives the photo an expressive look, I think it is particularly suitable for portrait and street photography. I made the preset for use with people in waiting situations and portraits, but of course it can also be used for other purposes, you can try that yourself (I haven't done that yet). When using this preset I bring a lot of accents by playing with light and dark and with structure. More structure gives more accent. You can download the preset below. Install it in Silver Efex. At the bottom of this article is a link to a brief instruction how to install presets.
