I have been photographing for a few years now, mostly urban landscapes, among others - abandoned sites. I am not an artistic kind of guy, more of a perfectionist, so my photos are usually as realistic as possible, sometimes with a bit of glossiness on top to make them look what the majority would call "pretty".
Now, I want to develop myself in a more artistic way, perhaps, by using some post-processing filters, which would make my photos look rather moody than artificial. I am wondering how to capture the mood like in photographs by Colin Delfosse (from outoffocus.be: this & this)? I tried playing in Photoshop with different settings - saturation, contrast, photo filters, hue - but did not achieve the effect these photos have on me. Where would you start?
