no problem - comments are good!! They help us spot things we may miss when we stare at our screens for too long!!
The reason the tiled floor is blurry up close is because I am consciously using depth-of-field to focus on the centre of the image - so that was actually set to blur out the far distance and immediate proximaty - like a subtle frame. I was trying to give the image some individuality from a standard rendering.
Similiarly this is why I swtitched to a 28mm camera to 'stretch' it out and make it abit more interesting and dynamic. I found the 35mm default camera a little boring in my previous renders - it looked like a still life or an architectual rendering :S
Like the film noir technique of stretching the perspective to create a feeling of uncomfortable reality. I want create something more artistic than photographic.
I will definitely dirty up the tiles when I get chance to match the dirty wood on the walls tho! They are far too shiny and clean
