Stefan Giftthaler's deliberately out of focus photo series entitled 'Color Mood' subtly exudes retro charm. The hazy overlay coupled with the brilliant combination of colors and shapes add a new dimension to color blocking. The styling enhances the overall concept perfectly.
He has used this 'hazy' technique in number of his shoots, which have a tendency of making you feel like you're in some kind of drug induced state - in the best possible way of course :).
If you can't tell already, I think his vision is genius!
