Monochromatic, architectural digital photographs will appeal to the perfectionist in all of us

If, like me, you have this thing with straight lines then you'll love Nick Frank's work. This series entitled Mono Madness III celebrates all of the small details in beautiful architecture, boasting clean lines, repeat patterns and shadow play. The Munich-based photographer tends to alternate between bold, vibrant colour and striking black and white in his work, but it always retains its theme.

From criss-crossed roofing to swirling twists of metal, the results of this particular set are simply stunning. To see more from Frank, visit his portfolio on Behance.
