Ah, finally!

I cannot say that I'm constantly on the outlook for abstract images, but this afternoon something caught my eye at the wall in our staircase: The sun was shining through a window above and painted some light on the wall. A simple tryptich with just a faint hint of spectral colors. Got my cam, framed the shot and went back to the computer immediately as it was clear that without some amount of post-processing there would be no relevant image.
Boy was I right after some tweaking!
See for yourself what turned up in Lightroom after some judicious adjustments:



Hope you like it!
