While going for a bike ride this morning, the open sign for a stained glass shop caught my eye. It has this panel of different colours on top of it, so I took a few pictures at different sides and angles to get the best background and pattern in the glass that I could. This was what resulted.
I took this with my 24-70mm lens, shooting at 1/500 and f2.8 with an ISO of 100. I wanted the background to be as blurry as possible, and the subject was all on a fat focal plane, so I could open up to 2.8 without fear.
