Captured on my Nexus 6P which has an f/2 aperture. Used the lightroom camera app for raw dng. I focused on my car window with droplets from the recent rain. The tree was about 100 feet away and spidered in the bokeh. I didn't go overboard with color grading. The original image had some blue in the sky so I brought that out but two tone with a almost unseen magenta and green. I just wanted a cold and dramatic look.
