Tech Details:
This image was processed using HDR software with only a single image. As a result the image is not strictly HDR but is, instead, tone-mapped.
Taken using a hand-held Nikon D7100 fitted with a Nikkor 12-24mm lense set to 19mm, ISO1250 Program mode, f/4.0, 1/30 sec, EV-0.67 exposure bias. HDR processing was done with free Open Source Luminance/Qtpfsgui using the Fattal tone-mapping operator to emphasize colour rather than texture. PP in free Open Source GIMP: adjust tone curve into a classic ‘S’ curve to get a more natural looking tonal range distribution, adjust perspective to remove keystoning, crop to a square format to cut off anything beyond the window frame, adjust contrast slightly, adjust colour balance to reduce green cast in a very mixed lighting environment, sharpen, add fine black and white frame, add bar and text on left, scale to 1800 wide for posting.
