I have been a distant observer of the installation of Matthew Harding's latest work Fruition, a wonderful piece in Royal Park. A few nights ago I had the chance to witness the lighting tests to see how best to display the work at night. A low powered sodium globe seems to be the choice of the selection team, to articulate the 'seed pods' in a camouflaging glow to match the street lighting. They have such a tremendous presence when you are near them, I encourage everyone to visit them, and then again in a few months when the lighting is installed
Here is an image under a higher powered metal halide. There is some awesome contrast going on there.
