Photo for today --"Beacons" an infra-red study

Not all cameras can shoot IR satisfactorilly. My Nikon 5700 doesn't supress the IR as much as my Panasonic FZ50 so with a proper IR filter, not just a deep red filter, Wratten 87 equivalent, I get the IR result without any redness. Exposures tend to be long such as one second at f/4 with 100 ISO so movement is blurred but the results are satisfying with some subjects.
