Graynomad:
Thanks panzar, for the moment just a jpeg maybe 2000px on the long side will do. If possible square, shot from as far away as possible with a long lens, no pincushion/barrel distortion, even light, no hot spots etc.You can email me rob@robgray.com.
EDIT: Oh, and a plane background, doesn't matter what colour.
