At today's example of the RAAF Museum's thrice-weekly 'Interactives' I grabbed a couple of shots of the Museum's Sopwith Pup replica, and noticed a phenomenon I'd not observed before.
It was a warmish 33 degrees C, with very light winds (7kmh, according to the local weather station), and I think as a result of these conditions, the Pup became distorted in some odd details: close observation of the wheels in all of these photos and the fuselage roundels in the images above and below show that they're no longer the circles they are in reality, but look 'retouched'.
Strange! (I should add, for those that care about such things, that all three images are full frame and unretouched except for resizing and the copyright note. The lens was at 500mm.)
Nevertheless, it was a good day to see such are a rare machine in action, and the audience clearly enjoyed it.
