In terms of composition:
i) Elements of the composition of the claimant's work which have not been taken are the prominent arches of the bridge and the river, the steps in the foreground and the prominent lamppost. The angle to the vertical is somewhat different since the road can be seen with the bus sitting on it in the defendants' image whereas from the angle of the claimant's picture a balustrade obscures the road. The angle presented by the facade of the Houses of Parliament is different: in the defendants' image the perspective of the facade falls away more sharply whereas in the claimant's image there is much less perspective. The bus is on the central right side of the image, touching Big Ben, it is not left of centre as in the claimant's picture. The defendants' bus is bigger and presents a slightly different angle to the viewer. There are no people in front of the defendants' bus.
ii) Although the images undoubtedly differ in their composition, elements of the overall composition of the claimant's image have been reproduced. The bus is a Routemaster, driving from right to left with Big Ben on the right of the bus. The riverside facade of the Houses of Parliament is part of the image. The bus is on Westminster Bridge (albeit in a different place) in both images. This is obvious in the claimant's image and can be seen from the presence of the balustrade on the left in the defendants' image. There are some people visible but they are small (and in different places). There is no other obvious traffic. The edge of Portcullis house is visible on the right. Running from top to bottom, there is a substantial amount of sky in the picture (albeit more in the claimant's) and the top of the bus is roughly the same height as the facade of the Houses of Parliament.
In terms of visual contrast features:
i) The element of bright red bus against a black and white background has been reproduced.
ii) The element of the blank white sky, which creates a strong sky line, has been reproduced. A small point arose that the image produced by Sphere actually has no sky at all, so that it takes on the background of the box it is placed on. Nothing turns on that since in use it is placed on a white (or very pale grey) tin.
