Thanks for the comments guys and gals.

Frances: If I do use the logo for my Desktop, then it is going to be in the centre of my screen and I am not going to have anything else near or around the logo. So, whilst your observation is good, I'm probably not going to go down that road. If however, I decide to make a scene, then what you say is correct. Input appreciated

beret: I've been trying to concentrate on the Apple itself and would have to say that I've not paid too much attention to the background and the direction of the light etc... But, of course, to keep you happy, that's the next thing I will look at! Input appreciated.
