Thanks mac_paolo. This ghost... well you are right, the thing is that I have a kind of religion : do the photoshop to the point of what's on the slide. You are right on the fact that no ghost would make the picture more simple and "direct". But I find interesting the presence of this ghost, it's also shows the strength of the sun. In fact I'm in the middle of two religions : the one that put the impact and the reading of the picture in itself number 1 and the one who put in number 1 the subjects on the pictures. As we say in french : between the two, my heart swings... Sorry for the awful translation. I'm opened for a better one or maybe the english equivalent...
BTW, I always shoot the same picture with DSLR to double check the exposure with same parameters. The DSLR version has a white sun...
