Portrait manipulations

I took this portrait on Saturday and I gave the CDRom back on Monday along with 52 prints. This was one of my favourites. I like it because of their expressions but also because of the digital manipulations. I extended my black background (£4.50 from the market) to make it look like it was a huge background in a huge room. It wasn't. I also like the high contrast monochrome version on the right. take a close look and you will see that there is a 'barn door' effect. The bottom of the photo is a little darker. Again this was all done by manipulation. Why bother buying specific lighting effects when a click of a button will do it?

Happy snapping
