the pictures are quite stunning, purple lightning? wonder how it changes colour? Different magnectic charge ?
Tell your friend that he did a great job taking these. I really love how they turned out. As far as the color, it happens everytime I take photos of lightening. I think it has something to do with the type of visible light that our eyes can see (including the lens of a camera). When you see other cool colors in photos of lightening, most professionals will use different color filters durning an exposure. I've seen others that the photographer just used photoshop to add the colors.
