I posted this image to a site a friend directed me to where photographers submit images for artists to use.
I got one comment asking if the image had been processed or was "natural" I told the poster that all my images are processed, a necessity for digital photography. I told her this was enhanced and I used artistic license to depict the aurora as it should be, not actually was, so no it was not natural. And in fact it was changed to make it more exaggerated as a study for someone to paint the aurora. Her response, which I am paraphrasing, was that it was unfortunate I did not supply what the northern lights are actually like. A valid point, but however I was a little surprised to have it from a painter.
I have now officially moved into unnatural processing. There may be no way back.
