Clearly I'm not charging enough for my photos.
I figured this out after I saw a story about a photograph of the Rhine river by Andreas Gursky that sold for $4.3 MILLION DOLLARS! The most expensive photograph ever sold at an auction.
I've uploaded the photo for your viewing pleasure… or perhaps, as in my case, your viewing annoyance. Now, I'm not saying it's a bad photo, art being subjective, but I'm going to go out on a limb here and say that seven figures for one print is a tad excessive.
