Why is this image so expensive, because right after I took it, disaster struck.  I found this great scene and I was working it for all it was worth.  I had that great swirl in the water and some fantastic fall color in the background.  I decided that the image could be even better if I used a polarizer to remove some glare from the leaves and water.  Photographically this was a great decision but it caused me to fight with the filter holder which caused me to unlatch the tripod head.  Then I got my shot, but I forgot about the tripod head and when a picked up my tripod a heard a big splash.  My Canon 5D M IV and my Canon 17-40 mm lens were completely submerged.  I was able to retrieve them and I tried to dry it out and I sent it to Canon and they were both a complete loss.  Luckily the memory cards survived and I was able to get the images and my insurance should pay for most of the loss and as it turns out this image won second place in my camera club, so I guess it was all worth it in the end.
