Volcano Steam Plume

Last year on a trip to Volcanoes National Park, HI - I was excited to see magma flowing into the sea. Unfortunately, the magma flow was blocked by a small hill dried lava, and closer access was not allowed. All you could really see during the day was a huge steam plume. However, as it got darker, the base of the plume lit up with some fairly surreal colors, and the long exposure required smeared out the steam plume nicely. I used 2 exposures - one for the sky, and one for the black lava foreground, which actually has a lot of detail in a larger print.
