I went outside at the edge of darkness, with an ND8 filter on the lens. I was set up for a 4 minute exposure to blur the clouds and the fog.
I interrupted this exposure after 9 seconds, because I realized I forgot to cover the eyepiece. In reviewing the images, I realized I should have tried a short exposure. I like the striking pattern in the clouds, centered over the isthmus of land.
To salvage this exposure, I had to brighten it by 5 stops in Lightroom (the maximum allowed), and then a bit more in Photoshop. The Pentax K-5 II holds up well, as usual.
