Most of the time I do not bring a tripod with me when I travel with minimal gear. And that was the case on this trip to Paris a few years ago. For this long exposure shot of Musee du Louvre, I carefully sat the camera down on the edge of the reflection pool in front of the museum; and then composed the frame with the limited degrees of freedom. After some cropping and noise reduction during post-processing, I found the final image to be quite acceptable.
