I have been wanting to photograph these lights, which run along the edge of the ceiling of my sunroom and reflect magically in the various panes of glass. I just couldn’t come up with an interesting composition. One evening recently I was exploring the multiple exposure feature of my Nikon D850 camera body. This allows the photographer to make several exposures, which the camera then combines into a single image–and a raw file, at that. The D850 allows for three various ways of merging the images–average, add, or darken. Previous Nikon cameras only averaged the gain, or brightness, of each image. With the darken mode, the camera chooses the darkest parts from each frame; conversely, with the lighten mode, the camera chooses the brightest parts from each exposure. Here is the result of a composite of six exposures, using the lighten mode and aiming at the corner of the ceiling.
This experimentation led me to try multiple exposure of my front door in its winter dress. I tried two exposures, adjusting for the brightness of the light and wreath. I then wanted to frame the door with the sunroom lights and two additional exposures. The result was not pleasing, since I needed to do some perspective control on the doorway. So, this final image is actually a post-processing composite of four images: two of the door, controlled for perspective and blended for exposure, and two of the lights, one along the side and one at the top.
