Yes, it can be habit-forming! Once you start moving your camera during a slow-shutter exposure and see the emerging colors and shapes, you will want to do it again. And, again, … Of course, the colorful leaves on the trees and on the ground also attract the attention of the camera as it tries to draw random lines.
I still do not have full-fledged control of the process and rely on randomness and luck. Not that they are not helping, but I would like to gain a little more control over the process. What I notice is that bright colors on dark backgrounds with slight underexposure seem to produce more defined lines. At the same time, I am also trying to leave some hints of the objects when possible. Selecting patches of color with color and luminosity contrast still a productive start of the exposure.
In Lightroom, I enhance the contrast and boost the blacks. Because of the smearing of light over dark areas, they get a little weakened. Pulling the blacks down brings the image closer to the contrast range I photographed. Colors also wash out somewhat because of the movement and need some push on the HSL or other color adjustments. In post-processing, I aim to produce a color, line, and possibly some shape coherence.
Here are the results from the last couple of outings. Refraining from posting about 40-50 photographs I initially selected, I present only sixteen in this collection.
