Or maybe it is because of the many more images I see regularly by my digital photography students or on contemplative photography forums that this has arisen. As a final exam exercise, I randomly selected images from my files and had my students rank, edit and make a slideshow of them. I included a wide variety of both "good" and "bad" images for them to consider. I found their selections to be quite enlightening. In some cases, students rejected what I considered my "best" and chose to rank highly images that I found pedantic, even boring. Taste truly is subjective, but perhaps there are some key factors to consider, particularly in a time period when we are overly exposed to digital photos.
This top image stopped me in my tracks after a compelling day of mahamudra meditation (a practice of looking at the mind and sense perceptions with inquisitiveness about the direct experience.) It is called "Emptiness/Luminosity", which are terms used to describe the fleeting yet vivid experience of the mind in the moment. This image is compelling to me because it relates directly to my state of mind and remains as a postcard of that experience. But does it translate to others? This is always the open question for the artist.
