I have been working a lot on portraiture, looking for something different. Both the subject and technique provided what I have been looking for.
At first I did them neon like, i.e. lines in color on black. Later I decided to do the actual color image because it makes a stronger image and gives plenty of possibilities to make variations.
In general one can say that selfies are a form of narcissism. Without going further into that notion one aspect is that the technique of the smartphone has had an explosive effect on making them. Therefore, the term zeitgeist is applicable. For me it is, after numerous trails, the ideal subject of portraiture.
