What makes a random passer-by worth photographing? Perhaps, just perhaps, the key is not in the subject but in the way one approaches the subject: distance, composition, movement. I guess I have developed a bit of a signature look, in this regard. Color, too, why not. (Yes, color again... a 2018 new direction.)
I'm not sure this is the path I want to keep following going forward, but when you hit an inspirational 'blank', as I have hit in the past couple of months, the best cure is to 'just do it', and if 'doing it' means going back to familiar habits that you thought you had overcome, so be it... Of course, nothing very familiar in shooting color, for me; so that's at least part of the creativity kickstart I was trying to initiate with these outings.
