Ah, Gillian, I rarely plan the effects... even less when I am roaming the streets. I was taking some pics to my son's girlfriend when she was trapped in the middle of the street and then, in this one, she just vanished ;)...
Here is one of a couple I took... with her on it ;)

sounds like a fun photography expedition @nolasco. 😊
That one's interesting too, with the one stationary car and the other moving.
It was, really, I'm still stuck with the photos edition... but I will get there! Thanks my dear Gillian!
