Selfie of a Selfie

Study day today trying to learn more about darkroom stuff I'm integrating into my photography. As it seems G at Blipcentral is on the same old school track as I am currently ;-)

Also did some experiments with my remote controlled Sony QX30. 

This is one of them, a 'handsfree' selfie of a selfie and no... 

Nobody took this photo for me as I was all alone in the house, nor did I use a self timer.  

So how did I do it?
