I am a photographer, own my own place, 60 years of age. Around 2001, I hired a young man, fresh out of of high school to help with various duties at the studio. His interest was technology, but was equally interested in photography. As the digital revolution emerged and became such a big part of the industry, he embraced it. And he took over all tech related duties, fine with me, as was doing the photography, in 2011, he left quite suddenly to start his own business, and I found the amount of knowledge I'd learned was sorely lacking.
Now I'm still coping with the absence of my tech whiz kid. And still struggling with certain areas I counted on him for.
