When I retired I bought a pocket camera to capture photos of our grandkids. But my unsteady hands (essential tremor) made the pictures blurry. A friend steered me to a DSLR and showed me how shutter speed could offset my shakes. Image stabilization lenses helped even more, hence "lensjack."
We live in an extraordinary time to be learning photography. Giants from Henri Cartier-Bresson to Arnold Newman and beyond have paved the way for contemporary pros who awaken our senses, stir our souls, and even alter the course of human events.
Just look at Nick Ut's "Napalm Girl" - http://ti.me/2pzsLHt - or Brent Stirton's "Gorilla In The Congo" - http://ti.me/2iJMl1g.
As a hobbyist shooting mostly on the fly, my aspirations are decidedly more modest. Photography's joy for me lies in documenting simple memories of people, places, and moments we've enjoyed, and sharing them here with family and friends.
