It takes some time. And patience... As soon as I pick my camera from my own lap she says " NO ". I then rise it to my eye, and she insists: " Papa, he dit NO ! " (Dad, I said NO!).
First shot. Hit! But her fan is covering most of her face (except her spying eye).
A few minutes later, second try. She has just folded her fan. In my mind, I view myself being faster at raising my camera and focusing than her opening her fan and covering her face again.
Fast synchronized (trained) movement: Camera - Eye - Focus - Click.
Focus check (playback) on the viewfinder... She raised her other hand....!!! How could she be that fast!?!? And fully synced with the shutter!!!
After a while of playful wrestling...
...she relaxes. The game is over. The weather is too hot here in summer for any unnecessary movement...
