Hard to think of Vivian shooting with a Hassy.....
"Kuh-Lunk!"
I've done what I'll call "surreptitious photography" and the only reasonable contenders have been my Rollei and my digital, the latter with a flip up back viewer and no audio effects on the shutter. IMNSHO. The digital has been great, too, for just having it slung on my side walking past people on the beach. Lots of misaimed pics, but the "film" is free, s it's just another reasonable MO.
Anything eye level just announces to the world "I'm looking at you."
So, how about that Vivan Maeir? Enough camera stuff.
I think there are several things that make this story so powerful. First, of course, the GREAT photographs. Then we pile on these facts: She never displayed them, sought an audience for them, tried to make money from them. That they were almost lost to the world, forever. That she apparently never printed them. That someone who knew nothing about her or photography tripped over the cache, understood what he had, and had the cash (catchy play on words here, eh?) to buy not just the first tub, but ones that others bought.
The old phrase "You can't make this stuff up," sure applies here.
