Didn't Renner die in 2020?

[Tin Can]

Well, I am sad he has passed, such a joyous soul as gleaned from his book

Rest in Peace, Eric Renner

Your book is inspirational!

I met Eric Renner in the 1990s, The Pinhole Journal he published for many years with his wife Nancy Spencer and the Pinhole book are pretty wonderful.

The book is very useful and shows image variations we never see on this forum

A pinhole is not a lens optically, physically, nor mathematically. A completely different beast that fools you to call it a lens.

OK a Pinhole 'acts' as lens, but is only an aperture

However, we now know light bends without a lens

It's a metaphor.

Doesn't a pinhole demonstrated the duality of light, i.e. that light acts as if it is both a particle and a wave. A lens bends light same as water or any other medium light can travel thru, at the interface. Or is that just diffraction at the pinhole itself helps cause an upside down image with no bending at all. As you can tell I may be a little confused. Been that way since high school when I asked the Physics teacher "What is Light?" and got no satisfactory answer. Then there is that famous 2-slit experiment and Mr Einstein.
