I had lunch with photographer Trey Ratcliff today, who told me a neat trick. Tape your Apple iPhone or other smartphone into your shoebox eclipse viewer — so that the lens aligns with your pinhole. That lets you take pictures, reduce glare and you won’t go blind, either.
Caution: NEVER stare at the sun, even at the height of the eclipse when just a sliver of light is showing. Your retinas don’t have nerves — so it won’t hurt — but looking at the sun will in fact irreversibly damage your retina.
