Emergency eyeglasses

A good idea for emergency eyeglasses made from cardboard. In photographic terms this works by basically decreasing the aperture of your eyeballs. That has the effect of increasing the depth-of-field, which helps to compensate for your eyes’ faulty focusing hardware. Pinhole cameras, which have huge DOF and no focusing capability at all, use this same principle.

Inuit-like slitted visors used to protect against snow blindness are sort of similar. They reduce the amount of light coming in to prevent snowblindness. A variation on that design was also used by the military to protect against bright flashes from bomb tests. (And by the Mole Man, of course.) I suspect they’d work great as emergency sunglasses too. But if you’re trying for emergency vision correction, I think this pinhole method will work better than a slit.

I haven’t had time to blog on the developing doctored and staged photo scandal at Reuters. The blogosphere has done a fantastic job of exposing this, but, as Anne Althouse asks, how many
other faked and dishonestly presented photos are out there? If
photojournalists have any respect for their profession at all then they
need to do something, right now. I suggest they begin with the measures outlined in this post at A Jacksonian:
Note to the MSM, RE: Images, still and motion, veracity of same.

I agree completely with with that post. In fact, I suggested a similar solution during the last wave of photo fakery. Unfortunately, for now the media outlets and wire services seem to be trying very hard to look the other way. Their stringers send in those juicy action-packed photos. Why spoil a good thing by asking too many questions about how they got them or if they’re real? I can’t trust them anymore.

If you don’t know what I’m talking about, begin here. Michelle Malkin has a great retrospective roundup of this whole sordid business, with lots of links to other bloggers covering the story. And Ed Driscoll looks at the big picture (no pun intended).
