If you look closely, you can see Steve Davidson's face. He's been found! :-)

I would say that is a highly speculative theory, to be kind.

Take that to the DPC conspiracy thread :-D

Looks more like cheesecake to me ... or maybe quiche : )

Wasn't that photo submitted to the "Image without Subject", but DQ'ed because it wasn't shot during the challenge period? :-)

I couldn't resist...so I did a bit of PSing to see what happened.

The first has had levels, curves, selective color, a bit of cloning out spots and scratches, NoisewarePro. The others are quick and dirty Artistic effects at default settings...DryBrush, Fresco, and Watercolor respectively.

Increase the contrast and you can make out the building's lines.

When I was surfing the net today, suddenly I went to a web site through google where I saw world’s first photograph by Joseph Nicephore Niepce. So I thought why not share it with you, my great photographic friends.
Link follows:

//www.hrc.utexas.edu/exhibitions/permanent/wfp/


FYI, there is a reproduction (an image created using the same process from the same location on similar materials) in the Museum of photography in Bradford, UK.

From the link:

"The approximately eight-hour long exposure required to make the heliograph was projected on a polished pewter plate coated with bitumen of Judea (an asphalt compound). The plate was then washed in a mixture of oil of lavender and turpentine, which dissolved away the areas that were not hardened by the exposure. The result was a direct positive image, where the residual bitumen represented the highlights and the visible portions of the pewter plate represented the shadows."

The guy clearly needed a faster lens.

I'm still waiting on someone to try it with banks of CMOS or CCD snesors. I challenge someone here to turn a van into a really large digital camera. :-)


It's been done for pinhole photography - but the images are several feet wide, so would require a huge digi-sensor!

Like the FBI really needs your help thinking up new ways to spy on us ... thanks : )

Ok, now let's start guessing at the focal ratio...

Based on the pictures I've seen of the project - let's say the focal length is 50 feet and the aperture is 1/2 inch (gumball sized opening) - in other words, f/1200 perhaps. (I'm only guessing on the room dimensions, and presuming the "lens" opening is about 1/2 inch.) Or, f/2400 if the focal length is 100' with the same lens opening.
Kind of interesting.

I drove the base at lunch today - couldn't find the facility yet - it's a maze of old, overgrown roads on 300+ acres. No signs, at least not that I could spot today. I'll explore some more in a day or so and report back. No one to ask where building 115 is! (Let alone ask where the "camera obscura" is... "the wha....?" they'd probably say.)

Stay tuned - more info when I find the building and someone to talk to. I'd like to know more about the dimensions of the "camera". What I know so far is that the image will be about 111 feet by about 31 feet, and the "lens" opening is gumball sized. We're still missing some variables here!

Did find this:

Diagram Link

Based on that diagram, the focal length is 56 feet, aperture is 3/4 inch, so f/896 is our ratio! Wow, now THAT'S SHARP!

It's amazing that someone so young could have a profound impact on society even to this day. Perhaps it is his youth and the ignorance of the 'rules' that kept him from saying 'It can't be done!'
So basically screw the rules, lets have some fun!

Maybe we should make that a challenge. :-)

The camera obscura was around much earlier

LOL I'm too slow :P

Maybe that was the first with a silver-salts emulsion ... Niepce's process used completely different chemicals ... but it is the earliest image permanently recorded by means of light's action on an emulsion.

Not that is couldn't have been invented by the Romans.
