28 days - Page 5

I mailed mine off this morning. I'm looking forward to seeing the results. I was curious about one thing. I placed it outdoors tilted upwards. While I doubt any significant rain got into it, what would happen if a thin film of water temporarily covered the hole? Would it act like a lens? Would it invert the image, like the lens in a human eye?

OMG,
so many q's so little time. Here is richlevy's photo. mad props for calculating the angle of the dangle... it's always inverted, unless you have a prism. more later.
Bruce: nothing is foolproof to the sufficiently talented fool!

Promenea, another time I'd love to make the personal acceptance, but I'm not sure what is happening next.

BigV, and everyone else who wants a camera, there is going to be a slight delay while I get other ducks in a row, so to speak.

in the meantime:

Thanks. I got creative with a cardboard box, some duct tape, and a compass. What surprised me was the blurriness. I thought that the problem was that people were shooting though windows so I placed mine outdoors. I guess it is possible that there was minor shifting due to wind.

It's still a neat effect. Thanks for letting me in on the project.

footfootfoot · 04-04-2005, 07:36 PM

Yeah,
the blurriness is due more to the pinhole being too big. there is an optimal diameter, the formula is somewhere, but I didn't have a drill bit small enough for the focal length.

I'm hoping to see some free time in a few weeks and I will bore everyone with minutiae then. Until then, I expect you all to remain fascinated.

1/25 the square root of the distance between the pinhole aperture and the film plane (focal length)

another:
Pinhole diameter = 0.0073 * SQR(focal length)
where Diameter and focal length are in inches and SQR stands for square root.

* For metric system the formula becomes:

Pinhole diameter = 0.03679 * SQR(focal length)
where pinhole Diameter and focal length are in millimeters

* f/stop = focal length / pinhole diameter

foot3 - i believe that you have posted 100% accurate info so this is not a dig at you...

i had an amusing thought when i read your post. the cellar is the only place in the world that you can't just BS your way through info like that to impress people. some cellarite will invariably take your "facts" and test them and report back to the cellar if you were off by even .00000000000001. i love this place.

xoxoxoBruce · 04-04-2005, 10:11 PM

I have some pretty small drills when you figure out what you need.

footfootfoot · 04-07-2005, 06:05 PM

Here is Promenea's entry.

A quick aside; where I've been.

I spent the last few weeks in the darkroom printing a huge job of about 55 custom archival prints. tedious. When they were all done and only needed one last step, toning, some complex technical i won't go into it here thing happened and every last fucking print was ruined. shit piss fuck.

See you all in a month.

404Error · 04-07-2005, 08:17 PM

I think that's the best one yet. Lots of well defined trails, looks like a wide angle shot.

Sorry to hear about your darkroom troubles, foot.

I think somebody is gonna get blamed 'cause that statement sounds like, "technically it's not my fault".

Promenea · 04-11-2005, 08:54 AM

Oooohhhhh cool!! Damn that I had to move when I did. The first 3 trails were consequetive Sundays and the rest of the 28 were daily.

I'm thinking that every 3 days would make a really neat shot. When you are ready to send out more footfoot, let me know. I have a new location to shoot from.

Will I be able to get a higher resolution jpg for printing?

footfootfoot · 04-24-2005, 10:10 PM

Hey folks,
I am still sorting things out in the darkroom, today was somewhat successful. I'm still getting everything "dialed–in" as they say.

Even though I've been doing this sort of thing since 1972, this is an entirely new set up and I seem to have unpacked some gremlins along with the rest of the gear.

Anyway, I have all your originals stored safely for the time being. Some of you want high res. files emailed. That is not really a problem, but I have dial up (56k) so before I say "ya sure ya betcha" tell me how high is high? I can also toodle on down the block and scan these at my friend's place who has broad band. Let me know what kind of file, jpeg, tiff what ever.

If you want to have the original back I can tone and fix it for you. The process will wipe out any faint detail, but will give better separation in the sun trails. The image will also be a negative and reversed.

It will probably be the end of may before I can get to this.

Finally, we are still waiting to see the results from Jinx and LJ. I have a sinking feeling that there are a bunch of geraniums planted in the cans.

richlevy · 05-15-2005, 08:01 AM

I submitted my pinhole photo to Megapixel World, a BBS devoted to photography. Thanks foot!

xoxoxoBruce · 05-15-2005, 09:31 PM

That's a nice site Rich, I found this panorama there. Claims it was done with a 35mm reflex.
