photography's longest long-exposure ever taken

Cool.

I'm gonna go for 7 months and steal his thunder.

6 months and a day should do.

Don't forget to leave the "reduce long-exposure noise" turned on

pretty cool, My sister did one for her photo class in high school for 4 months in our backyard. It came out pretty interesting because some of the stuff was moved and you got to see it shift and star trails were cool also.

...B&W Makes a 20 stop astro-photographic filter...

They did, but it's no longer available. Their current darkest is 10 stops.

man, 30 stops haha thats pretty crazy, but do-able! don't take my word though I don't want to be liable for any fried sensors/processors

Wow, old post but I did this same experiment but my exposure was only 25 days long. It doesn't look as great as that first photo, but hey, for a first try I think it looks pretty cool:

I might have to try this. Looks like an interesting project.

@luckless It's actually a great project, and no developing chemicals are needed. Just a canister, foil, needle and some photo paper!

I just moved so I'm planning to set some new ones up!

Not for people who chimp their way to proper exposures.

wait, no developing chemicals? What kind of paper is used, and how do you stop it from being photo reactive? If there are no potentially hazardous chemicals to play with, then I don't know if I'm all that interested in it anymore...

Meh. Looks a little grainy.

Haha no it doesn't require chemicals. I'm not sure why but I guess after a certain time and amount of exposure, the paper doesn't need to be developed. I used Ultrafine VC Elite Black and White Photo Paper.

@iowajim It's a DIY pinhole camera, it's inevitable haha

I think another one was even longer for over 34-months period, also bit more fun:

unencumbered by the thought process- Would it be possible to just make a pinhole in a body cap?

I was told long ago about a japanese movie maker that needed images of familiar places with no people present or traffic, so the images were collected by using pinhole cameras. Longer exposures (smaller holes) for busier places, shorter exposures where there wasn't that much going on or the traffic wasn't as consistant so it didn't leave ghost trails on the image like a thousand cars passing in the exact same lane. I have played with pinholes alot but the results are generally only interesting in a technical way and usually flared or made useless by a slight movement of the camera during exposure,
it is harder than it sounds by a long shot.

that said, now I wonder about drilling a pinhole in a body cap. Does anyone have a reason that it wouldn't work?
