How's this for long exposure?!!!

What is the longest exposure you've ever done? I am sure you can't beat this guy..

I don't think I've ever done more than 30 min.

Wow. you need some slow film and a tiny hole. Perhaps add a neutral density filter for good measure. Cool results though.

The funny thing is, he says he could do the exposures almost indefinitely...I agree it must be a very small hole and a very, very slow film.
I wonder if it is possible to do the same thing with digital???

The sensor will fry .

On the other hand, I can understand the use of pinholes and slow film, but how did he use to keep his camera steady for so long? Movement of the earth relative to the structures he was photographing itself won't give you a steady picture. Is there some technique?

Is there some technique...Yes..."Time"...

You gotta remember these are exposures measured in months and years...
You could remove an item for a day and then return it in the exact same spot and it would make very little difference...

Imagine, after 3 years, taking the film to lab and lab messing it up...

My longest was about five years. Yep, about the finest picture of a box top in a closet you could ever hope to see. :-)

Interesting as heck!

However, there has been a longer exposure. So long that the sun passing across the sky was reversed. Surf out pinhole resource. I'm not sure the photo is online. It might be necessary to actually pay for the image.

Masterpieces. He has done his math.
