28 days
 

OK 28 days as seen from my attic window. Details available to the curious.

?? Moon or sun?

I don't know what that is but its cool as hell.

It's the sun. I will keep making these. If you look closely you can see individual traces of the sun's path. At certain times of the year the sun changes altitude more rapidly than other so there is a bigger space between the days. Also the number of overcast days creates different spacing between the paths.

Here is a detail, note the gaps as the sun passed behind clouds.

cool how did you do it ???? video or still ???

Awesome.

Blue solar filter? What's with the wide-angle distortion?

Bravo, fill us in on the equipment. :confused:

HAHAHAHAHA!
Are you all sitting down?
The "camera" is a one quart paint can (unused) with a .040" hole drilled in one side as a pinhole. The hole is a little too big, so the image is a bit blurrier than I'd like. I'd like to find a 1/64 bit or a pal with a laser cutter...

The image is formed on "printing out paper" which is a gelatin silver paper that was common in the early days of photography. It has an excess of silver chloride and so it "prints out" from exposure to strong UV sources rather than "developing out" like modern papers. Remember studio proofs that were orange and faded? Same stuff.

The image comes out orange and brown and reversed (negative). I scanned it into p'shop and reversed the values/colors. Hence, orange-->Blue.

It is extremely slow, when used to print from a negative, exposures can range from several minutes to hours in bright sun. In the pinhole camera a one month exposure for the landscape was barely adequate.

Each day records a different arc. I've got a dozen of these and I am thinking of setting them up all over town. I'll post the images next month. I'm going to check the almanac to see when we get the best separation between the days arcs.

Originally, I thought about doing a solstice to solstice or equinox to equinox image, but I realized things might get clotted.

The wide angle effect is from the curve of the paint can.

The view to the north, about 6 weeks

Awesome! Brilliant! Creative!

More!

Cool as HELL !!!!!
I rember a link some where about a guy that canabolized a scanner and made a camera , crude and slow , but it made some interesting images .

For some REALY small drill bits go to a welding supply store , ask for a tip drill set , a whole selection of small drill bits with a pin vice to hold them , not that expenceve ( -$20. i think ) .

I wounder what would happen if you made different colored celuloid filters , you could experament to see what works bets .

Really cool, foot! :thumbsup: I remember doing some experimenting with pinhole cameras way back in high school photography classes. Interesting and lots of fun!

I can't wait to see more of these.

Do you think they'll let you post from Guantanamo Bay? Be careful, we don't need an orange alert. :lol:

What's it, E.T.?

I've never seen that paint can before in my life. I don't know what you're talking about. :cool:



Billy,
It's the sun making its way across the sky, 28 times.
