Sun's path June to December (Photo)
- nfnaaron 17y agoI was just explaining to my kid how you can tell your latitude from the sun's angle at noon, if you know the day. This picture solidified that idea.
- samratjp 17y agoSuch an elegant solution in the day of the never decreasing memory card sizes and megapixels.
- mortenjorck 17y agoYes. I can easily imagine a maximalist-geek solution involving a weatherproofed enclosure, a webcam, a solar array, a wi-fi antenna, and a server script with ImageMagick that exposure-compensates and additively composites each new image for 10 months.

- samratjp 17y agoThat would be funny. Maybe it'd be The Departed: Gosling Edition
- po 17y agoWait a minute... how do you scan an undeveloped piece of photographic paper? If you read the instructions it says to put the paper on a scanner in a dark room and just scan away. Doesn't the scanner immediately blow out the image? http://www.pinholephotography.org/Solargraph%20instructions.htm http://www.pinholephotography.org/Solargraph%20instructions....
- voidpointer 17y agoI was just wondering about the same thing. It's the super-long (over) exposure. See http://www.solargraphy.com/index.php?option=com_content&task=view&id=13&Itemid=14 http://www.solargraphy.com/index.php?option=com_content&...
- po 17y agoI don't know... this explanation just opens up a whole new set of questions for me. "Although there is a piece of black and white photosensitive paper inside the pinhole camera the result will be in colour." Huh? I think I'm doomed to spend the rest of the evening on wikipedia reading about photo paper chemistry.
- voidpointer 17y agoI'm surprised that he is able to scan the latent image from the exposed photographic paper without developing it. Especially since the scanner will further expose the paper so it would be useless afterwards... Maybe this is just working because the paper gets way overexposed and that will make the latent image actually show without development. Does anybody know what's going on there?
- voidpointer 17y agoOk, to answer my own question... It is the long exposure time. See http://www.solargraphy.com/index.php?option=com_content&task=view&id=13&Itemid=14 http://www.solargraphy.com/index.php?option=com_content&...
- po 17y agoWow, Google has a lot of good examples: http://www.google.com/images?&q=Solargraph http://www.google.com/images?&q=Solargraph

- thmz 17y agoThis appeared on Makezine last month. And it got me thinking: what would be the best way to do this with a webcam? pixel = (added pixel value of all frames) / total frames?
- kenj0418 17y agoWas I the only one expecting the picture to involve Larry Ellison and a wood-chipper?
