While up at @lawrenceuni.bsky.social Bjorklunden campus, I put a @solarcan.bsky.social Puck on a spinner for a day (facing upward), and was very pleased with the results. #pinhole

A few #Solarcan harvests from (or near) the #wintersolstice 1. 2nd Floor classroom at Appleton East, looking south. Late Aug - Dec 19. 2. SE, installed Sept 29 and removed Dec 18. This was the best exposure, showing leaves on the tree for a little while 3. South, Oct 19 - Dec 21
Times New Roman is a slightly more narrow font (that’s an economy thing - less printing is more money for a paper) than Calibri, so the State dept. is actually conserving space and reducing printing. So that’s win for the environment, right? www.nytimes.com/2025/12/09/u...

I found a 5 pack of #Solarcan from one of their first production runs, so I installed this Solarcan, serial #562 (normally the ones I buy are in the #30,000 or more) for a few weeks in the spring - just to see if it was still good.
3 #Solarcan were installed at the winter #solstice '24 at #lawrenceuniversity #Bjorklunden in Bailey's Harbor, WI. Collected after the summer #solstice The first is looking south at the Chapel. The second is facing the solar array, and the last one is in the woods near the solar array.
These two solargraphs came from an installation at Valley New School, looking East and South on College Avenue in Appleton, WI, installed around the spring equinox and taken down in May. #pinholephotography #solarcan #equinox
Here are a few Solarcan images I haven't shared yet. The first batch were taken from the roof of three elementary schools (Berry, McKinley and Richmond) in Appleton - installed in early January, and taken down in May to share with students. #Solarcan #pinholephotography #solstice

Installing a Solarcan pinhole camera between the winter solstice and spring equinox is a unique time in the N hemisphere, with no leaves on trees and the sun isn't too high, so it gets fully captured on paper #pinholephotography #solarcan The first image is from the Oconto river, from can #38,294
Here's a few @Solarcan Puck images from the windows at Valley New School in Appleton. They have some amazing views of downtown Appleton!
I've been working with 5th graders in a few elementary schools to install Solarcan Pucks around the school close to the spring equinox (facing North, South, East and West). Then they learned how to process and adjust the images to show the path of the sun over the course of a few days.
Last night was perfect snowflake photography weather in Green Bay. From the inside of my windshield.
A few @solarcan results from around the front yard, back yard, and down in the ravine (with a Solarcan Nebula). Front and back yard were installed in September, and the Nebula was installed in the summer. All started with trees full of leaves, eventually letting in more sun in the winter #solstice
Happy Solstice! I've harvested a few @Solarcan installations and installed a few more. More to come...
Snow squall to sun: This was difference in pressure from last night’s low of under 750 mmHg when the snow squall arrived, to today’s sunny high close to 770

Alum Brian Bartel experiments with long-exposure campus views
Brian Bartel ‘97, a science instructor and amateur photographer, developed a fascination with Solarcan, a method of shooting long-exposure photographs and capturing the sun’s journey across the sky.

It was almost perfect snowflake photography weather earlier today. A little too warm and now too windy.

Northern Lights pics from Thursday taken with a Pentax K-1, 10 second shutter, f-2.4 and various ISOs. We were just north of Appleton, so you can see a plane taking off from Green Bay.

Got to spend a little time with my dad taking pictures of a great horned owl family in City Park, Appleton and then a breeding pair of bald eagles across the river. There are two owlets and the mother visible. We can only see both eagles but not the eaglets yet.
With some help from new friends from the History Museum in Appleton, I installed some @solarcan.bsky.social pucks on the 4th floor of the Castle. The first solargraph is facing east at Lawrence University. You can see Main Hall on the right, and it looks like the sun is coming out of the Chapel.
I taped a couple @solarcan.bsky.social pucks to the sunroof of my car for a day or two, and love the output I get from driving around under the sun. Now those are maps!
