Fotosynthese...
... der Gräser. Die auf einer Wiese unter Vorhandensein von Wasser und Sonnenlicht in Sauerstoffradikale und Peroxide umgesetzte Lichtenergie entwickelt eine starke Bleichwirkung. Das kann man bei der "Rasenbleiche" ausnutzen. Die schönen alten Leinenhandtücher werden wieder weiß wie Schnee!
... der Fotografie. Derselbe Sonnenstrahl, der das Leinen auf der Wiese bleicht, mogelt sich gerade in das Objektiv der #Lochkamera. Die Bleichszene wurde aufgenommen mit einer #CameraObscura aus Papier. Das nenne ich mal Fotosynthese :)
This photo had some interesting distortion in the upper left. I’m left wondering if the film wasn’t taunt or if the camera wasn’t as level as I thought it. #pinhole#fp4party#believeinfim
1/ This is the longest exposure I've ever taken: 8 months long! It shows the Sun's path on the sky between Apr 17 - Dec 11 2018, as seen from ESO's Paranal Observatory in #Chile.
This is part of a collaboration with Diego López Calvín, an expert in solarigraphy: https://solarigrafia.com
Diego sent me some of his hand-made #pinhole cameras, which I placed all over Paranal. So what do we see here? See thread below 👇
For all those #ScienceFiction#Writers ou there, here is an #AllternativeHistory#AlloHistorical change that could produce interesting results - what if Taylor Swift's current interest, Travis Kelce, was not a NFL player. Consider the Swift impact on other lesser appreciated activities that Kelce could have chosen.
For Example:
I'm sure there are other possible endeavours that don't have as wide a public following as the #NFL that could have acquired The #Swifties enthusiastic attention. 😂
So back in March I set up an @thesolarcan puck on a shed in my back garden facing towards my house. It recorded every sunset when the sky was clear, reflected by the windows of my home! You can also see a couple of ghostly tripods where I set up telescopes for solar observing! #pinholephotography#pinhole#NewZealand#solarcan
I'm getting an idea for a new #3dprintedlens. As before with the #stereography lens, it wouldn't be fully printed. I'm thinking of making a #pinhole#photography#lens. This morning I tried a moderately sized pinhole and a random positive lens from a projector and it worked. The pinhole made a blurry image, the lens corrected the image. From experience I know that both the lens and the pinhole need to be at their particular spots. I just need to get approximate dimensions and then adjust.
