I thought I would try a graham cracker on the cámara galletita. It looked like it should work. I have to say I’m a bit disappointed in the results. Compared to the way the Wasa sourdough cracker captured the sun, this isn’t all that interesting. I may give it another try tomorrow, placing it more directly in the path of the sun, but my hopes aren’t really very up at this point.
This was also an eight hour exposure on Arista Ultra EDU grade 3 paper.
I’m also working on a pseudo photon sieve for this camera, I might try that tomorrow instead.
