Making a Projector from a Camera

One thought I had about lighting the Temple at night was to use projected images of trees. The idea was to use found, made, and donated images of single trees in various seasonal states, projecting multiple examples at once onto the Temple. It would create the illusion of real trees even more than colored lights. I initially dismissed the idea of getting slide projectors running, but I figured I could repurpose 35mm cameras, reversing the design and shining images through the lenses.

I picked one up at a thrift store for a few dollars and took it all apart. It was a basic viewfinder camera, fully automatic with a zoom. The lens was integral with the body and was all motorized. I figured out how it basically worked, then was able to adjust both the focus and zoom. (Side note: although it seems to have infinite adjustment, there are only a fixed number of zoom levels, since the motor that does the zoom also does the focus: moving a small amount adjusts the focus, but going some fixed number of turns changes to the next zoom level.) I glued and taped mechanisms so the shutter stayed open and the aperture was as wide open as possible.

I had a 10W LED I had wired up for a different project so I thought I'd give it a shot. With the camera back open, I taped an old slide where the film would have gone. It seemed so poetic and perfect that a camera—one that would have taken the pictures I intended to use—would act as a projector. I was able to project and image, but it was too dark to use—even despite using such a high-brightness LED.

Quitting a Third Time

Speaking with Jenn about the Frederick Douglas autobiography audiobook she's listening to, I had an epiphany: I should stop trying to do things that I'm not good at and refine things I am good at. It's not so much defeatist as it is hopeful: I want to know how this whole "living" thing works. I want to live life well—to be good at it. I decided to quit the Temple project. In a matter of days, the Black Rock Arts Foundation will make a request for "Letters of Intent" to apply for an art grant. I might be able to make the temple; I might not. But what is it going to do—to prove? Rather, I want to focus on projects closer-to-home—something I'm good at already and can get better with practice.

Learning 3D

I decided I needed to learn a 3D rending software. I found Blender which is Open-Souce, and, hence, free. I read a bunch about the user interface and found it quite daunting because it was unlike any software I had used. Well, it was like all the software I had ever used, just mashed-up in a way I hadn't encountered yet. In 2 hours I had made it through most of the tutorial to make a gingerbread man and had a better understanding of how it worked. I was rather elated at the progress I had made. I recalled what it was like to learn something new and get good results—the kind of thing that fired my obsession with computers in my teen years.

Second Small Model

I was reinvigorated to work on the temple again. I want to make a structure that is so appealing (visually, emotionally, and otherwise) that nobody will want to burn it. And I want to integrate the community so they are fully invested in the project.

I drew some more sketches, trying to focus on the appearance of the end product rather than being fixated on the ability to construct it. I started in on making a model again. I took a couple 2×4's and hot-glued them together for a "trunk". Then I needed something to make branches. I was looking for inspiration outdoors when I decided to use some sticks from my magnolia tree. I cut them and glued them on then added bamboo skewers as branches and small scraps of paper as the "leaves". For some kind of scale, I added Vince.

I basically built 1/4 of the tree and took some test photos against a colored backdrop. I had four photos, each with the model rotated 90 degrees—all set up with the same camera settings on a tripod. Then I pulled it into Gimp, did a rough removal of the colored background and composited the four rotations on top of one another to create a pseudo-representation of a full model. I added a photo of the Playa from Vittorio Carli's to make it look like it was at Burning Man.

Burning the Model

Tuesday got rained out so I went to Antoni's in the afternoon with some stuff. He had built most of the 1:6 (e.g. "Barbie scale") model and we finished up the remaining bits.

It looked really good although he didn't have time to finish putting a skin on the third quadrant, and didn't even assemble the fourth. We put together the fourth and tried burning it. It went okay although it collapsed organically like a structure. I had tied it together with rope but the quadrants weren't weighted enough to topple and didn't fall over when the rope burned through.

Jay Lincoln Sketches

I met with Jay Lincoln, a local artist and teacher at a coffee shop. He drew sketches for me and we worked on it. It was during this meeting that the project fully became collaborative.

Jay suggested adding outriggers to hold up the long spans of the branches—perhaps to appear like ladders, or if the branches touched the ground. I insisted the branches be free-standing, though … unless, of course, it proves impossible to do so. He had the idea of integrating ladders and stairs into the minor branches which would be fine by me.

Quitting and Rebirth

Yesterday I was sure the project was completely dead. I had nobody who was helping me. I created a model and sent photos to both Antoni and Brandon and received no response at all. But today I decided I would have to do it all myself, although I figured I should find someone to help with sketches.
