right now, I’m testing my half-built film holder. It’s outside in the sun with 2 strips of film, sitting at opposite ends to check for light leaks. If all goes well, I will start on the other side and maybe start on another holder or 2. The film holder has to be the most difficult piece of the puzzle so far. it has to be precise and light-tight. We’ll see how I do. I will be posting many more photos very soon.
