I took my Speed Graphic out for a walk around town yesterday afternoon to practice using it with the Polaroid packfilm back. It's a clunker, and old cameras always have their quirks. The shutter is sluggish at slower speeds, and the rails are a bit chewed up, which can cause difficulty with focusing and closing up the camera. The lens plate had light leaks I had to patch up, and the packfilm back was also leaking due to the disintegration of the felt strip in the darkslide slot. The leaks were not a big deal with slow (~ISO 100) film, but with the Fuji FP3000B they were a major problem.
But at home before I went out I did some experimenting and found the horizontal angle of view for a vertical orientation regular packfilm exposure to be about 34°. I used this knowledge (and the scale on my tripod) to take a four-exposure panorama of the Herron St bridge that connects Lawrenceville to Polish Hill:
Lawrenceville to Polish Hill
This was taken with Fuji FP3000B film, which is a bit tough to shoot with in the Speed Graphic in daylight – it's so fast that I often have to max out the shutter speed (1/500) and aperture (f32). But I bought a whole case of it for cheap, so it's getting used regardless.
I'm still trying to get a hang of framing shots with the Speed Graphic and the Polaroid back, which is smaller than the 4x5 exposure area of the camera. It's especially tough when playing with tilt and shift. I find myself frequently switching to the ground glass to frame a shot, and even then not being totally successful.
I also took some Impossible Polablue (not a huge fan of this film) and Impossible Chocolate (one of my favorite films):
