Clunky Pinhole focus and tilt/shift test - and additional photos

When I went out to do my first field test of the Kodak Six-20, I also brought along Clunky, the Graflex pinhole, to do a little testing and shooting.  All of my pinhole images thus far have been on the soft side, and while I enjoy the dreamy look I'm getting, I was curious to see if adjusting the focus might make a difference on sharpness.  Up until now I had been shooting with the lens set to the infinity stops, and the infinity symbols lined up on the rails:

The next image was shot with the above infinity setting, and the image below that was shot with the arrow at the top pointing to the number 10.

While the second image is zoomed in slightly compared to the first, I didn't see any significant difference in the overall focus.  Here is a side-by-side comparison of a section of each image.

As I don't see a hugely significant difference, I will likely stick with the infinity setting in future shooting.

In addition to the focus, I was curious to see what result I might get from using the tilt-shift features on the camera.  I set the camera in a static position with my tripod and made three exposures of the same scene using each of the possible settings on the camera;

Shifting the lensboard to the highest position brought the view much higher, but it also cut the corners of the bottom of the film frame slightly.  The shot also came out lighter, which could either be because I lifted the pinhole out of the shade into more direct light, or the light reflects differently inside the camera body at this angle.

The tilted shot did not change the framing significantly, but it does seem like the foreground is in slightly sharper focus in the tilted shot as compared to the straight shot.

Beyond the focus testing, this outing was also an opportunity for me to run a roll of B&W through the new film back for the Graflex to see if the spacing on the winder is accurate.  I did get 8 evenly spaced shots on my roll, with a good lead on the film that would allow for color rolls to be loaded into a C-41 without fogging the first shot.  So this camera back is now designated as my color film back.

With the testing done, I used the rest of the film, along with a color roll, to capture some scenes around the gardens.
