Of course, the object of having a Pinhole Camera is to make genuine
pinhole images - tilted (maybe), light leaks, blurs, strange patterns etc.
However, as a user of some fine lenses, it is always 'grounding'
for me to see what happens to a pinhole image if just a small
amount of post-production is applied. Here, I have straightened
the image, added a little contrast, 'smart' sharpened @ 50% (as I do with
any of my film scans from the finest lenses), cropped out the
fuzzy edges, and 'dodged' the fountain a touch. Grounded.

Here's the original straight scan.
