Most pinhole images are made using a pinhole that is very close to- or at the optimum size for- the chosen focal length and in most cases this is a good choice for general photography: it lets you get the best quality image a pinhole can produce. That being said, while testing the PinZonie I have been experimenting using pinholes that are in some cases up to 2 stops more open or closed than the optimum setting and really liking the creative options it gives me.
As I always say… experimentation is key!
