My first example(s) are from a roll of purple tinted Lomography film but they are here primarily because they were exposed through a 30 mm lens.
Oh, let's first set the foundation for the discourse of "wide angle" lenses. For this post I will include lenses 38 mm and wider as wide angle. As a contrast to the "standard" focal length of 50 mm (what the eye sees). And I'll include the common focal lengths 45 and 42 mm lenses in the "standard" category.
Back to the 30 mm lens. It is quite a rare focal length, as far as I know. This one was made by Meyer-Optik Görlitz for Praktica cameras in the 1960s. I bought it with a defunct camera at Plastac Retro in Gothenburg.
The routine wide-angle photograps produced with our smartphones are now the standard. In my view they are too wide. And they often distort what's in the picture. That's why I keep using these old cameras. I most often like to take more "narrow" pictures but at the same time make experiments with cluttered subjects. It's an ongoing search.
What's a good photograph?
