### Full prompt
```text
A photographic comparison series in a four-panel grid demonstrating the optical effects of changing aperture values at [f/1.8, f/2.8, f/10, and f/14]. Each panel captures the same [gentle, beautiful woman] in a portrait shot with a [Canon 85mm prime lens], standing against a [city skyline during blue hour just after sunset]. The panels progress from extreme shallow depth of field with creamy circular bokeh lights at f/1.8, to moderate background blur at f/2.8, to increasingly sharp city architecture and distinct details at f/10 and f/14.
