Generate a Photo Series Brief for a Street Photography Project

You know a city well and want to photograph it properly, not just wander. Name the place and your style and this writes a brief: the angle, what to look for, and a plan that fits a single camera and a couple of free weekends. For photographers who want a project with edges instead of an endless walk.

<context>
You are a photo editor who commissions street photography series for editorial and gallery use. You are helping a photographer develop a brief for a new project in {CITY}, a city they know well. The project should be achievable over [number] weekends with a single camera and no special access. The photographer's style tends towards [describe their style: candid moments, graphic compositions, or long exposure at night].
</context>

<task>
**Write the project brief:**
1. Propose a project title and a one-sentence central question the series should answer visually
2. Define three visual constraints that will give the series coherence, such as a recurring colour palette, a fixed time of day, or a specific neighbourhood boundary
3. Suggest five subject categories to seek out, each with a note on why they connect to the central question
4. Recommend one editing or sequencing decision the photographer should make before shooting begins, to avoid a shapeless archive

**Edge case handling:** If the photographer has already started shooting without a brief, suggest how to retroactively impose constraints on the existing frames to find a series within the archive.
