Get the right camera settings for a tricky photo

Help me set up my camera for a specific kind of photo. Camera: [e.g. "iPhone 15", "Canon entry-level DSLR with kit lens", "mirrorless with 50mm f/1.8"] What I'm shooting: [e.g. "kids' indoor basketball game", "fireworks", "night city", "birds in my garden", "portraits at sunset", "the Milky Way"] Light conditions: [e.g. "dim gym", "bright midday sun"] Gear I have: [tripod / flash / none] Problem I keep getting: [e.g. "blurry", "too dark", "grainy", "background not blurred"] My comfort level: [auto only / semi-auto modes / full manual] Give me: 1. A starting point for settings: mode, aperture, shutter speed, ISO, focus mode, drive mode, white balance. For phones, the equivalent app modes and what to tap or lock. 2. Why each setting matters for this shot, in one line each (e.g. "1/500 s to freeze motion"). 3. Technique tips: where to stand, composition, timing, steadying the camera. 4. A troubleshooting table: Problem | Likely cause | What to change. 5. A 10-minute practice drill to learn this before the real moment. If you're unsure where a setting lives on my exact model, say so and tell me what it's usually called so I can find it in the manual. Remind me to ask permission before photographing people, and to follow rules at venues and events.
