City Light Balance Guide
Settings for balancing ambient sky with artificial city lights
Early Blue Hour (first 1/3)
Sky still bright; ambient light balances with weak city lights
ISO: 100-400
Aperture: f/8-f/11
Shutter: 1-4 seconds
WB: 6000-6500K
Tip: Best for skyline shots where you want visible sky detail
Peak Blue Hour (middle 1/3)
Perfect balance between ambient sky and artificial lights
ISO: 200-800
Aperture: f/8-f/11
Shutter: 4-15 seconds
WB: 5500-6500K
Tip: Ideal time for cityscapes - sky and lights equally vibrant
Late Blue Hour (last 1/3)
Dark sky, city lights dominant; may need HDR
ISO: 400-1600
Aperture: f/5.6-f/8
Shutter: 10-30 seconds
WB: 4500-5500K
Tip: Great for light trails and reflections; bracket for HDR

7-Day Outlook
Twilight Definitions
- Golden Hour: Sun 0-6° above horizon - warm, soft directional light
- Blue Hour: Sun 4-6° below horizon - cool, even light, sky appears blue
- Civil Twilight: Sun 0-6° below - enough light to read outdoors
- Nautical Twilight: Sun 6-12° below - horizon still visible at sea
- Astronomical Twilight: Sun 12-18° below - sky dark enough for astronomy
- Night: Sun more than 18° below - true darkness
Blue Hour Photography Tips
- Tripod essential: Light levels are low; expect 5-30 second exposures
- Arrive early: Scout your location during daylight, set up before blue hour
- Bracket exposures: HDR helps balance bright city lights with dim sky
- Remote shutter: Avoid camera shake during long exposures
- Mirror lock-up: Reduces vibration on DSLRs
- White balance: Try 7000-8000K to enhance blue, or shoot RAW for flexibility
- Timing: Peak blue hour is often the middle third of the period
