CORE RULES

• North-facing window (northern hemisphere): consistent cool soft light all day — ideal for portraits and products
• East window: warm morning light; West window: warm afternoon light; South: harsh direct midday risk
• Window size equals source softness: larger window = softer wrap, smaller = more directional
• Shadow side is the creative space: fill ratio determines drama vs. beauty
• Curtain/diffusion doubles the effective source size, reduces color temperature slightly
• Camera angle relative to window changes everything: face the window for flat fill, side-on for form
• Dust motes and window bars add visual texture — use intentionally
