Claude is the right choice when you want to compare multiple lighting moods and get a clear opinion on which works best for the intended use — whether that is a calm bedroom, an energetic kitchen, or a welcoming entrance hall.

Steps

Once connected (see setup above), use the Interior Design tool:

  1. Share the room photo and describe the lighting mood you want — for example, 'warm evening with soft lamplight and no overhead fluorescents'.
  2. Ask Claude to run `change_lighting` via the interior-design tool.
  3. Review the output and ask Claude what is working and what is not.
  4. Request a second lighting mood for comparison — brighter task lighting, daylight, or dramatic accent.
  5. Choose the version that best matches the space's purpose and save it.

Example Prompt

Try this with Claude using the Interior Design tool
Use interior-design with change_lighting to shift this dining room from its current flat midday look to a warm, intimate evening atmosphere with candlelight and soft pendant lighting. Give me the render and tell me which lighting setup would suit a dinner party most.

Tips

  • Describe the feeling you want, not just a technical setup — 'cosy and inviting' gives better results than '2700K warm white'.
  • Compare a daytime and evening version of the same room to see which photographs better for your listing.
  • Use Claude's critique to decide if the lighting change alone is enough or if you also need a colour or furniture tweak.
