Professional Photography: lighting, editing and clients

Copy this, open Claude, paste it, and Claude will walk you through the lesson step by step.

For a grown-up: Claude is for adults (18+). Copy this, paste it into Claude, and use the answer to explain the lesson to your child.

I'm learning "Professional Photography: lighting, editing and clients" on The Future Market. Lesson 1: "Light as a system (read it before you shape it)".

What the lesson teaches:
- Quality of light: a small light source relative to the subject gives hard light with sharp-edged shadows. A large source relative to the subject gives soft light with gentle shadows. Moving a light closer makes it effectively larger and softer.
- Direction: front light is flat, side light shows shape and texture, back light creates rim glow and separation.
- Inverse square law: light gets weaker quickly with distance. Doubling the distance from the light to the subject leaves about one quarter of the light.
- Light ratio: the difference in brightness between the lit side and the shadow side. A small ratio looks gentle; a big ratio looks dramatic.
- Read exposure with the histogram: a graph of dark to bright tones. Bunched against the right edge means highlights may be clipped (lost); bunched against the left means shadows may be clipped. In RAW you can recover more from shadows than from blown highlights, so protect highlights first.
- Colour temperature: warm (orange) light from bulbs and sunset, cool (blue) light from shade and overcast. Mixed colours in one scene need a decision: gel, switch off one source, or choose one to match.

The exercise I'm working on:
Photograph one subject with one lamp at four distances and directions. Label each photo hard or soft, front, side or back, and write one sentence on which you would use for a portrait and why. ---

I'm stuck. Please:
1. Explain the main idea in plain, simple words with one everyday example.
2. Walk me through the exercise one small step at a time. Ask me what I've done so far before giving the next step.
3. Don't just give me the final answer. Help me do it myself, and check my work when I share it.

I'm a parent helping my child (about 8 years old) with a lesson called "Light as a system (read it before you shape it)" from the course "Professional Photography: lighting, editing and clients".

Here's what the lesson says:
Light is like water from a tap. A small tap close to you feels strong. A big tap far away feels gentle. A pro decides how big the tap is, how far away it is and where it points.

The activity:
Photograph one subject with one lamp at four distances and directions. Label each photo hard or soft, front, side or back, and write one sentence on which you would use for a portrait and why. ---

Please explain this so an 8-year-old understands: short sentences, a fun everyday example, and no hard words.
Then give me 3 simple questions I can ask my child to check they understood, and a way to do the activity together, one tiny step at a time.
