Interview in a mixed-light living room with 25 minutes left
You are shooting a 4-minute interview with a retired teacher in her living room for a community YouTube channel. The room is 3 m × 4 m. Daylight comes through a large window on camera-left; two 60 W tungsten bulbs and one fluorescent tube are on. The camera is a DSLR with a 50mm f/1.8 lens, no ND filter, and the only audio is the camera's built-in mic. The subject wears a white cotton kurta and sits 1.2 m from an off-white wall. The camera is set to auto white balance and auto exposure. On the monitor, the window side of her face is blown out, the other side is muddy, and there is a hard shadow of the camera operator on the wall behind her. A ceiling fan clicks every 4 seconds. The room's mains socket is two-pin and the extension board has no surge protection. You have one white A4 sheet, one black chart paper, a bedsheet, and 25 minutes before the subject's next appointment.
1. Diagnose the exposure, colour, lighting and audio problems and decide the order in which you would fix them in 25 minutes. Justify the order.

Diagnosis:
- Exposure: auto exposure is averaging the bright window and the darker room, so the window side clips and the shadow side is underexposed. The white kurta makes clipping more likely.
- Colour: daylight from the window is roughly 5600 K; tungsten bulbs are about 2800–3200 K; the fluorescent tube adds a green cast. Auto white balance is chasing a moving mix.
- Lighting: the window is acting as a hard key from camera-left, producing a blown highlight and a dark opposite side. The operator's shadow on the wall shows the light is not controlled and the subject is too close to the background.
- Audio: the built-in mic picks up room echo, fan clicks and camera handling noise; it is too far from the subject.
Order in 25 minutes:
- Safety and power first (2 min). The two-pin socket and unswitched extension board are a shock/fire risk. Use the socket only for low-draw items, keep cables away from the walking path, and do not overload the board. If the board is damaged, stop using it.
- Audio before performance (5 min). Switch off the ceiling fan, close the window if traffic noise is worse, and move the camera to about 1.5–2 m with a tighter frame so the built-in mic is closer. Record 20 seconds of room tone. Audio is the hardest thing to fix later.
- Exposure and colour (8 min). Switch to manual exposure and manual white balance. Expose for the white kurta so it is bright but not clipped, then let the shadow side fall where it may and fill it.
- Lighting control (8 min). Diffuse the window with the bedsheet, flag the wall with the black chart, and bounce with the white A4 sheet. Move the subject slightly away from the wall.
- Final check (2 min). Record a 15-second test and check headphones if available.
Rationale: safety cannot wait; audio and exposure must be set before the subject starts speaking because she has a hard stop.
2. Describe the specific lighting and camera settings you would use with only the materials listed, and explain the trade-offs of each choice.

Camera settings
- Set the camera to 25p if available, shutter at 1/50 s, ISO 400–800, aperture f/2.8–f/4. The 50mm lens on a small room will be tight; frame a medium close-up rather than a wide shot.
- Use manual white balance set to daylight (about 5600 K) because the window is the main source. Turn off the tungsten bulbs and the fluorescent tube if they are not needed; mixed colour cannot be corrected cleanly across the face.
- Use zebras or the histogram to protect the white kurta. Do not rely on auto exposure.
Lighting with the listed materials
- Window as key: tape the bedsheet over the window to soften the daylight. Trade-off: the bedsheet cuts light, so you may need ISO 800 and a wider aperture, which reduces depth of field and may add noise.
- White A4 sheet as bounce fill: place it on the shadow side, just out of frame, to lift the dark side of the face. Trade-off: it is small and weak; it will soften but not eliminate the contrast.
- Black chart paper as a flag: place it between the window and the off-white wall to stop the hard operator shadow and reduce spill on the background. Trade-off: it may create a darker background edge, so check the frame.
- Move the subject away from the wall: 1.2 m is too close; even 1.8 m reduces the shadow. Trade-off: the room is small, so the camera may need to move back and the lens may include more of the room.
Audio: with only the built-in mic, get the camera closer and keep the fan off. Trade-off: a tighter frame and a warmer room. Accept that the sound will be 'YouTube acceptable', not broadcast quality.
3. What would you tell the subject and the channel owner about the limitations of this shoot, and how would that affect the promises you make about the final video?

Tell them before shooting, not after. To the subject: 'We have 25 minutes and one small camera. I will keep the framing tight and the fan off. You may feel warm, and we may need to stop once to check the sound. Please speak a little slower and avoid rustling the kurta near the mic.' To the channel owner: 'This room has mixed daylight and tungsten, a hard window and a camera mic. I can make a clean, natural-looking interview for YouTube, but I cannot promise studio colour matching or broadcast-grade sound.'
Promises to make: a completed 4-minute edit with clear speech, corrected exposure, a consistent colour look, subtitles if required, and one round of minor revisions. Promises to avoid: 'cinematic', 'broadcast quality', 'noise-free', or 'we will fix the fan clicks in post' unless you have actually tested the audio. Built-in mic recordings often contain room echo that noise reduction cannot remove without making the voice sound metallic.
Offer a fallback: if the audio test is poor, ask to record a second take with the subject closer to the camera, or propose a later shoot with a lavalier. Put the limitation in writing in the message confirming the shoot. Managing expectation is part of production, not an apology at delivery.
