Review Photographing Collectibles: Review Notes
This is a working guide to review photographing collectibles for new collectors: what the terms mean in practice, where the money goes, and which details are worth paying attention to.
Light Damage Is Cumulative
UV breaks polymer chains in paint binders and clear coats; the damage shows first as lost gloss, then as yellowing, and it is irreversible. This is why a piece can look perfect for two years and dull by year four without anything ever touching it — the light was doing the work the whole time.
Plan Numbers
| Constraint | Target |
|---|---|
| Footprint | ~25 × 25 cm |
| Vertical envelope | ~65 cm |
| Per 180 cm shelf | 6 comfortable |
| Extra depth for LIN | +5–8 cm |
Plan the Footprint First
A quarter-scale bust needs a footprint near 25 × 25 cm and a vertical envelope of about 65 cm, covering the roughly 32 cm piece plus base clearance and open air above the head. Measure the shelf and photograph the tape measure against it so the number is real, not remembered.
Lux-Hours, the Budget Nobody Tracks
Museums manage light as a dose: illuminance multiplied by hours. A shelf at 200 lux for eight hours a day is about 584,000 lux-hours a year. Halving daily on-time is as effective as halving brightness, and cheaper, because a display shelf does not need to outshine the room it stands in.
Source Comparison
| Source | UV | Heat | Verdict |
|---|---|---|---|
| Direct sun | High | +10 °C | Avoid |
| Halogen 50 W | Yes | +10–15 °C | Avoid |
| Warm LED 2700 K | <0.1% | Very low | Best |
If the specification is vague, treat that as the answer. Good manufacturers publish the detail because collectors ask for it.
