Thermography is a well know tool used widely for technical investigations of buildings, for archaeology, biology and arboriculture to name a few examples, and I was inquisitive to see how bonsai trees show up under a thermal image camera having used thermal imaging on trees before to assess health and to look for dysfunctional areas on trunks and along branches etc. The scale on bonsai is smaller than that of trees in their natural environments, but it is easier to image more of a bonsai at once. You don’t need to climb it to examine branches in more detail.
