Summary

[edit]
Description
Eesti: Inimese peatäi (Pediculus humanus capitis) pildistatud mikroskoobi all kasutades 3,5x objektiivi. Pilt on tehtud 2024. aasta märtsis. Pildil on selgelt näha, kuidas parasiit on kinnitunud juuksekarvale. Tänu peegelduvale valgustusele on eriti hästi näha täi keha segmendid ning iseloomulik pinnatekstuur koos karvakestega. Pilt on tehtud musta tausta peal, mis toob hästi esile putuka kehaehituse detailid. Valgustamisel on kasutatud peegelduvat valgust fotograafia välklambilt (speedlight), mis rõhutab eriti hästi isendi välispinna struktuure. Pilt on tehtud kasutades fookuse virnastamise tehnikat (focus stacking), mis tagab suure teravussügavuse.
English: A human head louse (Pediculus humanus capitis) photographed under a microscope using a 3.5x objective. The image was taken in March 2024. The picture clearly shows how the parasite has attached itself to a hair shaft. Thanks to reflected lighting, the body segments of the louse and its characteristic surface texture with setae are particularly well visible. The specimen was photographed against a black background, which excellently highlights the details of the insect's morphology. The lighting technique used was reflected light from a photographic speedlight flash, which particularly emphasizes the surface structures of the specimen. The image was created using focus stacking technique, which ensures great depth of field throughout the subject.
