Summary

edit
Description
Deutsch: Digitalfoto, Fischaugenkonverter 0,25x (Typ: flächentreu). Raum und geradezu eine Wand (3 Wände, Decke und Boden sichtbar).

Bild unbearbeitet.

Eine Versuchreihe ergab die beste Qualität bei einem etwas größeren Abstand zwischen Vorsatz und Smartphone. Deshalb habe ich nicht den selbstklebenden Ring verwendet, sondern einen Sockel mit 4 mm Dicke plus einem Neodym-Ringmagnet mit 3 mm Dicke, insgesamt 7 mm.

Zentrumkoordinaten und Abbildungsfunktion (weiter unten) wurden für die Umrechnung in andere Projektionen verwendet (siehe Dateiverwendung).


English: Digital photo, fisheye converter 0.25x (type: equisolid angle). Room and straight ahead a wall (3 walls, ceiling and floor visible).

Image unprocessed.

A series of experiments showed the best quality at a somewhat greater distance between converter and smartphone. That's why I have not used the self-adhesive ring, but a socket of 4 mm thickness plus a neodymium-ringmagnet of 3 mm thickness, in sum 7 mm.

Center coordinates and mapping-function (see below) where used for remapping into other projections (see File usage on Commons).
