His approach to religious subjects, such as Saint Philip and Saint Bartholomew, relies on these tonal shifts. Kininger often placed his figures against dark backgrounds to define the physical presence of the saints. In his series of the apostles, including Saint Andrew and Saint Matthew, he uses strong contrasts to build form. His work on the Transfiguration demonstrates his ability to handle complex compositions with a focus on clarity and classical structure.

Modern collectors value Kininger for the moody atmosphere of his prints. His use of deep blacks and soft greys creates a contemplative feeling that suits minimalist or traditional interiors. These works offer a sense of historical weight without feeling cluttered. The clear lines and dramatic lighting in pieces like Saint James Major make them effective as standalone art or as part of a gallery wall.
