His technique relied on a clear understanding of light and shadow. In works like Hermit in a Wooded Landscape or Landscape with River and Houses, he used etchings and oil paints to document the textures of foliage and terrain. Kobell often included figures such as travellers or cattle to provide a sense of scale. These elements appear as natural parts of the environment rather than forced additions. His work is characterised by a restrained use of colour and a focus on atmospheric perspective.

Modern collectors value Kobell for the quietude found in his compositions. His prints and paintings avoid the dramatic or the sentimental. They offer a direct connection to the natural world through a lens of calm observation. The muted tones and balanced structures of his work complement contemporary spaces that require a sense of order. His art provides a window into a rural past without relying on nostalgic or decorative tropes.
