His work is defined by a clear, structural approach to light and shadow. Unlike the sentimental, hazy scenes typical of his era, Rebell focused on the harsh clarity of the southern sun. He used a cool palette and sharp lines to define the rocky cliffs and architecture of the Amalfi Coast. His compositions often feature a low horizon line, which allows the sky and the quality of light to dominate the frame. This technique creates a sense of immense space and stillness, avoiding the cluttered elements found in traditional historical painting.

Modern collectors value Rebell for his ability to balance classical composition with a sense of realism. His paintings of the Italian coast offer a window into a pre-industrial Mediterranean world without falling into nostalgia. The architectural precision and controlled use of colour make these prints suitable for contemporary interiors that favour clean lines and natural light. His work functions as a calm, orderly window into a specific geographical moment, providing a sense of coastal serenity that remains relevant in a domestic setting.
