His style is defined by a strict adherence to Realism. Krohg used a direct, unembellished technique to portray his subjects. In works like The Net Mender (Garnbinderen) and Fisherman, he captured the weathered textures of skin and clothing. He preferred close-cropped compositions that create a sense of proximity between the viewer and the subject. This technique makes his portraits feel immediate and honest.

Modern collectors value the authenticity found in Krohg's paintings. His focus on honest labour and everyday moments provides a grounded aesthetic for contemporary interiors. These prints offer a connection to historical maritime traditions through a lens of documentary-like precision. The neutral palettes and strong character studies suit spaces that require a sense of history without unnecessary ornamentation.
