His style balances formal portraiture with everyday observation. In works like "Een vrouw die gevogelte verkoopt", he records street life. His portraits of figures like Joachim Rendorp demonstrate a clear attention to texture and costume. Regters used light to define the space around his subjects. He avoided the heavy shadows of the previous century. He preferred a softer palette and clear, even lighting.

Collectors today value Regters for his documentary quality. His paintings provide a window into the professional lives of 18th-century Dutch citizens. The small scale of many of his works makes them suitable for modern interiors. They offer a sense of historical character without the scale of state portraits. His work captures a moment of quiet confidence in Dutch history.
