Grimshaw's style and subject matter changed little during his career; he strove constantly to perfect his own very individual vision. He was interested in photography, and sometimes used a camera obscure to project outlines on to canvas, enabling him to repeat compositions several times. He also mixed sand and other ingredients with his paint to get the effects he wanted. Even though he established no school, Grimshaw's pictures were forged and imitated in his lifetime, notably by Wilfred Jenkins and H. Meegan.
Although his moonlit town views are his most popular works, he also painted landscapes, portraits, interiors, fairy pictures and neo-classical subjects.
Grimshaw's primary influence was the Pre-Raphaelites. True to the Pre-Raphaelite style, he put forth landscapes of accurate colour and lighting, and vivid detail. He would often paint landscapes that typified seasons, or that typified a kind of weather. By applying his skill in lighting effects, and unusually careful attention to detail, he was often capable of intricately describing a scene, while strongly conveying its mood. He died of cancer in 1893.
