Ryder specialised in the stipple technique, a process using thousands of tiny dots to build up tone. This approach allowed for subtle transitions in light, which is evident in his engraving of S. Kelly's Castle on the Blackwater. He focused on the structural accuracy of Irish landmarks while maintaining a soft, atmospheric quality. His prints capture the specific geometry of ruins through careful variations in dot density.

Collectors today appreciate Ryder for his restrained style and historical accuracy. His work avoids the sentimentality often found in later topographical art. These prints function as honest records of the Irish countryside in the late eighteenth century. Because they use a monochrome or limited palette, they integrate easily into modern rooms that favour understated decor.
