Transform this image into Stipple Pointillism using individual black ink dots on white paper. Build darker tones through increased dot density and leave highlights sparsely dotted, keeping dots small, irregularly placed, and clearly separated where possible. Avoid continuous shading, lines, or regular grids. Keep the original subject and composition.
02Elephant in Starry NightAn elephant is depicted against a swirling blue sky inspired by Van Gogh. The elephant's skin uses stipple pointillism where varying dot density creates anatomical shading and texture.Raaaaelissa · CC BY-SA 4.0 · Wikimedia Commons03Stipple of John TolerA formal oval portrait shows John Toler in historical attire. The facial features and clothing are rendered through dense clusters of small dots, demonstrating tonal gradation.Unknown · Public domain · Wikimedia Commons04Erasmus Darwin.

Stipple engraving.Rahere is shown in prayer above a smaller scene of a reclining figure. Stippling is used sparingly to contour the face and create deep shadows within the monastic hood.Unknown · CC BY 4.0 · Wikimedia Commons08Saint Matthew. Stipple engraving.Saint Matthew is portrayed standing with an angel and a large book. Extensive stipple pointillism creates a range of values from the bright highlights on the robe to dark background shadows.Unknown · CC BY 4.0 · Wikimedia Commons09PSM V46 D622 Stipple patternA rectangular patch of abstract marks illustrates a stipple pattern. It provides a clear view of how individual small marks are spaced to create different levels of visual gray.Unknown authorUnknown author · Public domain · Wikimedia Commons10William Darling. Stipple engraving.William Darling is shown in a vignette portrait with a beard. The soft, feathered edges of the portrait demonstrate how stipple density can transition smoothly into the white paper.Unknown · CC BY 4.0 · Wikimedia Commons11Saint Luke. Stipple engraving.Saint Luke is depicted from behind, looking up next to an ox. The complex shadows on his draped clothing are formed by varying the proximity of black dots.Unknown · CC BY 4.0 · Wikimedia Commons12Alexander Eason. Stipple engraving.Dr. Alexander Eason is shown in an oval frame holding a document.
