a rough drawing representing the chief features of an object or scene and often made as a preliminary study, a tentative draft or a brief description (as of a person) or outline.
There were 3 main types of sketches:
- Coquis’. A coquis’ was intended to remind the artist of some person or scene he wished to remember in a more permanent form – they were not necessarily for a finished product.
- Pochade: A rough or quickly executed sketch or study.
- Portrait Sketch.
Digital painting sketch: is an emerging art form in which traditional painting techniques such as watercolour, oils, impasto, etc. are applied using digital tools by means of a computer, a graphics tablet and stylus, and software. The artist uses painting techniques to create the digital painting directly on the computer. Digital art is a term used to describe art that is made or presented using digital technology.
