Computer usage has blurred the distinctions between illustrators , photographers , photo editors , 3-D modelers , and handicraft artists. Sophisticated rendering and editing software has led to multi-skilled image developers. Photographers may become digital artists . Illustrators may become animators . Handicraft may be computer-aided or use computer-generated imagery as a template. Computer clip art usage has also made the clear distinction between visual arts and page layout less obvious due to the easy access and editing of clip art in the process of paginating a document, especially to the unskilled observer.
