Abstract
High-end digital cameras can make several artistic representations by replacing their lenses to several special effects lenses. However, they requires high level skill and knowledge. Also, they are expensive for amateur camera men. Thus, software filters to enable fisheye and macro lenses' effects are proposed and developed, as plugin of picture editing software. Fisheye effect by orthographic projection algorithm, vignetting, and color change functions were implemented. As macro lens effects, area selection and depth of field change functions were implemented.
