Some techno-addicts like to argue about new technologies and how they easily beat traditional arts; but the question is not so easy. Photography «took the place» of drawing art at the beginning of the 20th century, but in some way hand-drawn images still have some value. And at the end of the 20th century, with digital photography and image-processing software it became possible to combine easiness of photography with naturalness of pencil drawings.
If you think you need huge, complex and expensive packages, take a look at FotoSketcher: its small, easy to use and absolutely free!
FotoSketcher does only one thing: it changes any photo or picture in a way which completely imitates the picture drawn with «offline» (or real) pencils. And this «one» thing is done with the highest quality and greatest ease.
You just load your original picture, set some easy to understand parameters (or just leave them unchanged) and press «Sketch!» now wait a few seconds and voila! The software has a handy screen divided into «original» and «sketch» parts, so you can change parameters several times and examine the result.
Colour pencils or just black-n-white are imitated with the same ease. Now just print the picture with a high-quality printer and enjoy this old-fashioned «man-made» art!
