What software can we use for painting, i mean that gives real effects like oil/water paint, sketching etc?

Corel Plumber 12 will be excellent pertaining to simulating healthy media, especially if you are using a artwork tablet-

You can basically figure out how to do the idea with any high-end bitmap editor for some points vector artwork program.Thus intended for sketching and also oil or pastel effects I would go with Photoshop Corel Catch the attention of or Gimp when for gouache plus pen effects We’d tend to look with Inkscape (preferred) Illustrator or even Freehand (because WHEN I hate Illustrator hence much).

Illustrator

Try Autocad, paint and photoshop

Corel Artist X

GIMP.
