The author of this tutorial is Tatyana Fedorova.
This tutorial is created in Adobe Photoshop, but you can do the same in any other photo editor compatible with AKVIS Sketch plugin. The author also used the same image in a tutorial for AKVIS ArtWork.
AKVIS plugins give one a fantastic opportunity to get a phenomenal mixture of art and photography multiplied by the power of the computer and the intelligence of software. For my first experience with AKVIS I choose the AKVIS Sketch and AKVIS ArtWork plug-ins. Everything is so quick and easy. Keep up your excellent work!
