Through the magic of Photoshop, we now can transform any photograph into a truly realistic color drawing with these simple steps. The values of the tools and filters are up to you and each artist may have his own.
Fine, let's begin...
1. - We open the photo of a woman working and we duplicate it. (onto a separate layer)

2. - Apply the poster edges filter with the values indicated to convert the image into lines and planes.

3. - Open the "stylize" filter menu and select diffuse as in the example.

4. - Make the layer "merge visible".

5. - Apply to this layer a Gaussian blur with the value shown.

6. - Change the layer to multiply and lower the opacity by 20%. We can see that the image is a fairly realistic, professional drawing, right?

7. - Finally, flatten the image.

8. - Compare the image to the original and we can appreciate the result.

That's all, friends, and remember: if I can do it, you can too.
A hug,
