OK! I scanned my nude woman and guitar playing monkey sketch and enhanced it in Photoshop. Huge difference. Compare it against the version I posted yesterday. That version was produced by taking a photo of my sketch.
I use the Auto Tone function in Photoshop to enhance my scanned sketches. That eliminates much of the color and texture of the paper and pumps up the black pencil lines.
This produces an incredible improvement in overall clarity.
Once again, I used a sketch by Amy Creshore at Little Hokum Rag as the basis for my sketch.
