I saw this on the web, and was wondering if anyone have some experience on how to do it! It might be a well-known effect but I have no idea about it.
Traditionally I've always heard such art called Contour Drawings.
It's merely a series of lines that follow the contour of a shape.
There's no automated method in any application to create this which I'm aware of. However, Applying a series of ever-expanding lines is a fairly easy thing to do in Adobe Illustrator.
In fact, with the proper set up, you can merely use a blend in Illustrator to create all the lines in one step.
- I would say Op Art
- Shutterstock/Google say Concentric Oncoming
- In the book Principles of Two-Dimensional Design by Wucius Wong it's called Concentric Repetition
1 - Add a White Stroke aligned outside:
2 - Add an Outside Black Stroke Effect to the layer:
3 - Duplicating the layer, change the Shape Stroke Width on each lower layer:
