Does anyone recognise this effect? Is it half toning?

Question

I'm trying to recreate this effect in Photoshop (attached image); does anyone recognise the effect, and know how to recreate it?

Answer 1

It could be a halftone. To do something similar:

1. Convert the document to grayscale, using Image › Mode › Grayscale.

2. Convert the document to a bitmap, using Image › Mode › Bitmap.

3. Set the method to halftone.

4. Set the shape to line.

5. Convert back to RGB, by choosing Image › Mode › Grayscale then Image › Mode › RGB Color.

6. Add a gradient map. :)
