I'm trying to recreate this effect in Photoshop (attached image); does anyone recognise the effect, and know how to recreate it?
It could be a halftone. To do something similar:
Convert the document to grayscale, using
Image › Mode › Grayscale.
Convert the document to a bitmap, using
Image › Mode › Bitmap.
Set the method to halftone.
- Set the shape to line.
Convert back to RGB, by choosing
Image › Mode › Grayscalethen
Image › Mode › RGB Color.
Add a gradient map. :)
