"Pop Art" Photoshop tutorial. Here is the before:

The steps:
Open a photo you would like to edit. Resize (Image> Image Size) the image to the output size you would like. It is fine to upscale a low resolution image before using this effect. Duplicate the layer (Layer> Duplicate Layer or Ctrl+J) and change the blending mode of the new layer to Luminosity.With the top layer selected, Invert (Image> Adjustments> Invert or Ctrl+I).Reduce the opacity of the current layer to 50%.Press Ctrl+Shift+Alt+E to create a new layer of the visible and delete Layer 1.Activate the Background layer and duplicate the layer (Layer> Duplicate Layer or Ctrl+J). Move the new layer to the top.Change the blending mode of the new layer to Multiply. Select the top layer and open the Threshold tool (Image> Adjustments> Threshold). In the Threshold tool, drag the input slider towards the left or right to adjust the effect. Or if the default value of 128 is good enough, simply click OK.
Finally, we`ll increase the saturation as the final effect to create this pop art.
Select the middle layer and use the Hue/Saturation tool (Image>Adjustments>Hue/Saturation or Ctrl+U) to increase the saturation.
