Then from the top menu, choose Image then Adjustments then Threshold.
In the subsequent Threshold dialogue box, move the white Threshold Level slider to a position that produces the best effect - this will be unique to your choice of image.
This is my result using a 128 Threshold - I used the same setting (128), for my yellow flower photograph.
I removed the dark areas at the top of my image by changing the Threshold Level to 98.

artwork.
