I have just played around with hue and saturation
1) removed the white background with magic wand selection tool.
2) made multiple duplicate layers of the flower.
3) changed the hue and saturation settings of each layer with different unique values.
4) scaled all flowers to fit in the canvas and arranged them in a circle.
5) finally flattened the image and adjusted the level to make the blacks more blacker (5 years and 1571 days ago)
