Here's how:
1. Open the lotus photo and copy the background layer.
2. Remove color and adjust color levels to increase black and white contrast.
3. After inverting, perform Gaussian blur, and then perform Filter-Brush Stroke-Splash.
4. Create a new layer, set the layer blending mode to color, and use a pink brush to color the lotus.
5. Add some text as you like, stamp it, and it’s done.
