Or: fooling around with image processing kernels.
Edge fit + bw cutoff:
Partition into multiple bw images and taking Laplacians:
Plain Laplacian + bw cutoff:
High frequency removal by partitioning into multiple bw images:
Sexy dark high frequency removal:
Subtracting low frequencies from original image:
Overshooting Laplace central element (does this filter make me look old and cracking?):
And yet, throughout the whole process, she just keep smiling.
