Welcome to my post-processing galleries. I will gradually show some aspects of post-processing of digital images.
I enjoy processing as much as taking photos, often more, as that's where the captured image is transformed into the final result and is invariably improved in some way to realise more of its potential.
As a starter, it's interesting to consider the checkerboard shadow illusion in the first gallery below from Professor Edward H. Adelson, Professor of Vision Science at MIT. For more on the professor and his work, including more illusions, go to Professor Adelson's home page.
To find out about this illusion and what it might mean for us in the real world, open the image.
