This must have been the most difficult Photoshop photograph I have ever had to process! Not because of a particular challenging technique that I had to use, but because of the hypnotic arrangement of these tiles. Try looking at it for more than 20-30 seconds at the time and you’ll know what I mean! For those of you who are curious about the location, this is the ceiling over the tomb of Hafez, pictured here in its full glory.
