Catching the moire

I took this photograph mostly because I saw this gentleman lying beneath the palm either reading or taking pictures with his cell phone. The lens was probably set to f/5.6 or f/8.0 and it was rather quick grab. Little did I know that I actually caught a very healthy specimen of moire... Look for yourself...

Of course at this small size it is hardly visible at all. Below is the screenshot of my LightRoom 4.3 showing this photo at 1:1 scale... Pretty much the same kind of moire is visible when this image is exported as is at full resolution...

I wouldn't draw any conclusions at this time, but this manifestation of the moire certainly attracted my attention...
