I’ve often seen and heard of the classic moiré pattern but rarely have I photographed it on purpose. Such was the case as I viewed the netting in a local nursery. I knew strange patterns would be captured on my phone camera. It was all I had at the time although I’m finding that I use this camera more and more. Anyway…You won’t actually see this illusion with your eyes when viewing it in the real world. Our brains are quite adept at filtering out mathematical oddities and illusions. However tonight when reviewing a couple of of photos taken with my iPhone, it became clear that I had indeed captured a classic illusion. It’s strange how the camera captures images in distinctly different ways than how we actually view a scene. The more experienced we become at knowing and exploiting these differences, the more we can accurately capture images as they really are. I was originally taken a little bit by how the overhead netting in the nursery diffused a perfectly beautiful Spring sky like so…I liked the way the netting rolled off into the distance Ina series of waves. But look again, it’s the moiré that I noticed and perhaps next time you photograph a screen or some other finely patterned object you may well see the same sort of illusion and so now you know what it is. Further explaination is found below if you are so inclined. Moiré is discussed fairly often in photographic literature especially I equipment and lens reviews and such. And yes, the nursery itself was quite lovely as you can see here…
We all love a nursery 🌞
More on the interesting phenomenon of moiré:
In mathematics, physics, and art,moiré pattern (/mwɑːrˈeɪ/; French: [mwaˈʁe]) is a secondary and visually evident superimposed pattern created, for example, when two identical (usually transparent) patterns on a flat or curved surface (such as closely spaced straight lines drawn radiating from a point or taking the form of a grid) are overlaid while displaced or rotated a small amount from one another. For a real visual check out this link. Warning, it’s not easy on the eyes yet it is interesting.
