Celebrating 6 Months with an Illusion
Well, I’ve been doing this blogging thing for six months now. Of course I still feel like an absolute newbie at it. I still have no idea what draws people here in the first place. The Feedjit and ClustrMap widgets give me an idea, because they show how many people landed on my site and where they came from.
For example, yesterday there were 54 visitors, but an average day has more like 12 visitors. My best day was over 200 visitors. I honestly don’t know what causes those spikes, but I plan to continue learning and experimenting.
This week we are finishing up a discussion of value in the Visual Literacy class. This illusion by Edward H. Adelson perfectly illustrates the concept of value relativity. Placing dark values near light values make them appear darker, and the reverse is true when we place light values near dark values. In the illusion, square A appears darker than square B because of value relativity, however both squares are of equal value. Don’t believe it? Read more about it here or just print the image out and cut out the squares. You’ll see they are the same color of gray!
