It's interesting how similar the zoomed in version of these two textures are despite the zoomed out ones looking very different (i.e. the smooth appearance of the Macbook vs the brushed aluminum's clear lines). Deep down, the difference is subtle and just is some white lines of pixels between the other pixels. It shows how even small differences in the textures can result in a very different overall appearance.

I'm wondering how the speaker was able to take the super zoomed in image, is it with some special camera? I tried to observe this effect with my phone camera, but of course it doesn't have the same level of zoom. And even if you do have the zoom, wouldn't you just see more defined bumps??? So, what kind of technique did the speaker use to get the "colorful" tiny images???
