In every wood in every spring
there is a different green.
This is a section of a picture I took last week on my morning walk:
I used an Olympus D-510 camera, which is really pretty old at this point.
What I was hoping to capture here were the many fine shades of green in the treeline. The nearest trees are along a stream, and the willows really stood out to my eyes as being different from the other trees. The willows are the short trees with a kind of blurry look because their leaves are so very small. They also looked a trifle duller or more olive than the other trees: their leaves are also on the greyish side, and they generally change color early.
So why are all the greens in this photo so dull or brownish to my eye? Is it something about
- My monitor? Each monitor is different, though I can look at plenty of other landscapes and see all the green my eyes desire.
- My eyes (or maybe my visual cortex)? I know that I have a very strong preference for green, it "stands out" for me more than it does for at least some other people. Not counting my husband, who is slightly colorblind: he can *see* red and green, but he doesn't *notice* them, they're kind of dull, nearly-brown colors for him. Among other things, this means that the classic philosophy question, "When I say 'red', am I having the same sensation as when you say 'red'?" has a known answer for us: "No."
...and now I just spent a bunch of time unsuccessfully looking for an online test for tetrachromacy to give the Sprogs.
- My crappy camera? This strikes me as extremely likely. Does anyone have a suggestion for a *good* point-and-shoot digital camera that costs under $100? No point spending more while Moore's Law is in force. Also, I'm pretty terrible at taking pictures these days, because I need separate glasses for near and distance vision -- so I can look at the world, or look at the camera's screen, but not both.
