This curve shape merely means that 127A, which is about as frequently seen in the real world as a batting average above 1.000, will become something like 110A, which is no more common than a seven-run homer.

You don’t have to worry about these areas of the curve, because they’re far out of the gamut of anything you’ll ever output to, and even if they weren’t, they cover brilliant reds and yellows, of which there are none in this particular photograph.

So, the point one gridline down from the center point covers the horse, which started at 25A.

Since that point doesn’t change from its original position, the magenta-asopposed- to-green component of the horse won’t change either.

The background looks better, but all I have to say is, that’s a godawful stupid-looking horse.Horses are supposed to be brown, not orange. In Figure 4.5A, he averaged 51L25A39B—substantially yellowish red, yet not absurdly so. That got changed to 54L46A56B, totally out of hand.

在图4-5A中，其平均数是（略）——完全是黄红色，这太可笑了。把它修改为（略），完全失去控制。
