关于7,我是用PS2调的,用的是一个Vintage效果的action,是从网上下载的(在
FLICKR里用Vintage做关键词可以搜到很多),我是电脑菜鸟,每次只按运行就OK了。
具体的Action步骤如下,版上学计算机的牛人很多,可以自行设计:
01.Open Image
02. Duplicate Image (LAYERS > DUPLICATE LAYER) and rename (LAYERS > LAYER
PROPERTIES) to SEPIA.
03. Select SEPIA layer and go to (ADJUSTMENTS > SEPIA)
04. Uncheck SEPIA layer to hide layer for now.
05. Select BACKGROUND layer
06. Go to (ADJUSTMENTS > HUE / SATURATION) and set SATURATION to 115

你说"等效光圈->进光量->画质 这每一步都不对"
等效光圈->进光量 解释清楚了, 下面看进光量->画质
"总通光量决定画质的好坏"确实需要一个限定条件, 我昨天已经补充了, 就说在光线不
充足的情况下, 换句话说就是photon总量不足以saturate sensor. 在这种情况下"总

It depends. There are many scenarios (e.g., shooting most events, doing
documentary) in which color could be distracting, and you may want to lower
the saturation and/or contrast, or convert your pictures to B&W, in order to
prevent color from being the subject. On the contrary, there are many
cases in which color itself would become a good subject and you want this
particular subject to have enough saturation/contrast.

r+g+b, if I understand correctly, is very close to what you call intensity, although in a more careful definition it might be weighted sum.
The Hue, Saturation, Brightness system is somewhat different from what I am
describing(rgb). The saturation, if I remember correctly, is basically a kind of ratio
of colorness and whiteness. However, the colorness there is given in terms of
a relative fraction, whereas the r,g,b numbers given above are absolute.

solid fats can be manufactured from oils by converting animal or vegetable
oils by passing hydrogen through the oil in the presence of a nickel
catalyst, under controlled conditions. The addition of hydrogen to the
unsaturated bonds results in saturated bonds, effectively increasing the
