應該是類似 HDR 的東西吧？

減少藍色，加了小小紅色和綠色，加了小小exposure和contrast後

exposure blending 一般用於高反差的環境，例如日落。部份景物不能正確曝光。用多張不同曝光值的相片合成，令景物正確曝光。原理和HDR差不多，但比HDR自然。

我是用PS的Layer Mask做的。

It just don't look nature.
I still like your orginal picture better.
Tell us why you want to change a good picture into a alter picture?(from nature into un nature)
If you have a special occasion/special effect is ok.
Say when we taking picture, we try to us the nature light if it allow. If not then we use flash light/or add flash as fill in.
Nature light, because it is nature.
That is my personal thought.

When you say original, do you mean the first in #5 thread? or the one in #1 thread?

The challenge is that in High Dynamic situation, either the foreground is under exposed when the sky is correctly exposed or the sky is over exposed when the foreground is correctly exposed.

I did not bring GND when taking this picture.

would it be better if you use a black card for the too bright sky so that the foreground becomes good.

Actually, there are different ways of handling High Dynamic exposure. Of course, black card is one of them. But you will need to consider the successful rate. Indeed, it is very difficult to use black card in a windy environment, like TaiMoShan.

GND is also any way, which can be used in most situations.

HDR and exposure blending are post production.
