第一次試PS exposure blending,俾d意見！

個前景有啲偏藍

作者: WuSoLo 時間: 2013-8-8 07:02 PM

的確是偏藍了，有原圖嗎？

exposure blending

混合曝光有咩作用,係玩乜野架? 請指教.

應該是類似 HDR 的東西吧？

原圖

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。

約以個入觀感來說，比較喜歡第一幅。

The first orginal picture looks much better and nature.
The second one have no taste. Looks like cartoon.
Thx

呢張冇加exposure同contrast。只係balance咗colour。會唔會好d？

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.

作者: ob51330 時間: 2013-8-9 10:46 AM

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.

我都係啱啱試，冇資格教。而且張相都唔係blend得幾好！

作者: united806 時間: 2013-8-17 01:20 PM

第一張雖然偏藍. 但其他比我的感覺係. 很不自然.
樓主係咪想場景的大部份細節都想睇到, 先會變成甘?
如果係我做的話, 某d部份應該黑暗的. 只會適中的提高光度.
回億返當時眼睛所見的光暗度. (相機的寬容度跟肉眼比較非常有限)
唔好意思, 大家研究下.

1st time trying photoshop? consider very good.
my comment: take note on the blending part, especially when u paint the mountain. some top of the mountain (left size) are too dark. My suggestion is to shoot with "HDR" then merger will be more nice. and u foreground too bright. My view.

Thanks for your comment and it is constructive.

Yes, I mountain tip on left is brushed a bit dark. Need to take more caution next time,

I tried HDR before, but I personally don't like to HDR effect as it is too artificial. Blending effect is more natural!!!!
