紅米NOTE4X 應該可能是目前能用HDR+中最便宜的機型吧！？
所以很好奇HDR+能提升到什麼地步～
網路上對紅米NOTE4X相機一面負評（實際上也的確是啦～）
下面來看看HDR+的威能吧～
以下範例順序皆為 原廠相機=>HDR+=>100%細節對比
所有照片都沒有經過任何後製，全部直出～
我挑了一些一般人生活上會拍到的場景～
Redmi NOTE4X should be the cheapest model which can use HDR + now!
I'm curious HDR + can upgrade to what level~ Let's take a look at HDR +
The following example is the original model => HDR + => 100% details of the comparison All the photos have no retouching ~
I picked some of the scenes that ordinary people would take.
首先看幾個易用性對比，同樣移動速度的電梯上拍照～
左邊HDR+因為較快的快門速度幾乎沒有手震～
顏色也更突出，沒有去雜訊後飽和度降低的情況～
First ,take pic in the same speed of the elevator ~
The left HDR + is almost no hand shake due to the faster shutter speed The color is more prominent.
同樣是移動的電梯上拍前面２個型男～
使用HDR+較穩定而且過曝的地方也完整保留了細節～
HDR + is more stable and hold the details of highlight ~
這是百貨公司地下停車場，２者ISO差不多，快門HDR+快許多～
在ISO大於800的情況下，note4x的原廠相機去雜訊都會讓你搞不清楚到底是手震了還是去雜訊太重導致糊掉了…
HDR+最顯清晰度跟動態範圍都提升超多～
This is the department store underground parking, two ISO almost, HDR + shutter is much faster ~ In the case of ISO over 800, the stock camera's noise reducing will make you confused is this hand shake or noise reducing too heavy ... HDR + significant upgrade the dynamic range ~
書店的小擺飾，右邊連木質都變高級品的感覺…
左邊原廠就是暗淡許多
Bookstore small ornaments, the right side of the wood have become high-level feel ..
夜晚隨拍的豪宅～ 左邊HDR+整個顏色鮮明～
銳利度及動態範圍都遠勝～
Night with the mansion ~ left HDR + looks great ~
Sharpness and dynamic range are far better ~ Left the original is a lot of dim
同樣快門，右邊原廠ISO還更低，但整個畫面質感原廠像是廉價的相機～慘…
The same shutter, the stock camera use lower ISO , but the whole picture texture like a cheap camera ...
幾乎是極弱光環境，差異很大無需多言～
Extreamly low light~ you can see the different~
這邊要說一下HDR+有三個模式，一個是”關”一個是”auto”一個是”on”
在我這個版本下，auto跟on是完全不一樣的２個模式～
auto單純就是多幀合成及視情況提升暗部＝＞因此快門及ISO跟原廠相機接近
on是以短曝光合成並調整亮、暗部～ ＝＞快門會快許多，ISO可能較高或低不一定
視情況選用２種簡直不得了～！！
這張的HDR+是開 auto 並對亮部測光～ 可以看到會自動提亮暗部
看參數HDR+快門更快，ISO更低，但畫面亮度跟原廠卻差不多多～ 細節還更好
真的是神演算法～！！！！！！
In this case ,switch HDR + to "auto" and the metering highlight ~ It'll automatically brighten the dark .
Accordign to the Exif. HDR + use faster shutter speed and lower ISO lower, but the brightness is almost the same with the stock camera ~ better details
HDR+增加了曝光，減少了雜訊並增強對比～像是打了光一樣～
完全難以想像是同環境光線…
也…感想同上
下面這個比較有點不同～
原廠相機 Stock camera
HDR+
G5使用HDR+
中間Note4x的HDR+已經提升很多了，但跟G5一比還是弱了很多～
完全就是CMOS體質上的差異了～
一比才會知道G5的CMOS真的不錯～
註：G5那張還有縮80%方便對比
The middle one is Note4x .HDR + has been improved a lot, but right side G5 is better ~ G5 CMOS is really good ~
Annotationi: G5 goes 80% to facilitate comparison
打烊的攤販
Closed vendors
細節遠勝 better detials
HDR auto純色區塊雜訊去得很不錯～
顏色也都保留住～
HDR auto 's noise reducing very good ~ The color is also retained ~
傍晚後原廠真的幾乎不能用…畫面髒細節流失嚴重…
After evening, the stock camera is hardly use ... loss lots of details ...
這也是幾乎是note4x能拍的極限弱光環境了～
自己看囉～
自己看囉～
結論HDR+讓紅米note4x相機可用性上升了好幾個檔次
以我評估應該會比iphone７還要好～
紅米Note4x相機弱項解決後，可望正式成為CP值最高的手機XD
Conclusion:
HDR + makes the redmi note4x camera usable . I think it's better than iphone7 ~
It can become the highest CP of all smart phone XD
