相信很多人為選擇 iPhone 7 的時候
都是為了雙鏡頭而選擇 iPhone 7 plus
但目前實際拍攝起來的效果,沒有明顯改變
因為人像 portrait 模式(背景虛化景深效果)還未開放
今天 iOS 10.1 Developer Beta 1 開發者測試版推出
終於開啟人像模式的功能啦!相信正式版很快就會出來了
拿 iPhone 7 plus 的朋友再等一下下~
開啟方式:
人像模式是單獨的
如下圖右邊中間的黃字,要滑到「人像」才會啟用
https://pic.pimg.tw/iosmaster/1474540887-1972244707.png
啟用之後你會發現,畫面距離變很近,基本上是 2x 的大小
而且噪點也變多了,跟一般「拍照」的模式感覺有落差
所以在光源不佳的狀況下(尤其是晚上的時候)拍起來效果有點慘
另外要啟動景深效果的話,也要抓一下拍攝目標的距離
如果距離太近,畫面下方會顯示「離遠一點」
太遠的話,會顯示需在 2.5 公尺內
抓到了適當距離,就會出現黃底黑字的「景深效果」(如下圖)
景深效果會即時呈現在手機畫面上

要抓到適當的距離呈現景深效果,有的時候不太容易
尤其想要拍比較近、比較小的物體,很難抓
實拍照片:
以下照片皆在室內拍攝,沒有做任何調整,皆原圖輸出
「人像」模式下,每拍一張照片都會保存兩張
一張是一般的(上圖),一張是有做景深後製的(下圖)
若要看原圖,可直接連到我的 iCloud 相簿

上面這兩組可以看得出,景深效果會有前中後遠距加強的效果喔!
但是拍毛小孩的話,邊緣效果會把毛邊或鬍鬚淡化掉

上面這張最慘,拉拉的鬍鬚被吃光光嗚
其它靜物拍攝

總結缺點:
1. 鏡頭 Zoom in 變成 2x,要拍身邊的人物可能要後退
2. 噪點很多,光源不足或夜拍有點慘
3. 有距離限制,有時會抓不到想拍的效果距離
4. 快門會延遲 delay 約半秒
5. 毛邊的狀況下,主體邊緣效果不太自然
希望正式版可以改善以上問題或做更多優化
優點的部份:
1. 景深效果會即時呈現在手機畫面上
2. 拍攝後會保留原圖以及景深效果的圖,方便比較差異
3. 傻瓜也可以輕鬆拍出類似單眼的景深效果
個人心得:
雖然有待改進的缺點很多,但個人是非常喜歡這功能
光線不要太差的話,效果還是不錯的
稍微後製一下就可以很有 fu 了,覺得非常好玩 XDD
