In this video on shoot like a pro, our series on helping you to improve your mobile phone photography, we're going to see how understanding light can improve your mobile phone photography.

我們的 "像專業攝影師一樣拍攝 "系列旨在幫助您提高手機攝影水準，在本視頻中，我們將介紹如何通過了解光線來提高手機攝影水準。

In the previous video we saw how by understanding the light and how by introducing a diffusion you can improve a portrait.

在上一段視頻中，我們看到了如何通過了解光線和引入散光來改善人像拍攝。

In this video we're going to see something similar again by understanding the light, how to improve texture in the video.

在本視頻中，我們將通過了解光線，再次看到類似的內容，即如何改善視頻中的質感。

Yes of course the weapon of choice is the same is the Oppo F11 Pro powered by the MediaTek Helio P70.

當然，Oppo F11 Pro 搭載的聯發科 Helio P70 也是一樣的武器。

Come with me.

跟我來

Now look at the light falling on this side of the pillar.

現在看看落在柱子這邊的光線。

The pillar has some structure on the surface and the light is exactly like how the light was falling in the first instance on Vishnu's face.

柱子表面有一些結構，光線就像最初落在毗溼奴臉上的光線一樣。

Let me take this shot.

讓我來拍

Okay now on this side of the pillar the structure is exactly the same but the Now see the difference between this and this.

好了，現在在柱子的這一側，結構是完全一樣的，但現在看看這個和這個的區別。

Both sides have similar structure but just the way the sunlight is falling on them making it look very different.

兩邊的結構相似，只是陽光灑在上面的方式不同而已。

This one looks flat, this one feels like it's got a lot of texture.

這個看起來很平整，這個感覺有很多紋理。

This will happen exactly the same way when you shoot people with costumes or dress with If you add texture purposely okay on layer them with clothes with some texture on it you will be able to enhance the look and feel of that image.

如果你特意添加了紋理，那麼你就可以在他們的衣服上疊加一些紋理，這樣就可以增強影像的外觀和感覺。

Let's see how we can do it.

讓我們看看如何做到這一點。

Okay so I think I will require Aditya and Mitt.

好吧，我想我需要阿迪提亞和米特。

Let me try with couple of our colleagues.

讓我和幾位同事試一試。

Okay let's get to the shot.

好了，我們開始拍攝吧。

Hi Aditya, Hi Mitt.

嗨，阿迪提亞，嗨，米特。

Can you come in front of this pillar?

你能到這根柱子前面來嗎？

Okay ready and you too.

好了，你也準備好了。

Yeah come there, stand there.

對，過來，站在那兒

Yeah nice, very nice.

是的，很好，非常好。

Okay now let me look at this image.

好了，現在讓我看看這張圖片。

Okay so this is interesting but we can make it a little more interesting by one adding a layer, second taking the light from you know from extremely you know fine angle.

好吧，這很有趣，但我們可以通過以下方法讓它變得更有趣：第一，添加一層；第二，從你知道的極細角度拍攝光線。

Okay ready so can you stand there?

好了，你能站在那裡嗎？

Can we have the jackets please?

能把夾克給我們嗎？

Aditya can you wear that and you wear this?

Aditya 你能穿那個，你能穿這個嗎？

Okay now you come back on the wall, one feet down.

好了，現在你回到牆上，往下一英尺。

Okay now look at this one.

好了，現在看看這個。

It's got so much of texture in it and it's got a different feel completely.

它的紋理非常豐富，給人完全不同的感覺。

Let me try and do the portrait mode here.

讓我試試這裡的肖像模式。

Let me get the focus on your faces, very nice.

讓我把焦點對準你們的臉，非常漂亮。

See take a look at this image.

請看這張圖片。

So let's go to the first one.

那麼，讓我們來看第一個。

This is how we shot.

我們就是這樣拍攝的。

Okay like a picnic shot.

好吧，就像一張野餐照片。

We added a layer and we moved to the portrait mode and see the kind of textures adding character.

我們添加了一個圖層，然後切換到肖像模式，看看這些紋理如何增添特色。

Okay it will look even better if we convert this into black and white.

好吧，如果我們把它轉換成黑白的，效果會更好。

So see that black and white.

黑白分明。

Now the black and white looks even better.

現在，黑白兩色看起來更漂亮了。

Hey thanks.

謝謝。

Now we will see how we can operate in the expert or the pro mode in low-light conditions because brightly lit conditions by and large is very safe but in low-light conditions mobile phone cameras behave a little differently.

現在我們來看看如何在弱光條件下使用專家或專業模式進行操作，因為在明亮的光線條件下基本上是非常安全的，但在弱光條件下，手機相機的表現就有些不同了。

And there the pro mode or the expert mode will help you to get better images.

專業模式或專家模式將幫助您獲得更好的影像。

Let's go and see that.

我們去看看吧。

For the demonstration of low-light photography I have identified a location inside our building reception.

為了演示弱光攝影，我在大樓接待處內確定了一個地點。

It's the mailbox room.

這是信箱室。

So this is the mailbox room which I want to shoot and demonstrate the low-light ability of this mobile phone.

這就是我想拍攝並展示這款手機弱光能力的信箱室。

And this is not exactly the light we have in this room.

而這並不是我們這個房間裡的燈光。

It's much darker.

顏色更深了。

For you know filming purpose we are using an LED light bounced on the ceiling which will go off.

為了便於拍攝，我們在天花板上裝了一個 LED 燈，它會熄滅。

We'll switch it off while taking the shot.

我們會在拍攝時把它關掉。

So let me explain the setup for this shot.

讓我來解釋一下這次拍攝的設置。

I'm using a selfie stick to hold the camera up and I'm using the headphones to trigger.

我用自拍杆舉著相機，用耳機觸發。

You can also use a Bluetooth you know trigger or you can use the self timer in the camera.

您也可以使用藍牙觸發器或相機中的自拍定時器。

But I've decided to use a headphone to trigger the camera.

但我決定用耳機來觸發相機。

Okay so I'm going to be shooting in three modes.

好了，我要用三種模式拍攝。

First is auto mode which which is what the camera would decide for you.

首先是自動模式，這是由相機為您決定的。

Second is the night mode which is kind of an intelligent mode which is in the camera.

其次是夜間模式，這是相機中的一種智能模式。

And third is the pro mode or the expert mode.

第三種是專業模式或專家模式。

And we will compare these three images and see how they kind of compare and how they match up.

我們將對比這三幅影像，看看它們是如何比較和匹配的。

Okay into the shoot.

好了，開始拍攝。

Let me set up the camera.

讓我來安裝攝像頭

Okay I'm going to get set the levels right.

好吧，我去把電平調好。

Okay so the camera is set.

好了，相機已經設置好了。

The first shot I'm going to take is in auto mode.

我要拍攝的第一張照片是在自動模式下拍攝的。

Aditya can you switch off the light.

Aditya 能把燈關掉嗎？

Okay now this is the kind of light that we have in this place.

好了，這就是我們這裡的光線。

Ready standing by and I'm going to take the auto.

準備就緒，我要去開汽車了。

Okay and now let me go to the night mode.

好了，現在讓我進入夜間模式。

Okay night mode is decided by the camera and it will do its own thing.

好吧，夜間模式由相機決定，它會自己做自己的事情。

So I have no control over it.

所以我無法控制。

Let me take the shot.

讓我來拍

So as you can see the camera is shooting multiple exposures and then trying to put it together using a software which is inside the camera app.

是以，正如您所看到的，相機正在拍攝多次曝光，然後嘗試使用相機應用程序內的軟件將其組合在一起。

Right now we are in expert mode.

現在我們處於專家模式。

Okay can you switch on the lights please.

好的，請把燈打開

In expert mode you have two controls to yourself.

在專家模式下，您有兩個控制按鈕。

One is the ISO, second is the shutter speed.

一是 ISO，二是快門速度。

Okay ISO behaves a little differently in each situations.

好吧，ISO 在各種情況下的表現略有不同。

All ISO speeds are not a guarantee for good quality images.

所有 ISO 速度都不能保證影像品質。

Especially when you shoot low-light situations.

尤其是在弱光環境下拍攝時。

A higher ISO will also bring in a lot of noise.

較高的 ISO 也會帶來大量噪點。

A lower ISO is preferred.

最好使用較低的 ISO。

When you lower the ISO you also have to lower the shutter speed.

當您降低 ISO 時，您也必須降低快門速度。

Hence I'm using a stand.

是以，我使用了支架。

Currently the 900 as the ISO and this camera can go to 100 ISO which is something which I will prefer.

目前的 ISO 值為 900，而這款相機的 ISO 值可以達到 100，這是我比較喜歡的。

Now at 100 ISO the camera is asking you to shoot at 1 by 10 of a second.

現在，在 100 ISO 下，相機要求您以 1/10 秒的速度拍攝。

Not really.

其實不然。

I think I have to shoot at probably at one second.

我想我大概要在一秒鐘內完成拍攝。

Okay let me take that shot.

好吧，讓我來拍。

The camera is steady.

相機穩定。

Light off.

關燈。

Ready.

準備就緒。

Nice.

不錯。

Okay now we should compare two images.

好了，現在我們應該對比兩張圖片。

Can we switch on the lights?

我們能開燈嗎？

We're going to compare these three images now.

我們現在來比較一下這三幅影像。

Now let me look at the shot that we took first which is the shadow area and try to you know enlarge it.

現在，讓我先看看我們拍攝的照片，這是陰影區域，並試著放大它。

You will see lots and lots of grains here.

在這裡，你會看到很多很多的穀物。

Okay let's go to the next shot.

好了，我們來看下一個鏡頭。

It's nice and bright.

又漂亮又明亮。

In fact a little brighter than what I would have preferred.

事實上，比我希望的還要亮一些。

But everything is so smooth.

但一切都很順利。

So artificially smooth and so basically what the camera has tried or rather the software has tried is to soften all you know not so good like grains etc.

是以，人為的平滑和相機所做的嘗試，或者說軟件所做的嘗試，基本上就是弱化所有你所知道的不太好的東西，如顆粒等。

They've really softened it.

他們真的把它軟化了。

Now to the shot that we took manually using the expert mode.

現在來看我們使用專家模式手動拍攝的照片。

Okay it's clean if you notice.

好吧，如果你注意到了，它是乾淨的。

Okay go to the darkest area where you are likely to find grains.

好吧，去你可能找到穀物的最黑暗的地方。

Even that area is clean.

就連那個區域也很乾淨。

Okay we shot at one second.

好的，我們在一秒內拍攝。

Okay and now let me try two and a half second.

好的，現在讓我試試兩秒半。

Even at two and a half seconds you can't really.

即使是兩秒半，你也無法真正做到。

Lights please.

請開燈

You can't really find any grains in the image.

影像中找不到任何顆粒。

Let me show you a few more examples.

讓我再舉幾個例子。

Okay lights off.

好吧，關燈。

Okay virtually no light here.

好吧，這裡幾乎沒有光。

Shooting in auto.

自動拍攝

Okay the next one is the night mode.

下一個是夜間模式。

Okay and now the expert mode.

好了，現在進入專家模式。

In expert mode the idea is to get the lowest ISO and let me give a three second exposure.

在專家模式下，我的想法是使用最低的 ISO 並進行三秒曝光。

Oh Two words about this camera.

關於這臺相機，我只想說兩句話。

Well the Oppo F11 Pro has 48 megapixels in the rear camera.

Oppo F11 Pro 的後置攝像頭像素為 4800 萬。

The main camera.

主攝像頭

Imagine two bars of chocolates both of same size and weight.

試想兩塊同樣大小和重量的巧克力。

One has 12 pieces in it and the other has 24 pieces in it.

其中一個有 12 個棋子，另一個有 24 個棋子。

Even though one of them has 24 pieces in it technically you are not getting more chocolates but you're going to spend more time trying to break 24 pieces and in almost all mobile phone cameras are the same.

儘管其中一個有 24 塊，但從技術上講，你並沒有得到更多的巧克力，而是要花更多的時間去打碎 24 塊，而幾乎所有的手機攝像頭都是一樣的。

But here they are packed in 48 megapixels.

但在這裡，它們的像素卻高達 4800 萬。

Okay which means the camera must have a very powerful processor to process all that digital signal that is coming into the processor.

好的，這意味著攝影機必須有一個非常強大的處理器來處理所有進入處理器的數字信號。

Quickly process it and show it to you as image which can be viewed.

快速處理並顯示為可查看的影像。

Because the digital signal by itself cannot be viewed.

因為數字信號本身無法查看。

So it's important that the camera also have a very high quality fast processor which is exactly what the MediaTek Helio P70 does.

是以，重要的是，相機還必須配備高質量的快速處理器，而這正是聯發科 Helio P70 所能做到的。

Very interesting feature which this phone has and we have not tried is the front-facing camera which keeps appearing while you're doing the selfie.

這款手機有一個非常有趣的功能，我們還沒有嘗試過，那就是在自拍時不斷出現的前置攝像頭。

But we didn't try that because I'm not really fond of doing selfies.

但我們沒有嘗試，因為我不太喜歡自拍。

Who knows we'll do another session entirely based on how to shoot selfies.

誰知道我們會不會再做一次完全以如何拍攝自拍照為主題的課程呢？

Bye for now.

再見。

I almost forgot in our earlier videos on mobile phone photography we got tons of requests asking us to you know give more information on photography and when are we starting our classes on photography etc.

我差點忘了，在之前關於手機攝影的視頻中，我們收到了大量請求，希望我們能提供更多關於攝影的資訊，以及我們什麼時候開始攝影課程等等。
