In recent years, mobile phone photography has become stronger and stronger, and various brands have taken turns to take the first photo. But it's also a scene taken by this camera. The light collected by this CMOS, the data processed by this chip and the first camera are firmly grasped by the iPhone and have never been surpassed. The root cause may be that 1986, Jobs invested100000 USD to enter CG industry. Since then, Apple has always had the technical background of making video images, and with the development of the times, its strength has become more and more profound. In 2007, Apple introduced the ProRes video coding standard, and a few years later it became one of the general standards in the advertising film industry. In 2020, iPhone began to support HDR video shooting. In 202 1 year, with the arrival of Dolby Vision 8.4 standard, the whole process of HDR was truly realized, and the related production and viewing thresholds were reduced to an affordable level.

This article will talk about what iPhone 13 Pro did for us when shooting HDR video, and how to make better use of this new mobile phone to shoot Vlog, so that the powerful hardware strength can play a good role.

This article has more than 3800 words, so it is suggested to skip to the part of interest for reading.

What is HDR?

HDR is a term relative to SDR (standard dynamic range), which is called high dynamic range. The difference between HDR and SDR is that HDR supports a wider dynamic range and can better present the details of light and dark parts in the picture.

In order to make everyone understand better, here are two pictures to explain.

The brightness range of SDR is only 0-100nits, that is, the color scale from the darkest to the brightest in the picture is only 1000 layers, while the brightness of objects in the real world can reach above1000 nits casually.

The result of this numerical difference in video shooting is that when shooting a scene with large light ratio and strong contrast between light and dark with SDR standard, the bright part will be overexposed if the details of the dark part are preserved, and the dark part will die black if the details of the bright part are preserved (as shown in the left picture); Under HDR standard shooting, the image can retain wider dynamic range data, so the details of bright and dark parts can be preserved (as shown in the right picture).

In addition to the brightness range, HDR standard also brings richer color display, which can no longer be limited to BT.709, and then display BT.2020 and so on.

Presumably, everyone has a preliminary understanding of HDR standard now, so I won't go into details about the introduction of HDR standard. Interested friends can go and see for themselves, and we will continue.

Advantages of mobile phone shooting

Before the mobile phone supports HDR shooting, compared with cameras with dynamic range of 12 and 13, it actually has no great advantage. But now we have an iPhone that can support both HDR shooting and HDR monitoring, and even the iPhone has a certain HDR post-production capability, which makes the HDR standard move from paper to reality, and also popularizes this tall technology with a very low operating threshold. To everyone who owns an iPhone.

Among the traditional cameras, the model supporting the shooting of BT.2020 color gamut (PQ/HLG) is only equipped with an old LCD (thanks to Sony: Who are you? ), users have no idea what they took, let alone how to make it more beautiful. The most powerful thing about mobile phones is not the volume that everyone praises, but "what you see is what you get". The screen above 6 inches is directly aimed at the camera that needs an external display, and HDR live view directly costs tens of thousands of cameras+Ninja V recorder combinations.

What Apple is best at is to deconstruct what it takes for granted, find the essence of the problem and solve it in a simpler and more direct way.

Film effect

The most anticipated function of iPhone 13 series is the movie special effects mode, which can blur in real time and switch the focus of post-editing. This technique is very common in some narrative scenes.

Although the smart recognition object of the mobile phone is very strong, sometimes the focus switch is not the time we want, and this problem can be solved perfectly through post-editing (because I shed happy tears every time I roll the focus again).

time-lapse shooting

The iPhone's time-lapse shooting function is very powerful and easy to use. Actually, there is nothing to say. However, there is one place that needs special attention. Be sure to lock the focus and exposure before time-lapse shooting (long press the focus object).

Lens transition

Iphone 13 Pro (and 12 Pro) series has been upgraded to three cameras. During the recording, we can also switch shots by clicking the button. This process of lens switching will be recorded, and a short lens push-pull effect will be automatically generated.

Using this effect skillfully, we can seamlessly splice shots taken at different times and in different modes, for example, suddenly turning video into time-lapse photography.

Night scene shooting

Starting from iPhone 1 1, it supports long exposure in dark environment, which brings great benefits to mobile phone photographers. iPhone supports intelligent correction of small-scale jitter caused by hand grip. In fact, it is much better than all kinds of body image stabilization and lens image stabilization, which really realizes hand-held shooting of night scenes.

Mini tripod

In daily Vlog shooting, because the video anti-shake function of the mobile phone is getting stronger and stronger, the mobile phone stabilizer is not a necessity. But in most shooting scenes, the mobile phone is not in a handheld state, but needs a tripod to fix it. I recommend buying a mini tripod here, which is compact, easy to carry and especially easy to use.

This mini tripod was a good price for squatting a few years ago, and it is guaranteed by 6.9 yuan. Is it worth it? Friends in need can pay attention to the relevant news in the station themselves, and there are many such products.

External radio

Although the radio performance of the iPhone is very strong now, at some time, we may still need a comprehensive stereo acquisition device, such as we want to record the live band, the laughter on the deck of the cruise ship and the noise of the night market crowd. At this time, using stereo recording can bring an immersive experience to the audience. In addition, through the conscious sound collection in the early stage, we can use extraordinary ambient sound to render the atmosphere in the later video clips, thus improving the impression of the film.

Here I recommend IQ6/IQ7, a well-known audio acquisition equipment brand ZOOM, which is an XY stereo condenser microphone for mobile phones, which is a portable recording device in human words.

This is the old version of IQ6, and the new IQ7 will have more functions. This device is very simple to use, just plug in the light interface of iPhone and you can start working. The product also has an adaptive application called "HandyRec", which has many settings about recording, even EQ, reverberation and so on.

Anti-fall protective shell

The author thinks that using iPhone 13 Pro as the main camera to shoot Vlog video is a powerful protective shell against falling, because there may be many accidents in the shooting process, and the mobile phone is easier to fall than the camera, which leads to screen explosion and affects shooting and mood.

The author chose the small anti-fall color shell determined by the defensive color. The appearance of the protective shell is not as exaggerated as other three-proof shells, and it is more exquisite and beautiful, and its anti-fall and anti-seismic performance is also very good.

This small color shell adopts the design of the fourth generation multi-ap anti-fall system. The frame of the whole protective case has been raised, which is higher than the design of the mobile phone body as a whole. In addition, there are safety buffer airbags around, and there are even extra buffer ribs at the four corners.

The striking gradient design around the back of the case is actually made of alloy material, which can absorb the impact of the accidental drop of the mobile phone.

Throw one before it's too late.

external power source

As mentioned earlier, after the release of Apple's MagSafe Ecology, the MagSafe magnetic charging treasure replaced the position of the original iPhone back clip battery. In daily use, this device saves an annoying cable and can be fixed by itself, which brings great experience to users. Without affecting the use of mobile phones, you can keep the power anxiety away from yourself.

The author chose Mommie's "Q.MAG POWER Magnetic Wireless Mobile Power Supply", which is certified by Apple MFi and can be charged with lighting wires, which is very convenient.

In addition, the capacity of this magnetic power supply is 7200mAh, so theoretically, it is no problem to charge two iPhones13 Pro from 0. In addition to the wireless charging of 10W, there is also a wired PD bidirectional fast charging with USB-C interface, and the wired charging speed is 20W, which perfectly adapts to iPhone 12/ 13, giving users the choice of wired wireless charging, and can also charge other devices.

As mentioned earlier, after the release of iPhone 13 Pro, many MagSafe magnetic power supplies will fight with the lens module, shielding each other and winning many brands in backstab. The magnetic power supply of this Momis in my hand is not a problem, which is just avoided on iPhone 13 Pro.

Che pai che chong

The above mentioned road beat and moving delay in the car. Here, the author uses the combination of Belgin's magnetic wireless car charger and cheap bracket.

After MagSafe entered the field of vehicle charging, it perfectly realized the functions of bare metal and shell-less wireless charging and the use of the bracket at the same time, cut off the tedious process of plugging and unplugging the charging cable, and simplified the process of installing the bracket for the mobile phone. The whole charging action is done in one go, which is very enjoyable.

Belgin's wireless car charger supports 360-degree rotation, which can not only unlock horizontal navigation, but also enable the author to realize a very important part of go on road trip Vlog recording, and shoot the road along the way.

Fast charge correlation

Although MagSafe wireless charging is very comfortable, it will be more reassuring to use wired charging when the power is urgent, especially when eating in the middle of shooting and resting in the hotel at night. If possible, we use 20W wired fast charging, which is faster than 5- 10W wireless low power charging. Moreover, this place is generally equipped with a power socket, and the external power supply is used to restore the full power state of your equipment and escort the next shooting.

The current 20W fast charging head is as small and portable as the 5W fast charging head handed down by Apple before. The author chose the 20W square drill from Momis.

The three-dimensional size is only 30x30x30mm (not counting pins) and the weight is only 49.5g, which can be said to be a very slim member of the same type of fast filling head.

As for the wire for charging, the author has always recommended braided wire. Compared with plastic material, braided thread is not afraid of deformation, aging and yellowing, and the thread body is also very tactile and recognizable. After use, the author can't go back. I usually choose Belgin's product (loyalty powder) for data cable, and I only choose Besi for charging cable. I believe that readers who are familiar with me are very clear.

Bess, intelligent series fast charging data cable, supports Apple's 20W fast charging, and also has colorful color matching options, but the author is always black and white.

I have to say that the face value of the white braided wire is really good, and I like it very much.

In addition to portable charging equipment, there will be a slightly more powerful charging head in the travel bag, which will be directly plugged into the room socket to charge the mobile phone and mobile power supply at night.

The author chooses the super silicon charger, which is also Besi's, with power of 30W and dual interface design1a1c.

The charging head adopts the new silicon-based material "Super Silicon", which has great advantages over the traditional charging head products in terms of density, thermal conductivity and efficiency conversion. The products with the same power can be smaller in size and lower in temperature. Thanks to this new technology, the charging head is small in size, and at the same time, the folding needle design is realized, and the portability is improved by one step.

In recent years, mobile phone shooting has become more and more powerful, and the author came up with the idea of replacing the camera with a mobile phone, but chose to give up for various reasons (the mobile phone is still weaker than the camera in all aspects). It was not until the launch of iPhone 13 Pro that the author went out for a day and experienced the advantages and disadvantages of this generation of mobile phones and cameras in detail before regaining this confidence.

In fact, there are still many skills and accessories to talk about the shooting of mobile phone Vlog, but the length should not be too long. I'll tell you more about it when we share the trip later.
