How to adjust the aperture of the iPhone camera

Even b-gate**.

1. The shutter speed is a digital camera.

The shutter speed of different models of digital cameras is completely different, so when using a certain model of digital camera to shoot a scene, you must first understand the shutter speed, because when pressing the shutter, only consider the shutter start time, and grasp the shutter release time, in order to capture a vivid picture.

2. Usually, the shutter speed of ordinary digital cameras is mostly within 1 1000 seconds, which can basically cope with most daily shooting. The shutter is not only "fast" but also "slow", that is, the delay of the shutter, for example, some digital cameras have a shutter of up to 16 seconds, which is enough to shoot night scenes, but the shutter is too long and will also increase the "noise" of the digital **, that is, there will be miscellaneous streaks in the **. In addition, mainstream digital cameras must have an aperture priority mode and a shutter priority mode in addition to an automatic shooting mode.

3. Aperture priority mode is to decide the size of the aperture by the user, and then the camera calculates how much light enters according to the ambient light and ** settings, etc., which is more suitable for still objects. In the shutter priority mode, the user decides the shutter speed, and then the digital camera calculates the appropriate aperture size according to the environment. Therefore, the shutter priority mode is more suitable for shooting moving objects, especially digital cameras are very sensitive to vibration, and even a slight shake of the camera will produce blurry ** in the process of using telephoto.

This is even more pronounced at a distance. When shopping for a digital camera, you'd better choose a model with these modes to ensure the effectiveness of your shooting.

Hello, it can be adjusted by the slow shutter software. The app allows users to choose automatic, manual, or light smearing effects depending on how they shoot, and by selecting the mode, they can choose the appropriate shutter speed, or even bulb, according to the market.

The so-called "little dot" of the iPhone is actually a function of the iPhone system, called "AssistiveTouch", which can help us greatly reduce the frequency of use of the volume buttons on both sides of the home and health, so as to prolong the life of the body. But many people don't know how to set it up, and even some "whites" who have just bought the iPhone don't know that there is such a function. Let's teach you how to use it.

1.First of all, find the "Settings" icon on the main interface of your iPhone and click on it.

2.Then we find the "General" option, click in.

3.Then find the "Accessibility" option and click on it.

4.Then, scroll down and near the bottom there's an "assistivetouch" option and click in.

5.Just leave "AssistiveTouch" on and you're done!

6.In this way, whether it is locking the screen, adjusting the volume, or taking screenshots to close the background, all kinds of functions that require the use of buttons can be achieved through small dots!

Tips for using iPhone!

1. Adjust the default settings.

1. Background app refresh.

Our mobile phones are equipped with various apps, whether they are opened or not, they are constantly refreshed in the background, can they not consume power? It is recommended to close it with one click. And even if the background app refresh is turned off, WeChat, QQ will still be notified when there is a message.

Settings - General - Background app refresh.

2. Turn off location services.

Settings – Privacy – Location Services.

3. Turn off data analysis.

Data analysis? I've been using an iPhone for 7 years and still don't know what it does! After checking it, I found that this function not only consumes power, but also involves our information privacy, and our usage habits and user information may be obtained, so it is recommended to turn it off.

Settings - Privacy - Analytics - Turn off shared iPhone analytics.

4. Turn on Limit Ad Tracking.

Browsers, games often pop up ads, but also a big drain of power**! But iPhones can restrict ads, did you know? If you have been troubled by ads, you can turn on this feature and not receive ads! Remember to turn it on

Settings - Privacy - Ads - Check Limit ad tracking.

2. Selectively adjust the settings.

1. Turn off the relay function.

If you have two or more Apple devices and log in to the same ID, this feature is very useful, such as copying on one end and pasting directly on that end. But if you don't have 2 Apple products with the same ID, you don't need to turn on this function.

Settings – Universal – Turn off the relay.

2. Turn off Siri

Siri is a very useful feature, but many people rarely use it. If you don't use Siri often, you can choose to turn it off, because it actually consumes a lot of power.

That's all for today's sharing, if it helps you.

Taking the iphone8 mobile phone as an example, there are the following steps to adjust the "focal length" of the camera:

1. Open "Camera" on the desktop of your phone, as shown in the following figure.

2. After turning on "Camera", place both phones in the middle of the screen and slide them to the "diagonal" in any direction of the screen, as shown in the figure below.

3. Finally, drag the "cursor" below to adjust the "focal length" of the camera, as shown in the figure below.

Summary. Hello, the large aperture mode of the Apple phone refers to the function of using a relatively large aperture (which is more common in low-light environments) when taking photos to improve the depth of field effect. To bring up the wide aperture mode, you can follow these steps:

1.Open the Camera app and select the ** tab. 2.

Find the "Aperture" icon at the bottom and click to enter. 3.Drag the slider from to to bring up the wide aperture mode.

It should be noted that in wide aperture mode, the depth of field effect of the lens will be improved, and the foreground and background will be very blurry, so it is suitable for shooting some art**, not for shooting everyday life**. The above is mine, I wish you a happy life!

I'm still a little confused, can you be more detailed?

1. Enter the desktop of the phone, find the "Settings" icon with a gray gear, and then click to enter the interface of setting the sail grip.

2. When we enter the settings interface, swipe the phone screen, find the "General" option and click to enter.

3. In the general, you can see a selection of "auxiliary skin holding function", click directly to enter. In the accessibility screen, tap directly to open the StiveTouch settings.

4. If the screen does not display a small aperture, then the assistive touch is presented in the off state, so at this time, you need to turn on the assistivetouch selection and present the green open state.

It can be adjusted. Tap the "f" button to change the effective aperture when shooting in Apple, measuring in f stops. The lower the number, the wider the effective aperture and the shallower the depth of field.

A shallow depth of field means that more of the background will be out of focus when locked on the subject, so increase the number of f-stops for areas where you want all frames to be in focus, such as landscapes. For an eye-catching "cinematic" look, lower the f-stop.

Here's how to shoot with a wide aperture**: first turn on your phone's normal photo mode; Then, press and hold the object or person you want to shoot in the point until "Auto** AF Lock" appears, and click the shooting button to shoot successfully**. However, there are still flaws with a large aperture, and it is generally within 7-20 cm in front of the lens to have an effect.

Cancel the Apple aperture to open the Apple phone settings, accessibility, touch, assistive touch, and turn off the assistive touch button. Aperture is a device used to control the amount of light passing through the lens and entering the photosensitive surface of the fuselage, it is usually in the lens, and the aperture size is expressed by the f value.

Introduction to the aperture

For a lens that has already been made, we can't change the diameter of the lens at will, but we can add polygons inside the lens.

or a circlar, variable area perforated grating to control the amount of light transmitted through the lens.

This device is called Aperture Hunger, and the size of the aperture is expressed by the number f, which is denoted as f.

The aperture of some simple cameras has the function of shutter, most of these shutter aperture are double-bladed cat's eye apertures, which are different from simple cat's eye aperture in that the shutter aperture is usually completely closed, and at the moment of pressing the shutter, the double-blade aperture opens to a predetermined aperture, and then closes immediately after maintaining this aperture to a predetermined shutter opening time, so that the aperture has the function of shutter.

The function of the aperture is to determine the amount of light entering the lens, the smaller the value behind f, the larger the aperture and the more light intake, and vice versa, the smaller it is. Simply put, at shutter speed.

**Under the condition that the speed remains the same, the smaller the aperture f, the larger the aperture, the more light intake, and the brighter the picture, the larger the aperture f, the worse the light envy digging circle, the smaller the beam, and the darker the picture.

You're talking about the white halo on the screen, right? If it's filial piety, it's very simple:

In Settings, General, Accessibility.

Turn on the assistivetouch.

And it came out. If you say Assistive Touch, it is in the settings and then through the early use of the auxiliary function, pull to the Assistive Touch below to open it.

1.Adjust to A mode (aperture priority), then turn that wheel (dial wheel or dial), you can adjust it, and then go to M mode Kai Rubber type, and the aperture "value" remains unchanged.

2.Directly in M mode, press the "aperture button" at the same time (it seems to be the key to adjust the EV, anyway, as long as there is a button above, there is a "circle" diagram on the non-button) and turn the dial, the effect is the same.
