How to display iPad/iPhone to a computer

There are many apps to mirror iPad/iPhone screen to a computer. Here are some of them.

  1. LonelyScreen: it is a free, easy-to-use AirPlay receiver you install on your PC. 1) download and install LonelyScreen on your computer. 2) Once LonelyScreen is running and has been unblocked in your firewall, the main screen displays. The receiver name is “LonelyScreen” by default. This name will display on your iOS device as an AirPlay receiver to which you can mirror information. 3) Now, you’ll set up your iOS device to send information to your PC. To do this, LonelyScreen must be running and connected to the same Wi-Fi network as your iOS device. LonelyScreen can be minimized, but don’t exit the program. 4) When an AirPlay receiver is active and your iOS device can see it, AirPlay is available on the Control Center. Tap on it. 5) “LonelyScreen” you assigned to the LonelyScreen receiver, displays on the AirPlay screen. Tap on it to select it. 6) To start mirroring your iOS device on your PC, tap the “Mirroring” slider button that displays. 7) The Mirroring slider button turns green indicating your iOS device’s screen will be mirrored to your PC. Tap “Done”. 8) You are returned to the Control Center. Notice that the name of the LonelyScreen AirPlay receiver now displays on the Control Center. Tap the down arrow at the top to close the Control Center. 9) Now, whatever you do on your iOS device displays in the LonelyScreen AirPlay Receiver window, including music and videos. You can enlarge the LonelyScreen window to make the content from your iOS device larger on your PC’s screen.
  2. iTools Airplayer: With the latest version of iTunes installed, you can use iTools to display iPad on computer. 1) Open iTools on the computer and connect your iPad through USB cable. 2) Click “Desktop” and then tap on “Live Desktop” on the top of the screen.

Keep your iPad activated and mirror iPad screen on computer.

3. ApowerManager: is also completely compatible with iOS and Android operation system. 1) Download/install this tool and connect iPad to computer through USB cable. 2) Launch the ApowerManager. Click “Tools” tab on the top of the interface. Open “iOS Recorder”. 3) Make sure your iPad and PC are connected to the same WiFi network. On your iPad, swipe up from the bottom and tap “Screen Mirroring”. 4) Choose the name of your computer. 5) Then your iPad screen will be mirrored to the computer. Click “Start recording” to record the phone screen. Or click “Screenshot” to take a screenshot. Under “Options” > “Recording settings” > “Audio input”, you can choose to record system sound, microphone or both.

4. Reflector 2: Here is how. 1) First, you’ll need to install Reflector 2 on your PC. A seven-day free trial is available, or if you’ve already purchased, you can download here. Follow the on-screen instructions for installation. Once installed, launch the application. 2) Connect your PC and your iPad to the same network. 3) On your iPad, swipe up from the bottom of the screen to reveal the control center. 4) The AirPlay option is to the right of the AirDrop option and only appears if an AirPlay destination (Reflector 2 in this case) is available.

Tips for Shooting Backlit Portraits

Backlight photography literally means any type of photography wherein the primary light source is positioned behind the subject. Here are some tips.

  1. Set Camera Settings: Wide Aperture between f/1.8 to f/5.6, Shutter speed above 1/100 seconds, low ISO between 100 – 800.

2. Light resources: When we take backlit photography, the back ground may be over exposure while the subject is dark. You may use offline flash. However, the flash may watch out the background. It is recommended to use reflector. In the follow example, we use phone flash.

3. Position and diffuse the Sun. Find a location where the sun can be partially covered by your camera, or use subject blocking the sun
while still allowing the light to shine onto your subjects. Change your position or subject position.

4. Focus: use spot metering and single focus so that you can get the right exposure for them rather than the background.  In addition to spot metering, try using manual mode when focusing rather than automatic.

5. Filter the sunlight and flare by using umbrellas or a lens hood.

室内摄影实例

  1. 楼梯:最好有闪光灯,光圈F7.1 左右,速度1/100左右,ISO 400 以下。多拍几张,不同角度,不同构图。这个场景要拍得高大上,拍出洋派豪华。

2. 走道:如果光线好的话,可以不用闪光灯。建议使用大光圈, 比如F2.8,
速度1/100左右,ISO 800 以下,焦段可以长一点。试一试过曝。这个场景最好拍出虚化背景。

3. 壁炉:这个场景应该是比较舒适,轻松,随意,可以有很多的想象的空间。摄影的参数类同于楼梯。

我们举一个例子。

4. 窗口自然光:有几种拍照角度。

A 顺光 – 摄影师背对窗口,人面向窗口方向拍摄,示意图如下:

效果

B.逆光 – 让拍摄对象处于窗口和相机中间即可,示意图如下:

效果可以是剪影。

为了避免背景过曝,可以用反光板或者给主体加一点光。

C.侧光 – 窗口侧光是最常用的一种方法。拍摄角度为让窗光出现在主体和相机中间,偏向主体一侧的地方,示意图如下:

一般来说,在使用侧光拍摄时,我们建议主体明亮突出,背景自然压暗以达到的戏剧性效果,或者说类似经典油画的效果。要拍摄这种感觉,最重要的两点,一是通过窗帘控制窗口进光的面积不要太大,二是主体要离窗口光位置比较近。比如

D.侧逆光 – 实际上窗光相对于相机更像是侧光位,只是相对于相机镜头指向,又有一定侧逆光的感觉。

1.可以看到这回是以遮光窗帘为背景,而基于其相对窗口的角度,可知只有很少的直射光可以到达背景。

能够达到背景的基本都是光线进入到室内之后经由墙壁,天花板,地面等产生的反射光,这部分光量相对很少,所以再一次,当我们对靠近窗口的主体正确曝光时,背景又被自然压暗了;

2.我们可以大致做出主体上的光路示意图如下:

很明显,主体的“红色面”是受光最多的一部分,其面积相对主体本身较小,而“蓝色面”受到的光照相对就会快速衰减,呈现自然渐暗的效果。

所以采用这样的方法拍摄时,往往就可以自然得到类似轮廓光“勾边”的戏剧性效果,我们需要调整主体人物的动作以配合这种光线,就可以得到理想效果。

3.使用这种方法拍摄时要注意一点:因为会有部分窗光“指向相机”,所以容易产生炫光,实际使用中要注意规避。
