Tip 1: How to turn on the front camera
Frontal cameras are equipped with mobiletelephones with video communication function. Also, such a camera can be used to shoot a self-portrait. In some modes, it turns on automatically, in others it needs to be turned on manually.
Instructions
1
To make a video call, first connectsuch service with the operator (if available). Then dial the number of the interlocutor (his device must also support this service, and it must be connected). But do not press the call transfer button. Instead, press the left soft key, which at this point will be named "Options". Select an item in the menu called "Video call" or similar (it depends on the phone model). When talking, direct the frontal Camera on itself - it will turn on automatically. If the interlocutor does the same, you will see it on the screen. Since it is useless to bring the phone in the video call mode to the ear (you will not be able to use either the screen or the camera), you will have to turn on the speakerphone or attach the headset.
2
If you want to reduce the cost of video calling,put the Skype program on the phone (if it is available for your model of the device, but not installed on it in advance). Correctly set up an access point (APN): its name should start with the word internet, but by no means wap. Register on the Skype website and get your login and password. After launching the program, enter them. Add nicks of contacts to the contact list. Choose one of them and call him. The front camera will turn on automatically, as in the previous case.

To make a front-facing camera a self-portrait,First, launch the Camera application on your phone. In some devices, you need to hold the shutter button for a long time, in others it is easy to press (with the unlocked keyboard), in the third - to find the corresponding item in the menu (for example, "Applications" - "Camera"). Immediately afterwards, a picture will be displayed on the screen, which is captured by the main (back) camera of the phone. To turn on the front one, press the left soft key, and then select "Second Camera" in the menu (it can also be called a different one). Point the camera at the desired angle and from the desired distance, then take a picture by pressing the shutter release button (in some phones, do not press it lightly but press it all the way down, and sometimes hold it down for about a second). After making a self-portrait, do not forget to switch the mode back, by selecting the menu item "Main camera" in the menu.
Tip 2: How to turn on the built-in camera
In all modern laptops are presentwebcams. Usually this device is built into the top cover of the laptop, and the peephole of the web camera looks at the user from the panel directly above the screen. By default, the webcam is turned on and can be used at any time. If you have a need to include a web-Camera, it can be done in several ways.
You will need
- - a computer;
- - driver.
Instructions
1
Check if the webcam is onDevice Manager. Start Device Manager by right-clicking on the My Computer icon and selecting Properties. In the list of devices, look for image processing devices. If such a device is present, you can use it through the "Devices and printers" section.
2
Open the Device and Printers window. You can find it in the "Start" menu, under "Control Panel". Right-click on the camera icon and select "Get Image" (get pictures). You can also take a photo via Skype.
3
If the webcam is not present in the "Managerdevices ", or is present, but with an exclamation point, it means that the device does not have suitable drivers installed. Take the drive with drivers and utilities from your laptop and install the correct driver. Also, automatic updating of Windows can help in this matter.
4
Check if the webcam is detected in the BIOSmotherboard. When you turn on the laptop, press F2 (maybe Del, Esc or another button depending on the model). Examine all the BIOS items and find one that matches the Internal Camera or Onboard Camera. Set the parameter to Enable. Download the operating system and install the drivers for the webcam.
5
In some laptops,Camera can be disabled directly on the case usingspecial button. Make sure that there is no such button or it is in the ON position. If all these points are met, and the device still does not work, contact the service center. If you still have a warranty on your computer, you can easily carry it to a service center and you will be free to solve this problem. In general, it can be said that to include the built-in Camera on a computer is quite simple.
Tip 3: How to turn on remotely the camera
To observe what is happening ina certain place, it is necessary that there was installed a camera connected to the Internet and a personal computer from which you could control it. By connecting to it, you will see everything happening in real time.
You will need
- network switch.
Instructions
1
Create a connection over the local network toconnect to a remote camera. To do this, you will need a special network switch. It is needed in order to create several connections at once. Take two cables with Ethernet connectors and connect all devices.
2
Use the installation program. As a rule, it is included in the basic package. If not, download it from the Internet and install it on your personal computer. Use this program to determine the IP address of the remote camera. In consequence, you will enter it into the address bar of your browser or any other program convenient for you.
3
Create a static IP address so that you can remotely connect it remotely Camera. Open your browser. In the address bar, enter the IP address of the camera. Use modern browsers that support video streams so that you do not need to use additional software.
4
Use special programs if you want to connect to a camera that is far away from you. To use a remote Camera install on your personal computer WebCamMonitor 4.20 or WebCam Survevor 1.7.0. Using this program, specify the IP address of the camera you are interested in. Then a fairly simple setup procedure follows. You will only need to answer questions that the program will ask.
5
If the installed program is not Russified,download the crack, or use an interpreter to properly rebuild the software. After that you will be able to use a remote webcam, if this usage is legitimate and the administrator of the computer to which this camera is connected will grant you the appropriate rights.
Tip 4: How to build a frontal perspective
When creating an architectural project orthe development of interior design is very important to imagine how the object will look in space. You can use the axonometric projection, but it is good for small objects or details. The advantage of the frontal perspective is that it gives an idea not only of the appearance of the object, but also allows visual representation of the ratio of dimensions as a function of distance.
You will need
- - paper;
- - a pencil;
- - ruler.
Instructions
1
Principles of building a frontal perspectiveare the same for a sheet of Whatman and a graphic editor. Therefore, execute it on the sheet. If the subject is small, the A4 format will suffice. For a frontal perspective of a building or interior, take a larger sheet. Lay it horizontally.
2
For a technical drawing or drawing, selectscale. For the standard, take any clearly distinguishable parameter - for example, the length of the building or the width of the room. Put on the sheet an arbitrary segment corresponding to this line, and calculate the ratio.
3
4
Define the second parameter of the picture plane. This can be, for example, the height of the room. If you are going to build a frontal perspective building, capturing a piece of the surrounding space,the height of the picture plane can be arbitrary. From points A and B, draw up perpendiculars to the height of the picture plane and connect their ends with a straight line.
5
Select the position of the horizon line. It should be slightly above the middle of the picture plane. When constructing the frontal perspective of the interior of a normal room in a modern house, for example, the horizon line should be about 1.5-2 m high. If the ceilings are high, then the horizon line can also be higher.
6
7
From the line SP to the points S, plot 2 angles of 45º andContinue the rays until they intersect with the horizon line. Put the points C and D. They are called distance points. Knowing their location and the point of descent, you can build a grid of frontal perspective.
8
9
To determine the position of the transverse grid linesConnect one of the outlying points to the points on the base of the picture plane, which you indicated by numbers. Connect the second separation point to the diagonally disposed end of the base. The points of intersection of this line with the segments D1, D2, etc. will give you the opportunity to determine the ratio of sizes as they are removed from the observer.
