Why Restrict USB Drives from accessing your computer?

We use USB Drives everyday and are grateful for the service they provide, but on the downside, there are three reasons people should restrict or control USB Drive Access into their computers. They are ---- Virus Traffic: There are many people these days that use USB Drives on a daily basis.  At work or at home you’ll find many people carrying their USB Drives with many good and bad files.  The most draw back to using USB Drives is Virus Traffic.  A USB Drive will carry viruses to all accessed computers.

Personal Privacy: Today, even the little brothers and sisters carry USB Drives in their little pockets.  If you’re at home and you keep personal notes, pictures, videos, or even working on an important project; you need to have your computer secured. Otherwise with one little innocent mistake all your data will be gone after your little sibling inserts a USB Drive into your PC.  Your private information might be uploaded on the internet as a silly joke. You can use the USB Drive Monitor to secure your PC from Foreign USB Drives or even lock and unlock your PC by using your configured Personal USB Drive.  You can activate a screensaver or generate a sound or custom text alert to intruders.  You’ll have full control over your PC.

Data Theft: It’s a good practice to use USB Drives at work, but with rules and regulations.  Without proper USB Access Control you’ll have your company data and privacy at risk. Solution One: You can have a master PC that logs USB Drive files by using USB Drive Monitor to identify unique hardware key and user name as well as log USB Drive file content and use this PC as a checking gateway for your company. Solution Two: You can assign a USB Drive to be officially used inside the company only and restrict all other USB Mass Storage Devices.  You can configure this USB Drive by using the USB Drive Monitor and securing the program with a password used by the administrator.   The USB Drive monitor can be configured to delete files on unauthorized USB Drives inserted into any computer to make sure no data is lost.

Solution Three: It’s the important information that needs to be protected.  Your company can assign specified PCs to have confidential and important data and secure then with the USB Drive Monitor.  You can have all USB Mass Storage Devices disabled, Sound and Text messages enabled, Task Manager disabled, Screensaver enabled and file deletion on Foreign USB Drives inserted will still be an option.

Helpful Steps to Choose A Great Lightweight Portable Tripod

The tripod is an absolute must because after hiking into an area you become winded and tired and are much less likely to hold your camera still. Also, if you are using a telephoto lens, setting up a panoramic shot or using long shutter speeds you will need a tripod to eliminate shake and create sharper photos. You'll want a tripod that is lightweight, compact but still has the features you need. No one tripod will meet all your requirements, so you must determine the elements most important to you and chose the ones which meet your main needs. When you are purchasing a tripod you want to pay attention to these five aspects.

Weight The lighter tripod is, the easier to carry around. There are trade-offs, of course. The lighter tripod is not as stable particularly when raised to its maximum height. There are materials on the market now such as carbon fiber, which help cut the weight of larger tripods. The down side of these tripods is the price. They are quite a bit more expensive than those made of aluminum.

Height Height is crucial, because standing hunched over your camera all day will really put a crimp in you enjoyment. Also, you want to think about the portability of the tripod. The smaller it compacts down, the more portable it is.

Stability Stability is very important because this is basically the point of using a tripod. Some tripods come with a hook in the bottom of the center post so you can hang a weight on it to keep it steady, particularly if it is windy. Camera shake, even just a little will decrease the quality of your photographs. A tripod is just about mandatory if you are going to take long exposures, use a telephoto lens or take panoramic shots.

Durability When you use your tripod for out door photography and/or nature photography, you want to make sure it will stand up to the elements. A tripod should be able to withstand hard use over a long period of time without breaking. It makes no sense to invest in a product if it is just going to break in a few weeks or lock up because it got wet.

Ease of adjustment Last but not least you don't want to fumble around with ungainly controls. You want a tripod that will adjust rapidly and easily so you avoid missing important shots. Flick lock legs that adjust individually are great. A ball-head and a quick lift enter post makes for fast adjustments once you get the tripod set to the right height.

Taking all the aspects above into consideration, I think you can choose a tripod to fully meet your need.

How Will the Wireless Keyboards with Trackball Benefit Our Health?

Keyboards and mice are two of the most important devices for PC computers. The people who engaged in the Research and Development are so creative to combine them together.

Roller sensors detect the rotation of direction with the ball and they handle the direction on the cursor. For those who are wondering, just imagine an inverted ball mouse. That is exactly the same format to build trackball keyboards.

With newer technologies, many of the wireless keyboards with trackballs use optical sensor technologies. Instead of making use of roller sensors to detect the direction, optical light is applied to track the direction with the rotation, improving accuracy and manage.

Wireless Trackball Keyboard is excellent for users who use the mouse typically, for example programmers and typists. Extra than usually, we use the mouse incorrectly.

How to Photograph Firewoks Displays

Below are some useful tips to help you get started.

Planning Planning is the most important when photograhing Fireworks Displays and this is what most people tend to ignore. Always get to the location early. Be sure of where the fireworks are being setup and what part of the sky will it be lighting up. Try asking the organisors if possible of what they are planning. Look around the location and take note of the lightings and surroundings. You might want to decide now on what lenses and the focal lengths to use. Remember the first and most important thing in fireworks photography is planning and anticipation.

Shutter Speed

It is not necessary to set your shutter speed to a very low setting. The temptation to keep your shutter open too long is because its dark and you need to do that. The problem is that fireworks itself are bright and you might over expose them and you may end up not having a clean and nice shot. What you may get is too much of the smoke in you photograph.

Aperture What aperture to use in Photographing Fireworks Dispalys? Many people thinks that they need to open up the aperture in order to capture them right. But remember, the lights that fireworks emit is quite bright. So we can set our aperture between mid to smaller f stop. And again it will also depends on what shutter speed you have selected.

Framing and Focusing

Where to aim your camera? This is one of the most difficult part in photographing fireworks displays. You normally need to aim your camera before the fireworks goes off. Actually it is better to look in the sky rather then looking at my view finder so that we can see what’s happening around us and also anticipate the moment or the right time to shot. Always manually focus your camera or put it on infinity. It’s quite impossible to use auto focus mode in low light and you may end up missing a lot of shots. So set your focusing in advanced and fix your focal lengths but remember to adjust your focusing if you happen to change your focal lengths.

Capturing the Mood and Surroundings When photographing Fireworks Displays many people tend to just capture the Fireworks and forgetting the foreground or the background. Remember Fireworks Displays are often relates to celebrations and occasions and I personally feels your picture must relates to the occasions and it must tell you where, what and when. Don’t forget to include other elements such as people, landmarks or other perspectives to make your photograph more meaningful and the Fireworks Display looking more spectacular.

Flash Photography Techniques – Ambient Light Plus Flash With careful use of flash, you can make your photo looks natural as though no flash had been used, instate it will enhance the photo further reducing contrast and yet looking very natural.

Take as Many Shots as Possible and Track Results Keep taking as many shots as possible and do a quick check occasionally. But remember….. don’t check after every shot or you may end up missing the action!!! You might not have enough time. If you are using Digital Camera take advantage of it and keep on taking.

How to Take Better Portrait Photos

Portrait photos are very impressive. Taking high quality portrait photos is an art that takes time to master. So let’s follow some guidelines that can help us achieve high quality portrait photos in a short time and without being a professional photographer.

Choose the right background: A portrait photo is all about the object's face. The most important part of the photo is the face. Choosing the right background can make sure the viewer is focused on the face. Pick a neutral background that does not attract attention.

Blur the background: In addition to choosing a neutral background you should further blur it. This will put even more emphasis on the object instead of its surroundings. Blurring the background is best achieved by taking a photo using a shallow depth of field. This can be accomplished by using a zoom lens and shooting from a short distance or with a wide aperture manual setting. If your camera does not allow you to do so, you can always blur the background later using photo processing software on your computer.

Use natural lighting: Natural lighting is necessary in order to capture the full color range and warmth of the skin. It is best to take portrait photos outdoors during the day. When shooting outdoors position the object in a way that the sun light hits it from the side. Never take a photo with the sun behind the object - results in shading - or right in front of the object - results in over exposing the face and distorting its natural colors. If some shades appear on the face use a soft fill-in flash to get rid of them. If you have to shoot indoors and use artificial lighting always use indirect light sources such as bounce flash or lights that illuminate the room instead of directly shining on the object.

Take many photos and experiment: In the digital era the cost of taking another photo is zero. One of the best ways to shoot a great photo is simply by shooting many photos. In fact all professional photographers do that they keep on shooting more and more photos to practice. Experiment with different settings - lighting, object position, white balancing settings to get different color temperatures, exposures, depth of field and more. We should keep in mind that Practice makes perfect.

In conclusion if you have a good camera and the willingness to experiment portrait photo shooting you will quickly achieve the skills needed in order to shoot great portraits and impress your friends with portraits photos that look impressive and professional.

What to Do If You Lose the Important Data

Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as internal or external hard disk drives, solid-state drives (SSD), USB flash drive, storage tapes, CDs, DVDs, RAID, and other electronics.Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.

If you have lost your computer data and don't have any backup of that lost data; then, in this condition, of course you can get back your lost data by using a third-party data recovery software tool to recover your lost data. But it can be difficult; you will find that most of them are chargeable, they can be only used in a short time, and you are not sure if it will work,either; OK. Then you may think that you can ask some companies engaged in this to help you. But have you thought about this----how about your privacy? Safety threat management also may be permitted using the computer forensic tools. The companies obtained by the pc forensics are the event of the plans to gather the digital evidence. Laptop forensic can be used for its services to help legal cases and civil warrants.

Are there any other devices to help you to solve this problem? Do not worry, today we have a device which can be used to do USB data recovery,it is a kind of USB key used to protect the computer data, avoid system down and data destroy. it can not only used to recover your losing data, it can also help to protect the computer data, avoid system down and data destroy.

Basic Skills in Photo Taking 1: The Application of Three Flash Modes

You can find out the maximum range of the flash from the catalog or the specifications in the user manual. Look for "Effective Flash Range" under the Flash section for the maximum effective distance (measured from the tip of lens) where you can still get an appropriate brightness (correct exposure) using the flash. When shooting night scenes or indoors, any subject at a closer distance will appear too bright (overexposed) and at a farther distance will appear too dark (underexposed).

Usually, there are three flash modes for common digital camera. You can change the flash mode depending on the shooting conditions.

In [AUTO] mode, the person in the fore will appear correctly exposed but, since the light of the flash cannot get to the background, it will appear too dark. Using [Flash Synchro], a slow shutter speed is used so the background appears bright enough and the person in the fore appears correctly exposed thanks to the flash.

[Flash Exposure Compensation] is a function that allows you to correct the amount of flash set automatically by the camera just as you would adjust the exposure with Exposure Compensation. You can compensate the amount of flash from -2.0 to 2.0 stops in 0.3-stop increments. The following scene seems best to me at +0.3 stops but, just as with exposure compensation, personal preferences will vary.

But some people will always blink at the moment when the flash flashes. At this time, the LED video lights may be more useful. They can offer much natural light in photo taking.

A List of Sites Where You Can Store the Data

In modern times, there is a new method that we can store our data online. Storing files online is the easiest as well as the most convenient method. Access from anywhere to the files stored online is achieved by remote online data backup. In addition to immediate access, this facilitates easy and quick retrieval of files that are lost from the main server. All the documents are stored on an exclusive server that is adequately protected from virus and malfunctioning of the hardware, etc... Majority of companies suffer due to loss of data that happens within few months or a couple of years. Hence, to find out solution for their safe storage is all the more important.

The main advantage of online storage of documents is remote access. Those who have connection to that particular server can access the data from anywhere. Moreover, the set up for access to the stored data from the PC or laptop is protected by a confidential password. Thus, safety of the stored data is 100% ensured giving no chance for misuse.

Here are some sites where you can store the data: http://www.divshare.com http://www.box.net http://rapidshare.de http://www.axifile.com

On another hand, if you don’t always have network available, there are also many other devices can be used to store data today: the portable disks, hard disks, flash disks, memory cards, etc.

Usually the price differs depending on how much capacity the device possesses. Devices come in different shapes and sizes and the main goal of providers is to make devices that are small in size and have a lot of free space on it.

Storage devices are not so expensive nowadays as people are constantly using them for fast file moving, copying and similar processes. If you need a storage device you should first see what you need, is it for your personal computer or for transport of data. Once you decide what you need you have a really big choice of designs and technical specifications of devices so you can choose what suits you best, you can than compare the prices and make the best deal possible for yourself.

You must be careful when using storage devices because you can get a virus from some other computer easily and you can infect other computer as well. That particular virus can be attached to some executable file on your storage device. Let’s take the USB storage device for example. You can plug in the USB device and the virus will automatically start to look for other files that are executables on that computer.

The Correct Ways to Clean the Lens

Cameras are one of the necessities our life today. And the lens is the most important part of the camera. So to keep the lens clean is really important. But even something as simple as wiping a lens can be done in the wrong ways, with disastrous results. So, here I am going to talk about the correct way to clean the lens yourself. Lenses in general have several coatings designed to let more light in by canceling reflection. Most are integral to the glass; some may be applied on top. The coatings are tough but not indestructible, and they are especially susceptible to scratches. The problem is: wiping a lens can make the grit you are removing act like sandpaper. Here’s the right way.

1) Take the air. Start by blowing as much dust away as you can with air, but not just any air. For example, the high pressure air is not a good choice, because it will blast the lens and break the element. Air from compressors can be laced with small bits of oil that is hard to get off a lens. Canned air uses refrigerants, which can shoot a gust of damaging freezing air.

2) Brush up. Another option is to use a lens brush to sweep dust from a lens, but be careful in handling the brush, because the oils from your hands get on the bristles while oils can be especially hard to remove from the lens. So, brush as one that is often used, but it is much more expensive than an air bulb.

3) Friendly fibers. In most cases all you need is a good lens cloth. They are usually made of microfiber. One wipe will last a long time, but you have to take care of it. And make sure you wash your microfiber cloth from time to time. Just throw it in the washing machine. And the old standby, disposable lens wipes, is still available and acceptable, but never, ever use paper products, because they are very, very rough and will easily scratch the surface of the lens. And remember that when you do this, always start in the middle of the lens and wipe in concentric circles, pushing any gunk to the outside of the lens, where a tiny bit of residue can be swiped up. Finally, if you are really tired up of cleaning the lens yourself. You can just simply have a protector for your lens, which will save you a lot of work while providing good protection.

It is time for you to learn more about the computer knowledge.

When we talking about the desktop model of computer, it means the computer itself not keyboard, mouse, monitor. Technically speaking the box which contains the computer is called system unit. Before the computer is used for performing any operation a set of instructions are given to it. The set of instructions are called program. A set of programs called software. A special type of software is operating system reside in the hard disk of computer. It runs firstly when we start the computer.

For the first time it can be fun to use computer but it becomes our need as we come to know about the computer features. Computers were designed to make life easier not be too complex. In the past, technology was based on the all-in-one concept to make computers, but now computers are usually come in parts, divided into hardware and software components. Hardware makes up the physical elements of the computer, such as the hard drive, whereas software provides the operating system and the programs that allow you to create computer files.

Computers have made a global impact and have changed the way we work, communicate, or search for information. Talking of business, now there is no need to worry about storing and maintaining paper files. Computers have revolutionized the way businesses function. A very recognizable term Technology encompassing many aspects of computing helps to produce, manipulate, store and/or disseminate information. Computers can be seen in almost all spheres- home, business, schools, hospitals, accounting, buying, selling - the list is endless.

Computer is a machine which computes data. It performs high speed mathematical or logical operations. It also manipulates data according to a set of instructions. It has the ability to store and execute programs, which makes it differ from calculator. Each and every computer must have a main memory, control unit, arithmetic logic unit. Complex computers include programs for some necessary duration. Charles Babbage is the father of modern computers. A computer can read one instruction at one time, it performs the operation based on that instruction, than it reads next instruction. The instruction given to any type of computer can be single, multiple, or simple. It can also used for simple or complex operations.

What Are the Usages of Camera Shutter Releases?

As all kinds of cameras are popular today, a shutter release has also become a must for many people. But not everyone knows what it is, not to mention how to use it. So today I will provide you some ideas about the camera shuttle release and also some tips for how to use it correctly.

First of all, let’s make clear what camera shutter release is. Serious. It can be a remote or cable based control for your camera shutter. It's main advantage is allowing you to take shots without interfering with the camera stability, but it could also be used for shooting from awkward/distant positions or when taking shots including yourself. Another common use of them is to do aerial photography (using R/C planes and helicopters, kites etc), where the shutter can be controlled by radio or electrical signals through a wire.

A third option, but not exactly remote, is to use automatic shutter control mechanisms based on time (those are usually available in the camera itself) or events. Using special software (for example CHDK for Canon cameras) or tethering you could make the shutter trigger whenever there is movement in the scene, a change of light or some other event.

Now that we have made clear what camera shuttle release is, let’s see how to use it. Since most of the shuttle releases are the wireless one. So, first of all, you normally have to set the camera to accept the remote signal. This can be found sometimes with the drive modes or self-timer, it really depends on your model. Then, once the camera is ready, aim at one of the IR receptors and click the release. Some cameras work with a front receptor, while some with a back one and some have both. Look for what looks like a small very dark window.

In a addition, the camera can be in any modes and it will take the shot accordingly. Most models will not autofocus when used with the shuttle remote, some will let you specify this as an custom setting. Bulb mode either works by holding the release the whole time (which IMO is silly) or by clicking at the beginning and end of the internal. A few DSLRs allow both and the behavior is chosen via a custom setting.

So, after reading this article, you must get to know much more about the camera shutter release, right?
