Terms for digital cameras
This is a list of some of the main terms for using a digital camera
- Pixels: Are used in digital imaging and represent the smallest piece of information in an image. Pixels are tiny and one dot on an image is made up of many pixels. Each pixel can be represented by a different colour and can have three or four component colours.
- Megapixels: Is a measurement of digital photo quality and one megapixel contains one million pixels. A 1600×1200 pixel image size is a common size and is said to have “1.9 megapixels” (1600×1200 = 1,920,000)
- A 5 Megapixel digital camera: A camera capable of shooting an image measuring five million pixels in size.
- Pixel Count: The amount of pixels that an image contains is called the pixel count. The clarity and sharpness of an image will look better with more pixels.
- PPI: Or pixels per inch”, is a term used to describe an element in picture quality. It is a measure of the amount of pixels to be printed within a specific area. If the number of pixels per inch that is displayed is higher the better the image will be to the human eye.
- Aperture: In optical terms an aperture is an opening or hole through which light is admitted. This opening behind the lens permits light to travel to the digital camera’s interior where the sensor is located.
- Digital Camera Memory: Digital images or photographs are stored in a location called memory. This is an electronic storage space built into your digital cameras for the purpose of storing pictures usually in the form of Secure Digital Cards, Compact Flash Cards, SmartMedia Cards, XD Cards. In general the sizes of a digital camera memory are 64 MB, 128 MB, 256 MB, 512 MB, and 1 GIG.
- Digital zoom: Is obtained by focusing in on a portion of an image and enlarging it with a decrease in a cameras apparent angle of view. Although it results in a loss of picture quality it is a way the digital camera can zoom in using electronics and no physical adjustment.
- Optical Zoom: As opposed to digital zoom, is the ability of a lens to change its focal length and magnify an image physically using an assembly of lens elements. It does not alter the quality of the recorded digital image and is a better option than digital zoom.
- JPEG: The perfect file format used for compact storage of groups of pixels in a photograph. To reduce the picture size this ratio was fixed by the Joint Photo Experts Group. The degree of compression can be adjusted however, the higher you compression your image will result in a larger loss of picture quality.
- TIFF: Is another file format for storing images. “Tagged Image File Format” is the longer version. While there is no loss of information in this format, the resulting file sizes are also very large.
- Digital Camera Sensor: Converts light into a digital electrical signal which then produces your image for printing or viewing. It performs the role of “re-useable negative” within a digital camera.
- Shutter Speed: The common term for exposure time is the duration which the camera’s aperture is opened allowing into your camera. Longer shutter speeds leave the aperture open longer, letting more light in and resulting in more exposure.
- White Balance: To correct all the colours in an image white balance is used to account for the intensity of light an image was taken in. Because not all light is the same intensity. However modern digital cameras usually have preset values you can
- Switch on to compensate for the different light intensities which then calculate all other colours based upon this setting.
- RAW/NEF: Is the uncompressed image as shot by a digital camera before processing. Raw/NEF image files are sometimes called digital negatives Canon introduced the RAW picture format, while Nikon calls this format NEF.
Tips For Getting Rid Of Spyware From Your Computer
Anyone who has been online for awhile now probably knows what a pop up is. Some of these pop ups come from the websites you are visiting and some of them come from spyware that has infected your computer. Of course there are some very good tools you can use to keep these popups blocked. For this article we will be taking a look at stopping spyware and how to find a good spyware popup blocker.
Spyware Blocker
The first thing you should do is install a good spyware blocker. If there is any popups that are happening because of spyware on your computer this will solve the problem. It is a good idea to install a couple spyware removal programs. If one blocker misses some of the spyware the other may pick up the rest. Many people use the internet on a daily bases, witch means most people should scan daily.
Popup Blockers
There are lots and lots of popup blockers on the market. Many blockers can be had for free and others will cost you some money for extra features. The ones that cost a few dollars usually come with the most features. For some those extra features may be worth the extra money spent. However, whether you choose to purchase one or go with a free one is up to you.
The first blocker you should try is the Google toolbar. This is one of the best free popup blockers you can get. Not everyone will want this toolbar installed on their computer and it does have a limited amount of features. But, it is good for somone looking for a simple blocker.
One of my personal favourite blockers is the Firefox browser witch is free. Firefox is very good at detecting popups and blocking them compared to many other browsers. Most people will also find that Firefox does not pickup the same amounts of spyware that Internet explorer does. One of teh best things you can to help reduce the amount of spyware on your computer is to switch to the Firefox browser.
StopZilla is one of the best products on the market for blocking popups and spyware. It can detect spyware, quarantine it, and deal with adware all in real time. This will give your computer another level of security that most computer users don’t have. I highly recommend for keeping your computer safe.
What Is The Best Way To Delete Your Data
If only people understood how hard it can be to totally delete data from a hard drive they would really be a lot more careful, especially in these days of identity theft and identity fraud. Data recovery companies are well skilled at restoring data, but then so are the computer criminal specialists, and if all you have done is a simple reformat or deletion then your personal data can be much more exposed than you would like to believe.
So what lengths do we need to go to in order to ensure that our data is securely removed?
The answer, in short, is that there is no easy method of permanently removing data from a storage media. This does not make it impossible, but does mean that you will normally have to obtain expensive software to help in the task.
Data can only be considered completely erased when it has been overwritten several times, each time using a different method. The level of overwriting usually considered to guarantee that data has been successfully erased is a seven pass overwriting method using software or manual processes that adhere to the DoD 5220.22-M standard for data erasure.
There are many companies that can provide such data elimination services, and there are also a number of software applications that can serve the process including Evidence Eliminator, M-Sweep Pro Data Eliminatior and R-Wipe software from the company behind R-Studio Data Recovery Software.
There are also more permanent methods of data destruction, few data recovery companies can retrieve data from a hard drive where the disk’s platters have been physically destroyed.
While it would not be recommended DIY data destruction is an option you could try but this would mean that you would need to totally dismantle the drive, remove the platters and physically damaging as much of the disk as possible including destroying (shattering ) the disk as well.
Always remember deleting a file does not remove your data beyond the point of recovery. Formatting a hard disk, even full formats/low level formats do not guarantee complete data erasure. Re-installing an operating system does not get rid of your data either. The only reliable method is the multi-pass method.
Not all data will needs to be totally destroyed using the above methods and if you are happy that none of your data is personal or sensitive (both business or personal) then simply dispose of it in an enviromentally responsibly way, but if you are at all unsure don’t take the risk.
Your local data recovery company will be able to advise you on safe hard drive data disposal methods and will probably have a local service. raid data recovery and data disposal should always be left to professional operators who are happy to certify their work.

How Are Clean Room Used In Data Recovery?
Clean rooms used are rooms that have been designed to reduce the level of particulates in the air like dust and airborne microbes. Clean room construction employs filters extensively. Staff would usually have to enter clean rooms through airlocks and wear protective gear while working inside the rooms.
For professional data recovery companies a clean room is an essential asset as hard drive repair often requires the use of exceptionally clean working conditions.
External air literally has to go through a range of extremely fine filters to ensure that any airflow into the clean room is totally clear of any harmful particles and often secondary systems are also in place with directed airflows to reduce the risk of internally generated contaminants coming into contact with the actual workbench area or surface.
There are different “classes” of clean rooms, with each class limiting permissible different numbers of particles per cubic meter, as well as the maximum sizes particles. Thus a Class 1 clean room is one where the number of particles should not exceed 1000 particles per cubic meter.
Clean rooms are not only used in data recovery operations though, they are widely found in all manner of industries ranging from medical labs to pharmaceutical manufacturing plants and of course electronics manufacturing plants. Rooms can be a few feet square or can encompass an entire manufacturing plant area depending on the operation in question.
Why Are Clean Rooms Essential For Hard Drive Repair?
The internal components of a hard drive and in particular the disk platters (many drives have more than one) are exceptionally susceptible to further damage from airborne particulates once opened. Even the most microscopic particles can further damage the extremely sensitive platter surfaces as can damage from ESD, so a clean room environment is essential for a success repair in many instances.
With each generation of disks, data is packed more and more densely on the disk platters. It is thus increasingly important that data recovery be attempted in exceptionally clean rooms.
Another consideration for using a clean room though is the warranty on your drive that will be made invalid if not repaired by an authorised agent or in a clean room environment although in reality the value of the accumulated data on most drives is by far massively more valuable than the drive itself, so all the more reason to ensure that it is only worked on in the cleanest of environments to prevent further damage.
Thus clean rooms are necessary for data recovery on both performance and product warranty considerations. Disk drives should only be opened in clean rooms and kept there until the recovery is complete and the drive is closed. Data storage media are getting packed with data more and more densely with each new generation of drives. It is thus extremely important to attempt data recovery in exceptionally dust free rooms.
If you need to hand over your hard drive to a data recovery services company check the validation of their clean room. At the very least it should be class 100 certified although the top companies will have invested in even better standards, for example ISO class 3.
The Camcorder World
A camcorder can be used to make memories for future generations to enjoy. Previously, the world of record and memory-keeping was limited to still pictures or text. Today, individuals can use camcorders to store actual events, as they take place. Capturing memories has never been quicker or simpler thanks to the invention of the high tech, video recorders that are seen in today’s world.
In 1980, the inventor by the name of Jerome Lemelson received the first patent on the now popular camcorder. He had tried to patent the idea in 1977, but the U.S. patent office rejected the idea, claiming that it was too far fetched. Little did they understand about the revolution that the video recorder would undertake in so short of a time frame. In addition to the invention of camcorders, Lemelson also invented components for the ATM, the barcode scanner, and the Walkman. The world of technology and digital video production has come a long way thanks to Jerome Lemelson and his incredible mind.
When a person thinks of camcorders, they most likely do not consider the internal components. Inside those small digital handycam recorders are many components, including a mini VCR. The handy cams are so tiny that one may have a hard time believing this, but in every type of camcorder, this crucial component exists. Also included inside is a CCD, which helps measure the light used to show the images, as well as lens and motors that deal with zoom, focus and aperture.
A camcorder is a wonderful item for a person to own. This video recorder allows a person to capture important life events with just a click of a few buttons. A person can capture their wedding, the birth of a child or basically their entire lives for future generations. The media will not fade into nothing, like the still camera pictures of yesteryear. Recording special events has never been more technologically advanced!
Disaster Recovery Plans – Does Your Business Have One?
Many businesses risk grave losses due to failures and disasters yet continue to depend on un-validated tape backups should they need to recover from a major outage. Implementing a disaster recovery plan can be time consuming and daunting; to the point which many simply put it off.
Through some basic steps, businesses can better protect themselves against catastrophic data loss, these steps include:
- · Why do I need a Disaster Recovery Plan (DR) plan?
- · Defining and planning
- · Implementation
- · Testing
There are numerous disasters that could befall any business at any time in reality, and most of these will be unforeseen, the UK has in recent times suffered from unprecedented floods and in the US ice storms and power failures are the most recent issues, all the more reason for ensuring you have a disaster recovery plan of some description ready to roll out.
One of the most important aspects of a disaster recovery program is to ascertain what are the critical elements of your business. This will vary from business to business so for some it could be to ensure that data subject to long term availability due to legislation is always protected and for others it could be that the value of the business is held in the company CRM database. Whatever the case make sure your DR plan encompasses your most valuable assets at the very least.
Another important aspect of your plan should be that the business downtime should be a short as possible, an hour lost in a small business with a few employees can be manageable but if you have hundreds of employees then even an hour downtime is equivalent to weeks of lost work cumilitavely.
Remote data backup is a useful tool to have in your disaster recovery portfolio. Many companies will have data and tape back up data stored on company premises. In the event of a major catastrophe such as a fire all company data could be lost. Utilising offsite remote data backup ensure that data is still safe and could even be accessed from another location if required.
No two companies are the same; it pays to plan your implementation. A documented project plan can help with your disaster recovery procedures, A project plan allows it to be broken down into more manageable chunks. With proper planning you can avoid some of the pitfalls and ensure nothing in left unaccounted for and will prevent having to go back.
And last but not least test test test! Sadly numerous stories abound of companies that have set up a DR plan of sorts then simply assumed it would work. You need to ensure your plan is robust and tested on a regular basis to ensure key personnel are practiced in its implementation.
Disaster recovery planning, data recovery service and online data backup protocols should be in place for every business that has critical business data and systems. Don’t wait until it is to late and disaster has already struck.
