In the past 2 decades the Remote Access technology has evolved many times to its perfection. Almost all companies and corporation now heavily rely on Virtual Private Networks (VPN) and the use of PC remote access for remotely accessing their VPN when outside their premises. Employees however are blessed with this technology as they can now work even at home without having to be at the office to use the VPN.However the use of this kind of software to access its VPN can burn a hole in the pockets due to the ever increasing prices and security concerns. A recent report by Infonetics showed that the VPN security market grew 11% this year and is expected to reach $6.6 billion by the year 2015. With interests shifting from just remote access to ‘secure remote access’, the remote access industry has had many innovative changes to help in the evolution of this technology and its uses.In over 20 years the evolution is going steady. Starting from a humble use by using a network of private modem pooled together via dial up connection and then followed by the use of internet IP protocols to navigate between the VPN & clients. Today the change has made is possible to access VPNs without needing to download and install special client software on the PC. This is quite convenient as it allows complete access from anywhere including smart phones by utilizing SSL, SSLv3 & the new player in the industry TLSv1 (Transport layer security). The use of TLS & DTLS has helped in balancing endpoint limitations and reducing risks against each user and the application. While these new security features may not mean much to home users of Remote Desktop Software, they are extremely useful for corporations that are active in industries where secure access to company data is a priority.The constant changes have its added disadvantages as well, since there are now hundreds of different PC remote access tools that are available in the market. Currently product selection involves SSL VPN tools to support secure web portal access to an application from limited endpoints. Better proxy access to common clients from many endpoints, secure port forwarding via java or ActiveX and network tunnels from endpoints with Installed TLS VPN clients are also used in certain software solutions. Therefore, before you make a decision as to which solution will be the best one for your company, you truly need to take the time to analyze your needs both in terms of what kind of access will be required (web based, PC applications, mobile applications, etc.) and the type of security mechanisms that you will need.
Spiffies Toothwipes have been clinically shown to reduce cavities in early childhood, so say the researchers at the University of California Dental School in a study which was presented to the American Academy of Pediatric Dentistry in June 2010. Spiffies are designed for children 3 months and older. Use Spiffies 3 times a day, especially before bedtime and after sugary snacks. Put a Spiffies packet in the fridge and once cooled, open packet, unfold towel and rub on your babies/toddlers gums to help soothe inflamed gums when teething. Spiffies are convienent for on the go, camping and trips as well. Click to see
Macro simply means big, micro means small now are they both the same thing ? In fact yes the two words point to the same realm of photography. Even close up photography is the same thing. That is getting small things to fill up the whole photograph. Now the scale of working is what differentiates them.Macro and Micro are used interchangeably for the realm of photography which aim at getting the object that is in the photograph to be the same size as the sensor. That is on a aps-c canon sensor the object would be of an area of 22.2×14.8mm. Let me get the idea a bit more clear, here we are talking about the sensor and not the photo. The sensor which is 22.2×14.8 (in our example) will be capturing a macro when the image falling on the sensor is of an area that is also 22.2mm x 14.8 mm. If you want to get an idea of what this size would be take a piece of paper draw a rectangle that is 22.2mm long and 14.8mm wide. Now cut along the rectangle to produce a paper with a hole. Now you are taking macro’s when you are capturing the area of the rectangle in the whole photograph, now we are talking in terms of photograph and not the sensor.
Why the two words macro and micro?This came out from the convention used by major brands. Nikon and some other brands use the word micro with lens that are true macro lens and Canon and many other brands use the word macro on lens that are true macro’s(1:1 or more). For convenience from now on we will use the word macro.Canon Macro 100mm F2.8Canon Macro 100mm F2.8Nikkor 60mm MicroNikkor 60mm MicroThe above images show a Macro model from Canon and a Micro model from Nikon.So is macro only 1:1?No, technically macro is 1:1 or more that is it can be 1:1 or 2:1 or 3:1 and so on. Usually we refer to anything above 2:1 as super macro photography.3:1 super macro of a flower3:1 super macro of a flowerThen what are close ups ?Magnified photo or photos that are not 1:1 but have high magnification ratios are called close up photos. Also some photographers refer to portraits as close ups. That is not part of the discussion on this article. Using diopters to achieve macro like effects on non macro lens can also be referred to as macro photography, but using reversed lens or bellows are actual macros and not close ups. Some diopters or close up filters do allow 1:1 macros but most are not 1:1 and thus this group of photographs also fall into close ups.Point and Shoots and macroMany point and shoot camera have the so called macro mode. These are actually close ups , most p&s(point and shoot) cameras have tiny sensors and their lens systems are made to be cheap than to be performers. So essentially it is impossible to achieve 1:! on a point and shoot or even a bridge. The reason being that the optics are not good enough and the sensor is too small. Even those cameras that can focus at distances less than 1 cm are not taking macros. So putting it simply P&S have close up modes and not macro modes. They call it macro because it resemble , a very vague resembles at that, to a macro.Also point and shoot cameras have a lot of mega pixels cramped onto a tiny sensor thus the quality of each pixel is very low compared to a sensor in a DSLR. Therefore the results that one can expect from the P&S’s so called macro mode is limited. This mode is good for the starting hobbyist who is not yet into wasting his whole salary on photographic equipment.
Is there anything else called Micro photography?Yes there is a realm of photography that attaches a camera to a microscope and then photographs of what is being seen in the viewfinder is taken. This is widely used in making textbooks and the like. There are some artists who make brilliant photographs using this technique.So next time your friend says his new point and shoot camera has Macro photography you know that he is talking about close up photography. Also when you see an image of an insect with brilliant details you can understand that it is a macro or a super macro photograph.Remember reading only gives you ideas going out and clicking pictures will make your pictures better.
