Latest Advanced Features in Digital Cameras

Digital cameras today are getting more high-tech as advanced features continue to be added to their systems. For those who are still not in the know, there now is the so-called face recognition and smile sensor technology. These were invented by one of the leading digital camera manufacturers Sony for its Cybershot DSC-T200 model.

With these two new features, camera owners are assisted in taking great photos especially of people during important gatherings. They ensure that faces and smiles are captured properly to create memorable keepsakes.

Face recognition

The face recognition technology was originally aimed to help entertainment robots of Sony to recognize the faces of the people who own them and their other family members. Eventually, it was applied to other products including many of Sony's audio visual equipment and now to digital cameras. Today, various manufacturers have also implemented this technology in their products notably in digicams and printers.

This particular function locates faces in every shot in a rapid manner. It then utilizes the camera controls to ensure the best setting for capturing the facial areas.

For printing purposes, the software of Sony's photo printer called PictureStation also applies auto correction processes before proceeding with the printing. It ensures that backlight is eliminated, skin color and focus are improved.

Smile detection

The auto smile shutter system of Cybershot has the ability to scan facial attributes of people, detect smiles and control the shutter timing in an automatic manner. This compliments the face detection technology by capturing images of people when a smile is detected on their faces. It then adjusts the focus and lighting settings for a great picture without even the red eye issue common in many digicams.

As it responds immediately to smiling faces, a digital camera then ensures that this happy mood is captured well and at the right time. And because it is an advanced feature, it is able to detect even just a slight tweak of the lips whenever cheeks and cheekbones go higher to a wide grin.

So if you're after capturing the smiling faces of friends and loved ones during special occasions or even just during ordinary days, then this is your best bet. You don't need to wait because the camera will automatically do the work for you. This smile detection technology is also now available in mobile phones in particular those with a built in camera such as the Sony Ericsson.

In Sony's Cybershot, these functions can easily be applied using its touch screen. If you're taking a photo of several people, for instance, you can choose the subject with the most attractive smile just by tapping inside the box that detects the face and smile. This kind of camera boasts of capturing 8 megapixel images worth printing and sharing on the internet with friends.

In addition to these two features, many digital cameras with built in flash nowadays are also able to perform other important functions when set on auto mode. These include improving low lighting conditions and stabilizing images to prevent blurred photos.

Understanding the SLR

It never fails to amaze me how cameras capture the life of a moment converting it into an image that can live long enough to tell a story for generations to come. Together with this curiosity goes my own personal dream of becoming an excellent photo taker. In this article, I will try to define the most basic mechanisms of an SLR.

One of the most popular gadgets, especially in the world of digital cameras, is the single -lens reflex or SLR. This camera uses a type of shutter which sits before the focal-plane. Other models have a different set-up, adding extra accessories to make sure that the light does not touch the film between exposures. One example is the shutter blinds in Hasselbald models to prevent light from reaching the film after every exposure. This is very practical during scenarios where there is abundance of light. An SLR camera utilizes a movable mirror in between the film and the lens during transmission of the image to the focusing screen.

An early model of SLR was already invented during the late 1800s, but its first practical use was during the Second World War when Exakta introduced the first 35 mm SLR. These cameras captured one of the most-telling and vivid pictures of life in the frontlines during the war in Europe. The early set included a waist-level viewfinder. Jeno Dulovits developed and introduced the eye-level viewfinders in Hungary during the 1940s. This was also the introduction of first instant-return type mirror so the photographer can see what he is taking at the time of the shot.

The passage of time and fast technological growth in film industry eventually rendered SLRs smaller. But it is not the size that matters as there were other significant changes that were slowly forming how SLRs should be built. Next stop is auto-focus. The first camera that featured this technology was seen in Pentax's ME-F SLR model. Light metering innovations came next. Together with auto-focus, light metering set a new demand in SLR construction. Many companies had to scrap old models to integrate these two innovations into their SLRs. LED and LCD screens came next. LCDs eventually reigned supreme due to its crisper view. Anti-shake features were also added later on making tripods redundant, and giving enough confidence to folks with shaking hands.

Digital SLRs were invented as early as 2000 spearheaded by Samsung, Canon, and Nikon. Digital SLRs became more popular over its film SLR cousin. Today digital SLRs uses memory cards to store captured images instead of films. Other models even have built-in hard drive storage space to store images. Still, many models feature more than one type of memory cards to store images.

Today, even novice photographers can take photos that can rival those taken by pros. One of the tricks I learned in using SLRs is by maximizing the flash. I can set the flash to either send out a single burst or multiple burst depending on the amount of light I need. Many models at present can even measure the amount of light in the lens and will automatically close the shutter after full exposure has been attained. In addition, today's SLRs are easy to use and come at great prices. It is the perfect tool for any budding photographer to capture once-in-a-lifetime moments with ease of a pro. In my opinion, SLRs deserve to be in any Technology news in any tech magazine today.

Using a Cable Amplifier Can Improve the Picture Quality of Your Television

The signal that comes into your home from your cable television provider can degrade and lose image quality when run through multiple splitters and network routers. Purchasing and installing an inexpensive signal booster or cable amplifier will greatly enhance the signal strength and quality on all of your televisions and computer connections. The boosters that are made for residential homeowners use normally come in a 75 version; amplifiers of this type can usually improve signal strength into an additional 100 feet of coaxial cable.

With most homes in the U.S. having at least three televisions, it is no surprise that the use of these boosters has been increasing over the last several years. In addition to the number of sets most homes have today, there is the fact that most television sets have either a VCR or a DVR connected to them, adding a little bit more impedance to the signal which could further degrade the quality of the signals running through them.

When considering where to install your booster one needs to simply investigate and determine where the cable is first coming into your home. Once you have established where the first cable outlet is located, you need to install the booster directly at that point. Your booster should be the first device in the network of coaxial cable lines running through out your home. If you install a booster at this junction you are going to ensure that every device from that point on to within 100 feet will gain the advantage of having a clear full strength signal feed.

With a little bit of forethought and planning you can be sure that when you purchase and install a cable amplifier each television set and DVR in your home will have a clear, strong, static free signal for your family to enjoy.
