Understanding Image Stabilization
“Image stabilization helps to steady the image projected back into the camera by the use of a “floating” optical element” -Vincent Bockaert, DPReview. But, what does it means to the media enthusiastic when we get hands on with any type of video or image recording equipment. In essence, when recording images or video there is the possibility of having shaking elements, whether is because of our pulse and the way the body works or environment elements like uneven roads, wind, etc.
The first reaction to image stabilization problems should be identifying the solution to the given problem. For electronics companies was easy to come up with an idea that has resolve this for us in a way. The image stabilization function is present in both electronic and physical elements of our equipment, more equipment have included some type of electronic image stabilization. These electronic options are good for the low-end consumer electronics and seem to get better.
Examples of electronic image stabilization (EIS) are being implemented successfully through the light sensing ships inside video and photo electronics. Often, the known CCD chips carry together the image stabilization piece attached in one same unit. While EIS is not the best method of applying this concept is better than to have nothing inside your equipment to prevent shakiness. On of the attributes of EIS is that it gets enhanced as you zoom into subjects, when you use the zoom of your camera shakiness is to happen easily therefore this function is very helpful.
The way EIS work is by sensing movement on the equipment, this is possible through motion sensors that detect movement. Inside the chip everything sums down to mathematical equations, when you focus on an image that image is recorded by the sensor momentarily and any changes to it activate the system to have the EIS to the math for us. When you go shopping for a new not too expensive camera there are no differentiation between chips therefore test your equipment, move the camera from side to side (also known as panning) to get a clue whether the EIS is good or not.
The optical image stabilization (OIS) is found on more expensive equipment, these days that translate to any camera over $400 price tag. The main advantage and the reason behind the why is better than EIS is because it manipulates the images or videos before it gets recorded. Low-end equipment often do not carry these type of feature, and is possible to find it in equipment like digital cameras and camcorders but also, you can find this in lenses for these electronic equipment. Camcorders with OIS are considered of better quality than those without it, one way to get the better equipment with the better feature is spending some money unfortunately.
Digital cameras like D-SLR often have these OIS capabilities but to make it more exciting lenses available for D-SLR’s also have OIS integrated. Lenses with OIS are way more expensive than those that do not include the mentioned feature, but also they are the favorites for sports photographers and wild life photographers. When you take into consideration that the more you zoom into a subject to more image stabilization you need, then makes sense to think that the higher the zoom range you need to shoot the more money you are going to spend on gear.
There are lots of discussions on which camera companies have the better zoom lenses, what I have read around is that Nikkor lenses are far superior from the rest out there but they tell that to a Canon camera lover, they would disagree immediately. Test before you buy, can’t say it better. Whatever your activities are aim for the best equipment you can get on your budget, save before just getting whatever.
There is plenty information around the web to make the right choice. Find out more by visiting my website at www.lumencreativegroup.com, email me for questions at lumencreativegroup@gmail.com, also participate on our forums for discussion over what’s good and what not. Thanks.
