In the overall history of camera technology image stabilization is a rather recent development. Image stabilized lenses did not appear up until 1995 when Canon introduced the EF 75-300mm f/4 – 5.6 IS - the first image stabilized lens. IS or Image Stabilization is the acronym that Canon uses to refer to this technology. The technology was actually first seen on a previous lens, also made by Canon, the EF 300mm f/2.8L IS USM. This lens however did not reach the market up until 1999 which made the 75-300mm the first commercially produced image stabilized lens the world has seen.
Nikon calls this technology VR or Vibration Reduction. Other manufacturers use different other acronyms to label this technology. However, at the end of the day, they all mean the exact same thing. Though, in this case it is fair to say that all technologies are not the same. In fact all lenses are not optically stabilized either. There are some manufacturers who prefer to stabilize the sensor inside the camera rather than the lens! This happened because when image stabilization was developed digital sensors were not around and it would have meant either moving the physical film or the sensor. Canon and Nikon devised it was much easier to move the focusing elements inside the lens than moving the actual film.
Okay. Now we need to have a deeper understanding of how image stabilization works and why most professional and serious enthusiasts prefer to pay more for image stabilized lenses.

They make for wonderful sights and sounds for large gatherings, but fireworks also make great photographs. Its just about knowing how to capture such colorful images.
Shooting fireworks is fairly simple, but it takes some planning and equipment to do so. However, follow these tips and you too can have wonderful photos of those sky rockets.

In the earlier days photographers would have no way to change the ASA (ISO as it was called in those days) once they had loaded a film in their cameras. They were pretty much stuck with the film sensitivity until they changed it. That had a limiting effect on their creativity and it ensured that they were careful about their selection of film before heading out.
These days, digital photographers have a much easier time. They could change the ISO (light sensitivity of the sensor) just with the flick of a button. Cameras like the D800 comes with the added advantage of a greater dynamic range, allowing photographers to compose and make images that are closer to what they see with their naked eyes.
Yet, there are certain time-tested and useful tips that you need to know in order to nail good exposures in low light conditions. These are, in no way, alternatives to the ability of your camera to shoot in low light. Rather, these are complimentary to a high ISO capability.
