Megapixel Myth

Many people have this misconception that the more megapixel rating in a camera the better quality photos it gives. But this is absolutely wrong. Mega-pixel rating describes only the size of the image, not its quality. Image quality is actually greatly affected by the image-sensor size installed on the camera. Larger the sensor better is the clicked image quality.

So, a 8-MP camera may outperform a 12-MP one, provided its image-sensor size is larger than the 12-MP one.

So, the next time you enter a shop to buy your next digicam, you know how to deal with the sales-man.

World's Fastest Camera

Japanese universities have created the world's fastest camera capturing at 4.4 trillion fps(frames per second).

At a mind-boggling 4.4 trillion frames per second (FPS), the new STAMP (Sequentially Timed All-optical Mapping Photography) system developed by two Japanese universities is claimed to be the world’s fastest camera. Taking pictures at a resolution of 450 x 450 pixels, the new image-capturing device is purported to be so fast that it can be used to photograph the conduction of heat, which travels at a speed equivalent to one-sixth the velocity of light.

Developed by researchers at the University of Tokyo and Keio University, the camera is said to use a method called femto-photography to capture images in a single burst without the need for repetitive measurements as used in other types of ultra-high-speed cameras. The team reports that this is achieved by using an ultra-short laser pulse split into a series of discrete separate pulses, each in different spectral bands, which illuminate the target object as successive flashes so that the entire scene may be captured using stroboscopic acquisition.
