Camera is one of the most exciting and amazing inventions of modern science.It is a device which records images on paper or on the film.These images may be referred as still photographs or motion images which are often referred as videos or movies.

The word is derived from the Latin word ‘Camera Obscura’ which means ‘dark room’ which was an initial mechanism for projecting images.These are meant to work with the visible or with the electromagnetic spectrums of light.This word was used by Johannes Kepler who was a German astronomer early in the seventeenth century.

This fabulous thing consists of an enclosed hollow with an opening at the other end for allowing the light to enter along with a viewing or recording surface for catching the light from the other end.Camera works on the principle of the law of the optics that is light travels in a straight line and does not scatter but cross and appear on flat surface as an upside down image.

The very first machine of this type was invented by the Chinese philosopher Mo-Ti during fifth century.He made a note of an inverted image that was produced by the light rays, when this light was allowed to pass through the pin hole into a darkened chamber.The darkened chamber was named as ‘collecting place’ or ‘treasure room’ by Mo-Ti.

The quality of the images of the camera was not so good up to sixteenth century but with the introduction of convex lens into the aperture, the quality of the image was improved.

The modern day camera makes use of glass lenses for focusing and capturing light within a flash and facilitating us to magnify these images.The images so produced exhibit each and every detail as compare to the initial films.These also have digital sensors which could be sometimes replacing the film.Most of the modern type exhibits shutters for restricting the light from reaching the film or sensor just by clicking a button.They also exhibit a very intense flash for getting the brighter images and to capture every detail of the picture.

Digital Cameras are one of the most advanced types which are very compact, slim, sleek and can be carried quite easily during the outings.Most of the digital camera manufacturing brands offer an array and are packed with the latest technologies for getting the most real images.The quality of the images taken by this excellent device is distinguished by the resolution of pixels of the camera and image sensors.

They are available in small and large sizes but the one with cheaper rate or pocket size don’t have much features as compare to the larger one, but these are very convenient to handle or to carry.Despite of their sizes most of the cameras deliver high quality images.

Most of the leading brands such as Nikon, Bushnell, Oympus and Casio offer the digital cameras that exhibit technological innovations.You can find one of the most appropriate types of camera from the leading brands according to your choice and preference.
