WHAT IS ?

the camera is a device used to capture images or photographs. It is an ancient mechanism for projecting images, in which an entire room played the same operations as a current camera inside, with the difference that there was no chance of saving the image unless it is manually drawn at the time. The current cameras are combined with sensitive elements (film or sensor) to the visible spectrum or other portions of the electromagnetic spectrum, and its primary use is to capture the image in the visual field.

Cameras consist of a closed dark room, with an opening at one end so you can come light, and a flat surface imaging or display to capture the light at the other end. Most cameras have a lens shaped object located in front of the camera aperture to control incoming light and to focus the image, or part of the image. The diameter of this opening (known as opening) usually modified with a diaphragm, although some targets have fixed opening

HISTORY• The first photographer was Nicéphore Niépce in 1826, using a camera made of wood made

by Charles and Vincent Louis Jacques Chevalier in Paris.

• In the nineteenth century many types of cameras were designed. For example, suitable for stereoscopic photographs cameras; whose stereopsis finally had to look with an appropriate viewer, to view three-dimensional or relief effect. A typical stereoscopic camera had two goals, to obtain simultaneously two very similar images, but not identical, from two points of view very close. Actually it was inspired by the human binocular vision.

• Other different cameras studio cameras were some of the time when the portraits were popular in card format (between 1860 and 1880). These cameras could have four or more goals, for several portraits in the same glass negative. Thus the positive (contact) was faster, because in a single sheet of paper the portraits were obtained; that only they had to be cut and assembled in different individual cards.

ADVANTAGES

• Its dimensions are so small that you can carry and transport comfortably inside a pocket and used anywhere, either outdoors or indoors, as most have built-in flash.

• The high end are bulkier and heavier, but offer greater possibilities for better results with a value set. Moreover, for amateur photographers and for the less seasoned these cameras also offer the ability to focus and make adjustments lens aperture and shutter speed in fully automatic mode.

• In addition to the LCD (liquid crystal display) that own and allow to frame and focus the image, some digital camera manufacturers still maintain the traditional optical viewfinder, although the latter option is disappearing in the latest models of low and mid-range that are coming to the market.

• Most digital cameras have "image stabilizer" to correct any involuntary movement we incur when taking a picture, provided there is sufficient lighting.

• If the visionar photo taken immediately after were not satisfied with the result, you can erase and repeat again provided the same conditions and the possibility of doing so remain.

• Allow to obtain photos printed on paper almost immediately and in the home using a photo-quality printer attached to the computer or not.

• .

• Some digital cameras, in addition to their normal job to take pictures, also can record small video sequences. Some models can even record the sound synchronized with the images.

• The compact high-end cameras allow manual adjustment and can also accept the use of different optional attachments that make them more complete as, for example, an additional external flash lamp more power and light scope, or supplements that are coupled to target take pictures type macro to a closer distance to the object, or also increase the distance of the telephoto range.

• Digital photos can be retouched and / or fix on the computer before publishing on the Internet, send e-mail, or print them on paper.

• Images stored on mass storage devices such as hard drives, CDs, DVDs, or flash memory cards, theoretically not deteriorate or lose quality over time, unlike what happens with film negatives or photographic slides when appropriate conservation measures are not taken. However, it is advisable to perform at least two identical copies of all digital photos, as any mass storage device, for sure, can fail over the years. Its dimensions are so small that you can carry and transport comfortably inside a pocket and used anywhere, either outdoors or indoors, as most have built-in flash.

• The high end are bulkier and heavier, but offer greater possibilities for better results with a value set. Moreover, for amateur photographers and for the less seasoned these cameras also offer the ability to focus and make adjustments lens aperture and shutter speed in fully automatic mode.

• In addition to the LCD (liquid crystal display) that own and allow to frame and focus the image, some digital camera manufacturers still maintain the traditional optical viewfinder, device, for sure, can fail over the years.

DISADVANTAGES• high price in compact high-end models and especially reflex, although lately it has considerably reduced

in mid-range cameras, getting closer and closer to having the above conventional analog cameras within that own range.

• Great potential for accidental damage LCD liquid crystal display, especially those with larger (2.5 to 3 inches), leaving the camera completely out of service.

• High consumption of batteries when we keep on for a long time the LCD viewfinder.

• Quick change of models of the same brand of camera, which leaves out of date previous models

• Emergence of a lot of noise image sensors in cameras that use low quality, especially when shooting in low light or high ISO values are used.

• Accumulation of hundreds or thousands of photographs in digital form, without which we print on photo paper, so in many cases are relegated to oblivion when not properly organize mass storage devices.

• Certain feeling of nostalgia by those advanced amateur photographers or professionals who were responsible for revealing themselves manually, the photos in your own photo lab or in makeshift home "darkrooms".
