Fujifilm announces the launch of the Fujifilm FinePix S9600 Megazoom digital camera, a refinement of the highly-regarded FinePix S9500, with 10.7x Fujinon optical zoom lens, 9 Megapixel Fujifilm Super CCD sensor, and class-leading ISO 80-1600 performance. The outgoing FinePix S9500 won an excellent reputation in a highly competitive area of the camera market and the Fujifilm S9600 builds on the quality of its predecessor with the addition of some significant extra features. The Fujifilm FinePix S9600 digital camera is aimed at serious hobbyist and enthusiast photographers who will benefit from its impressive optical zoom lens range, plus superb functionality, image quality and responsiveness.

Fujifilm S9600 camera - Zoom lens
The camera’s highly-specified Fujinon 10.7x (28-300mm - 35mm equivalent) zoom lens incorporates aspherical elements within its design, and has already distinguished itself in terms of its optical qualities. Not only does its versatile optical range offer all of the most popular focal lengths in one package, but the closed unit of body and lens ensures that the user will not have to contend with the issue of external specks of dust compromising image quality. The lens is easily controlled via a manual zoom ring, giving pinpoint accuracy when composing the image.

Fujifilm FinePix S9600 digital camera - Sensitivity
The new camera’s sensitivity range, made possible by Fujifilm’s Real Photo Processor enables users to achieve images in all lighting conditions, not just bright sunlight. Furthermore, the potential for blurry images is all but eliminated - unlike optical image stabilisation systems, the high ISO setting combats blur caused by both camera shake and subject movement.

Fujifilm S9600 Megazoom camera - Resolution
One of the FinePix S9600’s areas of differentiation from the FinePix S9500 are an increasement of sharpness and resolution achieved via improvements in new image processing algorithms: The image quality of this body and sensor combination has already gathered acclaim, and the Fujifilm FinePix S9600 delivers improvements in the area of resolution and image sharpness, giving enthusiast photographers a level of quality that will satisfy even the most critical inspection.

PHOTOGRAPHY

Photography is the art, science, and practice of creating pictures by recording radiation on a radiation-sensitive medium, such as a photographic film, or electronic image sensors. Photography uses foremost radiation in the UV, visible and near-IR spectrum. For common purposes the term light is used instead of radiation. Light reflected or emitted from objects form a real image on a light sensitive area (film or plate) or a FPA pixel array sensor by means of a pin hole or lens in a device known as a camera during a timed exposure. The result on film or plate is a latent image, subsequently developed into a visual image (negative or diapositive). An image on paper base is known as a print. The result on the FPA pixel array sensor is an electrical charge at each pixel which is electronically processed and stored in a computer (raster)-image file for subsequent display or processing. Photography has many uses for business, science, manufacturing (f.i. Photolithography), art, and recreational purposes.

The camera is the image-forming device, and photographic film or a silicon electronic image sensor is the sensing medium. The respective recording medium can be the film itself, or a digital electronic or magnetic memory.The basic principle of a camera or camera obscure is that it is a dark room, or chamber from which, as far as possible, all light is excluded except the light that forms the image. On the other hand, the subject being photographed must be illuminated. Cameras can be small, or very large the dark chamber consisting of a whole room that is kept dark, while the object to be photographed is in another room where the subject is illuminated. This was common for reproduction photography of flat copy when large film negatives were used. A general principle known from the birth of photography is that the smaller the camera, the brighter the image. This meant that as soon as photographic materials became sensitive enough (fast enough) to take candid or what were called genre pictures, small detective cameras were used, some of them disguised as a tie pin that was really a lens, as a piece of luggage or even a pocket watch (the Ticka camera).

In all but certain specialized cameras, the process of obtaining a usable exposure must involve the use, manually or automatically, of a few controls to ensure the photograph is clear, sharp and well illuminated. The controls usually include but are not limited to the following:

Control	Description
Focus	The adjustment to place the sharpest focus where it is desired on the subject.
Aperture	Adjustment of the lens opening, measured as f-number, which controls the amount of light passing through the lens. Aperture also has an effect on depth of field and diffraction – the higher the f-number, the smaller the opening, the less light, the greater the depth of field, and the more the diffraction blur. The focal length divided by the f-number gives the effective aperture diameter.
Shutter speed	Adjustment of the speed (often expressed either as fractions of seconds or as an angle, with mechanical shutters) of the shutter to control the amount of time during which the imaging medium is exposed to light for each exposure. Shutter speed may be used to control the amount of light striking the image plane; 'faster' shutter speeds (that is, those of shorter duration) decrease both the amount of light and the amount of image blurring from motion of the subject and/or camera.
White balance	On digital cameras, electronic compensation for the color temperature associated with a given set of lighting conditions, ensuring that white light is registered as such on the imaging chip and therefore that the colors in the frame will appear natural. On mechanical, film-based cameras, this function is served by the operator's choice of film stock or with color correction filters. In addition to using white balance to register natural coloration of the image, photographers may employ white balance to aesthetic end, for example white balancing to a blue object in order to obtain a warm color temperature.
Metering	Measurement of exposure so that highlights and shadows are exposed according to the photographer's wishes. Many modern cameras meter and set exposure automatically. Before automatic exposure, correct exposure was accomplished with the use of a separate light metering device or by the photographer's knowledge and experience of gauging correct settings. To translate the amount of light into a usable aperture and shutter speed, the meter needs to adjust for the sensitivity of the film or sensor to light. This is done by setting the "film speed" or ISO sensitivity into the meter.
ISO speed	Traditionally used to "tell the camera" the film speed of the selected film on film cameras, ISO speeds are employed on modern digital cameras as an indication of the system's gain from light to numerical output and to control the automatic exposure system. The higher the ISO number the greater the film sensitivity to light, whereas with a lower ISO number, the film is less sensitive to light. A correct combination of ISO speed, aperture, and shutter speed leads to an image that is neither too dark nor too light, hence it is 'correctly exposed,' indicated by a centered meter.
Autofocuspoint	On some cameras, the selection of a point in the imaging frame upon which the auto-focus system will attempt to focus. ManySingle-lens reflex cameras (SLR) feature multiple auto-focus points in the viewfinder.

Many other elements of the imaging device itself may have a pronounced effect on the quality and/or aesthetic effect of a given photograph; among them are:

Focal length and type of lens (normal, long focus, wide angle, telephoto, macro, fisheye, or zoom)
Filters placed between the subject and the light recording material, either in front of or behind the lens
Inherent sensitivity of the medium to light intensity and color/wavelengths.
The nature of the light recording material, for example its resolution as measured in pixels or grains of silver halide.
