For centuries images have been projected onto surfaces. Artists used the camera obscura and camera lucida to trace scenes as early as the sixteenth century. These early cameras did not fix an image, but only projected images from an opening in the wall of a darkened room onto a surface, turning the room into a large pinhole camera. The phrase camera obscura literally means darkened room. The first photograph was an image produced in the year eighteen twenty-six by the French inventor Nicephore Niepce on a polished pewter plate covered with a petroleum derivative called bitumen of Judea. Produced with a camera, the image required an eight-hour exposure in bright sunshine. Niepce then began experimenting with silver compounds based on a Johann Heinrich Schultz discovery in the year seventeen twenty-four that a silver and chalk mixture darkens when exposed to light.

Color photography was explored throughout the eighteen hundreds. Initial experiments in color could not fix the photograph and prevent the color from fading. The first permanent color photo was taken in the year eighteen sixty-one by the physicist James Clerk Maxwell. One of the early methods of taking color photos was to use three cameras. Each camera would have a color filter in front of the lens. This technique provides the photographer with the three basic channels required to recreate a color image in a darkroom or processing plant. Russian photographer Sergei Mikhailovich Prokudin-Gorskii developed another technique, with three color plates taken in quick succession.

Practical application of the technique was held back by the very limited color response of early film; however, in the early nineteen hundreds, following the work of photo chemists such as H. W. Vogel, emulsions with adequate sensitivity to green and red light at last became available.

Digital photography, as opposed to film photography, uses electronic devices to record the image as binary data. This facilitates storage and editing of the images on personal computers, and also the ability to show and delete unsuccessful images immediately on the camera itself. Digital cameras now out sell film cameras and include features not found in film cameras such as the ability to shoot video and record audio. Some other devices, such as mobile phones, now include digital photography features.

Traditional photography was a considerable burden for photographers working at remote locations without access to processing facilities. With increased competition from television there was pressure to deliver their images to newspapers with greater speed. Photo journalists at remote locations would carry a miniature photo lab with them and some means of transmitting their images down the telephone line. In the year nineteen eighty-one Sony unveiled the first consumer camera to use a CCD for imaging, and which required no film, the Sony Mavica. While the Mavica did save images to disk, the images themselves were displayed on television, and therefore the camera could not be considered fully digital. In the year nineteen ninety, Kodak unveiled the DCS one hundred, the first commercially available digital camera. Its cost precluded any use other than photojournalism and professional applications, but commercial digital photography was born.

The quality of a digital image is the sum of various factors, many of which are similar to film cameras. Pixel count, typically listed in mega pixels, millions of pixels, is only one of the major factors, though it is the most heavily marketed. Pixel count metrics were created by the marketing organizations of digital camera manufacturers because consumers can use it to easily compare camera capabilities. It is not, however, the major factor in evaluating a digital camera. The processing system inside the camera that turns the raw data into a color balanced and pleasing photograph is the most critical, which is why some four plus mega pixel cameras perform better than higher end cameras.

Photographic training and the display of finished photographs may also be accommodated in a photographic studio. Accordingly, the workspace may possess a darkroom, storage space, a studio proper, where photographs are taken, and a display room, as well as space for other related work.

As a corporate entity, a photographic studio is a business owned and represented by one or more photographers, possibly accompanied by assistants and pupils, who create and sell their own and sometimes others’ photographs. Since the early years of the 20th century the corporate functions of a photographic studio have increasingly been called a photographic agency, leaving the term photographic studio to refer almost exclusively to the work space.

A darkroom is a workspace, usually a separate area in a building or a vehicle, made dark to allow photographers to use light sensitive materials to develop film and photographic paper to make photographic prints. Darkrooms have been used since the late 19th century for black and white photography. Using black and white film, photographers could control every step of the photographic process. Due to the complexity of processing color film and printing color photographs, and to the rise, first of Polaroid technology and later digital photography, darkrooms are decreasing in popularity.

However you wish to start photography is not limited by the classes you take, you can achieve much of this skill with an earnest desire to learn and understand, but taking professional courses can give you the experience that can lead to a possible profession in the realm of photography. Sometimes it can be frustrating to grasp the concepts inherent in taking pictures, and on a simplistic level, it can be difficult to take photography to a serious level of skill if you feel that are lacking any particular knowledge. This need not be so, though, if you participate in an adequate amount of research outside of a classroom setting.

Experience can do the most for any outlook that fits photography into the spectrum of artistic understanding, all that is required is a camera and a little know-how on most accounts, but a few classes can really make the difference in creating a portfolio that evoke a truly professional regard for your work. It can take a long time to find your own eye for such things as perspective, and many of the other requisites for understanding the artistic qualities in photography, though it shouldn’t take a lifetime to find the perfect shot for your photo album. All these ideas can contribute to the overall interest you decide to give a subject.

There are short classes and courses that will allow for you to come to grips with what your own personal interpretation of what photography will mean for you, or perhaps to have an outlook that will be projected more through your photographs, each of these places and gatherings will allow you to add more information to what you already know about the idea of photography at all. To change what you believe to be an inferior skill with the camera into one of professional outlook, whether you happen to wish to have a career in photography, or just improving your own personal skill in using a camera.

The Internet can be a way that you could start you quest for knowledge, there are possibly even courses that you can take online that will give you the same amount of improvement that you would find in a classroom somewhere, but there is nothing that really compares with the experience in becoming more professional in your abilities in working with the camera. Whether the camera is digital or one that requires the use of film to create images, should make no difference more than with technical details, but the choice of tool in these pursuits is up to you as the phototgrapher.

A film base is a transparent substrate which acts as a support medium for the photosensitive emulsion that lies atop it. Despite the numerous layers and coatings associated with the emulsion layer, the base generally accounts for the vast majority of the thickness of any given film stock. Historically there have been three major types of film base in use: cellulose nitrate, cellulose acetate and polyester.

A film format is a technical definition of a set of standard characteristics regarding the image capture of still film or the image capture and projection of motion picture film. In the latter case, it may also encompass audio parameters. These characteristics usually include the film gauge, pull down method, lens anamorphosis and film gate or projector aperture dimensions, all of which need to be defined for photography as well as projection, as they may differ.

A filter is a camera accessory consisting of an optical filter that can be inserted in the optical path. The filter can be a square or rectangle shape mounted on a holder accessory or, more commonly, a glass or plastic disk with a metal or plastic ring frame, which can be screwed in front of the lens. Filters allow added control for the photographer of the images being produced. Sometimes they are used to make only subtle changes to images; other times the image would simply not be possible without them.

A flash is a device that produces an instantaneous flash of light at a color temperature of about five thousand five hundred kilowatts to help illuminate a scene. While flashes can be used for a variety of reasons they are mostly used to illuminate scenes that do not have enough available light to adequately expose the photograph. The term flash can either refer to the flash of light itself, or as a colloquialism for the electronic flash unit which discharges the flash of light. The vast majority of flash units today are electronic, having evolved from single use flash bulbs and inflammable powders.
