I'm saving up to buy a new camera to pursue my interest in photography. In photography, you can create art by recording light on an image.
Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.

Photography
Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing.
Rollei
Rollei () was a German manufacturer of optical instruments founded in 1920 by and in Braunschweig, Lower Saxony, and maker of the Rolleiflex and Rolleicord series of cameras. Later products included specialty and nostalgic type films for the photo hobbyist market. Originally named "Werkstatt für Feinmechanik und Optik, Franke & Heidecke", the company renamed into "Rollei-Werke Franke & Heidecke GmbH" in 1972, "Rollei-Werke Franke & Heidecke GmbH & Co. KG", in 1979, and "Rollei Fototechnic GmbH & Co. KG" in 1981. After being purchased in 1995 by Samsung Techwin, part of the South Korean Samsung Group, it was sold back to its internal management in 1999.
Cinematography
Cinematography (also called "Direction of Photography") is the science or art of motion-picture photography by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as film stock. Typically, a lens is used to repeatedly focus the light reflected from objects into real images on the light-sensitive surface inside a camera during a questioned exposure, creating multiple images. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a video file for subsequent display or processing.
Color photography
Color (or colour) photography is photography that uses media capable of reproducing colors. By contrast, black-and-white (monochrome) photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray. In color photography, electronic sensors or light-sensitive chemicals record color information at the time of exposure. This is usually done by analyzing the spectrum of colors into three channels of information, one dominated by red, another by green and the third by blue, in imitation of the way the normal human eye senses color. The recorded information is then used to reproduce the original colors by mixing various proportions of red, green and blue light (RGB color, used by video displays, digital projectors and some historical photographic processes), or by using dyes or pigments to remove various proportions of the red, green and blue which are present in white light (CMY color, used for prints on paper and transparencies on film).
Pictorialism
Pictorialism is the name given to an international style and aesthetic movement that dominated photography during the later 19th and early 20th centuries. There is no standard definition of the term, but in general it refers to a style in which the photographer has somehow manipulated what would otherwise be a straightforward photograph as a means of "creating" an image rather than simply recording it. Typically, a pictorial photograph appears to lack a sharp focus (some more so than others), is printed in one or more colors other than black-and-white (ranging from warm brown to deep blue) and may have visible brush strokes or other manipulation of the surface.
Alfred Stieglitz
Alfred Stieglitz (January 1, 1864 – July 13, 1946) was an American photographer and modern art promoter who was instrumental over his fifty-year career in making photography an accepted art form. In addition to his photography, Stieglitz was known for the New York art galleries that he ran in the early part of the 20th century, where he introduced many avant-garde European artists to the U.S. He was married to painter Georgia O'Keeffe. Stieglitz was born in Hoboken, New Jersey, the first son of German-Jewish immigrants Edward Stieglitz (1833–1909) and Hedwig Ann Werner (1845–1922). His father was a lieutenant in the Union Army.
Camera
A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies. The camera is a remote sensing device as it senses subjects without any contact  . The word "camera" comes from "camera obscura", which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface. The modern photographic camera evolved from the camera obscura. The functioning of the camera is very similar to the functioning of the human eye.

What photography do you like best?
0_Wizard
I really like digital photography where an electronic image sensor produces a charge for each pixel which is then stored as a digital image file.
With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing.

Digital camera
A digital camera or digicam is a camera that captures photographs in digital memory. Most cameras produced today are digital, and while there are still dedicated compact cameras on the market, the use of dedicated digital cameras is dwindling, as digital cameras are now incorporated into many devices ranging from mobile devices to vehicles. However, expensive, high-end, high-definition dedicated cameras are still commonly used by professionals. Digital and movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, just as with film but the image pickup device is electronic rather than chemical.
Digital photography
Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film. The captured images are digitized and stored as a computer file ready for further digital processing, viewing, digital publishing or printing. Until the advent of such technology, photographs were made by exposing light sensitive photographic film and paper, which was processed in liquid chemical solutions to develop and stabilize the image. Digital photographs are typically created solely by computer-based photoelectric and mechanical techniques, without wet bath chemical processing.
Digital single-lens reflex camera
A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor. The traditional alternative would be to have a viewfinder with its own lens, hence the term "single lens" for this design. By using only one lens, the viewfinder of a DSLR presents an image that will not differ substantially from what is captured by the camera's sensor.
Image sensor format
"Note: If you came here to get a quick understanding of numbers like 1/2.3, skip ahead to table of sensor formats and sizes. For a simplified discussion of image sensors see image sensor." In digital photography, the image sensor format is the shape and size of the image sensor. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular sensor. Because the image sensors in many digital cameras is smaller than the 24 mm × 36 mm image area of full-frame 35-mm cameras, a lens of a given focal length will give a narrower field of view on such cameras.
Raw image format
A camera raw image file contains minimally processed data from the image sensor of either a digital camera, image scanner, or motion picture film scanner. Raw files are named so because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor. Normally, the image is processed by a raw converter in a wide-gamut internal color space where precise adjustments can be made before conversion to a "positive" file format such as TIFF or JPEG for storage, printing, or further manipulation. This often encodes the image in a device-dependent color space.
Image stabilization
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation. It is used in image-stabilized binoculars, still and video cameras, astronomical telescopes, and also smartphones, mainly the high-end. With still cameras, camera shake is particularly problematic at slow shutter speeds or with long focal length (telephoto or zoom) lenses.

Digital is much different from the old film cameras but I think film delivers a better picture

One thing I like about digital photography is that the images can be produced without wet bath chemical processing, so I can produce them at home.
Digital photographs are typically created solely by computer-based photoelectric and mechanical techniques, without wet bath chemical processing.

Digital imaging
Digital imaging or digital image acquisition is the creation of photographic images, such as of a physical scene or of the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing, and display of such images. Digital imaging can be classified by the type of electromagnetic radiation or other waves whose variable attenuation, as they pass through or reflect off objects, conveys the information that constitutes the image. In all classes of digital imaging, the information is converted by image sensors into digital signals that are processed by a computer and made output as a visible-light image.

Conservation and restoration of photographs
The Conservation and restoration of photographs is the study of the physical care and treatment of photographic materials. It covers both efforts undertaken by photograph conservators, librarians, archivists, and museum curators who manage photograph collections at a variety of cultural heritage institutions, as well as steps taken to preserve collections of personal and family photographs. It is an umbrella term that includes both preventative preservation activities such as environmental control and conservation techniques that involve treating individual items. Both preservation and conservation require an in-depth understanding of how photographs are made, and the causes and prevention of deterioration.

Breathalyzer
A breathalyzer or breathalyser (a portmanteau of "breath" and "analyzer/analyser") is a device for estimating blood alcohol content (BAC) from a breath sample. Breathalyzer is the brand name (a genericized trademark) for the instrument that tests the alcohol level developed by inventor Robert Frank Borkenstein. It was registered as a trademark on May 13, 1954, but many people use the term to refer to any generic device for estimating blood alcohol content . A 1927 paper produced by Emil Bogen, who collected air in a football bladder and then tested this air for traces of alcohol, discovered that the alcohol content of 2 litres of expired air was a little greater than that of 1 cc of urine.

Producing them at home is also cheaper.  Is that true?
0_Wizard
Yes- you can print them images either with a regular printer or photo printer, rather than having to use liquid chemical solutions and light sensitive paper. It's a big saver.
Until the advent of such technology, photographs were made by exposing light sensitive photographic film and paper, which was processed in liquid chemical solutions to develop and stabilize the image.

Printer (computing)
In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper. The first computer printer design was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; his mechanical printer design was not built until 2000. The first electronic printer was the EP-101, invented by Japanese company Epson and released in 1968. The first commercial printers generally used mechanisms from electric typewriters and Teletype machines. The demand for higher speed led to the development of new systems specifically for computer use.

Dye-sublimation printer
A dye-sublimation printer is a computer printer which uses heat to transfer dye onto materials such as a plastic, card, paper, or fabric. The sublimation name was first applied because the dye was considered to make the transition between the solid and gas states without going through a liquid stage. This understanding of the process was later shown to be incorrect. There is some liquifying of the dye. Since then, the process is sometimes known as dye-diffusion, though this has not eliminated the original name. Chemical technology in Printing and Imaging Systems, ed. J A G Drake, 1993, pp 73-85 Many consumer and professional dye-sublimation printers are designed and used for producing photographic prints, ID cards, clothing, and more.
Daguerreotype
Invented by Louis-Jacques-Mandé Daguerre and introduced worldwide in 1839, daguerreotype was almost completely superseded by 1860 with new, less expensive processes yielding more readily viewable images. During the past few decades, there has been a small revival of daguerreotypy among photographers interested in making artistic use of early photographic processes. To make the image, a daguerreotypist would polish a sheet of silver-plated copper to a mirror finish, treat it with fumes that made its surface light sensitive, expose it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; make the resulting latent image on it visible by fuming it with mercury vapor; remove its sensitivity to light by liquid chemical treatment, rinse and dry it, then seal the easily marred result behind glass in a protective enclosure.
History of photography
The history of photography has roots in remote antiquity with the discovery of two critical principles, that of the camera obscura image projection and the fact that some substances are visibly altered by exposure to light, as discovered by observation. Apart from a very uncertain process used on the Turin Shroud there are no artifacts or descriptions that indicate that anyone even imagined capturing images with light sensitive materials before the 18th century. Around 1717 Johann Heinrich Schulze captured cut-out letters on a bottle of a light-sensitive slurry, but he apparently never thought of making the results durable.
History of printing
The history of printing goes back to the duplication of images by means of stamps in very early times. The use of round seals for rolling an impression into clay tablets goes back to early Mesopotamian civilization before 3000 BCE, they feature complex and beautiful images. In both China and Egypt, the use of small stamps for seals preceded the use of larger blocks. In China, India and Europe, printing on cloth certainly preceded printing on paper or papyrus. The process is essentially the same: in Europe special presentation impressions of prints were often printed on silk until the 17th century.
Compact photo printer
A compact photo printer is a stand-alone inkjet printer designed to produce 4×6 or 2×3 inch prints from digital cameras. It works without the use of a computer. It is also known as a portable photo printer or a snapshot printer. Compact photo printers came on the market shortly after the popularity of home photo printing took off in the early 2000s. They were designed as an alternative to developing photos or printing them on a standard inkjet photo printer. The majority of compact photo printers can only print 4" x 6" pictures. Given this limitation, they are not meant to replace standard inkjets.
