Painting with light.

Is an ambition photographer similar to a motivation speaker because I need more ambition to photograph? Personally motivation speakers bore and confuse me with their antics such as ripping up a phone book in one single tear, or blowing up rubber glove which has been pulled over their face, now how are antics like that going to keep anyone off of drugs? I swear to god that if an ambition photographer starts off his seminar by trying to empower the audience by ripping up a phone book I am going to leave.

understanding words bearing directly to photos is a lot much less significant than information them. in case you do no longer understand a thank you to apply appropriate composition then throwing the be conscious available won't assist you. additionally if somebody asks you what shutter speed you used for a particular photograph you will look stupid in case you respond via asserting the two-thirds rule or f/5.6. do no longer purely learn the words, learn what they mean.

Photography is the process of making pictures by means of the action of light. Light patterns reflected or emitted from objects are recorded onto a sensitive medium or storage chip through a timed exposure. The process is done through mechanical, chemical or digital devices known as cameras.


Lens and mounting of a large-format cameraWikibooks has more about this subject:
PhotographyThe word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally the product of photography has been called a photograph. The term photo is an abbreviation; many people also call them pictures. In digital photography, the term image has begun to replace photograph. (The term image is traditional in geometric optics.)

[edit] Photographic image-forming devices
A camera or camera obscura is the image-forming device and photographic film or a digital storage card is the recording medium, although other methods are available. For instance, the photocopy or xerography machine forms permanent images but uses the transfer of static electrical charges rather than photographic film, hence the term electrophotography. Rayographs published by Man Ray and others are images produced by the shadows of objects cast on the photographic paper, without the use of a camera. Objects can also be placed directly on the glass of a scanner to produce digital pictures.

Photographers control the camera and lens to expose the light recording material (usually film or a charge-coupled device; a complementary metal-oxide-semiconductor may also be used) to the required amount of light. After processing, this produces an image.

The controls include:

Focus of lens
Aperture of the lens (amount of light allowed to pass through the lens)
Focal length and type of lens (telephoto, macro, wide angle, or zoom)
Filters, or scrims placed between the subject and the light recording material, either in front of or behind the lens
Duration of exposure (or shutter speed)
Sensitivity of the medium to light intensity and color/wavelength
The nature of the light recording material, for example its resolution as measured in pixels or grains of silver halide
Camera controls are inter-related, as the total amount of light reaching the film plane (the "exposure") changes proportionately with the duration of exposure, aperture of the lens, and focal length of the lens (which changes as the lens is focused, or zoomed). Changing any of these controls alter the exposure. Many cameras automatically adjust the aperture of the lens to account for changes in focus, and some will accommodate changes in zoom as well.

The duration of an exposure is referred to as shutter speed, often even in cameras that don't have a physical shutter, and is typically measured in fractions of a second. Aperture is expressed by an f-number or f-stop (derived from focal ratio), which is proportional to the ratio of the focal length to the diameter of the aperture. If the f-number is decreased by a factor of , the aperture diameter is increased by the same factor, and its area is increased by a factor of 2. The f-stops that might be found on a typical lens include 2.8, 4, 5.6, 8, 11, 16, 22, 32, where going up "one stop" doubles the amount of light reaching the film, and stopping down one stop halves the amount of light.

Exposures can be achieved through various combinations of shutter speed and aperture. For example, f/8 at 1/125th of a second and f/4 at 1/500th of a second yield the same amount of light. The chosen combination has an impact on the final result. In addition to the subject or camera movement that might vary depending on the shutter speed, the aperture (and focal length of the lens) determine the depth of field, which refers to the range of distances from the lens that will be in focus. For example, using a long lens and a large aperture (f/2.8, for example), a subject's eyes might be in sharp focus, but not the tip of the nose. With a smaller aperture (f/22), or a shorter lens, both the subject's eyes and nose can be in focus. With very small apertures, such as pinholes, a wide range of distance can be brought into focus.

Image capture is only part of the image forming process. Regardless of material, some process must be employed to render the latent image captured by the camera into the final photographic work. This process consists of two steps, development, and printing.

During the printing process, modifications can be made to the print by several controls. Many of these controls are similar to controls during image capture, while some are exclusive to the printing process. Most controls have equivalent digital concepts, but some create different effects. For example, dodging and burning controls are different between digital and film processes. Other printing modifications include:

Chemicals and Process used during film development
Duration of exposure (equivalent to shutter speed)
Printing Aperture (equivalent to aperture, but has no effect on depth of field)
Contrast
Dodging (Reduction in exposure of certain print areas, resulting in a lighter areas)
Burning (Increase in exposure of certain areas, resulting in darker areas)
Paper Quality (Glossy, Matte, Etc)
