photo enhancement by luxiva
There are various forms of photography; they include fine art photography, food photography, fashion, nude, forensic, travel, photo enhancement, sports etc, among many others. The various controls in a camera include focus, aperture, white balance, shutter speed, metering, ISO speed, and auto-focus point. Camera controls are inter-related. The total amount of light reaching the film plane changes with the duration of exposure, aperture of the lens, and, and the effective focal length of the lens. Changing any of these controls can alter the exposure. Many cameras may be set to adjust most or all of these controls automatically. This automatic functionality is useful for occasional photographers in many situations like picture enhancement.
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.
All photography was originally monochrome; most of these photographs were black and white. Even after color film was readily available, black-and-white photography continued to dominate for decades, due to its lower cost and its “classic” photographic look. It is important to note that some monochromatic pictures are not always pure blacks and whites, but also contain other hues depending on the process. The red-eye effect in photography is the common appearance of red pupils in color photographs of eyes. It occurs when using a photographic flash very close to the camera lens in ambient low light. The red-eye effect is a photographic effect, not seen in nature.
Microstock photography is an offshoot of traditional stock photography. A number of microstock sites also sell vector art, and some sell Flash animations and video, as well as images. iStockphoto and stockxchange are examples of Microstock.
There are many photography blogs on the internet which offer photography tricks and tips for aspiring photographers. Apart from this, there are many video tutorials which guide amateur photographers. Even expert photographers host websites put videos and some of their best photographs. There are a few key points to be noted before taking a photograph. It is possible that more pictures are ruined by camera shake than any other reason. When a point-and-shoot picture is taken, the shutter stays open long enough to make a good exposure. Camera shake occurs while the shutter is open and exposing the film. If there is any movement, it will show up as motion lines and ghost images. This often happens in low light, with longer shutter speeds needed to expose the image. The more you zoom in, the more the camera will shake. So getting a sharp picture with a zoom requires a much higher shutter speed than if you were using a wide-angle lens.
A photographer is a person who takes a photograph using a camera. A professional photographer uses photography to make a living whilst an amateur photographer does not earn a living and typically takes photographs for pleasure and to record an event, place or person for future enjoyment. Some of the world’s top photographers are Helmut Newton, Baron Wolman, Dorothea Longue, and Stephen Avarez. Other famous photographers include Rolf Aamot, AnSel Adams, Cris Alexander etc.
