Science of Photography

The Science of Photography refers to the areas of science, such as chemistry and physics, that makes photography possible. The mechanics of a camera, the dynamics of the shot and the chemical development of the film must be properly balanced and played out for the photographer to be able to take and develop his pictures. In fact, at every stage of the process of photography, some aspect of science is necessary to carry the process along to the next stage.

Before the photographer takes his shot, he must compose, or set up, the scene. Lighting, lens aperture, shutter speed, focal length and the angle of the shot are all part of the science of setting up the shot. If there is insufficient lighting or the shutter speed and the film speed aren’t aligned, then the resulting shot may be underexposed or blurry.

Taking photos of the show on stage

Taking photos of the show on stage is a unique branch of photography. Knowledge of photography is not enough to do lunch. In addition to need the experience of shooting-shooting earlier, stage photography also need "local experience".

Local experience in question is the understanding of the scenes that will be photographed. In a theater for example, a photographer needs to get a "key scenes", which is a photograph that could represent the overall performance. Here, time or when the camera take a shot is crucial. Two scenes are disputing a second time could be very different appearance.

Cave explorer

Photographing in the caves must be completely dry by hand. Tripod became obligatory to always be there, could also use a table or stool hard, but it's certainly difficult to enter the cave take the table. Using the manual mode is standard, but with knowledge of the standard specification manual cameras used logic can be run again. Tool of the additional lighting besides the flash and boom is needed. Then the tape measure or rope with the right size (5 feet, 3 meters and 1 meter).
Once we find an object, determine exactly where the camera position will be to take the image composition. Attach a sturdy tripod and make sure it is. Do not shake or unbalanced.

Tilt Shift Lens Not Just For Architecture Photos

I want to try to explore and prove that the tilt-shift is not just for architectural photos just using a large format camera but a 35mm SLR or DSLR users can also use it for images other than photos of architecture. Possible for professional photographers already using the camera view to foto2 their product is not new anymore, but the camera view once its use is very limited (ie in the studio only). they do not mind carrying a camera view for the photo session at the site. And limited funds that made me choose a lens which I will use in this article.

Scheimpflug principle

The Scheimpflug principle is a geometric rule that describes the orientation of the plane of focus of an optical system (such as a camera) when the lens plane is not parallel to the image plane. It is commonly applied to the use of camera movements on a view camera. It is also the principle used in corneal pachymetry, the mapping of corneal topography, done prior to refractive eye surgery such as LASIK, and used for early detection of keratoconus. The principle is named after Austrian army Captain Theodor Scheimpflug, who used it in devising a systematic method and apparatus for correcting perspective distortion in aerial photographs.

Objects with blue sky background

When shooting outdoors, sometimes we are tempted to take pictures of people / objects with blue sky background (bright). Usually these conditions can be obtained during the day (over 10 hours). However, usually the desired results are not as expected, for example, objects in the image into a silhouette or the background to white sky (over).
 
This happens because we are fooled by lightmeter difficult lighting conditions, the background is too bright (bright blue sky) while the object is darker than the sky background. So when we do the metering into the sky had become the object silhouette, whereas when we do the metering to the object, the sky becomes white.


These conditions can be overcome by the use of flash. The goal is that the object and background clearly visible (not over or silhouette). Here are the steps shooting:

Marco Polo - A Photographer’s Journey

Marco Polo, the name is certainly not foreign to our ears, whether it's a brand name or the name of the person. The name of this one has its own charm until we can find it everywhere. Although many people have heard this name, few people really know who Marco Polo, the history and origins. I am among those who do not understand this will figure Marco Polo. I only know the Marco Polo as an explorer and trader of European nationals who have an impressive adventure stories.

Wedding photography

Wedding photography is the photography of activities relating to weddings. It encompasses photographs of the couple before marriage (for announcements, portrait displays, or thank you cards) as well as coverage of the wedding and reception (sometimes referred to as the wedding breakfast in non-US countries). It is a major commercial endeavor that supports the bulk of the efforts for many photography studios or independent photographers.

Like the technology of photography itself, the practice of wedding photography has evolved and grown since the invention of the photographic art form in 1826 by Joseph Nicéphore Niépce.In fact, an early photograph, recorded some 14 years after the fact, may be a recreation for the camera of the 1840 wedding of Queen Victoria to Prince Albert. However, in the early days of photography, most couples of more humble means did not hire a photographer to record the actual wedding itself.

Tripod

In photography, a tripod is used to stabilize and elevate a camera, or to support flashes or other photographic equipment. All photographic tripods have three legs and a mounting head to couple with a camera. The mounting head usually includes a 1/4" diameter, 20 threads per inch (1/4-20) thumbscrew which couples to a female receptor located on the vast majority of cameras, as well as a mechanism to be able to rotate and tilt the camera when it is mounted on the tripod. Tripod legs are usually collapsible towards the height axis and telescoping, in order to save space when not in use. Tripods are usually made from aluminum, carbon fiber, steel, wood or plastic.

Halloween photo

Get camera viewfinder straight in front of the model and props. Make sure the
sun is behind you. The best time to shoot is before 10am and after 4pm when the
sun is not so harsh. There you are a great Halloween picture. Buy a large
pumpkin and some hay. Set the hay in your yard where you can see tree
scenery behind where your model will be sitting on the hay bale. Position the
pumpkin on the ground at the left or right side of the hay bale. Take a couple of
shots.
There are plenty of subjects around to photograph at Halloween ranging from the traditional jack-o-lantern through to people in costume, to trick or treat ‘treats’ etc. It’s a time of color, emotion and lots of interesting subjects.

Autofocus modes

Autofocus modes – autofocus can either activate until a lock is found (single, AF-S) or be continuously active (continuous, AF-C, servo). Single mode is especially used for stationary subjects, when focus, once found, should stay fixed, while continuous mode is instead used for moving subjects. Some AF systems also include anticipation of position of moving subjects – Canon calls this "AI servo" (for "artificial intelligence") – or can automatically switch between single and continuous depending on whether the subject is moving – Canon calls this "AI focus".

Infrared photography

In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Usually an "infrared filter" is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red).

Digital Single-Lens Reflex (DSLR)

This camera is named for the reflexing mirror that allows you to frame the image
through the lens prior to capturing the image. As light passes through the DSLR
camera’s lens, it falls onto a reflexing mirror and then passes through a prism to the
viewfinder. The viewfinder image corresponds to the actual image area. When the
picture is taken, the mirror reflexes, or moves up and out of the way, allowing the open
shutter to expose the digital image sensor, which captures the image. Most features on
a DSLR are adjustable, allowing for greater control over the captured image.
