ARTS 6THIRD GRADING PERIODBy: Ric Angelo Dagdagan

Screen printing is a printing technique whereby a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil. A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed.

Basically, it is the process of using a mesh-based stencil to apply ink onto a substrate, whether it be T-shirts, posters, stickers, vinyl, wood, or other material.

PHOTOGRAPHY

WHAT IS PHOTOGRAPHY?• Historically the word Photography is derived from the greek words

"photos" (meaning "light") and "graphein" ("to draw"). It was used by scientists to describe a method of recording images by the action of light, or related radiation, on a sensitive material.• 'the art and science of capturing the image of a certain event in time and recording it in a film or a digital medium using a camera.'

PARTS OF THE CAMERA

TYPES OF CAMERA

FILMED AND DIGITAL CAMERAS

CLASSIFICATION OF CAMERA• Compact Cameras or Point-and-Shoot cameras are those cameras

that allow you to do just that -- "Point" and "Shoot". • Traditional compact cameras use a simple window through the body of

the camera as a viewfinder.

• Cameras that belong to this classification may range from more advanced compact cameras to SLR-like super zooms and Bridge Cameras. The differences between these and Compact cameras are: Sub-Compact cameras can be used with Automatic, Semi-manual, or Fully Manual settings; they may have a bit larger bodies and usually larger sensors and larger lenses; they generally have longer zoom ranges; and obviously a bit heavier.

CLASSIFICATION OF CAMERA

• Single Lens Reflex cameras use only one main lens set. The image from this lens is delivered to the viewfinder through a set of mirrors and / or prisms working like a periscope. When the shutter button is pressed, the mirror momentarily closes to allow the image to go from the lens directly to the imaging chip. This way, the viewfinder will show the user to the actual image as it

CLASSIFICATION OF CAMERA

• Rangefinder Cameras are another category of cameras that are fitted with a rangefinders to determine the distance of an object. Traditional rangefinders display two images of the same object in the viewfinder, one each from two different opening in the Camera. The distance of the focused object is determined by adjusting a focusing ring and making these two images align. This distance is then transmitted to the lens to obtain a proper focus on the subject.

CLASSIFICATION OF CAMERA

APERTUDE• A camera’s aperture setting controls the area over which light can pass

through your camera lens. It is specified in terms an f-stop value, which can at times be counter intuitive  because the area of the opening increases as the f-stop decreases. In photographer slang, when someone says they are “stopping down” or “opening up” their lens, they are referring to increasing and decreasing the f-stop value, respectively.

SHUTTER• A camera’s shutter determines when the camera sensor will be open or

closed to incoming light from the camera lens. The shutter speed specifically refers to how long this light is permitted to enter the camera. “Shutter speed” and “exposure time” refer to the same concept, where a faster shutter speed means a shorter exposure time.Shutter speed’s influence on exposure is perhaps the simplest of the three camera settings: it correlates exactly 1:1 with the amount of light entering the camera. For example, when the exposure time doubles the amount of light entering the camera doubles. It’s also the setting that has the widest range of possibilities.

ISO SPEED• The ISO speed determines how sensitive the camera is to incoming light.

Similar to shutter speed, it also correlates 1:1 with how much the exposure increases or decreases. However, unlike aperture and shutter speed, a lower ISO speed is almost always desirable, since higher ISO speeds dramatically increase image noise. As a result, ISO speed is usually only increased from its minimum value if the desired aperture and shutter speed aren’t otherwise obtainable.

EXPOSURE• When these three elements are combined, they represent a given

exposure value (EV) for a given setting. Any change in any one of the three elements will have a measurable and specific impact on how the remaining two elements react to expose the film frame or image sensor and how the image ultimately looks.
