Light and the Lens: Key to processing and capturing and image (image plane)

Lens are curved glass elements that bend light and focus an upside down reflection onto a light sensitive surface or image plane

Image plane: Film or a computer chip (CCD, CMOS)

The Window of the Camera

Key Terms

Focal Length: Center of the glass element (lens) to the image plane

Lens characteristics: Wide Angle - Short focal length-wide field of view

Normal – Similar to the eye

Telephoto – Narrow field of view – long focal length

Characteristics - Technical

Wide angel lens – Barrel distortion – increases depth perception, minimizes shake

Telephoto lens – Compress depth – Softens image – exaggerates camera shake

Aperture - Movable blades control lightIris = pupil

Aperture - Diameter of the opening

Measurement - f-stops

Technical (con’t) Shutter Speed - The time the each frame of video is exposed to light

Shutter – Allows light to enter the lens and expose the light sensitive material on the image plane (length of time)

Fast shutter speed - freezes action, slow - blur image

Aperture and shutter speed produce an image

It Must Look Right Focus – Adjusting the lens elements to the position that allows the reflected light to converge, creating a sharply defined image.

Depth of Field - Area that the image appears to be in focus

Shallow Focus – Directs the viewers attention to what is sharp

Deep Focus – Allows the viewer to choose what to look at

Three variables for depth of field – Aperture, camera/subject distance/focal length p.58

It Must Look Right Resolution – Clarity of the image

Analog vs Digital – Generational loss (analog) – Sampling - Reproduction without noise

SLR- Pro camera (Single-Lens Reflex)

Digital – CCD or CMOS sensorsPixels (picture elements) electronic signal that becomes a digital representation of the image

Resolution Pixels=detail in the image5184x3456 (18 megapixel) -720x480 low quality

Compression – Digital Video

Compression – Reduces the file by discarding redundant info

Digital Video – Digital TV doesn’t equal HD

Analog TVs require a digital converter

Digital video can be SD or HD

Resolution 1280x720 1920X1080 Interlaced: Two fields –odd and even are scanned (1080i)

Progressive: Each line is scanned in order (top to bottom 720p or 1080p) p.72
