Chapter 13 : Digital Video Data Sizing

Data Rate
- is the rate where information being transferred
- per unit time

Calculating file size of an uncompressed digital file

Raw video data size
= frame size (width X height) * frame rate (fps) * colour depth (in bytes) * time (in seconds)


8 bits = 1 byte
1 kilo(bit/byte) = 1,024 (bits/bytes)
1 Mega(bit/byte) = 1,048,576 (bits/bytes)
1 Giga(bit/byte) = 1,073,741,824 (bits/bytes)


Factors to consider when selecting graphics to be used in a multimedia project:

- purpose 
- cost 
- quality 

Chapter 12 : Broadcast Video Standards

Broadcast Video Standard
NTSC (National Television Standards Committee)
  - 525 lines/60Hz
  - This standard is used primarily in North America, Taiwan, South, Korea, Japan.
  - 30 fps
PAL (Phase Alternate Line)
  - 625 lines/50Hz
  - This standard is used primarily in Europe, Asia, and Southern Africa.
  - 25 fps
SECAM (Systeme Electronique Couleur Avec Memoire)
  - 625 lines/50Hz
  - This standard is used primarily in France, parts of Middle East, and Russia.
  - 25 fps


Aspect Ratio

• The aspect ratio of a frame describes the ratio of its width to its height in the dimensions of a frame
• For example, the frame aspect ratio of NTSC or PAL video is 4:3, whereas DVD, HDTV, and motion-picture         frame sizes use the more elongated aspect ratio of 16:9 



Chapter 11 : Drawing Shapes

Shapes
- clipping mask : act like a cookie cutter
- path shape : path created with pen tool
- fill shape : created with pixels

Shape Layer
- two thumbnails on shape layer
- left thumbnail contains pixel of colors (fill layer)
- right thumbnail contains vector based circle shape (vector mask)
- the shape act as mask, hiding all the fill layer pixels outside white area of the mask


Chapter 9 & 10 : Text

Type
- it is vector image

Type of attribute
- tracking                     - leading
- kerning                      - vertical / horizontalscale
- baseline shift             - attributes

Paragraph Type 
- A paragraph is a series of word created when you start typing and ends when you press enter key.

 Clipping Mask
- used to add gradient fill to the text.

Applying Style
- can add or drop shadow , bevel and emboss effects.

Chapter 6 & 7: Working with Layers and Layer Styles


Layer
- A layer is any image on a transport background which is stack of another.
- Combination of several layer called merging.

Functions
- create composite image                - add special effects
-create complex projects                 - repair photos
- correct colour 

Types of Layer
- Normal layer : added on top of current layer
- Adjustment layer :modify an image without destroying the pixels
- Layer mask : protect area of layer
- Shape layer : contains vector images
- Type layer : contains text

Merge & Flatten Layers
- Merging : combining two or more layers
- Flattening : combining all layers in one file to optimize the file size
- Linking : connecting layers together (layers move together)

Layer Style
- adding special effects to the layer

Chapter 4 & 5: Making and Manipulating Selections

Selection Tool

- enabling yourself to only paint in one area while the rest of your canvas is left unaffected.


Aliasing



Feathering 

- softening edges of image

Lasso tool

- Polygonal Lasso Tool : it allows us easily draw free form selection outlines based on straight sided                                            polygonal shapes.
- Magnetic Lasso Tool : tracks the edges of an object based on colour tone
- Lasso Tool : free hand tracing for selection

Transforming Selection
- scale    -rotate   -skew   -perspective   -flipping




Chapter 3: Painting and Drawing with Colour


Working with the Brushes Palette

  • control how the painting tools interact with the image.
  • to customize and create brush in many ways


Painting Tools
  • add colour and retouch images 
  • works only on bitmap images which means image that has pixels


Creating Gradient
  • 5 option of gradient
  • there are a few preset gradient available in option bar



Eraser Tool

      -  2 type of eraser : Background eraser => delete pixels of background layer                                                       Magic eraser => delete the area that clicked which is same colour





Chapter 2: Viewing and Managing Documents

Colour modes

- colour mode = colour spcae / colour model
- visible spectrum = colours that can be seen by human eyes
- gamut = produce by device



History palette
- undo multiple commands
- it has list of recently executed commands

Changing on screen size of an image 
- click Image > Image size

Chapter 1 : A Quick Tour of Adobe Photoshop


 Opening and Saving Images


 How to open and save image
 ~To open: File => Open

 ~To save: File => Save


  File Formats
  ~preserve layers 

File formatUses
PSD (Photoshop Document)Used for Photoshop document
PDF (Portable Document Format)Used for portable document
PSB(Large document format)Used for large document
TIFF(Tagged image file format)Used for Printing

~does not preserve layers 

File FormatUses
GIF , JPGWeb Graphics
RAWFor Digital cameras

Pixel
Physical point in a raster image, or the smallest addressable element in an all points addressable display device.
  1 bit = 2 colours
*   4 bits = 16 colours
*   8 bits = 256 colours
*   16 bits = 65,536 colours
*    24 bits = over 16 million colours

Relationship between resolution, on screen size and print size 
 
on screen size / resolution = printed width

resolution = 300 pixels per inch for printing
                 = 72 pixels per inch for display
