          Assignment 1 is all about HIV/AIDS awareness poster in Africa, then connecting the poster with QRcode with the poster's detail in it 

        

         Assignment 2 is all about after effect to create typographic text and images with the music of your choice

                              

Lecture 11 & Chapter 14: Digital Video Data Sizing 

         Firstly, i learned what is data rate. Data rate is the rate at which information being transferred, it is expressed in terms of [amount of information] per [unit of time]. Example, Data rate used to describe the speed of a hard drive is Megabytes/second. For compressed audio files, kilobytes/second is used. When a data rate is determined, you can calculate the estimate amount of hard drive space needed to store the video.

      Secondly, i learned how to calculate the file size of an uncompressed digital video & converting bytes to gigabytes. Then how to calculate the file size of an uncompressed audio file.

     The formula is as follows:                                                 Raw video data size

     = frame size (width X height) * frame rate (fps) * color depth            (in bytes) * time (in seconds).

      Converting bytes to gigabytes. 

    

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)

             

      The formula is as follows: 

        8-bit mono  Second*KHz = Size

       16-bit mono (Second*KHz)*2= Size

       8-bit stereo (Second*KHz)*2= Size

       16-bit stereo ([Second*KHz]*2)*2= Size

       16-bit stereo ([Second*KHz]*2)*6= Size

    

            Finally, i also learned how to determine the factors to be            considered in graphics selection for a multimedia project. Which        are Purpose The aim which the product has been produced,             Quality Product must reach aim of the quality as specified by          the client, and Cost depend on the quality and aim. 

Lecture 10 & Chapter 13: Using Darkroom Tools

    

            Firstly, i learned how to apply the Clone Stamp tool to hide flaws. Picks pixels from one area and pastes them into a new area. Aligned source-destination relationship remains constant. Non-aligned pixels are applied anywhere. Option/Alt click to collect pixels from one location. Click in the new location to paste pixels.

              Secondly, i learned how to work with the healing brush. it use to retouch and repair areas of subtle gradations, it works like Clone stamp. Option/Alt-click to “load pixels” Click to paint pixels. The Healing Brush makes subtle changes so multiple passes are usually required. it works like clone stamp tool except that Photoshop calculates a blending of the sample pixels and painting area so that the restoration is especially subtle.

             Thirdly, i learned how to use the Patch tool to repair solid-color areas .Its used to repair large areas of solid or near-solid color. Source – repairs the selection shape & Destination – repairs the re-positioned location. Then how to analyze an image from the upper left horizontally across the image and back to the left. works like healing brush tool but instead of using brush strokes to paint from a designated area, you drag a marquee around the area to be fixed. History  brush works like clone stamp tool except that it paints pixels from a designed previous state or snapshot that you select in the history palette.

                  Finally, i learned how to softening images with Gaussian Blur. Softening is used to blur and smooth gradations to make an image appear softer Blurring averages dark and light values Gaussian Blur can also be used to prevent banding in blends

 Lecture 9 & Chapter 12: Using Windows Movie Maker

        Firstly, i learned how to be able to describe various broadcast video standards. Which are NTSC(National Television Standard Committe) consist 522 line/60Hz, & 30fps this standard is used primarily in north america, taiwan, south korea & japan. PAL(Phale Alternate Line)625 line/50Hz, & 25fps, this standard is used primarily in europe, asia and south africa, & SECAM(Systeme Electronique Couleur Arec Memoire) consist of 625 line/50Hz, & 25, this standard is used primarily in france, part of middle east, and russia.

         Secondly, i learned how to able to describe video 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. 

Lecture 8 & Chapter 11: Drawing Shapes

               Firstly, i learned how to used different type of shape tools & three different types of shapes can be created with shape tools. Which are Rectangle tool, rounded rectangular tool, ellipse tool, polygon tool, and custom shape tool. Then option to select before using the shape are clipping mask is a shape that acts like a cookie cutter, path shape is like the paths created with the pen tool, and fill shape is created with pixels.

 

            Secondly, i learned how to work with shape & what is a path layers. Paths are lines and curves that make up the outlines of vector graphics, a shape layer acts like a cut out – cutting the shape out of a layer, two thumbnails on a shape layer, the thumbnail on the left is a fill layer, which contains pixels of color, the thumbnail on the right is a vector mask, which contains a vector-based circle shape,that shape acts as a mask, and hiding all the fill layer pixels outside of the white area of the mask. You can load custom shape libraries by using the drop down menu on the options bar.

      

                         

 Lecture 7 &Chapter 9 & 10: Text

          Firstly i learned  what is type and how to create type elements. Photoshop type is made with vectors, vector is composed of line & points. Type options can be set in the Options bar, they are orientation which can be use rotate your text, font family which you can select the type of text, font style which you can select a text style, font size which you can re-size your text, font color to set color, anti-aliasing to smoothing the striking edge of a text, justification, and warp setting to create warped text which will allow you to fit text with a special design problem.

       Secondly,i learned how to control the font attributes. Which include, kerning used to adjust space between characters/alphabet, tracking to adjust space between words, vertical & horizontal scale to re-set size, leading to adjust lines in paragraph, baseline shift to adjust a character up & down, and attributes, such as superscript, subscript, all caps & bold.

 

    Thirdly, i learned how to manage the type layers & paragraph type. When type layers are linked, they can be moved as one layer, type layers can be merged or combined into one layer, flattening or merging layers containing type will rasterize the type, and rasterized type is not editable. Then it is always a good idea to save a copy of the file in PSD format to preserve all data. A paragraph is a series of words created when you start typing and ends when you press the Return/Enter key, text can be copied from another application using the clipboard, text from the clipboard can be placed in a text box in Photoshop. text box is contained within a specified region.

              Finally, i learned how to used text as a clipping mask &  Apply special type effects. A type mask can be used to add a gradient fill to text, the type mask is a selection in the shape of type that can be filled. Layer styles can be applied to type layers, layer styles can add drop shadow or bevel & emboss effects.

Lecture 6 & Chapter 8: Filters

    Firstly, i learned what is filter & how to work with filter gallery. Filter are special tools that allow you to apply special effect to your image. It can be used in several ways, like enhance images, create artwork, add lighting effects, repair damage, improve sharpness and soften harsh details. Filter menu contains: standalone filter that contain one component, primary filter groups & third party filter that has sub menu/options below to choose, and filter group sub menu. The Filter Gallery shows generic previews of the effects of each filters & options for filter effects can be found on the right side of the gallery. You can add more than one filter effect by clicking the New Filter button.

                         

Filter Sub menu                                                                                                                                                           Filter gallery menu

          Secondly, i learned how to combine application of filters with selections to create custom texture. It is a good practice to create a duplicate of a layer before applying a filter to preserve the original pixels.

           

        Finally, i learned how to used the Liquify filter. The Liquify Filter allows you to push pixels around as if they were wet paint. which are wrap turbulence, twirl, twirl, push, mirrow, ccw, pucker, bloat, pixel shift and reflect. The Mesh feature is useful when you’re trying to keep distortion relative to the objects in the original image. The Freeze Mask protects portions of an image from distortion. 

Lecturer 5 & Chapter  6 & 7: Working with Layers and Layer Styles

     Firstly, i learned recognize elements of the Layers palette, such as new layer an option to create a layer, delete layer an option to delete a layer, adjustment layer, layer mask an option to protect layer,layer effect an option to add special effect to the layer, text layer an option to write a text on an image, layer opacity an option to reduce the color range of an image, link layers an option to connect two or more layers as one, layer visibility an option to hide or display a layer, blending mode an option to add different style to an image, lock: transparency, pixels, and position

   

                                  

          Secondly, i learned how to identify and explain 5 different types of layers, which are normal layer that are added on a current layer, adjustment layer that are use to modify an image without affecting the original pixels, layer mask that are used to protect a layer, shape layer that contain vector shape, and type layer that contain text element. 

         

        Thirdly, i learned how to merge and flatten layers, we merge two or more layers in other to make them as one.

While flattening layers merge all layers in a document with the purpose of optimizing/maximizing the file size. merge layers command will merge the link layers in the image.

          

                                            

        Finally, i learned how to apply layer style onto layers will add special effect to and image. Several options are available for different layers, like bevel & emboss, stroke, inner shadow, drop shadow, inner glow, outer glow, gradient overlay, color overlay, pattern overlay, and satin.

Lecture 4 & Chapter 4 & 5: Making and Manipulating  Selections 

         

      Firstly, i learned what is selection tools? they are used to specify area of editing an image, such as color changes or replacing a sky. then how to create elliptical and rectangular selections using rectangular marquee tools, elliptical marquee tools, single row marquee tools, and single column marquee tools. There are four option that you can choose one before going to selections also called select behaviors. Which are new selection, add to selection, subtract from selection and intersect with the selection.

           
  

       Secondly, i learn how to identify the specific function of various lasso tools. There are three types lasso tools, which are polygonal  lasso tools create a straight slide selections around object by clicking the object edge, magnetic lasso tools tracks the edges of an object based on shifts in color or tone, and lasso tools create selections on freehand tracking. 

              

        

      Thirdly i learned about anti-aliasing and feathering. Anti-aliasing makes the edge of an image with striking/scratch looks smooth, while feathering makes an image looks blurred or soften. I also learned several transformations that are available for selections, using scale, rotate, skew/distort, perspective, and flipping-turns. I also learned several shortcut for selections.

        Feathering

      Finally, i learned save and loading selection. You can choose select > save selection to save a selection and selections are saved as alpha channels.

•Channels also contain specific image data:

§Black and White images contain one color channel

§An RGB image contains 4 color channels

§A CMYK image contains 5 color channels

Lecture 3 & Chapter 3: Painting and Drawing with Color 

            Firstly i learned how to work with the Brushes palette, they are certain options available settings that control how the painting tools interact with the image. Such as brush tools, an option where you will choose the kind of brush you want to use, brush palette where you can choose your brush behaviors, size and color.

      Secondly, i learned how to use the Painting tools. Such as, brush tool which are use to add color or retouch area of an image, gradient tools are smooth transitions between two or more colors, history brush & art history brush tool,which make it easy view out work and undo it with a previous actions, and color replacement tool which are used to change the color of a particular area in an image. 

                   

                       

           Thirdly, i learned how to create blend between different colors. Blending modes affect how paint interacts with the pixels underneath the painted area. Then opacity affects the transparency of the color, pattern, or effect.

                  

                           

      

           Finally in this chapter i learned to use the eraser tools, eraser paint in three ways. Which are background layer that paint with background color, normal layer that erase all data and make the area transparent, and eraser history to history or (history brush) that used previous version to undo commands. And there are also special types of erasers, which are background eraser tools it delete background pixel of a layer, and magic eraser tools delete pixels of the same color at the area that was clicked.
