More outline for week 8,

Type tools


Perspective cloning l.jpg
Perspective Cloning

  • Open cschallway.psd.

  • Filter -> Vanishing Point.

  • Create and Adjust a blue Plane Tool up the hallway floor.

  • The Stamp Tool clones according to the perspective.

  • Try cloning a wide tile boundary up the hallway center.


Type tools l.jpg
Type Tools

  • Horizontal and Vertical Type

    • Download Type.zip from Parsons/Inbox.

    • Open ScottsRunKayak.jpg in Photoshop.

  • Adding horizontal or vertical type creates a new layer.

  • Click a point on the Background for Point Type.

  • Click and drag for Paragraph type.

    • Add some of each, set against Background Layer.

    • Set color in Type Options palette.

  • Font, Point Size, etc. similar to word processing.


  • Type is vector graphics l.jpg
    Type is Vector Graphics

    • Image pixel-based graphics so far constitute raster graphics, a.k.a. bitmapped graphics.

    • Raster graphics are defined in terms of a 2D matrix of pixels displayed on a raster.

    • Vector graphics are description of objects to draw using lines, stokes, etc.

    • A vector can be rendered at any resolution. Only when rendered does it appear as pixels.


    Rendering vector graphics l.jpg
    Rendering Vector Graphics

    • Font, Point Size, Text Style, Anti-Aliasing Parameters describe the vectors and vector rendering of type.

    • Zoom in on selected text and try anti-aliasing parameters None - Smooth, also zoom out.

    • The rendering process computes pixels.

    • Older generation vector graphics displays actually displayed vectors via electron beams.


    Re editing text l.jpg
    Re-Editing Text

    • Select the text while in the Type Tool.

    • Paragraphs can be resized and rotated.

    • Control-clicking the Layer allows conversion between Point and Paragraph Type.

    • Text can be pasted into the Type Tool from another application.

    • Text can be imported from Adobe Illustrator.

      • We will start working with Illustrator soon.


    Transforming text l.jpg
    Transforming Text

    • Type tools allows parameter based changes.

    • Move Tool with Show Transform controls checked allows you to transform text area.

    • Bring up Window -> Character palette.

    • Slide or adjust kerning for between-character spacing.

    • Slide or adjust tracking for multi-character spacing.


    Character formatting l.jpg
    Character Formatting

    • Character Palette applied to a paragraph allows leading (inter-line spacing) adjustment and horizontal scaling adjustment.

    • Other options at bottom of Character Palette allow additional formatting of character appearance. Baseline shifts bottom of text.

    • Type Option Palette supports changing orientation, alignment, text warping.


    Paragraph palette l.jpg
    Paragraph Palette

    • Delete Type layers then create a new Paragraph Type layer.

    • Window -> Paragraph Palette.

    • Alignment based on whole words, hyphenated syllables or entire line of text.

    • Give margins and indents in points, inches or centimeters. They convert to points.


    Layer effects for type l.jpg
    Layer Effects for Type

    • Open a clean copy of ScottsRunKayak.

    • Place a large-font, fat, neutral color text saying “Type” over a dark area.

    • On layers palette click the fx (Effects) icon.

    • Add Bevel and Emboss initially, experiment visually with their effects on text.

    • Add other effects via checkboxes, then adjust their parameters.


    Layers styles l.jpg
    Layers Styles

    • Get a Type layer effect that you like.

    • Window -> Styles.

    • Save the Style that you just created.

    • Try other Styles from the library.

    • Pattern Overlay is good for text.


    Rasterizing text l.jpg
    Rasterizing Text

    • To apply bitmap (raster) pixel transformations to a Type layer you must Rasterize it.

    • At that point you can no longer manipulate it as editable type. It has become an image.

    • Control-click and Rasterize the layer.

    • Get type to the image that you want to combine before rasterizing it (if at all).

    • Try out Filter gallery -> Sketch Filters on text.


    Screening back type l.jpg
    Screening back type

    • Close All, Open ParsonOffice.jpg.

    • Add a layer of big, black, bold text type.

    • Apple-Click the T icon in the Layers Palette to select the text’s pixels.

    • Shut off the text layer’s eyeball.

    • Create a Levels Adjustment Layer.

    • Trash the text layer.

    • Adjust Levels to screen the text back in.


    Reusing type derived layer mask l.jpg
    Reusing type-derived layer mask

    • Once you have the layer mask, you can duplicate the layer.

    • You can unlink the layer mask from the duplicate layer.

    • You can add another adjustment layer.

    • You can move a layer mask copy into it.

    • You can copy-move a layer mask to a Smart Filter layer as well.


    Hacking text l.jpg
    Hacking Text

    • Use some novel, fat fonts.

    • Create some fresh rasterized text.

    • Use Selection and Move tools to tear it apart and put it back together again.

    • Use vector-generated font graphics as visual building blocks.


    Assignment 6 l.jpg
    Assignment 6

    • Create a Folder called Type. This is the last assignment to focus on Photoshop mechanics.

    • Use your own photographic images. Bring them to class on November 2.

    • This assignment requires one completed image. It focuses on the Type Tool integrated into an image.

    • On November 2 we are also going to discuss aesthetics, and brainstorm about a final project in Photoshop. Bring some ideas to class.


    Assignment 6 type l.jpg
    Assignment 6 – Type

    • Do something creative with Type Tool that integrates type into an image. Use your imagination.

    • Make a poster, an advertisement, a flyer, or integrate some poetry into an image.

    • This one is due on November 11 as Type.zip.

    • I will look for at least 4 substantial type transforms, for example level effects and post-rasterization transforms. Make sure to include your log file description of these steps.
