Lectures

Week 1 

Mr. Martin, (who also happens to be some of our FLAME mentor) introduced himself and briefed us on the assessment criteria on the MIB. He also gave a brief history on imaging, and walked us through Project 1. We were also recommended certain materials for our module (worth investing in a simple tripod).

PEN TOOL & PHOTOSHOP
1) Bezier Game: This was a little task for us to practice using the pen tool better.

Fig 1.1: Beziér Game Result

2) Create your E-Portfolio (if not already made)

3) Register Pinterest: 

4) List down your 3 favourite graphic design work from Pinterest and explain why you like the designs.

Design 1

Fig 1.2: Design 1 by @syrushahidi 

DESCRIPTION:
This work caught my eye because of its futuristic ambience and surrealism. Despite the obvious surrealist premise of the image, I like how seamlessly the elements fit together. I quite like the balanced use of space in this piece as it helps add depth and dimension to the environment. The blue hues in this composition express an almost monotonous, somber mood which I think compliments the social isolation and detachment that is not only prevalent in today’s societies, but projected to increase in the future.

Design 2

Fig 1.3: Design 2 by Xi Huang

DESCRIPTION:
Slightly distorted portraits like these are some of my favourite styles of photos. I think one of the strengths of this image is its simplicity. Though in the grayscale, there is good use of contrast that draws the viewer in to the photo. I like how the slight graininess that achieves an almost vintage film-like feel. The subtle overlay is quite beautiful as well. Overall, the skillful use of balance, contrast and alignment make for a very pleasing composition.

Design 3

Fig 1.4: Design 3 by Charlie Davoli 

DESCRIPTION:
I was drawn to this image because of how cinematic it is. This picture feels like a window into a fantastical world; the kind that adventure/ sci-fi/ fantasy novels evoke in the imagination. The softness of the image also makes for an ethereal, magic look. To actually tangibly see a scene like this with all its details is quite cool, instead of the vague blurry vision formed in one’s imagination. 

Week 2 

Intro to Basic Composition
Composition is fundamental to good design. It is the way in which all the elements come together to form a whole/cohesive design.

Ask yourself when browsing pictures on Pinterest (or wherever) "how does it work?" 
i.e. "how does the composition work in its favour?"


ELEMENTS OF A GOOD COMPOSITION

1. Focal Point
  • "Where do your eyes naturally settle on first?"
  • A strong focal point helps direct viewers' attention to the most important pieces of your design.

2. Scale & Hierarchy
  • Scale is often used to communicate hierarchy (i.e. by directing eye towards or away from certain elements to signify importance to the communication)
  • Larger elements attract more attention (they have more visual weight)
  • Hierarchy - order of information from most important to least
  • Eye contact is a strong drawing point because of the natural reaction of humans to gravitate towards eyes (evolutionary).

3. Balancing the Elements
  • All elements have visual weight
  • Larger elements --> more visual weight
  • Arrange elements so that they complement each other in the design i.e balance weighted elements until an effective equilibrium is reach

4. White Space/Negative Space

Fig. 2.1: An example of good and bad use of white space
  • A support element for boosted clarity
  • Balances out main focus of a composition
  • Helps design to 'breathe'

THE RULE OF THIRDS

Fig. 2.2: Distribution of attention to each intersection point

  • The four intersection points created - best for focal points
  • Basically a guideline
  • From the 4 intersection points, some have a higher % of attracting the viewers' attention
  • A finding - based on western culture; reading from left to right, top to bottom.
  • A majority of the global population is influenced by western culture through western media. (a possible repercussion of colonialism?)

THE GOLDEN RATIO

Fig. 2.3: The Golden Ratio in works of Design

  • A mathematical ratio 
  • Very commonly found in nature
  • Generally pleasing to the eye because it fosters organic and natural-looking compositions

Week 3 

Intro to Photoshop 2

Today's lecture involved a more hands-on approach of learning where Mr.Martin tasked us with navigating Photoshop alongside his demonstration of using different selection tools.

LASSO TOOL, PEN TOOL & LAYERING

We were all provided a set of images (shown in figure X) that were to be photoshopped onto a living space. Each table required us to use different selection tools depending on best suitability.

1. Lasso Tool: 
  • Freehand selection 
  • Similar to pen tool
  • Hard to follow contours
  • Not very practical

2. Polygonal Lasso:
  • For straight lines
  • More precise!
  • Use [DLT] to undo (not [CMD] Z)

3. Magnetic Lasso:
  • Automatically follows contours (as detected by Photoshop)
  • Press [SHIFT] to add to selection
  • Press [option] to subtract from selection

4. Pen Tool:
  • Good for organic lines
  • Can create extremely precise shapes + paths (by manual placement of anchor points)
  • Click [option] to change direction of handles

5. Magic Wand:
  • Can select objects in clean backgrounds
  • Invert selection - [CMD] I

6. Quick Selection Tool:
  • Convenient selection tool with brush-like quality.
  • Adjustable 'brush' sizes
  • Press [SHIFT] to add to selection
  • Press [option] to subtract from selection

Week 4 

Intro to Photoshop 3

ADJUSTMENT LAYER & FILTERS

Fig 4.1: Adjustment layers can easily be edited and discarded 

The adjustment layers are a group of non-destructive image editing tools that add colour and tonal adjustments to your image.

You can edit and discard them or restore your original image at any time.
Fig 4.2: How to modify adjustment layers

SOME TYPES OF ADJUSTMENT LAYERS:
1. Brightness/Contrast

Fig 4.3: before/after brightness/contrast adjustments
  • Makes adjustments to tonal range
  • Brightness: adjusts highlights
  • Contrast: adjust shadows

2. Level

Fig 4.4: before/after level adjustments
    • Modifies tonal values (shadows, midtones, highlights)

    3. Curves
    Fig 4.5: before/after curve adjustments
      • Adjust points throughout entire tonal range

      4. Exposure
      Fig 4.6: before/after exposure adjustments
        • Exposure: highlights
        • Offset: midtones
        • Gamma: dark tones

        5. Selective Colour

        Fig 4.7: before/after selective colour adjustments
          • Selectively modifies the amount of one primary colour without affecting the rest

          W4 Practical
          VITAL TOOLS
          This exercise was meant for us to practice matching lighting and use adjustment layers + filters.

          In the demo video we watched, the pen tool was used to make the selection of the person and remove the background. However Mr.Martin mentioned that a quicker way of achieving the same result would to be to use the quick-selection tool.

          Fig 4.8: Going to the 'select & mask' tab after making selection

          Fig 4.9: Fixing selection errors using the brush tool 

          Fig 4.10: Using the refine brush tool to define hair strands + eyelashes

          After completing selection, refinements we set the output to either 'layer mask' or 'new layer with layer mask'.

          Fig 4.11: Setting the appropriate selection output

          Afterwards we can make further refinements to the selection and fix errors by selecting the clipping mask and then using the brush tool on the problem areas.


          Fig 4.12: Fixing more selection errors

          Make sure the clipping mask layer is selected before brushing.

          Fig 4.13: select clipping mask

          Note: the white region indicates the selection, and the black region indicates what's not visible. There make sure to use white to add selection area, and black to remove.

          Fig 4.14: Choose black or white depending on whether you're removing or adding to selection

          We then go to adjustment layer > solid colour, and set a background colour.

          Fig 4.15: Creating a solid colour background

          Fig 4.16: Selecting a bg colour of choice

          We then create a curves adjustment layer above our image and make it a clipping mask. This ensures that the changes we make translate only to the image it is clipped to. 

          Fig 4.17: Adjusting Curves layer

          Adjust the curves so that it creates an 's'. and voila, you're done!

          Week 5 

          Double Exposure & Image Blending Mode

          DOUBLE EXPOSURE PHOTOGRAPHY
          This refers to merging multiple images, with the goal of making something surreal, emotional or humorous. They usually feature silhouettes.

          Unlike past times, we can now utilise Photoshop to replicate double exposure effects through editing.


          SOME TECHNIQUES:
          1. Using the Tilt-Shift Effect

          Fig 5.1: Tilt-Shift Effect Example

          This tool softens your work. Try blurring one photo instead of the entire image. Go to Filter > Blur Gallery > Tilt-Shift

          2. Create Fake Reflection
           
          Fig 5.2: Fake reflection example

          In this example, the raindrops and bokeh add interesting textures to a multiple exposure photography.

          3. Combining Simple Portraits & Detailed Textures

          Fig 5.3: Example of simple portrait+textured details

          This helps give a balanced result.

          4. Converting Results to B&W

          Fig 5.4: Black & white double exposure example

          A lack of colour can strengthen emotions, evoke a sense of vulnerability, and provide unique depth to the result.

          5. Work with Silhouette

          Fig 5.5: Silhouette double exposure example

          Quite a doable way to experiment creatively.

          6. Pick Two Random Photos

          Fig 5.6: Result of two random photos

          A random process don't make the results void of meaning. They can create interesting stories for audiences to interpret. Experiment shooting interesting textures, shapes, and form.

          7. Make Simple Objects Look Fascinating

          Fig 5.7: A dull-building with a starry sky

          Turning everyday objects into something interesting can help enhance your imagination.

          8. Use Shadow

          Fig 5.8: Shadows used for double exposure

          Outlines in general are fascinating to work with for double exposure. This makes shadows just as effective as silhouettes in creating stories.

          BLEND MODES:
          These are extremely experimental because outcomes are often unpredictable! 

          Fig 5.9: Blend Modes Map

          An example of using a blend mode is as follows:

          Fig. 5.10: Red smoke to be integrated into image on left

          Fig 5.11: After using Screen blending mode on smoke

          Week 9 

          Digital Surrealism

          REALISM VS SURREALISM
          Realism: 

          Fig 6.1: Real Still-Life

          • Subject matter is what's commonly considered ordinary and part of reality 
          • Captures reality as it appears 
          • No out-of-the-box thinking

          Surrealism: 

          Fig 6.2: Surreal Still-Life

          • Twist on realism with bizarre juxtapositions
          • Explores the subconscious mind
          • Is a distortion of the ordinary and of reality
          • Dream-like in nature; defies logic

          SURREALISM & DADAISM
          Dadaism: An anti war art movement with art works that is satirical and nonsensical in nature.

          Fig 6.3: The Persistence of Memory by Salvador Dali 

          Surrealism was fuelled by Dada artists. Surrealists like Salvador Dali promoted dreamlike imagery and free association.

          DIGITAL SURREALISM 
          Photoshop makes it more accessible now more than ever to explore personal artistic expressions.


          W9 Practical
          BLENDING MODES
          This week we experimented with blending modes from 3 subsections: namely screen, multiply, and soft light.

          Put simply:
          • Screen: black = transparent, white = opaque
          • Multiply: black = opaque, white= transparent
          • Softlight: black= darker, white= brighter, grey (50%)= transparent
          EXERCISES:
          We were provided with a set of images for this practical:

          Week 10 

          Intro to After Effects (AE)

          WHAT IS AE?
          It is an animation software used for animating, visual effects and motion picture compositing. AE allows you to easily manipulate imagery by combining layers of video + images into the same scene. 

          COMPOSITING IN PHOTOSHOP
          Photoshop allows you to composite your layers. Arrange and rename them accordingly so they can be easily animated when transferred to AE 

          COMPOSITING IN AFTER EFFECTS
          Layer elements can be imported from external softwares such as Photoshop & Illustrator. They should be organised and synced on them, as AE directly links to it. 

          W10 Practical

          ANIMATING ON AFTER EFFECTS
          We are provided with a photoshop composite as shown below, and instructed to import it into AE.

          Week 11 

          W11 Practical

          ANIMATING ON PHOTOSHOP
          We did 3 exercises for this practical, 2 on Video Timeline, and 1 on Frame by Frame.

          Part 1: Removing the subject from the background
          This is done since they will be animated separately.

          step 1: use quick selection to mask the subject (Yowa). Then load selection onto the background layer by pressing [cmd] + [clicking mask of Yowa]. 

          step 2: Since the selection around the subject is quite tight, expand selection by 5px.
          Select>Modify>Expand

          Fig 8.1: loading selection onto bg and expanding selection 

          step 3:
           To make Yowa disappear,  go to Edit>Fill and select Content Aware.

          step 4: Use the healing brush tool [ J ] to spot heal mistakes/residue of Yowa to reveal clean background.

          Fig 8.2: Using content aware to remove Yowa from the background

          Fig 8.3: Clean background revealed!
          step 5: Convert Yowa and the background each to Smart Objects*, to allow for warping and transforming. 

          Fig 8.4: Convert to Smart Object

          *Smart objects also allows to make changes and undo them easily if you didn't like the change.
          eg. from Mr. Martin's demo: add filter>gaussian blur


          Part 2: Animating on Video Timeline
          We then open the timeline panel by going to Window>Timeline. 

          In this example, Yowa will get smaller and the background larger by the end of the animation.

          step 6: Select Yowa's (subject) layer, and click the stopwatch next to Transform to create a keyframe at the beginning.

          Fig 8.5: Click stopwatch to create keyframe

          step 7:
           Drag the blue arrow to the end of the timeline. Click the stopwatch again. 
          Press [cmd] + T to transform subject and shrink by centre anchor i.e. [opt] + [shift] while dragging. Press [enter] to create new keyframe at this point of the timeline.

          Fig 8.6: Creating 2nd keyframe for Yowa

          step 8: Repeat the same for the background layer, but increase its size at the end of the timeline.

          Fig 8.7: Creating 2nd keyframe for background

          step 9: To export video click render video, as shown below.

          Fig 8.8: Location of the Render button on Photoshop

          FINAL OUTCOME:

          Fig 8.9: Final Outcome of exercise 1

          For the next example, the process above is repeated, however we will be separating the background, foreground, and subject. 

          Fig 8.10: Separated layers with layer mask

          Fig 8.11: Subjects that will be animated

          In this animation, Yowa will spin clockwise, and the background anticlockwise to create a surreal effect. The foreground will get bigger towards the end.

          Fig 8.12: Animation Progress and timeline


          FINAL OUTCOME:

          Fig 8.13: Final Outcome for Exercise 2

          Part 3: Animating on Frame-By-Frame Timeline
          Instead of clicking the video timeline, for this exercise, we use frame by frame. The end-product will be a GIF. 

          Fig 8.14: Provided Image

          As with before, the subject and background are separated, and content-aware fill applied to create a clean background. The yoga girl layer is then duplicated to create 2 frames.

          Fig 8.15: Layer Panel

          The first frame is set to 0.5 secs, and duplicated.

          Fig 8.16: Timeline panel

          In the first frame, the visibility of the second layer is turned off. Likewise, in the second frame, the visibility of the first frame is switched off. Basically, each layer of the subject corresponds to each individual frame. This is the method we also used in the Typography module.

          Fig 8.17: Visibility of layers adjusted to match corresponding frame

          To animate the second frame, we select yoga girl 02, and go to Edit> Puppet Wrap. Pins are placed according to the skeletal structure to allow for movement that looks natural and human. The pins are then slightly moved (movement according to pins). Press [enter] afterwards, and voila you're ready to export the GIF! (Save for Web)

          Fig 8.19: Final Outcome of exercise 3



          Reflection

          I quite liked that our classes were more based on practical hands-on learning. Doing these exercises alongside Mr.Martin's demo tutorials was really helpful and effective in helping to solidify some of the basic tools and features of Photoshop. I feel a lot less overwhelmed with Photoshop by the end of this module for sure!
