LECTURES

Week1
This is the first lesson of DPI, and we met Mr Martin. Sir brief us about the module information. After that, we were asked to create a google drive that included 4 files and also creates an E-portfolio. We started our first project. There are three physical collages, and three graphic designs that we like from Pinterest and play the bezier game.

Playing this Bezier game is to let us learn and be familiar with using the pen tool in AI and PS.

Week 2

For week 2, sir teaches us some functions about Photoshop that we will use later, such as pen tool, lasso tool, and how to draw the shadow. We listen and practice in class. Afterwards, sir gave feedback for our physical collage work and decided which will go with the final outcome.

Hot key (windows user) learnt in class:

• ctrl+A: select all
• ctrl+T: select a particular layer
• c&p image: ctrl+A→ctrl+c→(go to file that wanted to paste) ctrl+v→ctrl+T→adjust the size (press shift to not distort it)
• add a mask (at the right bottom column, beside of fx): to make unselected places become transparent.

Week 3: Blending

(public holiday)

Photoshop blending modes

5 mostly used blend modes:

1. Multiply - Darkens an image
2. Screen - Lightens an image
3. Overlay - Boosts contrast
4. Color - Blends only the colour
5. Luminosity - Blends only the brightness

Week 4: Recolouring

We followed step by step with Mr Martin and learned how to recolour a black and white picture into a coloured picture. After we became more proficient in the operation of recolouring a picture using Adobe Photoshop, we were asked to recolour another picture and hand it in as project 1.

Steps:

1. Find references for the hair colour and skin colour.
2. Use EYEDROPPER TOOL to drop the colour and brush it at the corner side.
3. Use QUICK SELECTION TOOL to select the hair
4. Click the MASK button(right bottom beside fx)
5. Click SELECT A MASK at the control bar
6. Select OVERLAY and refine EDGE BRUSH TOOL to brush it on the edges
7. Select OUTPUT TO: LAYER MASK
8. Select SOLID COLOUR( at right bottom like a circle one) and drop the colour
9. Drag the mask of the hair to the solid colour layer
10. Repeat the process at skin, lips, eyes and others.

Week 5: Double Exposure

We watch a pre-recorded video from Mr Martin and follow the step to make a double-exposure picture. We download pictures from google drive (https://drive.google.com/drive/folders/1lDhDvSaro8tW7XCRa14nOqJO9bDRuqS6?usp=sharing)

Week 6

Exposure setting:

1. Iris(guang1quan1)
• A device in lens
• Control the flow of light entering the lens.
• Measured by f-stop:f/1, f/1.4, f/4... (lower f-num, larger lens opening)
2. Shutter Speed(dong4tai4)
• Measured in seconds: 1/1000s, 1/500s, 1/250s...
• slow shutter:Smooth
• high shutter: freeze the moment
3. ISO
• ori referred to the sensitivity of film
• suggest: low ISO
• effect using high iso: trichromatic aberrations, reduce dynamic range, reduce colour accuracy

Lens perspective

Focal length: Focal length is the measurement (in millimetres) from the optical centre of a camera lens to the camera’s sensor.

Depth of field: The proportion of the image that is reasonable sharp and in focus.

Portrait mode=standard lens (zoom in)

Exercise 1: Fabric Displacement Map

(https://drive.google.com/drive/folders/1bA3frtak9eirPa-8TW_dmTZ9t1xhHbW8?usp=sharing)

Steps: change fabric photo into black & white - filter - blur - gaussian blur - save as PSD - c&p flag to a coloured fabric - right click: convert to smart object - filter - distort - displace - select fabric PSD file - change blending mode - select the flag with a selection tool - select bg layer - add a mask - add a new layer - gradient - select colour

Week 7

Spot healing brush tool

reduce brush hardness (<70) - copy a bg layer - add a new layer - select sample all layer (at control bar) - start healing

Fig 7.1-Spot healing brush tool

Healing brush tool

reduce brush hardness (<70) - copy a bg layer - add a new layer - select sample all layer (at control bar) - hold alt select the surrounding colour - healing - repeat alt&healing

Patch tool

copy a bg layer - select area that needs to patch - drag the selected area into an area that wants to replace

Fig 7.3-Patch tool

Fig 7.4-Content-aware brush tool

Dodge tool

add a new layer - edit - fill - content: 50% grey - blending mode: overlay - select dodge tool - reduce exposure volume (control bar) - select those areas that need to brighten up

Week 10

how to parallax: 

1. copy a layer-select the things that want to erase-add a mask-select background layer-edit-fill-content aware
2. right click-convert to a smart object  (both layers)

window-timeline-create video timeline-add a transforming point at the beginning-add a transforming point at the end(transform the photo)-export: an arrow at the left bottom like a forward icon

yoga parallax (will blur when making the layer):

1. do a masked layer on yowa and grass: select yowa / grass-mask-select and mask
2. remove yowa from bg: select bg layer-select yowa roughly-select-modify-expand-5-edit-fill-content aware
3. remove the grass from bg: (same steps as 2)
4. create a video timeline (same steps as a surfer)
   
   

Week 11

3. layer-camera-create camera on 3d view
4. artboard right bottom side 1 view-change to 2 views
   
5. the left side of 2 views-custom view
6. start transform (can see the difference in the second view)
