[Work In Progress] Architectural Rendering using Adobe® Photoshop® CC 2014
This presentation is work in progress. Please send me feedback if any. Thanks!
2 The Three Principles 1. Standardize Workflow for Productivity. Your PSD file should be readable and reworkable. Design keeps changing until deadline and your colleagues often edit the file. Would you like to spend half an hour describing which layer is what for? 2. Think about Physics. For Photorealistic Rendering and Consistent Workflow. Rendering software is based on physical model — Why not us? 3. Learn How It Works, Not Point and Click. There are many tools other than Photoshop. Nuke, After Effects, Flame, DaVinci Resolve, GIMP, Krita. Once you learn how things work, you will only need to learn operating software.

5 Basic Knowledge 1.1 Workflow and Equipment 1.1.1 Workflow Overview There is only 2 elemental steps. 1.1.2 Equipments Do we really need graphics tablets? 1.2 Digital Images, Digital Colours 1.2.1 Trend of Digital Image Processing Is this workflow perpetual? 1.2.2 Colour Models Why 3 prime colours, not 2 or 4? 1.2.3 How (Digital) Camera Works From Objective to image files
1.1 Workflow and Equipment
1.1.1 Workflow Overview There is only 3 elemental steps.
8 Rendered Result
Đ Low contrast, flat appearance of usual render results.
Đ Note that “Realistic” and “Photorealistic” are different.
9 Add Object
Ɖ Step 1: Place object onto the scene.
Đ May need to adjust blending modes for luminant/transparent objects.
10 Transform and Mask
Ɖ Step 2: Arrange object correctly in the scene.
Đ If object is hidden by other objects, masks may be needed.
11 Colour Correct
Ɖ Step 3: Match object colour to scene.
Đ May also need mask. Note that top half of the tree is brighter.
12 Composited All Objects
Note that The colour of building remains unchanged.
Đ Lights inside windows are composited using blending mode screen.
13 Add Environment Effect
Đ Added fog, star burst, diffusion and raindrops.
Note that the Effects reflect colours of each lights.
14 Colour Grade
Đ Colour, Contrast or other edits.
Đ [Advanced] You may use Adobe Lightroom for productivity. In this case, some gradient filtres are aplied using Lightroom.
1.1.2 Equipments Do we really need graphics tablets?
1.2 Digital Images, Digital Colours
1.2.1 Trend of Digital Image Processing Is this workflow perpetual?
