Digital architecture is the making of the digital world – file formats, software, basics of how computers generate the things they do. Manipulating digital media and based on the materials you use would create different outcomes.
Compressive Processes
- Resolution
- Framerate
- Colour Bit-Depth
- Colour Subsampling
- Intraframe Compression
- Compression Codecs
Resolution
- Pixel resolution
- Standard definition
- High Definition
- 4K, 6K, 8K
Resolution- talking about the pixel.
Overall resolution=horizontal pixel count x vertical pixel count
72 pixels in an inch as a rule
- Full HD: 1080p – 1920 pixels x 1080 pixels = [16:9]
- Standard Definition: 480p – 640×480
- High Definition: 720 – 1280×720
Framerate – Frames Per Second
- 15fps
- 24fps
- 60fps
Colour Bit-Depth
- 1 Bit
- 8 Bit
- 16 Bit
- 32 Bit
1 Bit = a binary system containing two possibilities, either on or off. Figures out pixel by pixel
8 Bit – 256 possibilities as doubling 1 bit 8 times. 265 values from black to white, no colour but has 256 choices in brightness
Colour Banding – fine gradients compressed into 8 bit. Jpegs bad do RAW codec as much as possible, 16 bit model compared to 8. 8 SUCKS
Colour Channels and Alpha Channels
RGB+ – Colour and Transparency Channels
Colours are transparent but are just told what colours to be.
All cameras do not have an alpha channel, only the computer has an alpha channel. It’s transparency and only comes up in post – for opacity, masking. Anti aliasing creates small steps between opacity and transparency
Additive Colour Space
- 255 Green Channel
- 255 Red Channel
- 255 Blue Channel
Each pixel is made up of a certain value of each colour
Colour Subsampling
4:2:0
4:1:1
