Practice question · Sort into groups
Sort each step by where it sits in the input-output chain.
Groups: Input · Processing · Output
- Lens projects image
- Tonal and colour edits
- Photosite quantisation
- File resampled to 300 ppi
- Demosaicing pixel data
- ICC profile print mapping
Hints
- Anything that happens before a file exists is input.
- Anything tied to a specific paper or screen is output.
Show the answer
Input: Lens projects image, Photosite quantisation
Processing: Demosaicing pixel data, Tonal and colour edits
Output: ICC profile print mapping, File resampled to 300 ppi
Why
The three stages are worth keeping separate because they fail differently. Input losses are irrecoverable, processing losses are recoverable if the original is kept, and output losses are recoverable simply by printing again. Most panic about image quality is about the only stage where nothing is lost permanently.
