How colour photographic prints differ from digital colour
Dyes, light, and why a warm filter does not date a photograph.
A faded or warm-toned print may suggest age, but appearance alone is not a reliable date. The process that formed the image matters, as does the way the print has been stored.
Chromogenic colour
The Image Permanence Institute describes chromogenic materials with layers sensitive to different parts of the spectrum and dyes formed during development. That is one chemical route to a colour photograph, not a description of every colour printing system.
Evidence: Process reference
A colour effect is a choice
A digital warm cast can be added to a brand-new image. Conversely, a well-preserved historical colour photograph may not look faded. The room’s lighting, camera white balance, paper and later scanning can all affect what a viewer sees. Name the effect instead of inventing a processing history from it.
Choosing a look in the app
Disco ’78 offers warm colour; Flash ’96 emphasises a bright colour-flash mood; Instant ’98 uses a faded-colour direction. Those are current creative labels. Start with a neutral light source if you want to compare looks fairly. Keep the same subject and composition, then judge the versions together instead of comparing unrelated pictures.
