The Restored Scan: Digital Alteration and Colonial Watercolour
A publisher wants to reproduce a nineteenth-century watercolour, Harbour with Cutter, in a book on colonial New Zealand art. The original has faded. A high-resolution scan was made under mixed lighting without a colour target. A local designer has produced a digital 'restoration' that boosts saturation, removes foxing, and reconstructs lost detail in the sky. The artist's descendant objects to the altered version, saying it misrepresents the family's ancestor. The publisher's deadline is two weeks. The author wants the 'true colours' shown and argues that the faded original is misleading. The designer says the restored image is 'what the artist intended'. The book's captions have not been written. The original is too fragile to travel for rephotography, but a conservation studio could make a new scan with a colour target in five days at a cost that would use most of the image budget.
1. Advise the publisher on which image to use and why.

The publisher should use the unaltered scan as the primary reproduction, because a scholarly book should show the object as it exists, not as someone imagines it once looked. The faded surface is part of the work's history and condition. If the restored image is used at all, it must be clearly labelled as a digital interpretation, not as the watercolour's appearance. The author's argument that the faded original is misleading is understandable, but it confuses conservation with reconstruction. The designer's claim about 'what the artist intended' is unprovable without documentary evidence of the original palette. The better use of the budget is a new scan with a colour target and a conservator's report, which would give a more accurate record of the current surface. If that is not possible, the existing scan should be colour-corrected conservatively against a grey card and the caption should note the lighting conditions. The descendant's objection is relevant because the family has a stake in the representation, but the primary ethical duty is to the object and to readers.
2. Draft caption wording that would allow the restored image to be used responsibly, if the publisher insists.

If the restored image is used, the caption must say so plainly. Example: 'Harbour with Cutter, 1860s. Watercolour on paper. Digital interpretation: saturation increased, foxing removed, and losses in the sky reconstructed by [designer] in 2024; the original is faded and unrestored. Compare with the unaltered scan on page X.' The caption should not say 'restored to original condition' unless there is evidence for the original colours. It should name the intervention and its date. The book's introduction should explain why the publisher chose to show both images, and the author should not use the restored version as evidence for the artist's palette. If the descendant is named in the book, their objection should be acknowledged in a note. This approach treats the restoration as an interpretation, not a fact. It also gives readers the chance to see the difference, which is more educational than presenting a single 'true' image.
3. What are the ethical issues in digitally removing foxing and reconstructing lost detail?
Read the worked answer
Foxing is evidence of the paper's history and condition; removing it changes the object's appearance and can hide provenance or conservation information. Reconstructing lost detail in the sky is more serious because it invents content that the artist may not have painted. The ethical issue is not that digital alteration is always wrong, but that it must be transparent and justified. A conservator would not repaint a watercolour without documentation, and a publisher should not do digitally what would be unacceptable physically. The descendant's objection also raises questions about cultural authority and family memory: the image represents an ancestor's work, and the family may have a legitimate interest in how it is shown. The author's desire for 'true colours' is a desire for certainty that the evidence cannot supply. The responsible path is to show the unaltered object, explain its condition, and if a reconstruction is included, present it as a separate hypothesis with a clear label. That respects the object, the reader, and the family.
