I am not a lawyer, and this is not legal advice... This not-legal-advice pertains to the UK.
Copyright does not subsist in 'anything you do'. It only subsists in the following works:
- Original literary, dramatic, musical or artistic works.
- Sound recordings, films, broadcasts or cable programmes.
- The typographical arrangement of published editions.
In this instance, I suppose the assumption would be that the author was claiming it was an artistic work; that seems to be what Damien Hirst claims when he slaps a corpse in formaldehyde and calls it art. An Artistic Work is defined in UK copyright law as:
- In this part "artistic work" means -
- a graphic work, photograph, sculpture or collage, irrespective of artistic quality,
- a work of architecture being a building or a model for a building, or
- a work of artistic craftsmanship.
- In this part - "building" includes any fixed structure, and a part of a building or fixed structure; "graphic work" includes -
- any painting, drawing, diagram, map, chart or plan, and
- any engraving, etching, lithograph, woodcut or similar work;
"photograph" means a recording of light or other radiation on any medium on which an image is produced or from which an image may by any means be produced, and which is not part of a film;
"sculpture" includes a case or model made for purposes of sculpture.
On reading, that means the question you've got to ask is, are the slides (in the non-photographic sense of the word) "a work of artistic craftsmanship."
In truth, there is only one man who can tell you the answer - the judge, after it goes to court. No matter how much you pay a lawyer, all he's going to give you is "advice"; if there is a directly relevant piece of caselaw providing precedent, his advice is extremely useful - if not, it's probably about as much use as the next man's. What their advice - or any other research you get - can do is allow you to properly judge your risk and so sensibly evaluate the right thing to do, and it also gives you the appropriate confidence required for the lawyerly willy-waving match with them if they did threaten court action. (The majority of cases are in fact decided in the latter way - "my lawyer is more confident/louder/went to a better school than your lawyer, so you're going to back down.")
*Personally* I'd say you'd be fine; the differences between Mr Hirst's dip-and-dunk formaldehyde work and your slides, to my mind if I were involved in a case involving either, would be that
- Mr Hirst uses artistic judgement in the selection, composition & display of his samples - this is not true of a simple cross section or mounting of a bug.
- Mr Hirst's are one-off works hand crafted by him (or more likely the low-paid labourers who do it for him) not mass produced on a conveyor belt.
That's just my view though
