Interesting that they can differentiate between books, writing, photography, painting or any other forms of material produced on a Grand trip.
Seems to me they are all art forms and they should not be able to isolate one from another. I could see how this originated with the thought that filming would generate from a production crew that could be disruptive to other peoples enjoyment and the environment. But now with the boom of first person perspective cameras like go-pro, etc this seems unrealistic and penalizes one form of speech over another. I imagine many a writer, painter and photographer on a private permit have profited from material produce. Wondering if this is what allowed the other solo trip film to be produced.
