Parkinson was draughtsman to Joseph Banks, the great naturalist who accompanied Captain Cook on his southern world tour. These images are from the same book but the Chief is a direct digital scan from the book housed in the Sir William Dixon Library at the State Library of NSW. It's on display with other miscellaneous rare book images.
The Heiva image was produced by optical character recognition (OCR) scanning of a photocopied microfilm. All the engravings from Parkinson's journal are displayed among the National Library of Australia South Seas Voyaging Accounts exhibition.
The OCR Chief image for comparison - click on the image for a zoomable flash interface. The black and white image has its own intrinsic aesthetic merits for mine.
