Conservators rarely have the opportunity to access made-for-conservation equipment, software, tools or chemicals. We borrow and adapt things intended for other environments. Conservation labs are often populated with dental tools and equipment, surgical scalpels, entomological stainless steel pins, book binder’s presses and felts, as well as a tradesman’s array of socket sets, drills, punches and pliers. We put Tyvek® Homewrap® covers over collection objects as it is breathable and keeps off dust. We transport small objects in prawn crates and often display costume on off the shelf mannequins.

When it came time to document the Cape Bowling Green Lighthouse prior to major conservation work, our conservation team turned to technologies which are often used by insurance companies and real estate agents to photograph buildings and record damage.

New South Wales hosts a wide variety of historic shipwreck sites. These range from large, fully exposed and intact hulls to smaller, largely disarticulated, dispersed, and buried structural components and artefacts. The environments in which these sites exist also differ significantly in terms of seabed composition, water depth and water clarity.

The museum’s maritime archaeology team recently visited the shipwreck site of the late nineteenth century steamship Centennial. The dive was part of an ongoing initiative to document selected historic shipwreck sites within Sydney Harbour with digital photography and videography. Still images and video footage collected during the project will be used to generate 3D digital photo-mosaics of these sites and test the usefulness of this recording method in a variety of environments.
