Uploading documents

You can upload documents in plain text (TXT), PDF, and Microsoft Office file formats at a maximum file size of 8MB per document.

Digital image scanning

In order to create digital objects that are accurate copies of an original and able to be re-purposed, good practice is to create a digital master, akin to a negative. Lower resolution copies for specific purposes can then be made from the master.

Scanning black and white images in full colour allows tinting, discolouration and any markings on the image to be more clearly visible, while improving the dynamic range of greys available for revealing detail.

  Minimum (safe) Best practice

File format Uncompressed TIFF, PDF, JPEG - not more than 30% compression Uncompressed TIFF or JPEG2000
Colour space sRGB Adobe 1998 (colour)
Capture resolution 300ppi x output length original length 400ppi x output length original length

Digital photography

The output from a digital camera is dependent on its capabilities. Generally wherever possible the camera’s highest settings should be used to capture as much detail and colour information as possible. If a camera does not support raw image output, the highest detail setting for JPEG is the safest alternative for creating an image that can be re-purposed.
