Type of Artifact
- Black or neutral grey background
- Artifact catalogue number
- Colour or white-grey-black scale
- Artifact placed straight
- Ensure that the catalogue number and scale can be excluded if necessary
In the Studio
- At the beginning of each session with new lighting, adjust the camera's white balance and for reference purposes, photograph a Kodak Q-14 colour scale.
- Import the image into image-processing software (e.g., Photoshop®) and adjust the "levels" on the colour scale with the points of reference indicated in the general guidelines.
- Save the data in ALV format, since this information will apply to all photos taken during the same photography session.
Taking the Picture
- Place the colour or white-grey-black scale (showing measurements) at the foot of the artifact. Save space on the lower right to record the object's catalogue number.
- Photograph the object a single time, with an appropriate measurement scale.
At the Computer - Image-Processing Software
- Apply the ALV information to all images within the same studio session.
- Works well for batch digitization and improves productivity, but does not offer optimal rendering of individual images.
- Type the artifact's catalogue number in the lower right - in white if the background is black, and in black if the background is neutral grey (font: Arial, 40 pts.)
- Flatten the image (i.e., flatten layers)
- Convert in Adobe RGB 1998 profile, 8 bits per channel (total 24 bits).
- Save the image as an uncompressed TIFF, named to standards established by the Corporation's Photo Archives.
- Produce a JPEG version as described in the general guidelines.
