Testing long exposures in different environments

We recently investigated how long exposures during digitization might be affected by different physical locations. We tested 4 locations and 2 shutter speeds to capture the blur induced by walking heavily around the copy stand during exposure.

The 4 areas tested were:

  1. Concrete Foundation at the ARC
  2. 7th floor of Alkek Library in the Corner of the Building
  3. 7th floor of Alkek Library in the Center of the Building
  4. 2nd floor of Alkek Library on a Raised Floor installed over carpet for data & power lines

We tested 2 shutter speeds that are representative of those we use to digitize film negatives using Artograph LightPad Pros:

  1. 1/10th of a second
  2. 1 second
