HAP (Historical Aerial Photography)

The collection has been acquired over a number of years from 1930 through to 2005. The imagery was originally captured using a variety of cameras including the Wild RC-5, RC-10 and Leica RC-30 cameras with a variety of lenses with focal lengths of 88mm, 153mm and 304mm. Images were captured in monochrome or colour during this period at a range of scales ranging from 1:10 000 to 1:80 000.

Images have been digitised from either the aerial film negatives or hard copy prints up 2000dpi resolution depending on the scanned medium.

These are standard 600dpi unprocessed frames as JPG’s

The HAP collection has been digitised from either the aerial film negatives or hard copy prints up 2000dpi resolution depending on the scanned medium.
