(2) The location of where each photograph was taken should be shown on a site plan or
floor plan as applicable.
d. Digital Imaging (if available). Digital imaging may be used in lieu of photographic
drafting. The use of digital images can eliminate film processing time, improve printed image
quality, and reduce the effort required to produce photographic drawings.
(1) Like photographic drafting, digital images can be used to show existing conditions
and provide instructions for the required work. The location of each image should be shown on a
key plan for reference.
(2) Digital imaging involves three phases:
(a) First, the digital images are "captured" with a digital camera or a graphics
(b) Second, the digitized images are transferred to a PC or CADD workstation for
viewing and editing in appropriate graphic standard formats; and
(c) Third, the images are printed on copying machine sized drawings metric sheet size
A4, 210 mm x 297 mm (8-1/2"x11") or A3 280 mm x 430 mm (11"x17").
(3) Other advantages of digital images include:
