This is a set of seven photographs of technicians retouching orthophoto reproduction material at the Army Survey Regiment, Bendigo, c1975. Retouching mainly entailed the application of liquid opaque (Plumtree), commonly known as “duff” to cover blemishes such as scratches and spots on film negatives before photographic exposure. Retouching technicians also used specialised techniques such as “needling” to repair faults on the emulsion of map reproduction material. The technicians in this set of photos were probably working on the retouching and registration of orthophotomap colour film separations in preparation for publication by Print Troop. Peter Dew featuring in photos .1P to .5P was a serving member of RA Svy, who died in a tragic accident at home. He was fondly remembered as one of Lithographic Squadron’s colourful personalities. The Peter Dew Memorial Award was a humorous novelty award generally presented annually to a member of the squadron selected as the "Super Animal of the Year." To view a photo of this award, refer to item 6230 of the Victorian Collections.

This collection of five photos was most likely taken at Lithographic Squadron, Army Survey Regiment, Fortuna, Bendigo in c1970s. The main tasks undertaken by technicians in Photo Troop were most likely enlargements, reductions and duplication of map reproduction material, and processing of aerial photography.

Orthophoto mapping provided the Survey Corps with the capability to produce map products quickly in the event of a crisis. These are four photographs of equipment used by the Army Survey Regiment to produce orthophotomaps. The Wild GZ1 orthophoto projector shown in photo.1P was introduced in 1973 and was the first equipment used to orthorectify colour and monochrome film aerial photography. Height profiles were originally produced on a PEB8 Stereo profiler and later were software generated. Photos of the PEB8 are available in Victorian Collections item 6222.17P, photos .5P and .6P. In the same era the IBM 1130 computer; OMI/Nistri AP/C-3 analytical plotter with coordinatograph, OP/C orthophoto projector and Zeiss Planimat D2 stereoplotters were introduced. Orthorectification is the process of removing geometric distortions and scale errors/variations from images. Images have tilt and relief distortions that make it difficult to compare accurately a map and an image of the same geographic area. Once an image is orthorectified, features on the image are shown in their planimetric locations. The WILD OR1 orthophoto projector and workstation shown in photos .2P to.4P was introduced in the mid-1980s. It was the second-generation equipment used to orthorectify colour and monochrome film aerial photography, replacing the system introduced in 1973. See items 6124.5P and 6133.4P for more photographs of orthorectification equipment.

These four photographs of orthorectification equipment were taken at the Army Survey Regiment at Fortuna, Bendigo, c1975 and c1988. The photos are on 35mm colour slides and scanned at 96 dpi. They are part of the Army Survey Regiment’s Collection. .1) - Photo, colour, c1975, Wild GZ1 orthophoto projector. .2) - Photo, colour, c1988, WILD OR-1 unrectified colour photo in carrier, orthorectified and re-scaled colour image. .3) & .4) - Photo, colour, c1988, WILD OR-1 Orthorectification Workstation

These nine photographs were most likely taken in c1988 in Lithographic Squadron at the Army Survey Regiment, Fortuna, Bendigo. The equipment operated by the technicians is the KLIMCH camera. The main tasks undertaken by the technicians were most likely enlargements and reductions of map reproduction material. The KLIMSCH Commodore camera was introduced in 1953 and was the largest in the Southern Hemisphere. It was replaced with a new model of the same size in 1979. The new model with its computer-based interface provided productivity gains with improved speed and its consistent results led to less wastage in time and materials. Its variomat lens system provided improved retention of map feature linear weights during the camera reduction process. The camera which was specially made for the Army in Germany was fully automatic and power operated. It was claimed to be one of the biggest automatic cameras of its type in the world. It was made to the specifications of the Royal Australian Army Survey Corps to assist in the production of the very high standard maps for the Army. There are several more photos catalogued in the Victorian Collections database of RA Svy personnel operating the KLIMSCH camera.

This is a set of four photographs of technicians operating the KLIMSCH Camera at the Army Headquarters Survey Regiment, Bendigo c1988. The photographs are on 35mm colour slides scanned at 96 dpi. They are part of the Army Survey Regiment’s Collection. .1) - Photo, colour, c1988, KLIMSCH Camera. .2) - Photo, colour, c1988, KLIMSCH Camera, unidentified technician. .3) - Photo, colour, c1988, KLIMSCH Camera. .4) - Photo, colour, c1988, KLIMSCH Camera, L to R: unidentified technician, CPL Paul Baker. .5) - Photo, colour, c1988, KLIMSCH Camera. .6) & .7) - Photo, colour, c1988, KLIMSCH Camera, unidentified technician. .8) & .9) - Photo, colour, c1988, KLIMSCH Camera, SPR Russell Pajank.
