The biggest value of using large format it the ability to make 1:1
prints as a contact print with astounding detail. Consider if you
will a 66M punch block and the value of getting tack sharp images of
every tool mark, every scratch, and every wire or connector on the
block. Sure, you could use a strong light and a magnify glass, but by
sending in a photographer the day before you get to the wiring
analysis who then provide you with 16x20 prints of what you will
later be inspecting which can save you a ton of time, but also makes
you more effective in your search.
If the sweep is local to the Boston area I can get the film
professionally developed and printed in under two hours, 24 hours per
day on a drop off basis (four hours if their courier does the
pickup), or about 30 minutes if I stay with B&W and do the processing
and printing in-house myself.
I use a Toyo 8x10 field camera myself
http://www.toyoview.com/Products/810MII/810MII.html the system can be
transported is a fairly small 18x18x8 case or satchel along with a
couple of lenses.
To avoid using a focusing hood I cross two lasers at the point of
focus, and have this focus point marked on the frame of the camera,
plus two bubble levels to keep the camera from titling. Then two very
powerful ring strobes which mount around the lens barrel to the lens
board so that I get tack sharp pictures.
From an operational point the camera does not look like a piece of
sweep gear and the last thing an eavesdropper will suspect is that
the photographer is actually hunting him. Plus if you set up a
tripod, some lights, and with a large format camera in an executves
office the spy is more likely to think that it is a photo shoot, and
not a spy hunt. No matter that the tripods and "lights" actually
conceal some huge antenna's and the "flash controller" is actually
performing an RF survey.
Yes, that may very well be the CEO is an all day photo shoot with a
photographer for a national magazine or news media, or it could just
be that the spy is about to get his carcass nailed to the fence post
The camera is could all be about distraction and why so much
equipment gets dragged in to the building on a Sunday, the room gets
set up on a Monday, various pictures get taken around the building on
Tuesday, and the executive is seen with the photo crew while parts of
the building gets closed off during the shoot.
Shucks, there is quite a bit you can do with cameras and bug
sweeps... some of which has nothing at all to do with taking pictures.
