Cleaning crew giving Tacoma Dome back its shine

A six-man cleaning crew with brushes and pressure washers is helping the Tacoma Dome shine again.


The Associated PressTACOMA, Wash. —


A six-man cleaning crew with brushes and pressure washers is helping the Tacoma Dome shine again.


They're a week into a job expected to last about a month, rappelling from the 150-foot tall cupola with 30 pounds of gear strapped to their bodies.


The News Tribune reports they've found tennis balls and a 9mm bullet in the gutters, which are mostly full of foul-smelling sludge.


This is the third time the 520-foot diameter roof has been cleaned. The last cleaning was in 2003. A private donor is paying about $104,000 for the work because the city couldn't afford to keep its landmark clean.

Macro and Close-up Defined

Canon EF 100mm f/2.8 Macro USM Lens


The photo above was taken with a Canon macro lens on my Canon 30D camera. The size of the sensor on that camera is 0.59 x 0.89 in. Using a Canon 100mm macro lens set at 1:1, I was able to photograph about .85 in of the metal tape measure.

According to Canon USA, an image taken at life size records the subject at actual size on the film or digital sensor. "For example, if it has a diameter of 1 in., it will occupy 1 in. of your actual slide or negative. With a digital SLR, at 1.0x magnification, the image projected onto your camera’s sensor will likewise be the same size at the sensor plane as the actual subject itself."

This relationship is described as 1:1, because the subject is reproduced on the sensor or film at its original size.

The Photographic Society of America describes macro photography as life size (1:1) to 3 times life size (3:1).

In the photograph below, George Washington has been recorded on the Canon 30D sensor exactly the same size as he appears on the $1 bill.

 According to Barbara and John Upton, close-up photography can be defined as anything from one-tenth lifesize to a 1:1 life sized image. (Upton, Barbara and John Upton, Photography (second edition), Boston, MA: Little, Brown and Company, 1981: 250).

35mm film and  full sized dslr sensors are 0.94 x 1.41 inches. Using the Uptons' definition, a close-up photograph would be of an object 9.4 x 14.1 inches or smaller.

Most non-professional dslr cameras have a sensor similar to the 30D - 0.59 x 0.89 in. By the Uptons' definition, a close-up taken with most dslrs would be of an object 6 x 9 inches or smaller.
