My friend Brad and I changed the final drive oil and installed a new rear tire on my GSA yesterday. He's been in a big polishing mode lately, so he wanted to give my exhaust pipes the once over. Only happy to oblige, "Knock yourself out," I said.
Brad polishing in his garage. This photo is backlit--the meter is fooled by the bright light eminating from the background.
Here's the same shot, same lighting, only this time I activated the camera's built-in flash which does an admirable job of bringing the subject out of the shadows.
This is kind of a fun shot. The flash fires at an extrodinarily high speed, somewhere in the vicinity of 1/10,000 of a second; however, the exif reveals that the shutter is only firing at 1/60th. As a result, the wheel does show slight motion blur, but because the flash is the primary light source in this photo, it does an admirable job of freezing the buffing wheel which is spinning at God-only-knows how many RPMs.
Check out these before-and-afters:

Whole polishing process took fewer than 30 minutes. These aluminum pipes now look like they're chrome. Brad says an occasional hand touch-up will keep this looking bright and shiny.
