My brother produced this pair of Pioneer headphones, while he was looking for a soldering iron. Our current 'get the GPS working again' state of mind was not congruent with my desire to photograph the set, so I asked if I could borrow them for a couple of days. After we finished getting the GPS running, Christmas happened, and the SE-L 40's sat atop the refrigerator, thankful to be out of the shop.
On the last day of 2009, I managed to return to the headphones. Using black fabric as a backdrop, I maneuvered my tripod and camera to a composition that I was happy with. I put an extension ring between my camera and the telephoto lens, ensuring that I would be able to focus on something that close to the camera. Then came the boring part.
On manual exposure and white balance, I painstakingly moved the focus ring through ten different positions, sat and waited until the camera wasn't shaking and then triggered the camera using my cable release. Wash, rinse, repeat.
Patience is only needed when trying to steady the camera. A lens that long will magnify any shake in the camera. Furthermore having an abusively large camera on the end of a stick doesn't help all that much either.
The reasoning for my madness is to defeat depth of field and produce the image I wanted. At 200mm focusing 30-40cm in front of the camera means that your focal plane is thin. In practice, when I was focusing on the tip of the plug, where it morphs into fabric wrapped wire started to show some comfortable bokeh. Sharpness at the front of the image resulted in a unrecognizable, out of focus, blob at the back.
With my sequence of focus planes, I used a focus stacking software to sandwich all the images into a final image. Focus stacking software detects the sharp portions of each image to use in the final output. I used a program called Helicon, although if you are looking for some other Focus Stacking software there are more to choose from. Technically the image is 'rendered', and not really a 'photograph'. Although I don't see much difference between using one algorithm to sandwich focal planes together versus using another to sharpen all the edges within a photograph. Is one photography while the other isn't?
