I decided I wanted to build a ring flash, and Mike, Toby, and Dennis were interested too. So we all went over to Mike's one Saturday and spent a fun afternoon with power tools.

1: I got a 6-inch to 4-inch PVC conversion piece, and used that for the base of the flash. The dotted line is where the centre piece ends; I need to saw the PVC off at that point. |
2: Mike let me borrow his Nikon 105mm AF-S macro lens; in exchange, he tried out my Sigma 30mm f/1.4. Here, he is gazing sceptically at how the third-party, non-Nikon-branded lens looks on his D70s. :) |
|
5: Toby's throttle assembly (through the 105mm) |
8: My first shot with my ring flash is of Mike trying out his ring flash. :) |
|
9: Toby, lit with ambient light and my new ring flash |
11: I wanted to see how uniform the illumination of the ring flash was, so I took it off the camera and balanced it on top of my Vivitar (on a light stand). Dennis kindly steadied it as I lined my shot up. (Answer: there's some falloff, but it's not bad at all!) |
|
13: Blinding Toby with the flash (with the shutter closed way down to kill the ambient light) |
14: I borrowed Mike's 105mm lens again, and took a series of photos of a dandelion in his front yard. The focal plane in this shot is right on the leading edge of the dandelion. |
15: Here, the focal plane is between the leading edge and the core. |
16: Pulled the focal plane back to the edge again. |
|
18: Mike asked me to take a shot of his new knife. |
