I took this photo of a pen afficianado whose get-a-way from his day job hobby is anything to do with pens - especially reshaping nibs for other people. This shot is full frame from a D3 only resized to long side 1200 px. Original shot is 300 dpi. What I am looking for is a [free] shot of some sparks coming off a grinding wheel. My intention is to photochop them into this image (skillfully, I hope) to make the sparks appear as if they are coming off the nib when it is contacting the grinder wheel. Title it up, nick like, attach to gator board so the pen guy can advertise his presence at other local pen events.
