I second the motion to get a digital camera. The flexibility and control that a good digital camera offers is amazing, and the monetary savings of not having to pay for film and film processing makes your photography practically free after your initial investment. With silver at about $12/ ounce these days, I'd hate to see the current prices of film and processing for conventional photography, which is a silver-based technology.
When shopping for a camera with which to photograph my jewelry I did exhaustive comparative shopping for an affordable digital camera with superb macro (close-focusing) performance, and the better Nikon Coolpix cameras trounced all the competition by an extremely wide margin. I remember that barrel and pincushion distortions were a major issue in the Sony and Fugi cameras. I bought a factory reconditioned Coolpix with a five year warranty extension on eBay for 4 or 5 hundred dollars and it has performed wonderfully. No special macro attachments or lens needed.
Forget the macro flash "ring-lights"; the lighting they yield is quite harsh. When back-lighting the reeds, make sure the light from your back-lighting lamp doesn't shine directly into the camera lens; some sort of barrier will be needed. If you wish to soften the light falling on the front of the reeds, make a frame out of clothes hanger wire and put one or two layers of white trash bag plastic over it, then suspend this over your lights.
