These Oyster Plant Seedheads are common along the roadsides and in fields from late Spring to early Summer. There are numerous issues in trying to get a sharp digital or film negative with this subject. The first hurdle is wind, which is abundant (by the design of natural selection) this time of the year. When you try to cut one and bring it to the car, it turns out like when you were a child and blew into dandelion seed heads to enjoy the subsequent flight of the many parachutes containing seeds. Bring a five gallon pail to hold over the sample while you pick it gently and carry it back to your vehicle that way, being cautious not to bump the pail against the seedhead. The second issue in photographing this species occurs once you have it in your studio and involves focus. As there are layer upon layer of the parachute-like seed heads, each gossamer fine, when looking through your viewfinder and focusing, you will immediately notice that once your selected focus point is sharp, all else is not. Carefully select one "most forward facing" seed bract that is closest to the lens to focus on and do so on your camera's live view (on the LCD screen itself). Do this at maximum magnification. Before taking the exposure, stop down your macro lens to a small aperature (F16 or F22) to provide maximum depth of field. Many of the better digital and film SLRs have depth of field preview buttons on them so you can depress it and watch the entire seedhead come into focus. Give it a try this spring or summer. Most of this species, due to wind and rain, is gone within days of maturation, so don't wait too long.
