Thanks, LMH. I built a "light-box" or whatever the professional photography people call it. It has two translucent side panels and interchangeable back panels that are opaque (white or black). Each panel is 24" wide and 32" high, so it will handle a pretty large plant. The "floor" is flat black. I can either use it with natural (east exposure) light or use two miniature flood lights. I just took this pic of my 'Emerald Isle' using the light-box. I am using 9:30 AM, natural (east) light. I am still experimenting on what works best - lighting/aperature/exposure time/zoom.
This 'Emerald Isle' originally had three buds but while transporting the plant for a local garden club presentation, two of the buds broke off. I now know to bubble-wrap the buds/flowers to prevent this from happening again. This plant was a division taken from a "mother" plant in January, 2012. The mother plant had 34 blooms, and was in constant bloom from the end of August, 2011, until the end of December, 2011. These flowers are very fragrant. This particular flower is now three weeks old and still looks wonderful. I sell these particular divisions on my web site.
