Crikey, what a set-up.....
Iris in a vase, drop of glycerine on the petal. Copper gerbera placed in a squash bottle in just the right position so as to reflect in the droplet. Hand held 150 watt halogen lamp to the left to light the gerbera then Sam holding another 150 watt halogen lamp to light the iris. All other lights out.
Tripod, f4 at 1.40 second to give emphasis to the droplet. Remote control
Tidy up in PS and hey presto
Hope you like, LARGE and F11 shows off the gerbera even better
