This higher magnification shot was done with a 100 mm macro lens.
Today, four days later, another one has opened. I moved in very close for this (same lens as above) and waited for any vibrations to settle to a minimum. The light was dim (it was almost 6:30 pm EDST), the exposure time was 1/4 second, so of course the camera was on a tripod.
This flower was being visited by a fly, whose red eyes provided a nice color contrast. A little cooperation for a change! It remained stationary for the long exposure.
