Sometimes an subject is so lovely that it takes ones breath away. This Rosy Veincap (Rhodotus palmatus) is one such subject. It was found earlier this summer on the bottom side of a small log that was kindly rolled over by a friend as we all hunted beautiful and unusual fungi. The lacey network over the top of the caps is just visible on the lower right. The undersides of the caps, with their lovely gill structure, are as striking as the tops. It is found in deciduous woodlands in eastern North America. This coral pink color is rare among mushrooms in this part of the country.
The dark log, pink caps and white stalks present an exposure decision, The camera exposure was opened 2/3 stop to keep the white stalks white and account for the lighter than medium pink gills. When in shady areas with medium and lighter than medium subjects we often open up from 1/3 to 1 1/3 stops. This moves the histogram to the right and provides more information on the digital file. We estimate the amount by the proportion of the frame that is light colored. There is no formula, just an intuition. And, of course, with stationary subjects it is easy to adjust the exposure after looking at the histogram and make another capture.
