Close-up of white orchids with the Zeiss Touit 50mm f/2.8 macro lens

This orchid plant has been in our living room for about a month. Today I put it near the window where it was back lit, and photographed it with the Zeiss Touit 50mm macro lens used wide open at f/2.8 on the Fuji X-T1.  I used the lens wide open to obtain a shallow depth of field with the main focus just on the stamen of one of the flowers. I wanted to contrast the large white areas of of the flowers and with the small bright colors in their center.
