Close-up near infrared profile photo of the centre of a Rudbeckia fulgida var. sullivantii 'Goldsturm' flower. In infrared the anther cylinders, although lighter than they appear in visible light, retain a relatively dark tone. In contrast, the Corollas, which appear dark in visible light, are quite bright in infrared. Similarly, the pistils are also much brighter. The petals, while fairly bright in visible light, are even brighter in infrared.
White balance and exposure reduced, dust removed in ACR.
