Same sunflowers as last picture, however this time done in IR with the Laowa 11mm f/4.5. The wide angle in conjunction with IR filtering makes for a dramatic sky.
Interestingly, some flower head features are not IR-bright, which is unusual. The disk florets are IR dark, a parallel to the bracts (phyllaries) of dandelions which also appear IR black. The IR-dark phyllaries are seen on the sunflower heads too.
