Panchromatic Rainbow

I had the camera set up in my bathroom windowsill, just waiting for the sun to emerge, when I got a bonus rainbow in the bargain. Randers, Denmark, 2016. Burke & James 4x5 press camera, Schneider 150mm Xenar with 2- diopter (f=224mm). Front rise. Fomapan200 processed in Rodinal 1+100.
