5D Mk IV – EF 70-200mm f/2.8L – f/32, 1 second, ISO 50

Hoosier Crossroads Wind farm outside our back yard. It was really cold out when I took this picture. To get the ‘fan blade effect’, I had to put the ISO very low and the f-stop very high. Plus, I had to wait until dusk so I could put the shutter speed low enough.

EDIT: 2/21/2022 – I can improve this shot tenfold by purchasing neutral density filters.
