Mt Cowan Thunderheads

I've watched some fascinating thunder storms over the last few days.  Seeing Marc Ward's "Siesta Key Storm" post in M&N and reading his processing approach got me to trying my own variation of his method mostly using the Lightroom raw processing module and starting with going to Tungsten as the white balance setting and darkening the blue slider in b&w mode.  There was some burning/dodging in PS at the end.  The result does a good job of showing the details in the building thunderheads.  (5D3, 100-400 f4 IS II @ 321 mm, f/16, 1/250s, iso 200, tripod)
