Thunderheads in the evening, Afton MN

Tripod mount, ND Grad to equalize the field with the much brighter clouds. Hard edge ND grad was used, the area of transition is from the horizon to the flat bottom of the Thunderheads (the color transition in the white clouds was a natural effect of the sun setting). Manually metered to get best match, bracketed. PhotoShop: Curves and Minor Saturation boost.
