about 7pm in between thunder storms. i saw this and ran out to the field behind the house. a fleeting moment to say the least. nothing cloned out besides the seam of the composite overlay, and a couple sensor dust spots.
a composite of two photos - both taken at 18mm. working with a rainbow is not easy.
a layer mask for the rainbow in saturation mode - a layer mask for the sky was burned and dodged in luminosity mode - a layer mask for the green area was slightly desaturated.
