That's not a paint effect or post-processing. That's using the full telephoto of the H5 to look into the distorted waves of heat radiating up from the hot sand and saturated air on a late Florida summer day (our summers run long down here!). Temperature was hovering just near 100 degrees, with humidity at 90%. Mr. sweaty was still getting his exercise, while my hot, tired, lazy butt sat on the beach and snapped photos!
