Photoshop Elements
1) Selectively sharpened the loving couple and the top of the flower.
2) Selectively blurred the lower part of the plant.
3) Lightening up the picture +12
4) Saturation of red increased +36, as usually done in sex movies - ;)
Best regards, Peter.
I noticed a fair amount of luminance headroom and thought bumping the levels would add some drama to the shot. Cropped a bit closer and cloned out the white object in lower right.
