Hi Rene,
I did experiment a little. I divided image in two layers, one is fisherman with the boat and other surroundings. I did darkened the background, disaturated it a little and added some gausian blur to get more contrast between the forest and fisherman. I darkened and disatureted fisherman too, gave him some sharpnes but not too much to avoid noise due to low quality and finally added frame. I hope you llike it.
Best regards,
Jeri
