Below are a few variations
on the same image, thanks to Photoshop. Not the difference in
textures and shades between each of these photos.
1. Photograph as taken. (I've not used
Photoshop to remove the colour from the man. He was a grey man when
I photographed him!)
2. 'Poster Edges' filter applied to 1. above.
3. 'Diffuse' filter filter applied to 1.
4. 'Diffuse Glow' filter applied to 1.
