My choices are 6-8 and the right side image of 6e800.
On 6-8, I like the color and the areas of selective focus. I like that the blur is lens blur and not motion blur. When it comes to close up portraits like this, I find motion blur a bit distracting but freely admit I tend to be alone in this thought. This why I like this image over the left image in 6e800. That image has some motion blur to the right side of the face.
On right side of 6e800, I prefer this image to the color one for a few reasons. The black and white and style of processing gives the image a harder edge or rather a feeling of discomfort maybe? Like things arent going well and considering the problem he has, I find this image very moving and really, is my first choice all the way around because of the emotion I see in it.
The other, color image like this has a much softer feeling. He looks serene and meditative. I also find the curtain in the background a little distracting in this image where I dont feel that at all in the black and white. I suppose its because in the second one I can see more of it in the b&w. It is a tough call for me though, between the two. I really love them both very much. I think the b&w speaks to me more because of that over all troubling feeling I get from it, like Im seeing somebody who is facing something tough.
The last one is an almost playful spin on the other two and I like that as well. Its a totally different feeling for me. They all have completely different feelings for me. The last one is almost a Mona Lisa kind feeling, like he knows something I dont and is showing that with a smile in his eyes.
Like I said, I love them all. These are all beautiful portraits, but my heart goes out to that small b&w most.
