Nice shot Andrew, I think I would try it with a little more contrast to get more impact from the shot. It looks just a bit flat to me.
Maybe crop in a bit more also.
I have taken the liberty of doing this and show you the reults. First shot is levels adjusted to bring the shadows down. second one same plus contrast and brightness brought up. I like the second on best myself, but the first has more shadow and highlight detail. They look like a hard rocking band so a harsh light makes it work for me.
If you are not happy with this and want me to remove these just let me know
Thanks for the comments...its a difficult one because my original idea was to give this very 2006 Rock n Roll band an old worldy feel. however the more I think about it I think you may be right about the adjustments you have made.
The thing is as you say it's a dificult one, there is more than one way to skin a cat as they say.
I was thinking old Rolling Stones type black and white images with lots of contrast and little highlight or shadow detail, common back then. Your photo looks nice like that as I said, but this may be closer to what you originaly intended.
I used uniform monochrome noise at 4.5% to simulate the graininess of the old film. this is close but a bit of experimentation I'm sure would get it better. Had to enlarge to 800 x 600 as it doesn't work on the small image. If you try it on your original you will need a higher percentage if it's a large image.
Ideally you would put more noise in some areas than others, maybe less on his face and a bit more in the shadow at the bottom, which means creating layers and erasing diferent areas to show the others, time consuming but interesting what you can do.
I think both options are nice, just depends what look you want.
