3 pictures, 3 different black and white conversions...

I think I want to change the way I do black and white pictures. I have done them one way for a while and now I'm looking for something new. So, here I have one little girl (Maggie - isn't she adorable?), 3 different pictures, 3 different styles. Yes, I realized as I started typing this that I should have tried each conversion on the *same* picture; but I need to get to bed. So, I'll do this today and maybe later this week I'll come back and post with all the same picture. For now though, let me know which you like best. The first is more of a true black and white. The second has a bit of a warm tone to it. The third has a bit of a chocolate tone to it. I know my husband will say, "Um, I don't see a difference." But if you do see a difference let me know what you think. If you don't see a difference, let me know that too. ;-)
