Unfortunately, I haven't been able to take the camera out recently (work, mortgage, car payments, damn life stuff). I've got one day to go though, so maybe I'll be able to take it out tomorrow, fingers crosses. In the interim, I've gone through and made black and white conversions of some of my old color shots.
I found this to be a really fun exercise, if you've got some old RAW files laying around I'd say it's worth seeing what they would look like in black and white. Now the Soldier shots I think do look better in color, however, the landscape, I think I like that in black and white more. The colors are included below for comparison.
