B&W High Contrastby
acrotideComment: First, thanks for the terrific explanation and links to the other shots! That's a terrific tool for helping others follow along.
I think this particular photo is a great example of what the various versions do for you. Of course, you start from a nicely composed, nicely exposed, nicely focused shot. Let's not forget the fundamentals here.
Here's my reaction to each shot:
Color: an old barn, but not especially decrepit. It's a nice day, enjoying some time in the country. Emotion: calm, happiness, generally enjoying life. It might benefit from some higher contrast, but not to extremes. Details I'm drawn to: the shape of the barn against the sky, a little texture in the barn, the hay bales.
Initial B&W: kind of bland; while in the color version the sky contrasted with the barn and the ground, here they all kind of blend together. Emotions: tired, end of day, ready to go home. I notice the sky darkening in a way I didn't in the original, which suggests the end of the day to me. I realize intellectually that it's just the usual sky lightening near the horizon, but emotionally, that's the effect. Details I'm drawn to: not much, actually. Mostly the shadow line under the roof.
High contrast B&W: ZAP! I immediately zoom in on the textures in the wood, the way the loft door stands out against the grain, and how the main door is falling off its hinges. The sky seems ominous now. The hay bales fade out of view. The barn's upper wood stands out against the lower stones. I wonder what's hidden in that shadow on the left and over in the very dark woods. Emotions: a little afraid, like the barn's probably haunted. And the sky makes me worry a storm's coming. Finally I feel a little sad for this barn that's falling apart.
I'm not saying the high contrast version is better than the color version, necessarily. It just conveys different things, and the high contrast version affects me more strongly. The initial B&W is definitely the "tamest" of the three, and wouldn't hold my interest for very long.
