@wakelys I use LightRoom to edit my photos. After I converted this into B&W I used the paint brush tool to "paint" the coffee can and in the commands for the brush tool I increased the green slider to color that area. The computer recognized some green in the branches behind the coffee can too, I did the same thing only in reverse. I brushed the branches and took the saturation slider all the way to the left to decrease the color. Good luck! I like this effect in B&W.
You're off to a great start with it. SC can get overused or become trite with the wrong picture. But in this one it works really well. It's as if the coffee can is trying to hang on to life when the building around it is falling apart.
