I'm trying to turn a colour photograph (It's of the Forth Rail Bridge in Scotland) into a Black & White one however… having done that, I want to bring back some of the red parts of the bridge. I would also like to do this 'Dash of Red' in other photographs too perhaps even some where there wasn't any red in the original colour photograph. Is this possible and what is the best way to proceed? - Much'O Thanks for any help given. ~
