Hey, im driving myself crazy trying to do something, but im asking now if its actually posible.
Id like to make the image black and white like an old movie, thats easy, but the hard part: to make one single color visible.
For example, a black and white preset where only the blood is colored. Im trying nonstop with vibrance, tonemap, but still looks horrid.
The closer I got was the overall image red...sad.
Or tried with DPX and vibrance, I can make it semi-black and white where the blue looks red....thats all I could get, so If i managed to realiza to highlight the reds, it would look in another color :/
