  • set the black point/white and gray, help me?

    Hi

    i 'm used sometime to set the black point white and gray

    for the gray , i add a gray layer , blend difference
    after threshold and move the slider on the left (i guess it's right , move the slider on right sould be a mistake ,shouldn't ?)
    and so i find the gray point

    a question about the black and white point
    i work only with photo
    i guess the value 000000 for black an ffffff for white , are not natural

    which values do you use ?

    thanks
    cheers

    For RGB try 245 for white and 10 for black.

      Recolouring - White to Black
      by Aleria
      I'm very much a novice at this kind of thing, but I've been trying to turn a white object black... tried all the tutorials and suggestions I could find, but still can't do it without losing all the definition.
      I use Photoshop Elements, so I'm probably missing a few features.
