  1. great tutorial..but I wonder about “then create a new layer then use “history brush tool”” .. where I have to create the new layer? over all the others or in between them?

    thanks :)

  2. I’d like the same information as Max, The beginning of this is really easy to understand, but I get lost at the 4-5 steps, what is the purpose of the adjustment levels and the eyedropper? Also how do I change the layer mode to screen?

  3. Hi reanelaw. Result of ur method are definitely better than lasso tool method. But I cudn’t follow after step 4.

  4. i could not follow too after step. can anyone help me i have to photos with black background. i want to change into white!

  5. Layer 1 set as screen mode (in LAYERS…you will see the box below the LAYER text together with the opacity and fill…its always set as NORMAL…just change it in SCREEN) then create a new layer where you can trace the outline of your image…if your done tracing, click the eye of the layer 1 then you will see the outcome of your work!
