selecting wispy hair questibn

Was watching a tutorial on selections, and the presenter was asked  a question about wispy hair. The presenter quickly answered the question by stating  basically --to use  channels to make an initial selecin ( Iunderstand that)---then paint on the mask in overlay mode .    Can anyone elaborate on"painting on the mask in overalay  mode"y to complete the selection--a link to a tutorial maybe...

I am quite familiar with making  difficult selections- but not totally familiar with this particular technique.

Thanks

Paint overlay is a simple technique and here is the way to do it:

When the selectionis is done and the mask is set, ALT click on the mask and set the foreground color to black. Then select a soft brush and set its blend mode to overlay: now paint all grey parts of the mask and see what happens...whithe is unaffected and all grey parts are now black.

Then ALT click on the mask to retrieve the picture and refine hedges if needed.

This technique to refine details in a mask is called "choking" by some, or "carving" by others. It needs to be done in a little more sophisticated way than just wacking the mask with a 100% black brush.

First, set the overlay brush to low opacity, about 5% to 10%. Set the brush colors to the default black and white. Then make brush strokes by alternating between black and white (press "X" to swap the colors). A white stroke will "choke" or "carve" away some of the detail, a black stroke will add or enhance some of the detail. Basically, you are increasing the contrast of the mask.

With a little practice you can quickly learn the technique and develop the skill to know when to use white vs. black. It's the swapping back and forth that makes the technique useful. It is a destructive technique, so it's a good idea to save copy of the original mask.

When you are painting on a mask it's difficult to see the end result. Here's a tip to use when painting masks.

1. Go to the menu "Windows/Arrange" and make a "New Window for...", then "Tile Vertical" or "Horizontal" as desired.

2. The same image is now displayed in 2 windows. Pick one, alt-click on the mask, and paint away. You get to see the mask in one window and the real image in the other window.

3. If you need to zoom or move the mask window, go back to the "Window/Arrange" menu and do a "Match all".

Thanks, I am familiar  with painting on  a mask(flipping back and forth between black and white) for other things including  smoothing skin---, and am  also accustomed with  painting on a mask in overlay mode- just didn't think of using  those techniques  for wispy hair.

Re: selecting wispy hair questibn

When your making a Mask from a channel copy you  want to leave the whips of hair area alone intact and gray. Only adjust those are with tools like Photoshop filters. You can paint interior and exterior areas Black and White. Leave the whips if hare area alone during this phase of creating a channel to be uses as a layer mask. Once you add it to a layer as a layer mask it time to adjust these areas. You can target the layer mask and use thing like levels and slide the sliders and see the effect the change make on the layer content view.

Now if you want to adjust the mask more its time to paint in overlay mode, Overlay mode protect the current mask Black and White areas. Area that are pure White and Pure Black will not be changed only the gray areas can be altered and as grays become black and white they can not be changed. So you want to use very low opacity Black and White soft paint and make many strokes to adjust the mask slowly. Observe the image content in the image window not the mask view.

When thing are looking good Alt Click on the LAYER Mask in the Layer Palette so it will ne shown in the image window and not the content view. You mah see some areas in the mask you may want to smooth, blu etc.
