changing color of hair?

Discussion in 'Photoshop Tutorials' started by Gaikokujin Kyofushso, Oct 26, 2004.

  1. Hi, I am trying to figure out how to realisticly change the color of
    hair in a photo. I would like to change this guys light brown hair to
    dark black (like Asian). I have played around with selective color
    adjusting, masking, etc but can't seem to get the right effect. Any
    help would be greatly appreciated!

    Cheers

    Maybe a dark brown soft-edged brush on color mode, low transparency,
    multiple strokes being careful to not stray 'outside the lines'. Can get
    some more contrast into the hair by burning shadows and dodging highlights
    too...

    Great for tarting up your mates!!

    in CS use the colour replacement tool

    in v7 select area, copy to new layer, use Select menu > colour range,
    adjust the opacity.

    There is a tutorial about adding colour to a black & white image here, but
    it may be useful for changing hair colour (you would presumably have to
    desaturate the selected hair first!!)

    There are also a wealth of other tutorials you may find useful?

    Humm, turning a blond into a brunette or darker - sounds like another
    plug-in I should develop. I will call it "Adding Artificial Intelligence".

    The name is too long, it'll never sell. How about "IQ++" ?

    Let me know when you get "Couth++" working. I have a couple candidates
    in mind...

  14. It is difficult to be very specific. This type of "adjustment" is
    feasible, but usually takes a bit of "playing around." Since you
    posted this to one of the photoshop groups, I'm assuming you are using
    that program.

    The first task is to isolate the hair from the rest of the photo.
    There are quite a few ways to do this in Photoshop. My general
    approach would be to duplicate the image to a new layer and create a
    layer mask to hide everything on the new layer except the hair. Then I
    would change the hair color on the new layer.

    Creating the mask will be the most challenging part. Again, there are
    a bunch of ways to approach this. The most successful will depend on
    the photo and perhaps your patience and skill.

    As alternative, you might try duplicating the photo to a new layer and
    using the extraction filter to remove everything on the new layer
    except the hair. If that gets you pretty close, you can clean up the
    new layer using the history tool and eraser and then manipulate the
    hair color on the new layer.

    Good luck,

    Simple make a mask to select just the hair, make sure the mask is made
    using a soft brush and then just use Hue/Saturation (Adjustment Layer)
    to choose a color. Now use a Curve (Adjusment Layer) to set the
    lighting. Finally Color Balance (Adjusment Layer) and set the color.
    Make sure all the Adjustment layers have the 'hair' mask.
    It's as simple as that :)

    Taking a slightly lateral approach, can you take a different/new
    photo? If so, take him against a uniform colour background and
    it will be a snap to isolate him from the background. Then you
    can paste him on whatever you want.

    There are two issues - the one you seem to be having problems with is the
    most common one, the masking. There are several techniques for dealing with
    this. If you haven't tried the Extract tool, now is the time. There is a
    good tutorial at www.myjanee.com, and Dr Brown at
    http://www.russellbrown.com also has a good video tutorial.

    Another method that works well if you have a contrasting color behind the
    hair is to use either the a or b channel of Lab as a mask - use levels to
    see which of the two is better. For that matter, check all the channels:
    r,g,b,c,m,y,k,l,a, and b for the best mask, remembering that you have any
    number of cmyk channels depending on your gcr / ucr settings. The
    curvemeister demo is a fast source for these channels, using the copy
    channel command, which is 100% functional in the demo.

    Another technique is to painstakingly paint the mask - this is done often
    for glossy ads, and although great skill is required, it remains the best,
    final, way to get a mask.

    Once you have your mask, the second problem is getting realistic colors.
    Brown hair has warm highlights. Black hair, particularly Asian hair, has
    cold highlights. Getting this to look "realistic", as you say, is probably
    going to be even more difficult than the original mask, but requiring an
    aesthetic judgement rather than technical expertise.

    Which is why some have suggested that you take a more direct approach of
    cloning hair from another image. Or pose someone with hair similar to what
    you want, pick a contrasting background, duplicate the lighting, and simply
    add the hair in a single operation. This seems like a lot of work, but in
    the end it will be easier, and yield a much more convincing result.
