Re: Hair -cut out

Hey Jonas,
If you have the time to do a quick video that would really help....I am a bit of a visual learner. If not then dont worry I will play around. Really appreciate the time spent on this.
Marc

Re: Hair -cut out

Hey Marc,

I put up a video on YouTube (if you want me to, I can remove it of course): http://www.youtube.com/watch?v=iI56N3PKTMo (quality is pretty bad unfortunately, hope you still can see it :-)?)
And of course here's the PSD-file if necessary: http://www.sendspace.com/file/z5ynyb

Btw., you're not restricted to using "Soft Light", but anything harsher (like "Overlay", "Hard Light" etc.) will require a bit of a better mask ;-).

PS: Excuse my pretty slow computer. I guess that comes from copying about 200GB from one hard disk to the another while recording Photoshop ;-).

Re: Hair -cut out

Marc, the blue overlay was only meant to highlight the hair for visualization. I rarely need to place cut-outs on a solid color but usually into a new complex background.
The blend if sliders can often be used effectively to mask off the hair which is usually the most tricky part of the extraction. You can use the Blend-If on a copy of the background with the background turned off. That will give you my 1st attachment. You can create a merged layer, select the hair / head and save as an alpha channel. The rest of the body has a well defined edge and can be selected with the quick select tool or pen tool or any one of a number of other tools and that selection can then be saved with the option of adding it to the previous alpha channel - so you have a full cutout.
BTW, this will alos work on white BGs or other color BGs but you will just change the way you position the slider or you may need to use one or more of the color channels instead of the gray. Blend-If sliders are often forgotten about or ignored but they can be very valuable masking assistants.
Regards, Murray

Re: Hair -cut out

Hi I'm not a professional retoucher, but how I'll do it.
1-Use the derW method to obtain a transparent background,
then make a blank new layer, fill it with white, merge these 2 layers.
2-go to the channel panel and choose the most contrasted one , dupe it.
3-go to image>adjustment curves (or whatever) to increase the contrast of the channel
4-take a brush, quite big, and paint over the inside of your subjet avoiding edges and tricky parts (eg: hair) in black (you're still on a channel).
5-refine your painting for the edges with a smaller, harder brush, still avoidind tricky stuff.
6-change the blending mode of your brush (was initially "normal") and set to Overlay- paint over the hair...the overlay mode increases the contrast, leaving the white background untouched (that why you wanted a white background at the 1st place)
7-ctrl click your channel (or click on the selection icon to produce a selection from your channel.
8-transform your selection into a mask attached to your original image.
you can now delete all the other layers...
9- you got to invert your mask but before you can refine it directing by painting Black or white on it.


But you pros may want to simplify my ways...

Re: Hair -cut out

This one is way more though, overlay masking probably won't work for satisfactory results!

You could however try to use the black and white adj. layer with all the colors set to -200 to get a (inverted) starting base.
Or use a saturation mask (might be even better suited), by creating a new Selective Color adj. layer, setting method to be "Absolute" (in the adj. layer, not in the layer's blending modes), pull the blacks of all colors to -100% and the blacks of the neutrals to +100%.

Now proceed, as you would with any channel based mask.
