Making fake hairs after cutting and pasting

I do a lot of stuff with a group that edits people's pix for them. A lot of this involves cutting and pasting head-and-shoulders into new backgrounds. I try and make the hair more realistic by:
creating a new layer
picking up the hair colour from the bottom layer
going back to the new layer and with a 1 pixel brush painting new hairs over the boundary between hair and new background.
I then usually put a slight blur on the new hairs, and lower the opacity of the layer a bit.

The end result is often 'good enough' to make the hair look realistic.

My problem is that a lot of the pix submitted to this group are a small size - maybe 900x600 pixels or similar. With these pix the 1 pixel brush 'hairs' look big and crude, even with the blurring/lowered opacity. I'm wondering if anyone has any tip about how I could improve this. (Or any other suggestions re this method...)

I attach an example of this bad hair (with a smiley face for privacy...)

Re: Making fake hairs after cutting and pasting

Some time ago, someone posted links to brush presets for Photoshop meant exactly for that purpose.

Try a search for "brush pre-sets" and see what you get.

Re: Making fake hairs after cutting and pasting

Why not try to smudge the edges a bit?

Thank you. I googled brush pre-sets (hair), but couldn't see anything specific to this problem.

I did however come up with a very good tutorial about creating hair from scratch, which gives excellent tips about making realistic stray hairs. I have been obviously been way too simplistic in how I have done them so far, and need to rethink my whole approach.

The tutorial looks excellent, and I'm sure I will learn lots from it

http://faefolk.com/Tutorials/hairpaintdfh1.htm

Brushes that did the job would be absolutely fantastic. I am going to have a bit more of a search for some.

Thank you for that suggestion. Yes, I think smudging will be part of it, also (as the tutorial above suggests), rubbing out the ends of the hairs with a large soft eraser brush - just using the soft outer edge of the brush to very gently erase...

Re: Making fake hairs after cutting and pasting

When the 1 pixel brush is too large for hair, sometimes I give the layer with the new hair strands a slight blur, then run the maximum filter on it. Sometimes this works just fine and gives it a lot more realism, sometimes it doesn't.

Re: Making fake hairs after cutting and pasting

amica999 - thank you!!! In case anyone else is interested, here is the link for sarsa, and another smudge brush as well.

I will experiment!

anitap - Thank you too. I'm not sure what you mean by the maximum filter? I use CS2.

Re: Making fake hairs after cutting and pasting

I hope this shows up okay, it's a very small image.

It shows part of a head of hair, with 1 pixel brush strokes pulled out of it. Above the line I have used a regular basic hard brush. Below the line I have used a sarsa brush. I think the difference is fantastic. The sarsa brush is miles more subtle than the basic brush.

It will be incredibly useful :-)

Re: Making fake hairs after cutting and pasting

don't smudge hair....hair has texture.
