Lasso Tool

Okay, something I've tried multiple times to do but never succeeded in is outlining part of a photo in order to impose it into another photo.

Say I wanted to take the woman on the right in this photo - http://sweetestgoodbyes.org/gallery/albums/uploads/GH/Stills/Nov08/normal_114590_4150_ful.jpg - and put her on top of herself in this photo - http://sweetestgoodbyes.org/gallery/albums/uploads/GH/Stills/Nov08/normal_114590_4151_ful.jpg

I read somewhere that I should use the magnetic lasso tool but when I try it never works smoothly!!! I always end up cutting of half of someone's head or something.

Any help with this situation would be greatly appreciated. My ability to manipulate photos is restricted to using the cloning stamp and I would really like to expand my repertoire.

Maybe this would be a good technique for a tutorial ...
 
There are hundreds of tuts outhere. You will learn that the best way is heavilly depending on the picture in question. Generally speaking, using the pen tool or the "Channels method" gives the best outcome. The magnetic lasso tool is perfect for well defined edges, but fails in complex areas like hair or leaves on a tree.

Can you suggest a good tutorial? I know there is a pen tool, but I've never tried using it. I'll have to see what I can figure out on my own. And what is the "channels method"? I've never heard of that before!

Thanks for taking the time to help me! - shelby
 
Hi I have another lasso query. I want to start a selection using say, polygonal lasso, then interchange to magnetic in the same selection. Also is it possible to change properties eg feather or anti aliased of part of a selection but not all??? Am i for asking too much??

Cheers.
 
You can "interchange", in Photoshop is called: add.
You can select, change the tool and add to the previous selection (choose the appropriate method in the options bar buttons or press shift to add to the selection).
It is only possible to change properties to the whole selection.
You can, however, select an area, change whatever you like, select another area do the same, and so on...

So, I took the two photos above and imposed the woman on the left from the second photo onto the first photo. Here's the result: http://www.mediafire.com/imgbnc.php/e73d2255013f8081708c65d7126aefd44g.jpg

I know this is about the simplest thing to have done with the pen tool, but it was my first try. I googled "photoshop pen tool tutorial" and followed the results to this site: How to use Photoshop's Pen Tool - Online Tutorial at Melissa Clifton page 1 I found it helpful for explaining the basics and at the bottom of the page links to further explanations are provided to help become more proficient.
