Could someone show me a tutorial on how to blend images in Photoshop?

I'm pretty Photoshop savvy, except for the fact that I've never learned how to really blend. I love creating graphic designs and have always wanted to know how to blend, so i could make things like these:

and etc... So if anyone could please send me a decent tutorial, or explain to me themselves how to make blends such as the ones above, I would be very grateful!





P.S. I have Photoshop CS4

You can also layer images and use the eraser set to 0% hardness and erase around the image. You'll have better control this way.
