Could someone direct me to a tutorial or lesson where I can figure this out?

I have an image of an eyeglasses wearer where I want to replace the background. The eyeglasses wearer has his head turned somewhat to away from the camera and I need to extract the person AND replace the background BEHING (as seen through) the eyeglasses.

I'm stumped so far but I have seen it done so I figure there is hope.

try the magnetic pen tool.

Thanks, but the problem is not the selecting of the eyeglasses it is maintaining the transparency so I can change the background as see THROUGH the eyeglasses.
 
The "see through" area is where I'm suggesting using the pen tool. Maybe move it to a new layer and lower the opacity. If you post a picture of both the glasses and the background you will get many suggestions. It is hard to give specific advice without seeing it...what works on one picture might not on the next.

All you need to do is extract the background from the glasses...use the pen tool, magic wand, etc. and clean it up if needed.
a quick and dirty way
move him to the new background
use the magic wand and invert the selection
Click Add Vector mask
Clean up mask.

Ypu will have to hand paint some reflections and some deformed background shape to make it look nice. To do it easily, but not perfect, keep the reflections and the yellow/red box on the right glass untouched. After addin the new bg paint on the yellow/red, changing its color and loosing the detail, but not the outline, trying to make it look like a part of the new bg being deformed in the glasses. It is a very weird deformation but looks 100% real so leave it there.

In general to mask halft-transparent objects the way to go is getting the mask from a channel. What you need is a mask with opacity less than 100%, depending on how opaque the glassses are. In this case where tha glasses are almost tranparent, you could easily get away with a light tint on the bg that show through (I would use very light yellowish color, maybe with a little purple). And of course don't forget the reflections. Even if they are not there in the original photo you should aertificialy create one or two highlights on the glasses.

Select a piece of the new background a little larger than the eyeglass lens. Copy that piece, paste it on a new layer and move it so it covers the lens. Mask that piece out entirely, then paint it back in where it would show through the lens. This way, you don't have to do any extracting.

you ould use knockout 2 for that, it retains transparency. Also mask pro 3 can do transparency masks.

Created image in Red/Blue/green channels to create mask. Used green channel, created mask, tweaked mask, histogram adjustment, high pass sharpening, noise removal. Added background and darkened it for better contrast......Ralph

 
Yes - I admit I was fuzzy on the concept.

You've helped be understand this and because of you kindness I had an image for that gentleman's b'day party tonnight. I was a nice surpise for him.

Thanks again for your help, and yes heather551 I admit I am a moron and I will take your reminder to heart.
