Thanks for all your techniques and the link. I'm experimenting and although i'm still a little slow, i'm getting the hang of it.

Re: Precisely Cutting out images from Photographs.

I use the pen tool to draw around the object I want to keep; then right click with the pen tool over the object, choose "Make Selection." Then click Select tab, inverse, and press delete. The background will then disappear.

However, do make a duplicate layer before doing this in case you have to start over. Just turn off viewing for the duped layer when you do your cut.

Re: Precisely Cutting out images from Photographs.

if you have CS3 check youtube for tutorials on the extraction filter. Ive used it with excellent success.

You can do some amazing things with the extraction filter! Even in CS4 (which doesn't ship with the extraction filter), you can download it from Adobe (it's an 8Bf format filter) and use it in CS4.

Re: Precisely Cutting out images from Photographs.

You have several ways to acomplish extraction which fits with several type of images for extraction. Sometimes a mix between techniques is needed.

For geometric objects (i.e. bottles, chairs) you could use even the magic eraser tool or the background eraser tool (E or Shift E to cycle). This tool works perfectly with flat backgrounds. For non flat backgrounds better the pen tool and do a clipping path.

If the object is placed in some noisy background, but the object itself is plain/flat and simple in texture, you can choose extracting the background instead the object (inverse procedure).

You can also use the color range thing (select/color range) after applying it, you just need to erase for the result what you don't want part of the selection or what you want by using other selection tools such the Lazo (L or shift L to cycle) or Magnetic Lazo/Poligonal Lazo tool for cleaneing. Once selection is done, feathering it with select/modify. If you have CS4 just load up the selection into a Mask and perform select/refine edge.

Or you can use the hardest way (for organic objects such hair, clotes and even transparent things such bottles, smoke, water (the hell of hard), which is using alfa channels and channels (some people use calculations also). Go to Dr. Brown website, he has an excellent tutorial about this.
