Isolating the prominent object and removing the background?

It depends on how subtle the differences are between the background and the object. If the differences are blatent, it is quite easy. The magic wand tool will select a group of pixils based on similar shades. You can hold the shift key down as you are selecting areas within the object and the selections will group together. Once your entire object is selected, you can cut it out or invert the selection and replace the background with a new color. Similarly, you could use the magic wand tool to select the background vs. the object and then invert the selection to get the object. Such object selection is much easier when a constant color is used it the background. This is why Hollywood uses blue screens for filming scenes that have CG animation effects. The background acts as the only layer in which animation can be drawn. This is how layer masks are used.

Hope that helps.

Is there a feature in Photoshop to isolate just the object in front/center/of interest, so that the background and surrounding are gone. Is this called chroma keying? Does anyone know about this and is it possible in PhotoShop7?
Many Thanks,

Many Thanks for your reply. I will give it my best effort to do as you described. The problem is that backgrounds are landscapes and not a consistent color, but I will see if I can make this technique work.

The problem now is sifting through all the PS7 menus to determine which feature will best apply to accomplish this effect.

You might try the "Extract" command in the Filter toolbar.
