Isolating the prominent object and removing the background?

    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,
    Marina

    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.

    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.
