    O.k. I am sure this is a simple one for the real PS heads. I was wondering if there is a simple way to select a certain area with the lasso tool instead of tediously tracing around the subject you are trying to select. I guess it would help to tell what I am trying to do so if there is a different way some can help with that. I would like to pick out certain areas to do levels correction on differently that the rest of the image. I hope this is clear enough of a question.

    There is the magnetic lasso...which snaps to areas of high contrast.
    You could also try using the magic wand to select areas, or using the 'select/color range'.

    A lot of times I use the lasso or magic wand to get a quick & dirty selection...then use either a mask (or quick mask mode) and use the paintbrush to do the tedious parts of the selection.

    Easiest way to do selective levels adjustment is layer mask, then use black and white brushes. Black conceals, white reveals.

    I like the Polygonal Lasso for most selections, unless the area is simple and distinct enough to use the Magic Wand.

    Also, if you're selecting more than one specific area, just hold down Shift as you begin the next selection, and the next ... etc.

    Then I use Quick Mask to clean up, before copying the selection(s) to a new layer and doing whatever I want with them.

    Another good tip for selections is to use an adjustment layer...levels or contrast etc. Crank the contrast way up, so that the edges are more pronounced and easily detected by the lasso or magic wand.
    Once you have the selection, just trash the adjustment layer.

    That is a great tip!

    What I do is use the regular lasso tool, but select a low enough feather setting, so I can get close to the edges. Once I have a basic selection, I zoom in to the different areas that need refining and I hold down the Alt key to subtract little areas, or hold down the Shift key to add little areas. Once you practice a bit, you get pretty fluent at it.
