image? I'm trying to adjust the levels of a photo but there are two small areas that I want to stay as is. I can't seem to lasso around both so that I can then inverse and adjust levels on the non selected area.

I think by default the selection is that each time you select something, the previous selection disappears... try using the addtive function of the lasso. The lasso tool can also be a negative (at least in Photoshop CS2), so you can select your entire image, then select the negative lasso and remove the spots that you want to stay "as is"

hold down shift as you are choosing the next spot. That will select both areas then you can do an inverse selection.

That did it. Thanks so much.

Or, make sure you are lassoing in the correct mode. See the illustration below and note that there are 4 selection modes. Right now the "Normal" selection mode is turned on . It will select something then if you select something else, it will "forget" the first selection and go to the second one.
Then (next moving to the right) is the "Additive" mode [icon looks like 2 overlapping boxes]. With this mode it will remember the first selection and add the second selection to it.
Then is the "Subtractive" mode. [icon looks like one box taking a bite out of the one behind it]. With this mode you can [I]deselect part of the selection. I use this a lot to "fine tune" my selections.
Finally, there is the "Intersection" mode [4th icon of 4]. With this mode, you can select 1 area then another area that overlaps and the program will keep only the areas occupied by both selections as active.
Hope that helps.

Good grief. This is basic.
Use a Levels adjustment layer and paint black over wherever you want to be not affected.
Adjustment layers come with a built-in mask. All you have to do is add it, make your adjustment, then after you have OK'd out of Levels, use the paintbrush (soft brush) and paint with black (directly on the image; make sure your Levels adjustment layer is still selected in Layers) to remove the effect (the adjustment) from anywhere on the image. One place, a hundred places, use the gradient to make a smooth transition, you name it, you can do it with a mask. On a mask, black = remove; white = apply; gray = apply in proportion to the darkness/lightness of the gray.
If you want the Levels adjustment to affect only the layer directly below it, use Create Clipping Mask (in early versions of Photoshop, that would be Group With) found in the Layers menu.

If I understand your question correctly and I didnt' see this response in the replies you may want to identiy and use the toggle buttons on the button row that appears when you use any selection tool. Look for the 4 button labeled:
new selecton
add to selection
subtrast from selection
intersects with selection
