In my photo, I want to have a portion of it transition from its captured color to B&W. I can't seem to accomplish this by using a layer that has been converted to B&W and had a layer mask applied to mask out the portions that I don't want to have the transition, and underneath this layer is the normal (colored) layer with no mask. If I could add a second mask to the top layer to add a gradient, it seems that would get me the result, but it appears only one mask per layer is allowed.

Any suggestions??

Like idad said. Use a B&W adjustment layer and apply a black to white gradient to the mask.

Not sure I described this well enough. See attached screen shot.

I want the dirt to transition to B&W as it progesses to the background, i.e., the foregd portion (bottom of image) should have full color but the backgd (top of dirt) should be B&W.

Not quite. I want the dirt area at the top to be B&W, the dirt area at the bottom to be colored, and the transition to occur between the top and bottom.

Select the dirt. Copy and paste it to a new layer. Convert that layer to B&W, then add a layer mask and use the gradient tool set to black and white to reveal the amount you want.
