I am self-taught in photoshop CS3. I have placed a second image (second layer) on the first image (background). Working in the second layer I reduced the opacity and used the lasso tool to outline the object in the background to cut and paste the second layer, to create a third layer in which I can have varying opacities in in the second and third layers. However photoshop is not allowing me to cut and paste or clear for some reason. Does anyone know how I can remedy this. Thank you for your help.
