 Using Photoshop with masks
Adjusting seam locations and removing ghosts is easy when your panorama is saved in the Photoshop with masks format. This tutorial shows how the bottom photo in the "creating a cubic/spherical panoramas from fisheye images" tutorial can be adjusted by painting on its mask layer to hide or reveal image area.

Clicking on an 'eye' of the layers pallet toggles a layer's visibility on and off. For this example, we are showing what the panorama looks like with the bottom (nadir) image on and off. Layers are arranged such that the bottom layer on the list (L01 in this case) is also the rear most layer in the image.
Next, we click on the small black and white thumbnail for layer LO5 making the mask layer for layer L05 the active layer or mask. An easy way to see which layer or layer mask is active is to look at the image thumbnails on the layers pallet. The active layer or mask will have a double line around it. For this example, we make the layer L04 mask layer so we can paint the mask to either reveal or hide L04 image area.
The paint brush is activated by clicking on it and the brush color is set to black. Painting a mask black hides the image in the layer while painting the mask white reveals the image.
The airbrush brush style works best in most situations as it gives a nice feathering between the images. For this example, we set the brush diameter to 17 pixels because we are working with a very small panorama. Increase the size of the brush for larger panoramas to get the seam width that works for your situation. Brush mode is normal and opacity and flow are set to 100%.
We are now ready to paint the mask of the bottom to hide the legs and shadow of the photographer. Remember, painting a mask in black hides the selected image layer and painting in white reveals image. A bit too much mask is painted in our example which reveals a blank area in the panorama. This shows up as a small white area. We fix this mistake by changing the paint brush color to white and painting the image mask to reveal the underlying image. You can toggle paint brush colors by clicking on the inkwell or by pressing "x" on your keyboard.
Finally, option + clicking on layer L05's mask thumbnail reveals how our painting changed the mask. Clicking on L05's image thumbnail shows the panorama and clicking on the "eye" toggles the visibility of the entire layer.
