Rather than fine tuning lots of tiles, when ghosting is present on overlapping images, is it possible to simply DELETE parts of either the overlapping image from the left picture or right picture? Say there is a 80% overlap, why bother trying to fine tune all the overlap, when only say 10% of the overlap is really needed?
Because Panorama Factory insists that all pictures be of equal size, I can not simply go into Photoshop and delete that part of the image that I do not want to overlap. Is this what the trimming function in Panorama Factory is for?
Rather than tuning the overlap, it seems to me that the best possible strategy is to MINIMIZE as much of the overlap as possible that is unneeded.

You can control the part of the overlap region that is used for blending the images by simply dragging the boundaries of the blending rectangle to the left or right.
Depending on the cause of the ghosting, this may or may not be useful in correcting the problem. I find that sometimes you have to use both techniques -- fine tuning and adjusting the blending boundaries.
Sometimes an overlap region will have a ghost you just canít eliminate with fine tuning. If an object (e.g. car or person) moved between the times you made the two photographs, its position and/or size will differ in the two images. Thereís really no way to adjust the images so that features like this will align sharply. You can sometimes eliminate these ghosts by adjusting the boundaries of the blend region.
You make these adjustments when you are looking at the entire stitched image--after double-clicking the thumbnail for the "stitched" image. The overlap regions are displayed as rectangles. Move the cursor over a side of the overlap region that has the ghost. The cursor changes to a double-headed arrow to indicate that dragging will change the width of the rectangle.
You can include or exclude portions of the lefthand image from the blending region by moving the left edge of the rectangle. You can include or exclude portions of the righthand image by moving the other edge. You cannot, however, enlarge the rectangle beyond the boundaries of the image overlap. If you try, the rectangle edges will snap back.
The trimming function is for removing parts of the image file that are outside the image itself. This is mainly useful when stitching from scanned images. For example, if you scan a negative, slide or print, the scanned image may include the blank frame around the image. The trimming function is used to eliminate this extra frame and make all images the same size. This tool is not really applicable when stitching images from a digital camera because they do not include an image frame.
I hope this helps!
