For trial runs to verify if the stitching is going to be OK:
Simply reduce the output size and/or JPEG quality
The lower the output size the faster the stitching process will be.
Gain Compensation: Selecting gain compensation causes AutoStitch to modify the brightness of the images so that they are consistent with each other. This causes dark images to become brighter and bright images to become darker.
