Sometimes when I stich the images, some parts don't match together. What is the best way to correct this problem, or is there a trick to get them stitch correctly the first time?
This issue can arise from a number of different issues so depending on what caused the alignement issue would directly impact the remedy. The fist attempt should be to edit your matching points within PW. If that will not correct the issue you proably have a bigger issue such as a nodal point being off badly. We would need to see some examples. Hope this helps.
