Just take all your images and do your stacking and minor waveletting, then use autostitch.. there's nothing to know, just open the files and it does it.
Then do your final post-processing on the combined image.
the only thing i wished autostich did is keep the origial file sizes.. not reduce the image down.... I think i will have to do it in Photoshop, because i want to do a larger print out of these.
striker - even you can use autostich.. you choose what piccies you want stiched together and the program figures out the rest... ohh and when u do 1 piccie make sure u rename it otherwise when u do the next pic it will write over your first piccy!
Rowena you can get the original size by going into the options and selecting 100% for the size, though if your computers not up to the task it may choke during the process. I just set the width and height of the finished product to 3072 by 2048, the standard 300D large fine setting. And also set your jpeg quality to the degree you want in the bottom left hand corner.
