>> I have 27 images, I think it was about 4 rows, and because I took them without using my camera's panorama feature, the camera settings are different for each shot and hence the contrast for each picture is a bit different.

Another one is to use PTblender to export adjustment curves to be used
in photoshop or the gimp.
I have the feeling that some people get confused with the features of
emblend and PTblender
>Enblend "smooths" seems, but does not change brightness or colour in
the original images.
PTblender changes the contrast of the images so they match.
I really think the following process could provide the best results,
but it is time consuming:
1* Export adjustment curves using PTblender
2* Read them in photoshop along with all the layer photographs
3* Adjust manually until they look "close enough"
4* Use enblend to merge the seems.
Ideally, as we have discussed before, what we need is a program that
takes an image and corrects it by a certain number of stops. This will
require per-camera calibration, but it should not be difficult.
In that case the f-stop adjustment would happen _before_ using nona or
