Pano no.3
This is the beginning file with all the layers in order and over lapped.

This is after blending. On this image i only had to use layer masks and did not have to change the levels or brightness between them as they were all the same. So all i did was blend.

This is after i cut and swapped the ends around. Again because I didn't change the levels at all the ends matched up nicely just needing me to blend the edges in.
This is a section of my finished Panorama:
Pano no.4This is my starting file. There is quite a bit of colour difference in the middle because i was a bit close to the tree i turned the flash off as not to have a major difference.

This is after blending. I found some difficulty matching the ground and fallen leaves as when i tried to blend the layers it made it look blurry.

This is after i have swapped the ends around. I found that this bit was actually the easiest bit to match and blend. Again i didn't have to change the levels at all so the ends matched easily.

This is a screen shot of the final panorama:
