I've been trying to get this pano' for over three weeks now driving up into Canyonlands N.P every night. So last night when I thought I'd got something interesting I was excited to put it together on the computer. Unfortunately there is a series of grey vertical shadows running down the left side of the image and I don't know why.
I shot the image on a NN5 with the RD16 rotator set to 10 degrees. There is probably about a quarter overlap, I don't know if I have too little overlap.
The image was shot with a Canon 5DMKII with a 24-105mm lens set at 105mm. The camera was set on the upper rail to 64mm as recommended on the NN site. I've tried to stitching this in Photoshop CS4 and Ptgui to the same effect.
The camera was set to manual focus and all exposures were identical.
I would have thought that if my problem were caused by insufficient overlap then I would see this vertical shadowing throughout the image and not just on one side.
One other thing
I've just remembered that might be worth noting. I forgot to remove my polariser, maybe this could be to blame.
I would very much appreciate some feedback on this.
Many thanks Andrew Waddington
