I lose my bet... No vignetting is visible between rows because this overlap is much larger:

Ok, I understand, the overlap is large enough on vertical rows, so NN5 is not enough for the 300mm (I am at the minimum angle = 3,75°) so it does not overlap enough horizontally......

Now I have a .lcp file for that lens, I have tried it trough the plug in in APG, it does not seem to work very well : the left down corner of the photo becomes all over exposed. So I am going to try the correction directly through PS CS5.

ask Julian Kalmar (Vienna 60GPx pano) - he had a ring custom-made for tighter steps on NN5.

Did you try the pictures completely un-processed?

Perhaps you should go for a Merlin/Panogear robotic pano system had for this sort of shooting?

Guess it´s really just to few overlap. Strange nevertheless. But that´s definitely not a bug in the software . . . :cool:

I do agree about the overlap and about the vignetting of the lens but with the .lcp file, no more vignetting... I am a bit anoyed about NN5, they said it goes to 300mm.........

Let's stop here that topic, unless someone has really something very new to bring, I have a panogear, but I don't find it very reliable for that sort of job, and not fast enough.......

Vertical vignetting is slightly visible there too.

A trick to watch vignetting is to reduce display size and to use the horizontal scroll bar to move the pano fast...

Just out of curiosity... why shoot so many small images for a pano like that? Especially with a high quality full frame camera like a D700? Is this going to be projected on the side of a building? Could you have achieved the same results easier and faster with a wider lens and more overlap?

I realize that this may be an interesting technical exercise but as far as the resulting image goes, is there a specific reason to shoot 72 images with a 300mm?

OK, so we need more overlap to reduce vignetting. But we need less overlap to get a better stitch.

I think we need a way to specify where APP should look for CPs. see http://www.autopano.net/forum/t11003-overlap-minimizer

Resolution, size. There are people who shoot 200 images with a 300mm - i´m one of them . . :cool:
Very high sharpness/ optical resolution are unrivaled when shot using long (excellent) lenses and many images.

Sure I can understand that.

What do you use this ultra high resolution for? Large projections on buildings? Billboards?
