: you optimise only if you change control points. Since you are moving an image manually into place and not touching any control points, optimising is useless, you will just end up having to level it again.
"Guess unlinked image location" works great when you position an image at the start and end of a row, hard link them to the ones with the row below, and the images in between are garbled up. Then APP usually spaces the garbled up images evenly between the two hard linked ones.
01 02 03 04 05 06 07 08 09
These are unlinked and garbled up: 11,12,13,14,15,16,17,18
10 is hard linked with 01, 19 is hard linked with 09.
If you use smartblend for rendering, you will notice that some panos have a pinched zenith, a very visible cone. You will have to render those panos twice: once using smartblend for the whole pano, and another time using multiband for just the sky, so it doesn't pinch the zenith. I used to fix pinched zeniths using clone/heal, but the end result was never satisfying, there are just too many gradients coming in from different directions sometimes, especially if you use a polariser (sometimes a bad idea for a pano, sometimes great), so I recently started to always just re-render using multiband to get the best quality zenith. I hope smartblend2 wont pinch the zenith.klausesser
: if you shot the zenith, letting APP blend it in will give you a better, smoother result than cloning/healing it, and faster.
Has anyone figured out when APP pinches the zenith when using smartblend? It doesn't always happen to me, just sometimes.
