I believe it is more about spreading the control points than finding them. The more the control points between 2 photos are widely spread, the better the results of the adjustments made by Hugin. Hmm, I feel this last sentence is not pretty, I hope my meaning is clear.
Also, if for some reason it is difficult to find precise control points (for example the branches in the trees have moved), then having more control points can help because averaging more errors will possibly yield a more correct result. 2016-10-05 20:26 GMT+02:00 Krystal <[email protected]>: > 50 percent..., thanks for that tip, I think my 2-photo effort was not more > than 25 percent overlap, if that.
