![]() If you follow the instructions (on page 186 in my manual) and try and go to the menu option to turn on CCD cleaning, you may find it's not an option available to you in the menu. You do this at your own risk, (which is negligible as long as you don't touch the low pass filter with anything - not even a brush).ġ. He reckons it's a common problem, but shouldn't give you any grief, providing you follow these instructions. I had the same problem last week got this information from my dealer - it worked for me.

There have, I think, been suggestions in the past that the blender concerned, Verdandi, leaves visible seams, but I noticed no such effects with the Seems to me that already suggested by Peter, namely, in the Stitcher tab and the Processing section, to switch the blender from Enblend to Built-in. ![]() Nor can making random changes in the hope the problem will disappear of its own accord be very attractive. That may not be a helpful suggestion for those members of Peter's target audience who do not have the 2015 But, for me, if the problem does resurface it can be dealt with by simply opening the pto file in theĢ015 version and stitching without making any changes. Job and I would be disappointed to have to revert to the 2015 version. The 2016 version of Hugin does seem to do a good So, what can be done? If the bug could be cured as it affects Hugin that would be ideal, but seems rather unlikely. However, as a non-expert, I am far from sure the bug dealt with at the start of the bug correspondence must be the one weĪre facing, because that bug was apparently already long-standing when Bruno Postle wrote in 2011, whereas ours did not surface in Hugin, as far as I know, before Is causing it, and therefore how to cure it. Which image(s) is/are affected seems unpredictable.įrom the correspondence on Launchpad pointed to by lukas, it is fairly clear there has been a long-standing bug in Enblend. The problem can be precipitated (or, apparently, sometimes avoided) by small changes to the stitching set-up. I never met the problem while I stitched with earlier versions of Hugin, but it seems a regular occurrence when stitching with the 2016.2.0 version, to which I have just The attached reduced-size version of Peter's map including the village of Holywel (see his message of at 17:41:56). For anyone who is interested but is not already familiar with this effect, it occurs in stitches like I'm now meeting the black-patch problem Peter Cooper has identified.
