Something like fog on stitched pano

[Can-C. Dörtbudak]

Hi Guys,

i've taken pictures for an cubic panorama. They fit very well but in
the output file i get on some areas something like fog on the picture.
Does anyne no this problem using enblend?

Could you post an example to show what you mean by "fog"? From your
report it's impossible to pinpoint the problem...

Sorry, you are right. There's a picture called example_fog.jpg on
ehich you can see the problem.

Cheers, Can

Can,
It looks like the sort of result you get when you have a picture
totally out of place, then it ends up being "smeared" over the others.

Given the subject I'd guess that you are starting from bracketed
exposures? I usually do that in the sequence: Normal-exposure, Under-
exposure Over-exposure. If so I would start by checking the lower
levels of the stacks particularly the zenith and nadir shots.

An easy way to check for this is to use the Fast Preview window and
first of all deselect all the "Normal" exposure shots, then deselect
the "Under" exposures and then the Over-exposures. You will probably
find one shot in there somewhere for which the positional parameters
have gone way off there will be a shot of the floor or the ceiling
that is across the middle of the wall. Typically this will have
happened if it has somehow got no control points allocated ... perhaps
it was very over or under exposed and the control point generator
could find no matches.

So either leave it out all together or if it has SOME useful detail
reset it's position and add some control points by hand.

Let us know if that helps or not.

all the best

Did you use a fixed exposure or did you use some kind of automatic exposure?
Can you also post your .pto file so we can have a look at the amount of
overlap your single images have? Do you shoot JPGs? It somehow looks (to
me) as if enblend has to combine parts of several images that contain
extreme contrasts.

Maybe masking in the right areas could help.

BTW, where in Bavaria is that church?

You are right, it is Übersee. How did you know? Have you ever been
there?

I've taken these picture with differnet exposures. I can upload the
jpgs as well. I've taken 18 RAW Pictures and developed them in
lightroom to use tthem in hugin. The pto File is called uebersee.pto.
I'veuploaded it.
