Hi Klaus
294 images ? Have you make bracketings ?
In other case, it's clear that APG can't really deal with this hard exposure differences.
Image 1 shows the reality ?
APG is magic but can't conjure

Hey Martin!

I know, the exposuring is extreme. But it´s not un-realistic. I didn´t do bracketing - i used a 105mm@f8, 20% overlap. That´s why it took 294 shots. I used JPG - that might be another problem - in small . . which is the reason for about 50000px instead of moren than 100000px
width (an 85mm provides 84000px using a fullframe camera).

Actually i´m exploring whether the 5D2 has some issues with this kind of exposuring - i mean i didn´t have that using my old 20D.
Maybe something in the internal processing of JPGs runs s bit wild . . i deactivated any kind of picturestyle in the camera of course.

Shooting RAW i also had this kind of uneven sky images, but not THIS heavy - the opera-scene: www.360impressions.de/Oper
(84000px width shot as RAW, 200pics, 20% overlap)

Georg kindly offered to try the JPGs - i´ll put them on my server in the afternoon.

I posted it here because o know there are lots of 5D2 users who also use APG.

best, Klaus
P.S.: the exposure was ONE stop over. Usually that´s not such a big problem at ISO 100 or 200 that it´s impssible to render.

But really: maybe the camera has an issue here - i´d like to pin the issue down in each direction.

Hi Klaus
You show us in image one or three the real world with no color correction.
When you shoot manually with fixed exposure time, then the light have cange several times, most in the shadows.
When light haven changed so much, perhaps the is an issue with the shutter ?

Hi Martin!

The light was constant, the shutter works perfectly - i had it checked on thursday by a camera-mechanic, who also cleaned the sensor.
That was before i shot this pictures.

I always use anything set to manual on the camera. No Automatics at all. I measured a point of average light - usually, with RAW, i would have
stopped down after that to have the highlights safe and would light up the shadows a bit (!) in the RAW converter.

It´s the original JPG_small size - i didn´t want to change it to exclude issues by scaling.

funny. each project seems to be a voyage of discovery
but we will conquer also this continent

I played first with your project loading the .pano file by changinging the color anchor points for indifidual images. This helps for top right sky images to equalize the differences. no satisfying results yet.

than I started to load the images to a new project. because no exif available the defaults of 50mm were used on my apg
I detected it without color correction and used gigapixel preset because more than 100 images used.
the result was a top side down and left-right mirrored pano (with no anormal results, all colors looked like in my second try). after using the rotation tool rotate left twice I got following result in screenshot the top result. so a wrong focal length used creates such result?
again: this triangle pattern was not there before using the rotation tool (2x for 180" rotation)
than I did the same again by using 105mm and f8 manually setting for the images. result is in sceenshot after 2x rotation left the bottom pano...
... here I will try the next steps (in some hours)

positivley surpised me that I did not used any xml file for importing the images and only some view images were misplaced. '(still unresolved in my screenshot)

Georg

EDIT1: if I use the left rotation tool I get result from screenshot. BUT If I use the right rotation tool twice instead I do get a correct result!!! reproducable on my side!

Hi Georg
Check the cooling solution of your GTX260
With zero load, the temperature should be around 40 degrees. Maybe some dust in the cooler.

Guess then you might have some bugs who live in the cooler . .

Hi Georg
You're welcome ! Set a date for next cleaning
