I would be interested to have a reply from KOLOR, at least a confirmation of the bug, if possible an indication of a sensible workflow to process these images...

KOLOR ???

I have stopped using the deghosting arrow of APG 3 : it does not work with bracketed images and exposure fusion. You really have to do the work by yourself. I have never done it with trees and leaves, but the idea is the same: you have to leep them in one single exposure to avoid ghosting effect and...

I practice exposure fusion with APG. My most issue was to remove ghosts while processing spherical panoramas with APG. In my own case, the ghosts were pedestrians or cars. My technic is to use the 0 pictures as the reference and make sure that they stitch together without ghosts (due to moving pedis...

Thanks to both of you for all these suggestions. I have tested as suggested by Klaus : exposure instead of gamma - No improvement. I will try with no color correction... but does that make sense with 3 exposures and exposure fusion ? I have not tonemapped the images: I have shot 3 brackets and put a...

Thank you, Lumelix. I will give a try to your different suggestions. However, I suspect that vignetting is not the cause of the problem. Would APG not correct the vignetting, not a single panorama would be acceptable. The software has for long had an issue with the sky; I thought that it had been re...

To Lumelix: I confirm that the rendering has not improved with your suggested solution; regarding vignetting, I have not tested it. What method would you suggest to process it ? I am not sure that Nikon Capture NX2 can perform an automatic vignetting correction. It will only apply the value that I w...

Thank you for this advice, Klaus. I have done as you propose and will get the result tonight, when I am back home. What I however noticed is that the preview has remained unchanged (grey areas still there) following these modifications. I did not change the position of the reference anchorS (1 per b...

That old and recurring autopano bug

Over the week end I have stitched (APG 3. Beta - Windows 32) a panorama with a lot of sky: - about 10 images horizontally aligned (X 3 for bracketing) shot with telelens - color correction set to LDR - multiband level set to 0 The town below the sky is perfect but the sky at, say, 5 different places...

Wrong Metadata - Help

After having fiddled with Photoshop to optimize the images that I will use to create a panorama, I have noticed that they now have a wrong shutter speed: the normal exposure image has taken (during the fiddling) the overexposed image speed. These images are fisheye. I have tried, after having loaded...

Je soutiens ce commentaire et considère qu'il faut aller encore plus loin. Je suis en train d'exploiter des panoramas fait à  New York en Avril, avec bracketing (0, -2 et +2). Sans Ptgui et la possibilité d'exporter les masques antifantomes pour traitement des photos sous Gimp ou photoshop, j'aurais...

To Niall The only deterministic way I have found to deal with ghosts is to use the demo version of PTGUI. With it you can accurately control the ghosts that you want to delete and the holes that you need to make in order to keep the moving features you want in the image. PTGUI (in its demo version) ...

Merci pour la réponse. Je ne suis pas sûr d'avoir compris le "donc" du raisonnement logique dans le 1er paragraphe, mais j'ai bien noté que l'anti-fantôme ne fonctionne pas en exposure fusion. Après m'être tapé à  la main tous les nettoyages de piétons (avec l'aide des masques de PTGUI que j'exporte...

Même chose, le preview peut être bon et le résultat final complètement différent. J'ai le sentiment que lorsqu'il y a beaoucoup de mon...

APG 3 - I like it

I just loaded APG 3 and tested it on my latest assembled pano. I like it: - the possibility to have little planets and other projections ! - the red and green targets ! I was about to report on two bugs; in fact, this was me not having paid enough attention to the new MMI (eg the new way to select t...

Cool. I will try it obviously, especially the new antighost feature (constrained-based masking).

Question (after reading your conclusion) : For APG 2 licensed user, will APG 3 be for free ?

Il y a tant de causes possibles que les gens ont peut-être peur de donner une réponse. 1/ L'exemple visualisé correspond à  quel objectif ? Le fisheye ? Si c'est le cas je note une focale de 18.55.

Yes - This is the right answer. In order to be more accurate, you will have to use your preferred image processing software to edit the images with the ghosts you want to delete, create alpha channels, delete the ghosts to remove, and save the images as .png files. It may happen that the person you ...

To DrSlony: I agree with you that there is much more information in a raw file than in a jpeg (recently, I saved a panorama from a mess thanks to the raw files) and that there is a lot of options to create a tif file from a raw. There are however circumstances where bracketing is necessary. Consider...

Bracketing is the answer. You can try, while developing your raw file to develop it with several different exposures and see if the resulting underexposed image is OK. Otherwise, as you have the possibility to shoot again: use bracketing. Autopano can handle exposure fusion; otherwise, you can use a...

To Hans: And your conclusion is ......... ?

I continue to be happy with 8.7

But I have not tried anymore to take the risk of an other focal length. I may have been unlucky once; I will never know !

Alexandre, This is however not my (very limited sofar) experience. I am a new Samyang user, but my first experience with it was a mess. This is why I made a test with PTGui to get confirmation (and I got it) that my pectures could result in a correct panorama. PTGUI calculated a focal length of 8.7 ...
