Image:Vitraux Cathedrale Metz.jpg, not featured[edit]

Short description

  •  Info created, uploaded and nominated by Benh
  •  Info I think this picture does a good job in showing some stained glasses of the Cathedral, which has the largest surface of them in France. This is a stitched-with-Hugin panoramic picture which was hard to obtain because of the numerous parallax errors between the sources photos (unfortunately, I don't own appropriate equipment for panoramic photography). While I know some people don't like it this way, I chose not to have all vertical lines so to better show how small the viewer is and believe this is a more natural result. Because of the projection used (rectilinear) areas on the borders are streched, hence the lost of sharpness.

  •  Neutral The stitch has very high quality. I've looked carefully at it for some minutes without noticing any stitching errors, so I think you have done a good job there despite the parallax problems you mention. (I am sure though that Lycaon could spot some if he passed by this with his falcon eyes) .I don't mind that verticals aren't parallel but the projection gives some quite extreme effects near the image border where objects have aspects ratios which are quite unnatural. You have chosen a difficult subject concerning dynamic range because there are very dark area as compared to the sun passing through the stained glass. This has resulted in some over-exposed areas like the cross. This is probably a place where HDR could be a relevant technique, although I think it would be painstaking work to make an HDR pano of this! Adding the pros and cons together I come to a neutral result. -- Slaunger 20:00, 4 October 2007 (UTC)[reply]
  • That's still not an oppose ;) Actually, there were a few stitching errors, but I cloned them away with Gimp (and although I told you I was sceptical about manipulating too much a picture). The new version of Enblend does a very good job in seamlessly stitch pictures which has parallax errors now. It choose the area very carefully (wonder how they achieve this). I can understand distorsion will bother some, but keep in mind this is a very wide angle view, and this is a situation where they are unavoidable. Look at this picture and this one (only on en.wiki) (they inspired me a lot for this picture), the second one has already strong distorsions at the bottom corner, and the first one, if perspective corrected would probably show similar strong distortion. On my pano, they are probably stronger though (because of bad anchor point chosen I guess). For the HDR thing, I have this pano you probably remember about :) but this was a 2 pictures pano and here we have 6. It would have been a huge overload of work to me, and probably my small laptop would have had a lot of pain in computing it :) Benh 21:07, 4 October 2007 (UTC)[reply]
OK, thank you for the explanation. I gotta try the new enblend as I've given up on some panos with objects close to the camera which are giving me a hard time due to parallax errors. I may give it another try with an updated Hugin package. -- Slaunger 21:02, 5 October 2007 (UTC)[reply]
  •  Neutral for now - The extreme distortion becomes the subject in this picture, instead of the "vitraux". Nothing wrong with that but I'm not sure I like this particular solution. The important element which should have the honour to be represented "straight" is the altar, and it is not. Let the consensus speak. Alvesgaspar 21:01, 4 October 2007 (UTC)[reply]
  • As an atheist, there isn't any religious consideration when I compose a picture ;) But had I chosen to represent the altar straight, the right part would have suffered from even stronger distorsion than here. I tried several projections before coming to the conclusion that this one was the best compromise. Keeping the vertical lines so would have generated very very strong distorsions on the ceiling, and using an equirectangular projection really isn't pleasing to my eyes and spoils the volume perception of the interior. I'm not trying to influence your judgement, but ask you to think about how a similar wide angle POV could be achieved without so much distorsions (if someone knows please help !!)
