Consensual review[edit]

File:Avispa_(Psenulus_pallipes),_Hartelholz,_Múnich,_Alemania,_2020-08-08,_DD_72-89_FS.jpg[edit]

  • Nomination Wasp (Psenulus pallipes), Hartelholz, Munich, Germany --Poco a poco 08:50, 29 November 2021 (UTC)
  • Decline
  •  Oppose Too noisy and unsharp. Many parts are out of focus. --Hillopo2018 09:06, 29 November 2021 (UTC)
  • ✓ Done I reduced the noise a bit, if you mean by out of focus the areas in the back, isn't that acceptable for this kind of shot? to get the whole wasp sharp I'd need something like 300 images focus stacked --Poco a poco 09:24, 29 November 2021 (UTC)
  •  Support Good quality. -- Ikan Kekek 06:35, 30 November 2021 (UTC)
  •  Oppose A dead animal, as shown by the antennae. Thus, not a faithful depiction of the wasp imo. Image quality in on the borderline considering it is a focus stack. -- Alvesgaspar 10:22, 30 November 2021 (UTC)
  •  Comment What kind of reason is that to oppose? skies have to be blue, animals alive, cars red and guys ware a moustache? I cannot keep up writting down all new rules you introduce. Please, explain me how do you want to manage this kind of shot with 15 frames and this magnification if the animal is hoping around --Poco a poco 19:39, 1 December 2021 (UTC)
  •  Comment What I realize is that our approach to QIC is very different, a difference that is reflected upon our assessments. I tend to nominate my best pictures (not the excellent, those are to FPC) aiming to get the recognition of the community and taking into consideration how they can be useful to the end-users. I make no allowances to the difficulty of the shots, the unfortunate conditions or the hard work involved. Those are my problems, not theirs. Neither am I pursuing any kind of record of QIs, a goal that is obviously detrimental to quality. Concerning the present image, the end-user won’t care if it was taken with expensive gear and using sophisticated techniques. In fact, it is possible to shoot much better photos of insects, both alive and dead, as eloquently demonstrated by our (former) colleague Richard Bartz. -- Alvesgaspar (talk) 22:00, 1 December 2021 (UTC)
Total: 1 support (excluding the nominator), 2 oppose → Declined   --Augustgeyler 18:56, 2 December 2021 (UTC)

File:Vista_de_Alcázar_del_Sal,_Portugal,_2021-09-12,_DD_69-78_PAN.jpg[edit]

  • Nomination View of Alcácer do Sal, Portugal --Poco a poco 15:10, 20 November 2021 (UTC)
  • Promotion
  •  Oppose Deceiving view caused by wrong choice of projection, river is straight at this spot -- Alvesgaspar 06:53, 22 November 2021 (UTC)
  •  Comment As already discussed in CR. No QI rule prohibits this kind of projection. Fine if you want to agree on new regulations, but please, don't make them up. --Poco a poco 20:20, 23 November 2021 (UTC)
  •  Info Yes there is, in the Editing section of Image guidelies: "manipulations which cause the main subject to be misrepresented are never acceptable" -- Alvesgaspar 22:23, 23 November 2021 (UTC)
  •  Comment Poco, I'll support if you describe this as a cylindrical projection. Could you please always do that when you use one? Because it is an issue that otherwise, people who don't know this landscape would be likely to get the wrong idea. -- Ikan Kekek 06:51, 24 November 2021 (UTC)
  •  Question But why should the identification of the process, which is absolutely irrelevant for the end-user, justify the misrepresentation of the subject? -- Alvesgaspar 09:36, 24 November 2021 (UTC)
  •  Comment It tells the viewer that the scene has been manipulated in a specific way. If you hate all cylindrical projections, fine, but to me, the point is to for the photographer to be open about what they did. -- Ikan Kekek 10:16, 24 November 2021 (UTC)
  •  Comment Ikan Kekek, I don't hate cylindrical projections and they not always cause this type of distortion, it depends on the shape of the subject and the POV. What I mean (I have said this before) is that it doesn't matter what projection is used, provided the subject is not misrepresented (purposefully or not), thus deceiving the end-user about its real shape. Telling the end-user that some projection was used won't clarify him about the real shape of the subject. Of course, I'm referring here to documentary images, not artistic ones. Is my concern so difficult to understand? -- Alvesgaspar 10:33, 24 November 2021 (UTC)
  • No, and I didn't suggest that it was difficult to understand. But that doesn't mean I have to agree with it. I judge these things case-by-case. -- Ikan Kekek 19:20, 24 November 2021 (UTC)
  •  Comment I updated the file description (and added a category) to specify that it's a cyclindrical projection, Poco a poco 11:33, 24 November 2021 (UTC)
  •  Support Thanks. -- Ikan Kekek 19:20, 24 November 2021 (UTC)
  •  Support --Milseburg 15:23, 28 November 2021 (UTC)
  •  Question Hi Milseburg, could you please elaborate why you consider the projection appropriate for the subject (maybe I am making a stupid mistake)? The way I see the problem is that you have two parallel lines in front of you: the river and the horizon. The only way we have to depict both as straight and parallel on a panorama is to use the rectilinear projection. Am I wrong? Unless you consider that it is ok to show one of them as a curve; or both of them, for that matter, as in here. -- Alvesgaspar 13:24, 29 November 2021 (UTC)
The rectilinear projection has the advantage that all straight lines are actually mapped straight. However, it is only suitable for a relatively small angle of view. With a large angle of view, it results in very disturbing, unnatural-looking distortions in the edge areas of the image. It is therefore not suitable for long motifs. In the case of cylindrical projection, horizontal lines are shown curved - except for the horizon line. In landscape shots, however, this peculiarity is not as evident. Differentiate that from architectural panoramas. --Milseburg 14:15, 29 November 2021 (UTC)
  • It is evident here, as well as in the previous panorama of the same subject: the river is straight and perpendicular to the line of sight, but is appears curved in the photo. -- Alvesgaspar 16:51, 29 November 2021 (UTC)
Diego should add the coordinates here. The satellite image shows that the river is not really straight. He should also add the Pano template, which says that "the content of the image may vary slightly from reality when multiple images have been combined". So it is a good and legitimate way to show such an overview over a landscape. Every other projection has other weaknesses that do not lead to a better result as long as we do not have a viewer who can compensate for the inevitable distortions. But as I said: They are to minor for a rejection. --Milseburg (talk) 19:36, 29 November 2021 (UTC)
  •  Neutral OK, I'd really like to support this image. But at the end of the day Alvesgaspar's argumentation is convincing. If a used production method leads to very unrealistic reproduction of lines, dimension, curves etc, this can not be QI. The rules don't say anything about, this may always happen as long as it is stated in the description. --Augustgeyler 12:33, 30 November 2021 (UTC)
