Types of shirt neckline

{{resolved}}


Article(s)
Neckline
Request
The article for neckline is illustrated with a confusing assortment of photographs (close-ups, full-length portraits, group shots) that don't clearly depict different styles of neckline. Could someone please make a series of drawings for the styles listed in Neckline#List of neckline types? Here are non-free examples from dressmaking books: [1][2][3][4][5][6]. -- gnu57 19:39, 2 February 2021 (UTC)[reply]

Hi @Genericusername57:. Probably not the best, however here is an attempt to make the requested graphic. Tsange (Talk) 09:46, 9 February 2021 (UTC)[reply]

Thank you, that's fantastic. It's just what I was looking for. I really do appreciate your taking the time to make this. Cheers, gnu57 19:10, 9 February 2021 (UTC)[reply]
Hi @Tsange:, Could order the necklines alphabetically please? Auguel (talk) 23:07, 9 February 2021 (UTC)[reply]
@Auguel: Thanks for spotting that. I have reordered the list. Tsange (Talk) 07:50, 10 February 2021 (UTC)[reply]

Pictograms

Article(s)
w:pl:Ręce Boga and later translate to Hands of God or something
Request
I'm asking just for few pictograms from a vase. Articles about this on all Wikis are bad and English one was even removed, but I have finally good sources and I'm working on this. You can see these pictograms here (image) or here (film from a museum). The pictograms in the image are listed and I need pictograms a (man on horseback), c (woman on horseback), and e (deer). Having b would be nice too, but it is not necessary (it is unfinished or broken) and d exists as File:ReceBogaSwargi.svg. All I need are simple .svg with simple geometry, just like file mentioned before. -- Sławobóg (talk) 19:17, 15 January 2021 (UTC)[reply]

Abney effect

Article(s)
Abney effect
Request
The image should be changed so that each step of blending is done in linear RGB light; see Talk:Abney effect#Diagram. I am awful with image-generation tools like Pillow, so I am going to shamelessly let a more capable coder-illustrator take this. -- Artoria2e5 🌉 06:40, 19 February 2021 (UTC)[reply]

Extended content

Artoria2e5 This is a difficult one to visualize. I have been looking around and there are not many images/animations to show this. I saw a couple I think are showing it [9], [10]. I really don't think using an animation adds a lot of value and it seems as RGB 0, 0, 255 is good to show this.
I have made a svg draft which I show here as a png. Please ping me, thanks. --Goran tek-en (talk) 19:14, 24 February 2021 (UTC)[reply]

@Artoria2e5: This should probably be done using the HSL color model. This allows the use of arbitrary hues and the hue is maintained by design. See this example I generated [11]. If this makes sense to you I can create a visualization which looks like the one in the article. Or we can make some changes if they make sense (maybe removing the animation). Auguel (talk) 02:46, 25 February 2021 (UTC)[reply]

  • Auguel No, just no. Using HSL is just a different way of doing the blending wrong. The fact you can see Abney effect in the middle of the blue one is again because a 00 to ff gradient happens to be "impossible" to get wrong. The fact that you can see it at all shows that it does not maintain hue, by the way.--Artoria2e5 🌉 03:15, 25 February 2021 (UTC)[reply]
@Artoria2e5: How do you propose measuring hue objectively? Of course using HSL and varying the lightness value maintains hue, what do you think the H stands for? Here's an example with all the colors [12]. Auguel (talk) 03:28, 25 February 2021 (UTC)[reply]
Although I'm reading the article and it seems that the Abnery effect if more of an issue of saturation rather than lightness. This can also be visualized with HSL [13]. Auguel (talk) 03:53, 25 February 2021 (UTC)[reply]
Ok was still thinking about it (lol), |}and I think actually mixing white light should cause both an increase in lightness, and a decrease in saturation. I went back to how the original author did their mixing and I mixed white light but in HLS color space. This means I averaged the lightness with max and averaged saturation with min but kept hue constant. Please look at this [14] (I guarantee you that hue is constant). Auguel (talk) 04:25, 25 February 2021 (UTC)[reply]
  • Auguel, the HSL "hue" differs from the hue that humans perceive. Take a long deep look at the blue gradient, and tell me again it doesn't look purpley in the middle. Any fiddling with HSL generated by sRGB ends up mathemetically equivalent to weighted averaging directly in sRGB. A bunch of experiments have been done to figure out how people see, and this is what you are holding onto? --Artoria2e5 🌉 07:17, 25 February 2021 (UTC)[reply]
Artoria2e5, Auguel As I said to begin with "This is a difficult one to visualize". When reading your discussion above and in the other place I think like this. There is color theory and then there is our issue to present a specific "function" of color theory. To me it's two completely different things. You can talk about HSL, HSV, RGB or other color system but in the end we view them on a monitor working with RGB. My monitor is different from every other monitor (and it changes all the time, aging etc.). So what you see I don't see.
I did my blue draft as RGB and now I have made a new draft where you can see the measured values in that draft here. As you can see hue is the same on them if that is something you didn't believe.
To me the different color systems in e.g. Inkscape is just there so we can work with the system we prefer. In the end when viewing it on a monitor it is always RGB, the rest is theory.
So we want to show the Abney effect how do we achieve that? Color is always perceived differently depending on surrounding (that is why I have a grey background to minimize this) and is very individual and other surrounding of the monitor and the monitor itself. So we can never get this perfect. If you want anything from me so please ping me, thanks. --Goran tek-en (talk) 11:14, 25 February 2021 (UTC)[reply]
Goran tek-en See but you are using HSL to measure the hue which according to Artoria2e5 is not valid.
Artoria2e5 I understand human perception differs from computer measures, isn't that precisely what we are trying to illustrate? Yes I see the purpley color, but isn't the perceived change of hue the entire point of the Abney effect? So again I ask, if not HSL then how do you propose we objectively measure hue? Auguel (talk) 13:02, 25 February 2021 (UTC)[reply]
Artoria2e5, Auguel HSL or HSV gives the same hue reading, no difference.
How do you know which system the software is using. It shows you HSL HSV RGB CMYK Hex color code or what ever but what does it USE. I don't think it has all the system at the same time so maybe it uses Hex color code all the time and when you ask the software to show you RGB it converts. This is what I think the software does so even if it shows you HSV it still uses the same system all the time.
So by this I mean the discussion|} of which system we see and believe the software is using is of no value. If you still want anything from me, just ping me. --Goran tek-en (talk) 13:26, 25 February 2021 (UTC)[reply]
Goran tek-en I understand, and agree, but Artoria2e5 does not approve of any of these systems. I am waiting for them to propose a new one. Auguel (talk) 13:33, 25 February 2021 (UTC)[reply]

  Request taken by Goran tek-en (talk) 18:14, 26 February 2021 (UTC). Okay, I went back and figured that we really can only have three examples from RGB as it's supposed to be monochromatic. Even then such a demonstration would only wekaly work in a LCD display with LED backlight or an OLED display because CRT is very not monochromatic in its emission, while LED at least only have one peak. (The fancy laser Rec. 2020 display would be actually perfect.) The blue example is expected to be most visible, the red second, and the green almost not at all, from the curved chromaticity diagrams I have seen. Goran tek-en, do your thing. --Artoria2e5 🌉 01:35, 26 February 2021 (UTC)[reply]

Artoria2e5 You will never have any sort of control on how someone will view this. So remember that what I will do is an illustration of the Abney effect, it is not the effect itself. --Goran tek-en (talk) 18:12, 26 February 2021 (UTC)[reply]
Artoria2e5 Draft-2. --Goran tek-en (talk) 18:37, 26 February 2021 (UTC)[reply]
Goran tek-en The colors are good. I mean, I can clearly see the effect for blue on my LCD screen in the 50-80% opacity range, which is as good as it can go. As for making it an illustration... I am not sure I get you. Do we intentionally vary the colors so people can feel it? (The text is a bit off because of the gamma issue. You can try color-interpolation: linearRGB for an actual opacity percentage in the light-mixing sense, but you are likely to see the scale being very washed out. Well, we aren't claiming it's in 10% steps, so it's not wrong. FWIW, the actual percentages are [0, 1.0022825574869039, 3.3104766570885054, 7.323895587840543, 13.286832155381797, 21.404114048223256, 31.854677812509184, 44.798841244188324, 60.38273388553378, 78.74122893956172, 100].) --Artoria2e5 🌉 03:53, 28 February 2021 (UTC)[reply]
Artoria2e5 This is the illustration. What I mean is that we can not perform the Abney effect in a real sense. What we do is show an illustration of the Abney effect. There is a big difference in that and that is why it doesn't have to be (it can't) as in theory, we visualize it so one can understand it.
  • Goran tek-en Just pick the 10% steps. You misunderstood the thing about the "actual percentages": I was saying the 10% opacities you pick in the code actually correspond to the weird values I gave in physical light blending, because gamma. Look up color-interpolation: linearRGB if you are curious. --Artoria2e5 🌉 08:39, 2 March 2021 (UTC)[reply]

Artoria2e5 I will not upload this as a new version of the previous image, I want to upload it as a New image, so I will need the following;

  • Name of the file
  • Description (/language)
  • Captions/s (/language)
  • Category/ies at commons

to be able to upload it at commons. If you don'y know about Captions read here.--Goran tek-en (talk) 11:38, 2 March 2021 (UTC)[reply]

Goran tek-en It is indeed impossible to overwrite the original image, especially since I've decided only the RGB primaries can show the effect nicely. Anyway, I recommend:
  • File:Abney_effect_RGB.svg
  • {{en|An illustration of the {{w|Abney effect}}. The RGB primaries on a typical display is not monochromatic, making the effect weaker than the usual experimental setup. However, it is usually still possible to see the effect in the blue example. The mixing ratio step appears to be 10% in the {{w|gamma-corrected}} {{w|sRGB}} mixing system, but is in fact <code>[0, 1.0022825574869039, 3.3104766570885054, 7.323895587840543, 13.286832155381797, 21.404114048223256, 31.854677812509184, 44.798841244188324, 60.38273388553378, 78.74122893956172, 100]</code> in linear light. (A true 10% step would be appear too washed out.)}}
