one of the best pictures I have ever seen. Sehr schön! (Orientalist in der de:WP)

Help, please…[edit]

Hello Slaunger. Please, could you fix the metadata problem (EXIF) of the photo File:Webysther 20150509172554 - Estação da Luz.jpg? Thanks! 😄 ArionEstar 😜 (talk) 00:21, 6 June 2015 (UTC)

ArionEstar: Sure, ✓ Done. -- Slaunger (talk) 07:28, 6 June 2015 (UTC)

mountain hut photo[edit]

Cabane des Diablerets02 2014-09-20.jpg

Dear Slaunger, thank you for starring one panorama of mine. I deliberately did not fully align vertically, as in my opinion the building becomes visually top heavy. Easily done, as you can see on the right, and that image also shows what extra image material is available. Feel free to suggest a crop of yours, or whether I should point the virtual camera in a different direction or change projection. -- KlausFoehl (talk) 14:49, 10 June 2015 (UTC)

Hi KlausFoehl, thanks for your message. I understand what you mean with top-heavy. When you have a very wide field of view (unfortunately I can not see from the EXIF what the focal length is, or how large the field of view is), a strict vertical alignment leads to a top-heavy look as you say. I think my main problem is that the entire building appears to the leaning to the right, and I think that maybe a small CCW rotation and a partial perspective correction would be an overall improvement with a reasonable tradeoff between alignment, and keeping realistic proportions.
You have very good light and colours there. I like the red and white in the Swiss flag along with the red-white shutters and the dark clouds in the background. Last summer I tried to do something along those lines as well. As a Dane, I like red and white. Smile -- Slaunger (talk) 15:13, 10 June 2015 (UTC)
Cabane des Diablerets03 2014-09-20.jpg
Hi Slaunger, en:Hugin (software) puts FOV info into the User comments section, but this info is wrong if you crop the image, even within hugin. Please see the uncropped image for which the FOV 123 x 118 info is correct. When I first stitched the photo, I wanted to vertically align the chimney but then decided to put the vertical near the ladder. In any case, as output from hugin it is already corrected in perspective (barrel and such), I just had elected to incline the plane for the chosen rectangular projection. And I was well below the building, even with my arm high up in the air as you can see from the shadow.
I was just staying in that hut for the night, most afternoon the sun was gone, and when the sun happened to come out, I just dashed out to get the view, leaving some supper to get cold. -- KlausFoehl (talk) 08:07, 11 June 2015 (UTC)
Hi KlausFoehl: OK, thanks for explaining these details. I am familiar with Hugin, although nowadays I use PTGui Pro, which is very similar, but has some additional features and is a more stable (commercial) product. -- Slaunger (talk) 04:41, 13 June 2015 (UTC)
Thanks for the answer. BTW (thread hijacking), that recurring voting patter 86-87-88 is unusual indeed. Most puzzling for me is number 86 which shows a nice scene but the horizon is heavily non-horizontal. -- KlausFoehl (talk) 12:11, 15 June 2015 (UTC)

How I can?[edit]

Hello. How i can to edi Template:Valued image. i want to the valued image criteria link on Persian(Farsi) language to Commons:معیارهای نگاره‌های ارزشمند Qian Nivan  Talk 19:37, 15 June 2015 (UTC)

Hi Qian.neewan: Thank you for wanting to help with translations in Farsi. I am sorry, but I have never acquired a detailed understanding of how localization works in the templates. But if you look at the last section in {{Valued image}} (at least in the English version), there are some instructions for how to make a new language version of that template. I propose to follow those instructions. -- Slaunger (talk) 14:17, 16 June 2015 (UTC)
thankyou for your answer Qian Nivan  Talk 14:29, 17 June 2015 (UTC)

Featured picture critique[edit]

Hi, I mean no disrespect and hope I don't come off as such, and I readily agree with all other critique presented against it, but for the Nymphaea odorata image could you tell me exactly how the petals are overexposed? I've asked some people I know and no one is saying it is overexposed. I dont see any blowout on the petals and can still see texture in them. The luminance histogram also does not indicate overexposure. The petals can be naturally a very stark white. I would like to improve so my failing to see overexposure bothers me. Thank you in advance. SanctuaryX (talk) 04:15, 24 June 2015 (UTC)

Hi SanctuaryX, You are very welcome to ask such questions, and I do not see it as disrespectful at all, on the contrary. The overexposure if a little top-right of the center of the flower. It is in the green channel. I do think there is a loss of texture in that area and also in the centre yellow region of the flower. I have pinged you with an email. If you reply I can send you a screen shot from Lightroom indicating excatly where the overexposure is and how you can also see it in the histogram. With that said I am quite impressed by the picture quality of the smartphone you have used. It is, I think something of the best quality I have seen from such a device. It is very challenging though to reach FP quality with a smart phone (I am not aware it has ever happened, but I could be wrong). Normally, you need at least a decent compact camera or a DSLR to get the kind of baseline technical quality, which is expected at FPC. Photographing white flowers and e.g. snow is challenging, and I doubt that you have enough control options on your smart phone to adequately control the exposure. It is best to shoot such subjects with areas of strong relative luminance in raw format and then develop it to a jpeg with adequate lowering of highlights using adequate software such as LightRoom. I do not know if that is even pssible with your device. -- Slaunger (talk) 11:16, 24 June 2015 (UTC)

Bot in VI[edit]

Bot in VI has not worked for several days. I reported the problem to Daniel, but maybe you know how to start the Bot. Thank you for your opinion. Have a good day. --Archaeodontosaurus (talk) 05:26, 24 June 2015 (UTC)

Hi Archaeodontosaurus. I am sorry I do not have access to the bot as such and I have no detailed insights into what may be the problem. I have written a personal email to Daniel asking him to look into it in case he has overlooked the message on his talk page. -- Slaunger (talk) 11:49, 24 June 2015 (UTC)
Everything works again. You're still a rare efficiency! If you have five minutes you can look at the problem of the greek debt? Smile --Archaeodontosaurus (talk) 16:07, 24 June 2015 (UTC)
Yeah, Archaeodontosaurus. Dschwen noticed my mail, glad it is up and running again. -- Slaunger (talk) 17:44, 24 June 2015 (UTC)

Freedom of Panorama[edit]

Hello Slaunger, In the coming days there will be much media attention for the subject Freedom of Panorama, as it is under discussion in the European Parliament. Freedom of Panorama is one of the keystones Wikipedia is built on: being able to take a picture of a public place and use it freely, like on Wikipedia. Denmark has Freedom of Panorama (for buildings), so we can use pictures of buildings on Wikipedia, but the Danish Wikipedia has no article about it and people can't read in their own language what it is about. So my question is if someone can translate Freedom of Panorama to Danish, the whole article or only the first section. Thank you! Romaine (talk) 10:42, 29 June 2015 (UTC)

Hi Romaine. Thanks for all the efforts you are putting into this deeply concerning proposal regarding the limitation of FoP in the EU countries. I am afraid that I am not a good translator nor do I have the time to translate it. Maybe Villy Fink Isaksen has the time and is willing to do it? -- Slaunger (talk) 19:38, 30 June 2015 (UTC)
There is a short article, da:Panoramafrihed in danish translated by Palnatoke, this translated from Sweidsh, may be Kaare, Palnatoke or MGA73 can do the translation I am not good at that. --Villy Fink Isaksen (talk) 19:54, 30 June 2015 (UTC)

EXIF bug[edit]

What's this EXIF but that you are working around? Your File:Facade, Kollhoff Tower, Potsdamer Platz, Berlin, Germany, 2015-07-13-3381.jpg is now missing the colour profile that was in the previous version. -- Colin (talk) 11:40, 29 June 2015 (UTC)

Colin I am using the exiftool script devised by Bawolff on Commons:Village_pump/Archive/2015/04#Error_in_metadata_viewer?. I guess some arguments for exiftool eliminates the colour profile. Exiftool has plethora of options, and I have just used it as some kind of magic. Maybe Bawolff knows how the script can be improved such that it retains the rather important colour profile? I do see the problem. In the original export from lightroom the color profile data are there, but after running it through exiftools with the script it is gone. Not good :-(. -- Slaunger (talk) 19:34, 30 June 2015 (UTC)
I've left a message for Bawolff. Can you look at my uploads to see if any of my images are affected. I use Jeffrey' Friedl's Creative Commons and Metadata Wrangler as part of my export routine for Wikipedia (I use his Flickr plugin too). When I use my "Wikipedia" preset export, it helps ensure I have CC properties set up to record CC BY-SA 4.0 in the EXIF, etc. The Metadata Wrangler is also useful to remove private info from the EXIF file, but retain what is necessary. The Flickr plug-in is not easy to set up, but I have it configured to create folders like on Flickr and to recognise the "Family" tag as meaning the image is restricted to family only, rather than for public view. -- Colin (talk) 19:57, 30 June 2015 (UTC)
Colin: I've checked the most recent version of your 10 most recent uploads. Your EXIF data are very pro, and I do not see the kind of corrupt data, that I have been seeing after exporting from Lightroom (I do not use any plugins). The only slightly peculiar thing I noticed were some gibberish characters in the 'user comments' field in File:Gherkin from the Sky Garden 2015.jpg. -- Slaunger (talk) 20:06, 30 June 2015 (UTC)
That field is generated by Hugin. Must be a bug in the recent version. EXIFtool shows the same bad characters. Well, if you want to consider those plug-ins then that would seem to avoid the EXIF PHP corruption problem. -- Colin (talk) 20:21, 30 June 2015 (UTC)
Hmm the User comment field is odd there. 
 and 
 are how you escape a windows newline in HTML, and then replacing # with \# is how you would escape a # sign in something like a shell script. Does indeed look like a bug in the tool you're using to write exif. Bawolff (talk) 06:21, 1 July 2015 (UTC)
Thanks Colin for trying to help. I cannot get Bawollfs updated script to work, it still looses the colour profile. I think I will now bite the bullet and have a look at the plugins you are referring to (except the flickr one as I do not really use flickr). -- Slaunger (talk) 19:26, 1 July 2015 (UTC)
After installing and enabling Jeffry Friedl's Metadata Wrangler and Creative Commons plugins it works! -- Slaunger (talk) 20:43, 1 July 2015 (UTC)
For a simple projection like that, have you tried the built-in panorama feature of Lightroom to see how it compares? -- Colin (talk) 07:46, 2 July 2015 (UTC)

Reverted to FP version[edit]

Thanx Slaunger for noting it. Agree, FP shouldnt be changed but if some dont like it can make derivate work. I put all my FPs on watchlist to take care for this in future. Thanx again. --Mile (talk) 20:19, 30 June 2015 (UTC)

No problem, Mile Smile. -- Slaunger (talk) 19:26, 1 July 2015 (UTC)

No color-space metadata and no embedded color profile[edit]

Hi, Regarding the 2 images for which you mentioned this issue, is it fixable for the TIFF files? Thanks, Yann (talk) 22:23, 5 July 2015 (UTC)

Never mind. Thanks to Revent, I fixed that. Yann (talk) 11:01, 6 July 2015 (UTC)
OK, Yann, I was too slow there. Glad that Revent could help. -- Slaunger (talk) 14:32, 6 July 2015 (UTC)

Yet another colour profile question[edit]

Hi Slaunger, thank you for your comment on Commons:Featured picture candidates/File:Pont de Chancia02 2015-05-10.jpg. After some googling I understand that a color profile could be added with exiftool. Would adding a standard gamma=2.2 metric be acceptable? My main issue is that the stackoverflow help for exiftool recommends to obtain an icc file from another image. Defies the purpose. There is a Canon Powershot G12 icc file out there, but I suspect it is not meant for JPG file but for the CR2 raw files. What are your thoughts? -- KlausFoehl (talk) 10:58, 6 July 2015 (UTC)

KlausFoehl, the cropped image lacks the sRGB colourspace tag in the EXIF but your original wide one has this tag. So what software did you use to crop it? It should be possible to redo the crop in a way that doesn't lose the EXIF data. You shouldn't have to worry about specifying the gamma if you specify sRGB (because that standard => 2.2 gamma).
@Colin: The crop, cut-and-paste with gimp, was a brief reply to than one person deeming 180-deg images out of place. I might even withdraw that alternative at some point. -- KlausFoehl (talk) 13:50, 6 July 2015 (UTC)
For your original image, if your images are out-of-camera JPGs rather than created by a professional tool like Lightroom or Photoshop, then they often do lack a colour profile. I think manufacturers do this to save 4kb per JPG. One would hope that the sRGB colourspace tag was sufficient for web browsers to display the colours properly. Sadly it is not (I mean to write an essay on this) and without a profile, such images can look bad for people using wide gamut displays. Currently, though, that's a small percentage of the internet users and I hope the situation with browsers gets fixed in the future.
I think missing a colourspace tag is a valid reason too oppose at FP (our guidelines require it), but we don't go as far as to insist on an embedded profile. Too many people's images, and images uploaded from Flickr, lack this. So I'd regard it as a "nice to have" and I wish more people took care to include it.
If you are keen to find and embed an icc sRGB profile, there are several places to find them (I assume you did create the JPGs as sRGB rather than AdobeRGB!!!!) Have a look at ArgyllCMS. I contains tools for extracting and inserting icc profiles from/to images. But also it comes with their own freely-licensed versions of the sRGB profile (and others) which are highly regarded and could be used instead of trying to find an image to extract one from. -- Colin (talk) 11:59, 6 July 2015 (UTC)
@Colin: Thank you for the link, but I have not yet explored it. From previous searching today, I came across sRGB_IEC61966-2-1_black_scaled.icc md5:4b699a4c3a7d97acf0a356aed883fd85 which by the name sounds reasonable to me. I also came across an icc file with my camera name in it, but is it for JPG or CR2 files? I assume that the camera does some internal magic (i.e. enhancing colours) when creating JPG from the sensor data, hence there should be a JPG-specific color profile, better tuned to the camera than a generic profile. For the panoramic I have used the camera JPGs as input, but most times I also shoot RAW so there are also CR2 files for the same images. I wonder whether one can obtain a visibly better end result starting from them. -- KlausFoehl (talk) 14:24, 6 July 2015 (UTC)
KlausFoehl, I think there are some unusual sRGB icc files around and different versions numbers too. See this link which I don't pretend to fully understand. My suspicion is that the Canon Powershot G12 icc you found is used by programs like RawTherapie to profile the camera raw file. Every camera raw file is different. Perhaps some raw conversion programs use icc profiles to calibrate that aspect. But what one wants in a JPG is a standard colour profile rather than one peculiar to your camera. And sRGB is the most compatible choice. If your camera output JPGs in sRGB format then it will be using the standard sRGB profile (or Canon's implementation of it) and so that is what you want. If you have some CR2 files and your raw conversion software has generated JPGs from them, do they contain sRGB colour profiles? If so, then you could extract the sRGB icc from those. Otherwise I think the Argyll CMS one I linked would be a safe bet. One can use icc profiles for all sorts of colour calibration: cameras, monitors, scanners and printers. But when we publish to the internet, the only reliable profile choice is sRGB. -- Colin (talk) 15:53, 6 July 2015 (UTC)

KlausFoehl In my limited understanding the colour space are just a recipe for how to convert the numbers in the file into colors. The camera specific profiles, where a certain amount of vividity in colors, sharpness, noise reduction, etc is applied happens in the camera in the conversion of the luminoscity data in the raw files to the data values in the jpg. Thus, I think these two aspects are separable issues. -- Slaunger (talk) 14:59, 6 July 2015 (UTC)
