Scanner...

https://commons.wikimedia.org/w/index.php?title=File:Mr._Bouatier_working_on_meter,_1954.jpg&curid=30755448&diff=164488000&oldid=149609367: Why on earth would we classify a file by what brand of scanner was used to scan the photo? Who could possibly ever want such information? - Jmabel ! talk 10:44, 28 June 2015 (UTC)

I'm not entirely sure. I suppose some scanners are better than others and you may want to compare them? Basically since the data exists in Exif, and some scanner categories had already been created, I figured I may as well continue to classify them. Once the categories / mapping table are set up the bot can do it without additional effort. --ghouston (talk) 11:14, 28 June 2015 (UTC)

If it's not an error, it's at least a badly named category. The photo wasn't "taken with" an Epson Perfection V700. It was taken in 1954 with one or another film camera, and merely happens to be scanned with an Epson. - Jmabel ! talk 17:59, 28 June 2015 (UTC)

Yeah, the naming needs consideration. Several methods have been used for different models of scanner. I think part of the distinction is between digitizing an existing document/photo vs photographing a real-world object: there's not actually a lot of difference between scanning a photo and taking a photo of a photo with another camera. Thus there are also files around that are "taken" with two different cameras. Besides that there are "photographs" of 3D objects made with scanners: Category:Photos taken with scanners. --ghouston (talk) 03:49, 29 June 2015 (UTC)

Maybe I'll just rename all the scanner device categories to "Scanned with". --ghouston (talk) 05:53, 3 July 2015 (UTC)

Kodak EasyShare C182 category

I just discovered the category Taken with Kodak EasyShare C182, and decided to add it to more than several of my pictures. Should I have waited for the bot to tag my pics instead? ----DanTD (talk) 18:02, 3 July 2015 (UTC)

You can add the category yourself if you like. The bot may have done it eventually, or it may have found files elsewhere instead (it doesn't generally add to categories that already have more than 100 files.) --ghouston (talk) 22:31, 3 July 2015 (UTC)

That's kind of why I asked. I wanted to give it a chance to tag others, and as of this writing there's still a chance for it to do more? ----DanTD (talk) 00:23, 4 July 2015 (UTC)

The bot could easily find 100 files in many cases if I pointed it at a user who has uploaded a lot of files with that camera type. But I'm avoiding that for the moment since it may not give much variety of images (they may all be aircraft or buildings in one town in Germany or something). I'm running it now on random files, but it's slow at the moment because I'm still creating missing categories as it finds them, which are still quite numerous. The mapping table from Exif to category names is not perfect yet either. So it still has quite a good chance of finding files in this category, although I don't know how long it will take. --ghouston (talk) 01:12, 4 July 2015 (UTC)

Taken categories

Is there any way to tell the bot to stop adding to a specific camera category? Since it is a bot, it sometimes selects undesirable images just to fill up a category. Or should I just remove some of the less desirable images and let it keep trying to fill up the category? Royalbroil 05:14, 7 August 2015 (UTC)

The bot is picking images at random, so some of them can be undesirable images such as low resolution. However technically those images are still in scope for the category, so I don't see any particular reason to remove them. Once there are a decent number of images in the category, hopefully at least some of them will be useful. One way to stop the bot would be by adding images to the category manually, since it won't add to categories that contain 100 or more files. I could also stop it from processing any particular category, but is there any reason to treat one category differently to any other? --ghouston (talk) 07:39, 7 August 2015 (UTC)

Okay, that's fine. Thanks for the reply. Royalbroil 18:04, 8 August 2015 (UTC)

Categoryzation of my pics

Hi ghouston, lately the bot now and then tags some of my pics for the Category:Taken with unidentified Canon PowerShot S100. As for my pics, they could/should be tagged more precisely: While my former pics (ending with "SLxxxxxx.JPG") were taken with a Samsung L700 and get categorized correctly, all my latter pics (ending with "IMG_xxxx.JPG") were taken with a Canon PowerShot S100 and thus belong into the Category:Taken with Canon PowerShot S100. Would it make sense to go through all of my pics to categorize them at once? Regards --C.Löser (talk) 07:31, 12 September 2015 (UTC)

I think probably it would. I assume you have only uploaded your own photos, and not from sources like Flickr that may contain photos made by Digital IXUS? --ghouston (talk) 11:50, 12 September 2015 (UTC)

Yes, the few exceptions either have no metadata at all or were not taken with a Cannon. --C.Löser (talk) 16:38, 13 September 2015 (UTC)

OK, I've done all your S100 photos. --ghouston (talk) 07:40, 14 September 2015 (UTC)

Max 100?

Why is there a set limit to max 100 images per cat? Seems a bit ambigous in my opinion, since then we can't do any real statistic of which camera is used more than others etc. Is there a reason for this? Josve05a (talk) 11:19, 7 March 2016 (UTC)

• I offered to limit it to 100 in the original bot request, since there was a query about whether these categories are a good idea and whether it could be done better with a forthcoming Wikidata on Commons system (which is currently on hold I think). Processing all images would also be a massive job and the bot would probably need to run constantly, or at least for many hours a day, to make much progress. --ghouston (talk) 05:02, 8 March 2016 (UTC)

Categorising edited images

I have just reverted an edit that you made on File:Crawley banner Tilgate Shopping Parade.jpg, because this is an edited image, and so I don't think that it is helpful to put it in a camera category. As this is not the first time that I have done this I thought that I would bring it up here. All the images that I have reverted have been in a Wikivoyage banners of... category, and have the word banner in the title. These images are all cropped to have a 7:1 aspect ratio, and in some cases other editing has been done. I assume that the category will be used by users looking to compare cameras, but please say if you see other uses where edited images are wanted. AlasdairW (talk) 22:53, 22 April 2016 (UTC)

I'd say it would be too hard to determine automatically whether a particular image is edited or not, so this bot ignores such issues. Cropping is a relatively minor change, other images could have been adjusted by photoshop, or processed from raw files in different ways. I'm just assuming that if an image was taken with a particular camera, then it belongs in the category regardless of processing, and it's up to any users of the category to deal with that. --ghouston (talk) 00:25, 23 April 2016 (UTC)

Desire 816

Hello.Most of the pictures I shoot for Commons are Category:Taken with HTC Desire 816 Please review the photos that I uploaded and add the category.Thank you ديفيد عادل وهبة خليل 2 (talk) 15:07, 13 July 2017 (UTC)

I ran it on your uploads, although it wasn't really needed since there were already over 100 files in Category:Taken with HTC Desire 816 and other categories --ghouston (talk) 01:37, 14 July 2017 (UTC)

Syntax-ignorant

I don’t think that a bot ignoring this pretty straightforward comment syntax can be deemed a valuable asset for a wiki. Incnis Mrsi (talk) 10:34, 25 February 2018 (UTC)

Comments and <nowiki> ... I'll fix it. --ghouston (talk) 20:55, 25 February 2018 (UTC)
