I understand why you were tempted to do it - but engravings and paper are naturally "warm" in colours, and greyscale makes it look unnaturally "cold". This image is up for Featured Picture, and really does need to have natural colours for that.
Basically, while converting to greyscale works really well for black and white pictures, it's not really appropriate for engravings, lithographs, and the like, which are printed on paper - those who know such media will find they look rather odd in greyscale. Adam Cuerden (talk) 05:11, 11 July 2010 (UTC)
- OK, I understand, that certainly sounds logical -- to best emulate the "feel" of the real life medium. I was just on a spree of palette reductions, and certainly don't mind if anyone reverts. LobStoR (talk) 09:46, 11 July 2010 (UTC)
- I skimmed them, and the vast majority are clear improvements. It's just really the non-photographic stuff to watch for. Adam Cuerden (talk) 16:49, 11 July 2010 (UTC)
File:Monticello church damages 1974 Super Outbreak.jpg
editHi,
Why did you degrade this image File:Monticello church damages 1974 Super Outbreak.jpg from 24 to 8 bits ? This make it looks grainy. Pierre cb (talk) 17:54, 12 July 2010 (UTC)
- The original file was already grainy, I don't think that it is any worse after my greyscale conversion. However, if you think it looked better before, then go ahead and revert it -- I certainly won't take it personally. Cheers! LobStoR (talk) 17:58, 12 July 2010 (UTC)
- I must say that it is true after inspection. Just curious to know why the conversion, apart from slightly reducing the byte size ? Pierre cb (talk) 18:10, 12 July 2010 (UTC)
- For consistency, so that any particular black and white photo has some degree of consistency with any other black and white photo. Also, like you said, there is that slightly reduced filesize :-) LobStoR (talk) 18:17, 12 July 2010 (UTC)

Where is the documentation on "AdvComp," I don't want any loss of data on this image... — raeky (talk | edits) 00:33, 14 July 2010 (UTC)
- My optimizations were still lossless, the displayed bitmap is still 100% pixel-for-pixel identical to the original. AdvanceCOMP is open source, and uses the 7-Zip implementation of the DEFLATE algorithm to achieve superior compression. LobStoR (talk) 15:13, 14 July 2010 (UTC)
As far as I can tell, the version you just uploaded over mine is exactly the same resolution. Am I missing something? - Jmabel ! talk 01:59, 14 July 2010 (UTC)
- You're correct -- I got confused on that one. Sorry for any confusion I may have passed on :-) LobStoR (talk) 15:06, 14 July 2010 (UTC)
Thanks. Geagea (talk) 02:08, 17 July 2010 (UTC)
Thanks for the change on these files. I tried to remove transparency but unsure if I did it correctly, is this one correct File:A Treatise on Geology, figure 67.png ? Phe (talk) 10:03, 21 July 2010 (UTC)
progressive JPEG
edit@File:360-degree_Panorama_of_the_Southern_Sky_edit.jpg: Progressive jpg is always a problem. It should be avoided since it does not work (at least with large images). See Commons:File_types#Images. Cheers --Saibo (Δ) 18:17, 24 August 2010 (UTC)
Psira
editCertainly, you had a reason to zoom in and cut the image File:Psira island.jpg. However, I prefer the old version and maybe others also do. So, if you want to apply significant changes to the appearance of an image, e.g. the dimension of the picture, I would appreciate if you'd use a new file name. Btw: The cropping was not lossless, as the coast line can't be seen anymore, which could serve as a kind of scale in order to guess the dimension of the island. Please, restore the old version. Thank you. --84.176.131.91 23:11, 25 August 2010 (UTC)
- I am fine with reverting it to the full version. If you are looking for someone to "blame" -- my edit was simply repairing the "damage" done by User:Greece11's messy crop. I personally believe that derivative works (such as a crop) should be uploaded under a new filename. LobStoR (talk) 18:03, 27 August 2010 (UTC)
Lossless crop
editHow can i do a cropped picture lossless? --Greece11 (talk) 15:25, 3 October 2010 (UTC)
- I use jpegcrop to crop, but there is other software, too. Thanks for all your great image uploads, I hope you don't mind my edits! LobStoR (talk) 18:40, 4 October 2010 (UTC)
How can io do it ni this site? Please answer im my talk page. Your contributions are very helpful. --Greece11 (talk) 15:28, 8 October 2010 (UTC)
- Specifically:
- jpegcrop.zip, which contains:
- I hope this is more specific. Cheers, LobStoR (talk) 22:56, 11 October 2010 (UTC)
Simple substitution
editAcctually Bots/Work requests is the perfect place for simple subsitutions. One alternative might be to do it with AutoWikiBrowser by yourself. Greetings --Schlurcher (talk) 08:57, 12 December 2010 (UTC)
