File size
[编辑]It looks like the file size increased twofold after the last edit by Jacek Halicki. What was the point? Enivid (留言) 09:46, 23 December 2019 (UTC)
- @Enivid: We have a recommendation that photos sholdd be uploaded to Commons with the highest resolution and smallest compression. Quality is more important than size. --Jacek Halicki (留言) 10:13, 23 December 2019 (UTC)
- The resolution seems to be the same. Did you use the author's RAW image to produce a higher quality JPG? To me, it looks exactly the same quality as the original image. Enivid (留言) 10:38, 23 December 2019 (UTC)
- Jpg compression has nothing to do with RAW, please read about it. --Jacek Halicki (留言) 11:17, 23 December 2019 (UTC)
- I know how JPG compression works. It doesn't explain how you were able to come up with a presumably higher quality image using the presumably lower quality original JPG image. Because right now it looks like it has just been encoded in PS using 4:4:4 subsampling scheme in place of 4:2:0, which cannot improve anything. Enivid (留言) 18:03, 25 December 2019 (UTC)
