- Question Is it possible that this image could have been uploaded in some format more appropriate to a two-dimensional work, like .PNG? It's rather large as a .JPG. Daniel Case (talk) 17:36, 27 March 2017 (UTC)
- Dear Dani, I'm not expert in image format and colors palette, maybe and only maybe this image is not absolutely a plane 2D image with text and simple graphics, however, I agree with you and take a look to this article. Colin maybe has a vision more complete of what format use. Unfortunately this image does not come from a raw file, so a png will only be lighter but it will have the same quality at best. Thanks Dani --The Photographer 19:44, 27 March 2017 (UTC)
- That cartoon nicely illustrates the problem with JPG, with all those little gnats flying about the black text on white, though the problem is reduced if the quality settings are high. The Photographer how did you create this? Is it a stitched photo? If so, were your intermediate images exported as PNG or TIFF or JPG? If you'd used TIFF (or PNG) for intermediate files, then the output could have been a TIFF or PNG as well as uploading JPG. But if you've used JPG as an intermediate, then there's not much advantage to now saving as PNG as you say, since it is already in a lossy format. I suspect that for this image, the benefit of a lossless format will be lower than for a modern computer-generated illustration on pure white, and the shading of the crumpled paper will compress well in JPG. On the other hand, the black stippled texture in the illustration is quite hard for JPG to compress well, as it is more appropriate for gradual changes in tone like one gets in a photograph of a natural scene. I appreciate that using TIFF for intermediate files and output file, for stitched photos, can consume a lot of disc space and require a lot of processing. This image is very high resolution, so any drawbacks to JPG will be relatively minor. In terms of colour, both formats allow embedded colour profiles. -- Colin (talk) 07:44, 28 March 2017 (UTC)

- Support Good resolution. Perhaps I am seeing a tiny amount of colour noise and CA. Did you apply a lens profile and tick the "remove CA" box? But that's just a pixel-peeping issue, not relevant to the vote. -- Colin (talk) 07:44, 28 March 2017 (UTC)
- Thanks for your explain. It was a stitched photo from 18 images (6 images x (3 on more to apply the ISO reduction noise)). At the beginning, I thought that I was taking these pictures in raw, however, when I got home I found with the "nice" surprise that this had been taken in jpg. This is the first time that happens to me is probably part of the learning process of this new camera, I'm sorry. BTW, I added a "panorama" template to explain that it was done using 6 images how result of join 3 differents images (to remove iso noise) for each image. I applied a Noise reduction LR filter, however, I think that it work better with the RAW image. Let me know if it's ok for you. The result is a image not downsabled or downsized.

- Alternative restored candidate version
- Info At the request of Daniel Case, I created this PNG version. BTW, To take advantage of the PNG format richness I decided create a restoration from the original version. --The Photographer 12:44, 28 March 2017 (UTC)
- Support - I find this impressive. Perhaps the whites are just a tad too bright, though; I'm not sure. -- Ikan Kekek (talk) 22:46, 28 March 2017 (UTC)

- Oppose The artwork is not pen-and-ink but more like charcoal/pencil on paper. So there is quite a lot of grey in the drawings, and in the attempt to create a pure white background, some of this has been lost or made darker. -- Colin (talk) 17:31, 29 March 2017 (UTC)
- Comment When I do something wrong I usually tell to myself "I hope that Colin does not realize it", however, this is not the case. --The Photographer 19:41, 29 March 2017 (UTC)
