- Support I think it is “eye-catching to the point where users will want to read its accompanying article.” Therefore, it satisfies the requirements to win FP status, IMO. Another reason I like it is raeky often nominates ‘scientificy’ pictures, which casts Wikipedia in a fine light. Greg L (talk) 05:03, 30 July 2010 (UTC)
- Comment: Almost certainly a support from me, but a couple of comments. Firstly, this would belong in planetary science as opposed to the category you chose, but, secondly, the moon has a slightly unreal quality about it, as if it has been cut out from a magazine and stuck on black paper. It's most noticable on the bottom left "corner". Anyone know what's caused this? J Milburn (talk) 11:42, 30 July 2010 (UTC)
- I know what you mean (I think), but my first impression is that it appears like a cut out because it isn't a smooth curved edge and there is no atmosphere to soften the edge as you might expect. I'm looking at it from a work computer and another thing that I noticed is that the black doesn't seem black enough. As it's a work computer (with a crap monitor), I don't have any tools available to confirm if it is indeed close to true black or not. Ðiliff «» (Talk) 12:03, 30 July 2010 (UTC)
- It's been cutout by nasa, the unprocessed image was what was in the infobox on the moon's page before I added this one, File:Mimas before limb sharp.jpg, as you can see it was shot with a strange background which is the edge of Saturn. NASA obviously thought a solid background would look better as opposed to this weird gradient effect. Also NASA wouldn't of excluded anything important scientifically during this edit, I'm sure. — raekyT 14:50, 30 July 2010 (UTC)
- In that case they have done a pretty bad job of it, the source image has no distortion around that limb but the processed version does. Do you know where I can download the original uncompressed version of File:Mimas before limb sharp.jpg? I am sure I can do a better job! - Zephyris Talk 15:33, 30 July 2010 (UTC)
- Probably at the source link for the file, but that is just the RED light spectrum, I'm sure the final processed version is multiple images composited from several spectrums, it's also flipped around since in the unprocessed south is up, but in the final processed one north is up. — raekyT 15:48, 30 July 2010 (UTC)

- Comment I have recreated this image from the source file here. This involved centering Mimas, masking out the limb of Saturn and increasing the contrast. This version does not have the distortion around the lower left limb the nominated image has. This version is lower resolution than the picture nominated above and has some noticeable jpg blockyness, either I have not found the absolute original source or the nominated version above has been upsampled. - Zephyris Talk 16:41, 30 July 2010 (UTC)
- I'm sure they're both vastly downsampled. I'll look later this evening for a higher source, a lot of times people upload the JPEG version when a TIFF exists which is higher, hard to say if thats what happened here. Also it's possible NASA's version is from multiple wavelengths of light not just the RED spectrum that picture was of, as evidenced by the much more dynamic contrast on theirs. — raekyT 17:06, 30 July 2010 (UTC)
- Support Always good to get close-up photos of celestial bodies, too bad they couldn't get color. --I'ḏ♥One 17:27, 30 July 2010 (UTC)
- BTW this isn't a photograph, it's a photo mosaic, that might be the reason for the issues you guys are discussing. --I'ḏ♥One 17:34, 30 July 2010 (UTC)
