 * Weak support -- nice picture, but there is quite a lot of noise in the darker areas. I think this problem was made worse in the uploader's second version of the picture, in which he/she attempted to brighten the picture. Might be worth using a noise reduction program or something. Also, I'd have preferred a tighter crop. NotFromUtrecht (talk) 08:07, 6 April 2010 (UTC)
 * Thanks, I'll prepare an edit tonight.  Mae din \talk 08:17, 6 April 2010 (UTC)
 * Now that I'm not at work I've had a better look at the image and I'm not sure I agree regarding noise. To me, it looks like the texture of the mineral alone.  I compared it to the darker original and couldn't see much difference.  If it is noise, in any case, I think it's slight, and I'm reluctant to use a filter on this that might lose some of the detail.  But I'll ask Alchemist-hp about a crop.

 * @NotFromUtrecht: "there is quite a lot of noise in the darker areas" --> no, please look at the camera exif data! Show me a much better camera and I buy me it! The "surface" from the crystals are noisy. "I'd have preferred a tighter crop" --> artistically not valued and ineffective view. Please test a tighter crop for you self and you see it.

 * I'll concede that I can't be 100% sure that there actually is noise, since I know nothing about the physical properties of cassiterite. I certainly agree with Maedin that it's not worth trying to remove genuine noise if the result is that detail is lost. I tried cropping the picture in different ways, and my conclusion was that the amount of white space at the top and bottom of the picture was excessive. I'd prefer a version where the white space at the top and bottom was roughly equal to that at the side. I am happy to support this uncropped image, if there is no consensus that a closer crop would be better. NotFromUtrecht (talk) 19:46, 6 April 2010 (UTC)

 * Support I definitely don't see any noise, and at ISO 200 there shouldn't be. Meets all criteria.  Jujutacular  T · C 19:18, 6 April 2010 (UTC)
