Image rights pages

Hi! I responded to your question about 'French PD after 1923' on my Talk page. Have to say I admire what you're doing. There's a lot of criticism of CP about copyright, and it's completely appropriate that some attention is paid to this issue here. Most of those odd-named image_rights categories are (I think) Rebollo_fr's creations. He has a wealth of old advertising, and it must be said it's sometimes the only source of a picture of a camera. In some cases, I believe there are advertisements for cameras that may not even have been produced. Others are good for showing (say) what variety of lenses was offered, or what cameras were comparable in price. I think such uses are completely defensible as scholarly, but excessive use for decoration is considerably less so. Cheers! --Dustin McAmera 10:11, 24 March 2011 (PDT)

Lens

Dear God. If you are ever looking for a chewy topic to sink your teeth into, please take a look at the page lens. It needs serious rewriting, and possibly breaking up into several different pages. It's unimaginable to me that we don't have an explanation of spherical aberration anywhere in the wiki... --Vox 19:45, 8 April 2011 (PDT)

Yes, parts of it seem to have been written by an enthusiastic if underinformed teenager.
It starts off alarmingly with a photograph captioned "lens element's surfaces: 1. ground, 2. polished, 3. coated". Of course I can easily fix the apostrophe, but the larger problem is that the photograph is utterly uninformative/unpersuasive. I'm inclined to retitle it "three lens elements with a light pointing at one of them". Or, better, just to remove it.
Spherical aberration is a matter of physics, and only thanks to this a matter of photography. I cannot do better than "Spherical aberration" (Wikipedia), and though that article is flawed I'd happily send people there. Zuleika 21:54, 8 April 2011 (PDT)
