Long story -- I used other people's images to create the montages, and I dutifully got permission to use the images, but I didn't get explicit confirmation that the owners actually owned the images. The light-meter has cleared, and the Nikonos II will probably clear. The light meter is rare, and in this case well photographed, so that was the more important of the two.--John Bessa (talk)15:07, 30 July 2010 (UTC)[reply]
Does anyone know of an online resource which describes focus and aperture settings recommended with the Nikonos (I through V) extension tubes? Would a sentence and citation about this improve the utility of this article? Also, relative to the framer, which part of the subject will be in sharpest focus...its proximal (defined) end, its distal (defined) end, or into the subject, at a depth about equal to the framer's width? Does aperture profoundly affect this? I can imagine it may be hard to answer these questions within theguidelines.Newportm (talk)04:09, 17 July 2009 (UTC)[reply]
Actually I think that it would violate the "how-to" rule; this is an encyclopedia and not a how-to site. This isn't a show-stopper however because you can create a similar page on the|Wikiversity and direct people there. Wikiversity is conceived of as a school version of the WP.--John Bessa (talk)15:50, 30 July 2010 (UTC)[reply]
Underwater Lenses: Difference between amphibious and UW
It would be really interesting to understand and relate why UW is better than amphibious underwater. Increased diffraction of light plays a role and that the lenses are "anigstigmat" in relation to this, but I have no other knowledge. One of the sources says "saturation," and early underwater photos lacked exactly that, so I wonder if the glass content and coating are working her in some complex way.[1]--John Bessa (talk)15:44, 30 July 2010 (UTC)[reply]
There were Ektacolor Type S and Type L, the C-22 predecessors to Vericolor Type S and Type L. There is no article page for either Ektacolor or Vericolor, but there should be (at least) one. If one meant Ektacolor-S instead of Ektacolor-X, change the link as appropriate. Ektacolora and Vericolor are negative films similar to Kodacolor.Gah4 (talk)23:31, 12 November 2018 (UTC)[reply]
