One way to be sure is to compare the edges of the negative images with the edges of known ( read authentic ) Ansel Adams negatives. Negative carriers ( film holders ) over time get little nicks and dents and these show up in the negative like a finger print. If they find and exact match, then the negative were made in AA's film holders and that lends credence to him as the photographer.

There's certainly no mention of it on the major Adams web sites, or in articles Google News finds me. Unfortunately, both claims and denials may have more to do with jockeying over money than with trying to determine if the pictures are really by Adams. If the pictures are in fact by Adams, and haven't been published before, it seems like they're still in copyright, and the copyright would be owned by his heirs (or somewhere the copyrights were formally transferred to; copyrights cannot be transferred "informally"), which would seem to interfere with publication by others. However, if the family is actually denying these are Adams' work, then presumably they can't claim copyright ownership.... -- David Dyer-Bennet, dd-b@xxxxxxxx; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info
