Probably unbeknownst to most of you, Alberto Tirado is a PhotoForum volunteer who prepares member's articles into PDF format and then these files are installed in an archive accessible to everyone. The latest contribution to this set of articles is one that was written by Kostas Papakotas on the subject of Converting a Screw mount lens to a Bayonet one. The link to the page listing all the available articles available in PDF format (as well as contribution instruccions) is located at: http://www.rit.edu/~andpph/pf/pdf-files.html This may also be an appropriate time to mention that the list's webpage also provides links to a large variety of items such as its FAQ files, a large and eclectic list of links, a Database of Schools offering Photo Instruction, Travel Tips to many locations, specialized articles, Bulletin Boards (such as for Situations Wanted/Available) and many other features. The main PhotoForum website is located at: http://www.rit.edu/~andpph/photoforum.html or at http://www.rit.edu/photoforum Andrew Davidhazy for PhotoForum on the Internet
