I am putting together a series of articles on 3D for the special Christmas edition on www.photographers-resource.co.uk/nl the free online magazine and resource website for DSLR users. This includes at least 10 articles and 4 projects. I am aware of a number of programs to calculate the stereo base, but an not aware of any look up tables. Does anyone know of any tables that work or have experience using data from spreadsheet versions, that I could take and generate a set of tables that I could make available as a free file. Best wishes Keith
