Just finished reading a somewhat forgotten Leica book entitled "Leica 35mm Color Magic" by Walther Benser. Great color photo tips, 1956 style. Charming in that "Bygone era" sort of way. He stresses that projecting chromes not enclosed in glass will ruin them. Is this true with today's E-6? Can any of you experts advise what to do. I have been told that encasing chromes in glass is a total waste of time and money. Experts??
