Unit sales of digital cameras will rise to 20.5 mln in 2005 from an estimated 18.2 mln in 2004, industry trade group Photo Marketing Association said. The increase of 13% pales beside the rapid gains of more than 30% in each of the last three years. The overall camera market, including film-based models, is expected to be flat in 2005, after growing by 3% in 2004. Total film sales are expected to fall 18% in 2005 to 532 mln rolls, after sliding 19% last year. Sales of single-use cameras (which are also called “disposable” and are counted as rolls of film) are expected to slip to 217 mln in 2005 from 218 mln. Some 40% of the 7.7 bln digital images printed in the United States this year will be made at retail stores, up from 31% in 2004. By contrast, 18.2 mln traditional film prints will be made in 2005, down 18% from last year. Printing of digital pictures at home will shrink to 52% in 2005 from 61% in 2004. Online photo developers are seen staying at about 8%.
