Calling all Digitalistas! Checked my mailbox yersterday, and what to my wondering eyes should appear but a copy of B&H's new The Digital Photography SourceBook. It's 8 3/8" wide, 10 3/4" long and 1 1/8" thick. Over 718 pages chock-full of large pictures and loads of information. It's enough to make an old film fanatic like me have serious thoughts about . . .
