I thought I'd throw out a shout-out to the best publication ever in my last 5 decades of photography. Two of which were as a professional studio. I've learned so much from this top-quality printed subscription in my mailbox and online. Sal Cincotta's Shutter reads like a textbook on the current trends of the business and techniques. Killer tutorials on currently-used software. Sal's contributors are nothing less than stellar. Loaded with proven practical business-sense and technical know-how is the pinnacle of achievement. Cincotta's Shutter Magazine is the eminent killer source for those in or wanting to stay in business. Worth every penny. I have every issue and refer back to them constantly. Behind the Shutter can't be beat!
