Photography Magazines illustrate the power of niche marketing.
Guerrillas have long appreciated the advantages of specialization. Recent trends in photography magazines reinforce the importance of niche marketing.

As popular, "broadness" magazines become slimmer and slimmer, and subscription costs drop to artificially low values, titles that target market niches within photography are growing in number, size, circulation, and costs.

The best example are the several publications, like B&W, targeting those who love black and white photography. Paradoxically, the more color digital photography grows, the more readers there are for black and white, only, publications.

B&W, for example, is just three years old, but is increasing in size, production value, and costs. They serve a dedicated, intense market. The fact that their back issues are becoming harder and harder to get shows the loyalty a specialty niche can develop among their readers.
The costs of issues of B&W or Lenswork approaches that of paperback books, and yet their circulation keeps growing.

Question. How can YOU differentiate yourself by specializing in a niche, instead of trying to be all things to all people?
