Last month, we told you about Shoot the Day, online photo community PhotoShelter’s plan to set aside this Sunday, July 20, to “focus energy and close the gap between buyer demand and what photographers are shooting,” and so it is almost upon us. PhotoShelter has selected the lucky 20 photographers who will spend the day on all-expenses-paid shoots in five image categories, while hundreds of others join photo editors and photo buyers in a day of demonstrations and panel discussions at the Shoot! The Day event in New York City. Among the speakers is aphotoeditor.com‘s Rob Haggart, former director of photography at Men’s Journal, who will present “Editorial Bootcamp” (on how photographers can get the attention of photo editors) before leading a discussion with photo editors from the likes of Time and Travel+Leisure. Rachel Rein, senior art buyer at ad agency Hill Holliday will present “From Start to Finish: Finding the Perfect Stock Photos for a Major Campaign.” Those who can’t make it to the sponsored events can participate by spending the day taking a whole lot of photos or, for the lazier among us, watching Blowup on DVD.
