Stock houses OnRequest Images (www.onrequestimages.com) and Photonica (www.photonica.com) announced an exclusive agreement that will provide Photonica customers with seamless access to OnRequest Images' Custom Stock service. Custom Stock, according to OnRequest, is a hybrid between purchasing stock imagery and hiring a photographer, providing high-quality custom photographs to spec in 48-72 hours, at a price comparable with conventional rights-managed stock imagery. "Photonica is well known for its commitment to helping bring the most creative ideas to life," says David Norris, CEO of OnRequest Images. "Our global network of over 1,700 photographers will be made available to 'shoot-on-demand,' adding a whole new dimension of service for Photonica customers." The OnRequest Images/Photonica partnership is expected to create a higher demand for the emerging field of "assignment stock" photography, claim the companies, providing many new opportunities for photographers around the world. Photonica will offer Custom Stock beginning next month, focusing initially on its North American customer base.
