Nature Photographer's Toolbox (NPT) is a suite of applications designed to aid and educate nature photographers. These tools include Depth of Field, Sharp Star and Hyperfocal Distance calculators.
In addition to a full range of calculators, NPT also contains Camera Safe, a way for you to document and photograph your gear in case it is stolen or to provide a list for your insurance company. All this information is kept on a secure server and can be accessed remotely from anywhere.
As an added educational bonus, the Matt Cuda Photography Podcast can easily be accessed from within the app from an easy to use built in audio player.
