Nature Photographer's Toolkit 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 GearSafe, 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.
