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.

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.

Calculators

Depth of Field Calculators

NPT contains both simple and advanced tools for calculating depth of field. In simple mode, the photographer supplies the sensor type, focal length, distance to the subject and aperture.

Advanced mode adds print size and viewing distance to provide a more accurate calculation.

Hyperfocal Distance Calulator

When shooting landscapes, for example, nature photographers often need the ability to determine where to focus in the scene to get maximum hyperfocal distance.
For example, you may want a rock in focus only 4 feet from your lens and the depth of field to extend to infinity. This tool will help you do just that.

Sharp Star Calculator

Astronomy photography has really come of age within the last several years due to advances in camera and lens technology. Because it is often difficult to determine how long of an exposure you will need without causing star blur, NPT has a tool to calculate what shutter speed and focal length you will need to get you the correct exposure. Use it to get as close to that 30 second mark as you can without sacrificing ISO.
