Wherever you go, bring along a photography guide with you on your iPhone or iPod Touch - Photo Guide lets you browse valuable tips and visual examples about different aspects of photography, includes useful calculators to calculate exposure and depth of field, and provides a handy glossary of photography terms and definitions.

The Guide section of Photo Guide includes tips and visual examples of a broad range of topics useful to both beginners and more experienced photographers, including digital vs. film, choosing a camera, accessories, taking photos, composition, lighting, advanced techniques, touching up photos, printing photos, sharing photos, and travel photography.

The Exposure Calculator provides a valuable resource in the field for photographers of all skill levels that are manually adjusting their cameras for exposure. Using an intuitive interface, you can select the current lighting, ISO speed you are using, and then select either an f/stop or shutter speed. The exposure calculator will calculate and show you the corresponding shutter speed required for the lighting, ISO, and f/stop selected, as well as the corresponding f/stop for the lighting, ISO, and shutter speed selected. You can change the values and recalculate on the fly, or simply shake your iPhone or iPod Touch to reset the calculator.

The Depth of Field Calculator provides another valuable resource for field photographers of all skill levels. Using a similar scrolling interface, you can select your film/sensor size, focal length, f/stop, and distance to the object you are shooting, and the calculator will calculate the hyperfocal distance, the near and far limit of focus, and the total depth of field where objects will be in focus for those selections. You can change the values and recalculate on the fly, or simply shake your iPhone or iPod Touch to reset the calculator.

The Glossary provides a handy reference of a variety of terms and definitions relating to photography, from Ambient Light to Histogram to Zoom Lens. A scrollable index is provided to make it easy to quickly move through the glossary and select an item to view its definition.

Photo Guide stores all of its content offline, allowing you to keep the guide and calculators at your fingertips when you are out taking pictures, without requiring a connection to the Internet.
