Simply put, depth-of-field is how much of a photograph is in sharp focus from front to back. Digital Landscape Photography: In the Footsteps of Ansel Adams and the Masters, Michael Frye, 2010.

We can achieve critical focus for only one plane in front of the camera, and all objects in this plane will be sharp. In addition, there will be an area just in front of and behind this plane that will appear reasonably sharp (according to the standards of sharpness required for the particular photograph and the degree of enlargement of the negative). This total region of adequate focus represents the depth of field.The Camera (Ansel Adams Photography, Book 1), Ansel Adams, Tenth Edition, 1995

This app works very well as a long exposure calculator for novices in long exposure photography as well as professionals. The design of the app is great and everything is straight to the point. I am grateful for the lack of annoying advertisements. This is all I at least what I would expect in a paid app but for free. An alarm at the end of the timer would be nice, but I seldom use it. I use this app every time I take a daytime long exposure photo using a neutral density filter. It is far more efficient than a reference card or many other apps that I have seen. Overall, it is very simple, effective, efficient, and easy to use for photographers of any skill level. Although, I wish that it included aperture. Also, is the base shutter speed with or without the ND filter?

Just downloaded and tried this photography app. I found this to be an easy exposure calculator when using neutral density filters. Enter the basic settings and the app will automatically tell you the time of the exposure. If the exposure is more than bulb (30 secs) the app will open a timer. I rate for 5 stars. However, its hard to find anything perfect because there is no such thing. But a new update could include an alarm for the timer. I thank and recognize the author for making this app and free for photographers and users. I'll look and follow him. This app is exactly what I was looking for and should help me using ND filters. Thank you again. 🙂

Another important control for landscape photography is depth of field, the amount of sharpness in a scene, from close to the camera into the distance away from the camera. It's sharpness in depth. Landscape Photography: From Snapshots to Great Shots, Rob Sheppard, 2012.

Depth of Field (DOF) is the range of distance in a photo that appears to be in sharp focus ... Depth of field is a creative decision and one of your most important choices when composing nature photographs. Nature Photography Photo Workshop, Nat Coalson, 2011

If you set the camera's focus to the hyperfocal distance, your depth of field will extend from half of the hyperfocal distance to infinity—a much deeper depth of field. Complete Digital Photography, Ben Long, 2012.

... the hyperfocal distance setting ... is simply a fancy term that means the distance setting at any aperture that produces the greatest depth of field. How to Use Your Camera, New York Institute of Photography, 2000.
