Review: DOFMaster lets you take control of you camera's depth of field
One of the most distinctive characteristics of any photograph is its depth of field: Is the entire frame in sharp focus, from near-to-far, or only the subject? For a serious photographer, achieving the right depth of field isn’t an accident or trial and error; it’s deliberate and planned.
There was a time when photographers would carry a depth of field guide around with them—a small booklet filled with spinning dials and radiating grids of numbers that looked sort of like an engineering diagram for the space shuttle. These days, you can get the same information more easily using an iPhone app. And that puts precisely planned photos with just the right depth of field within your reach.
DOFMaster is the iPhone extension of the excellent DOFMaster.com, a website that offers ways to help you calculate depth of field from every conceivable format, including your browser, iPhone, Android phone, and a Windows app.
Calculations: DOFMaster makes it easy to calculate your depth of field.
DOFMaster is the very picture of simplicity; the entire iPhone app occupies a single screen and features just five buttons. To get started, specify your camera. A drop-down menu lets you choose from among general categories like 35mm, APS, a number of medium- and large-format cameras, or compact digital. You can also select your specific digital SLR model.
