f/8 DoF Calculator
f/8 DoF Calculator is an elegant solution for the photographer who needs to find depth-of-field while on location. It lets you input details about your digital or film camera and will tell you exactly what you have in focus at a given f/stop. Easy to operate, it even links you to the Wikipedia article on depth-of-field just in case you need a refresher course.
Comment
Several developers have produced DoF calculators for iPhone, but this is certainly one of the best -- judged to be one of five favorite iPhone photo apps by CNET. The user interface is clear and largely self-explanatory with successive screens for entering parameters and reading the results.
First you input your camera model and lens type, or you can enter maximum/minimum focal length of the lens on another screen while setting maximum aperture and minimum focus distance. The readout gives you all the information you need: even the percentages of in-focus depth, behind and in front of the subject. It's a lot cooler than using a DoF calculator made from two cardboard disks, even though the outcome is much the same.
