About DoF
What's Different About DoF?
DoF is graphical
DoF's camera-like display lets you enter parameters by pointing and dragging and then shows you the results immediately. It's unique double-cone also illustrates blur as a function of subject distance.
DoF does diffraction
Unlike most other calculators, DoF determines depth of field taking both diffraction and focus blur into account. Diffraction can be a major factor, especially for newer digital cameras with high resolution and smaller sensors.
DoF does f stops
Like most other calculators, DoF can compute depth of field from aperture and focus distance for a given lens. What is more useful however is that given a range of distances, DoF can determine the f stop and focus distance that produce the sharpest image taking diffraction into account, and what the worst case blur will be.
DoF does macro
Standard depth of field equations break down for macro photography – DoF has a Macro mode that lets you determine depth of field by measuring the field of view at the subject distance. From the field of view it then computes magnification and from magnification the depth of field.
DoF does focus stacking
DoF has a Focus Stacking mode that shows you how to increase depth of field based on combining multiple images focused at different distances.
DoF does blur
DoF can tell you exactly how much blur your images will have at each distance. The reference manual includes a set of images that illustrate what different blur levels actually look like.
Confused about circle of confusion?
To calculate depth of field, you need to know what size circle of confusion to use. The circle of confusion specifies how much blur you find acceptable – too large a value leads to soft images while too small a value makes for too narrow a depth of field. The best value depends on how you are going to view your images and various other factors. DoF's Camera dialog gives you full control over all the parameters that determine circle of confusion and the reference manual includes a thorough discussion of the issue.
Professional Documentation
DoF has a Quick Start manual built in (just tap the settings menu icon or button) to get you started right away. There is also a complete reference manual available as a PDF file that provides detailed instructions and tips on using DoF, background information on depth of field, and sample images illustrating the effects of different camera settings. The reference manual can be downloaded at: www.dl-c.com/DoF
A compatible version of DoF is also available for Windows computers at: www.dl-c.com/DoF

This is great! I used to use a little wheel thingy that expodisc made (I believe) but this is just a little bit better (the UI & the numeric display specifically). Thanks! Most devs would pack the screen with ads too, those are terribly distracting (especially for artistic pursuits). Gorgeous interface!

A very good DOF app. If your fundamentals are not clear, suggest you read the manual first.

Incredibly useful - but you have to already understand the interplay between aperture and depth of field (hey, it's geometry). If you don't already understand it, reading the help file will get you a good bit in the right direction. Hint: think of the way an acute triangle changes as you change the width of the base. Supports multiple ways of calculating "circle of confusion", profiles for different cameras, takes diffraction into account (and you can even specify the light color - diffraction's different if you're shooting IR. Free / no ads (and it's worth plenty) Thanks!

I like the interface, but it's confusing how to make adjustments. Would be best to have a lock button at the top of each column, then you could adjust things easier depending on your needs.

I haven't used a better tool to calculate depth of field, hyperfocal distance, etc. ever. It's easy, comes with a comprehensive manual which even includes formulas, it's more or less easy to use and has a desktop version. And it's free, which is something I find incredible for an app of this quality. Highly recommended, no doubt about it.

Great app! A bit tricky to understand what exactly is clickable and control settings as ranges close in on pixel sizes.

Like someone before me said, lockable dials would be better than buttons. Whole UI is a bit enigmatic.

Rules of thumb for DoF really don't work. Markings on lenses are not accurate enough. The viewfinder is too small to really see sharpness. This app does all the hard calculations for you. Also calculates diffraction loss of sharpness. Really good documentation as well. Free and no ads!

Really good. What would be the cherry on the top would be to display the Front, Back and Range distances on the main screen - at the top above the distance chart - after all - this is the depth of fields that has far more meaning than a visual. Need to do this for both the App and desktop version. Well done!

A fine DoF calculator. No adds. Single Page for 99% of the stuff. Took me too long to notice you can pinch zoom *only* on the right side of the DOF area, and move the distance on the left and middle side. Lens and blur can also be pinch scaled. I had to read most of the reference PDF to find out what blur meant (it's simply CoC = 1, 2 = blur is 2x CoC, etc) Would appreciate Speedbooster integration (so I don't have to set up different cameras for each booster) It would also be cool to see a conversion to pixel size of blur or % of captured image. Thanks for making this handy tool!

Not just a different way of checking DOF but also a useful tool for stackers showing how to distribute images in a stack.
by K####:
Fantastic app! Very functional, quick, interactive. Not very clear which sliders can be adjusted in different modes and which cannot - needs half an hour of playing around to get used to. Best thing for me is the ability to switch between the traditional "print based" definition of DoF and "image based" one that takes the number of megapixels into account. Perfect for portraiture but not easy to use for landscape (the relevant focus distance scale is too short on the screen), macro mode seems broken.
