Description
TrueDoF-Pro is a major step forward in working with depth of field. Specifically designed for working professionals, the app offers features, versatility, customisability and no-fuss ease of use to make it the ideal tool — a tool that simply does its job (superbly) without getting in the way.
And it’s a tool that works the way YOU want it to work:
* Directly set any relevant quantity you like, even the near and far limits of DoF.
* Lock any input in place; vary any other input.
Want to “work backwards,” whereby you specify the depth of field you’re after, and have the app tell you what aperture and focus distance you need? Couldn't be easier. Enter what you want directly; get instant results.
Want to lock in a particular far limit of depth of field (e.g. as a cinematographer, would you like to lock in the far end of a set)? Slide the far limit pointer to your desired distance, and hit its lock button. Freely change any other input you like.
A key (and unique) TrueDoF feature is the option to include the effects of diffraction in the calculation of DoF, giving a much more accurate indication of how sharp the image will be (see the article "Image Sharpness vs Aperture" at www.georgedouvos.com).
A partial list of features:
* Elegant, interactive, easy to read interface, with both graphical and numerical display of data
* Fast, no-fuss input; real-time output
* Unprecedented input options: Want to specify a far limit of DoF? Or a near limit? Now you can.
* Lock any input (aperture lock not available on iPhone 5s)
* Option to “work backwards” — set your desired depth of field, see what focus distance and aperture you need
* Hyperfocal function — lock your far limit at infinity
* Option to include the effects of diffraction
* Optional visual indication of the limits imposed by diffraction
* Customisability of numerical readouts (show, hide, display distances or blur size, display front and rear DoF as distances or %)
* User-definable focal length presets for the scroll wheel's rapid selection buttons, for super-fast selection of YOUR lenses
* Support for all formats up to 8x10in
* User-selectable distance scales
* Distance units changed directly on main screen by tapping m/ft button
* Optional "distance snap" function
* Optional input of focus distance via keypad
* User-selectable aperture scales (reading to f/22 or f/64)
* Aperture slider snap to half or third stops (user selectable)
* Easily switch between settings for different cameras: a simple slider to set a blur spot diameter (circle of confusion); no tedious listing of camera models
* Blur spot diameter is displayed on the main screen, so you won't find yourself working with the wrong setting
* Facility to specify wavelength, for use when shooting in the infrared or ultraviolet parts of the spectrum
* Visual indication of wavelength on the main screen
* Context specific help
* Comprehensive User Guide
A note on intended use:
In any DoF calculator, you specify a sharpness criterion — the blur spot diameter. All calculations reference that value. In some situations (e.g. landscape photography) it is best to work quite differently: Specify the distances to the nearest and furthest objects that you wish to appear sharp and, from that, determine the focus distance and aperture that will give the SHARPEST POSSIBLE IMAGE (not simply one that meets your preset sharpness standard, which may not be the best possible). For that, there is only one app: OptimumCS-Pro, the unique optimum camera settings calculator (this is NOT simply a DoF calculator that "works backwards").
And if, in your landscape and architectural photography, you would like to achieve insanely huge depth of field, with astonishing image sharpness, try FocusStacker. Take the guesswork out of the focus stacking technique and achieve remarkably consistently (and excellent!) results.

Version history
6.0
2018-10-31
This update adds optional readout of image blur for objects at the extremes of depth of field and at focus (where image blur will be non-zero if you opt to include the effects of diffraction).
Why would this be useful? After all, image blur at the extremes of depth of field should simply be your specified circle of confusion. Well, not if you focus beyond the hyperlocal distance.
Some landscape photographers place greater emphasis on image sharpness for far objects (the horizon or, say, a line of trees on a ridge) than for near objects. They reason that the eye/brain expects distant objects to be sharp but can tolerate a wee bit of image blur up close. So they focus a little beyond the hyperlocal distance. Well, now you can have a readout of image blur and better judge where you would like to place focus.
By the way: You'll have the far limit pointer at infinity, but don't lock it in place. Locking it engages Hyperfocal Mode, which you don't want in this case.
The update also adds more flexible options with regard to switching off numerical readouts, for those who prefer a more minimalist interface — one that relies on the use of analog scales.
If you're new to TrueDoF-Pro, don't forget to check out the Links page where, among other things, you will find links to articles on image sharpness, depth of field, etc. You may end up looking at such things a little differently.

5.1
2018-10-28
This update fixes issues with hidden locks on iPhone 5s. Note that, due to the small screen of that device, a lock on the aperture slider is not available. The three locks for the distance sliders are available, and they're much more useful.
Don't forget all the great changes made in Version 5.0, which brought a HUGE increase in versatility and added entirely unique ways of working:
* In addition to the usual inputs, you can now directly set the near or far limit of depth of field — simply slide the relevant pointer.
* You may lock any input and then vary any other input.
It sounds so simple (hey, good design should always be simple), and yet this opens up all manner of different ways of working with depth of field. Just a couple of examples:
* A landscape or architectural photographer can specify a desired depth of field simply by setting the near limit of DoF, locking it in place, then setting the far limit (or vise-versa). TrueDoF-Pro will instantly display the focus distance and aperture that will give the required DoF. Yes, at last, a DoF calculator that can "work backwards!”
* A cinematographer can set the far limit of depth of field to the far end of the set, lock it in place, and then vary any other input (focus distance, near limit of DoF, aperture, focal length), knowing the background will always be sharp.
Explore the app and discover ways of working with depth of field that you never thought possible.
You’ll notice that one or other or both of aperture and focus distance need not be inputs — they can instead be outputs. Depth of field need not be an output — it can be an input. It all depending on what you want the app to do for you.
And you’ll find that everything can be done super-fast (no iterative fiddling to get the output you’re after). Just what a working professional needs!
Notice that the hyperfocal buttons have been removed in this version? That’s great — you can do the same things as before, but now in a much more intuitive manner via the lock feature: To enter Hyperfocal Mode, just slide the far limit pointer to infinity and lock it in place. Or, work a little differently if you like. Consider this: You have focused on an individual who you want to appear absolutely sharp. But you want the horizon behind her to be acceptably sharp. OK, a simple slide of a pointer sets the focus distance. A tap on its lock locks it in place. Slide the far limit pointer to infinity. Instantly, you see what aperture you need to set to get the results you want. Isn’t this ease and speed the sort of thing you want from a calculator? And it’s so nice to find that, because there is usually more than one way to do something, you can work the way you want to work!
There is much else that is new:
* For a cleaner interface, the slider “thumbs” are gone. You now set distances and aperture by directly sliding the pointers. (Note that you do not need to keep your finger on a pointer as you slide it — you can move your finger to the side as you slide, all the better to see where the pointer is pointing.)
* The button for numerical entry of focus distance via keypad has been moved to the left of the screen.
* If you have enabled the diffraction option, you can no longer select small apertures (large f-numbers) that result in so much diffraction that it overwhelms the reduction in defocus blur that small apertures bring.
* A more elegant colour scheme has been adopted. The inputs/outputs that directly correspond to settings that you would make on your camera are designated by discreet red dots. The other critical setting — blur spot diameter (circle of confusion) — is designated by a yellow dot.
* Plus… many other small changes, throughout the app.
Well, that’s probably enough (for now). Enjoy this exciting upgrade!

This update brings iOS 12 compatibility and support for the various new iPhone X models.
There are some very minor interface tweaks (e.g. buttons disappear if they move too close to the top or bottom of the screen).
Alas, that's about all. Just boring utilitarian stuff. For now...

• Numerical readouts are customisable (show, hide, display front and rear DoF as distances or %).
• Distance units are changed directly on the main screen by tapping the m / ft button.
• Your chosen blur spot diameter (circle of confusion) is displayed on the main screen.
• An optional "distance snap" function has been added, to make the distance slider even easier to use.
• The Settings screen has been simplified (but presents more options).

Some lovely, subtle changes to the artwork of various screens (or perhaps not so subtle changes, if you're paticularly attuned to such things).
3.0.1
2013-09-26
Fixed a bug: The hyperfocal function, accessed via the "HF" button, now works properly when a wavelength other than the default value is being used.
Added a warning symbol on the main screen to act as a reminder in cases where you have set a wavelength other than the default value.
Remember, the facility to set wavelength is designed for use by those photographers and cinematographers who are shooting in the infrared (or ultraviolet) part of the spectrum. For all other photography, the default wavelength value should be used.

Added the facility to set wavelength, a feature for those shooting in the infrared or ultraviolet part of the spectrum.
Redesigned the “Settings” screen: more settings, no clutter.
Refreshed the interface for an even cleaner, more elegant look.
Changed the action of the focal length scroll wheel:
- The scroll wheel now responds much faster when you tap the focal length “Up” and “Down” buttons.
- Scrolling now results in real-time update of depth of field output (rather than having to wait till the wheel settles on your final choice of focal length).
- The wheel no longer free rotates after you stop pushing it.
Changes required for iOS 7 compatibility.

Fixed a wee bug: For customers in Europe, the comma now functions correctly as the decimal separator when entering focus distance via keypad.
2.0
2013-07-29
In response to customer request:
* Added optional input via keypad for focus distance.
* Added numerical readout of near and far limits of depth of field (on the 4 inch screen).
The version that runs on the iPhone 5’s larger screen has longer sliders, making inputs even easier, and also offers a “useful range" option. This indicates the range of apertures that may be used before diffraction starts to reduce depth of field, and also shows the maximum depth of field that can be achieved.
Added a link to the new FocusStacker app.
Added a link to an index page of useful articles.
Numerous small tweaks

KSeek,
Superbly done!
The simplicity of the interface is both elegant and brilliant.
I would have been perfectly happy with the free version, but I want to reward the developer for such an awesome app, so I also purchased this paid version.

Perfect !!
Exactly what i needed!! Straight forward, simple, and fast. Not sure why the other guy said this app was "unusable" for not having predefined cameras in the app. You dont need that silly. Just know what sensor / film size you have. His lack of knowledge doesn't make this a bad app. This app works fantastic.

Great Teaching Tool
Using this app for just one day illuminated to me the value of it as a teaching tool. I used in class to show my photography students how the depth of field is impacted by various aperture settings and they instantly saw that old teachings were in fact incorrect: Narrower aperture IS NOT always better for the "long" shots. Now they can quickly find the best aperture setting to achieve the desired depth of field and surprisingly it typically falls well within the lens' sweet spot aperture range.
Fantastic tool for teaching AND use out in the field.

New features not working. No lock icons for depth sliders.
Needs more work.

unusable
unusable. there is no list of sensors or cameras with their particular circle of confusion.

I like it
This is a great tool for quickly estimating DOF for night shooting (DOF preview doesn't work so well in low light). It has presets for your favorite focal lengths.
I'm an amateur and find this very handy. Probably less handy for a pro who can reliably guesstimate DOF based on extensive experience.

Extremely useful
Very easy to use and intuitive. Helps you immensely plan your shot and achieve the desired outcome
anti-climax,
nice app
Beats the heck out of reading DOF scales on lenses. Love the update! Cleaner interface and easier to find hyperfocal.
PhotoGib,
Disappointed
Seems to be very similar to the free version. And, after paying $10 it encourages you to buy the other version where you can start with your desired depth of field. Don’t both with this one.

Excellent
Well implemented app. Easy to use. Nice looking. A great tool for explaining DOF.
